[android-developers] Getting the amount of Audio data buffered in the device

[KK]

I am trying to write a streaming application. I have my own decoder
and I am playing PCM audio using AudioTrack. At any point in time I
want to know how much data is buffered with the device. I want to use
this so that if the data with the device go below a level, I want to
go into a buffering mode where I will buffer 2-3 seconds of data
before continuing playback again. Can someone please tell me how to do
this?

Thanks in advance
KK

[android-developers] Problem with fwrite onto sdcard

[KK]

Hi,

  I am very new to Android. I am trying the following code in the
android ndk.

FILE* fp = fopen("/sdcard/test", "wb")
if(NULL == fp)
{
  return errno;
}
int written = fwrite("Test", 1, 4, fp);
if(4 != written)
{
  return -1;
}
fclose(fp);

return 0;

I am trying this on emulator and I have created and sdcard for the
emulator. The function returns 0. When I check the sdcard, a file with

[android-developers] Supported Media Formats Programmatically

[kk]

How do I determine programmatically which Media MimeTypes/Formats are
supported on a specific device/platform?

There doesn't appear to be any methods in Media Store or Media
Managers to determine supported types on device.

Is this by design or can we expect to see support in future releases?


Regards,

KK

[android-developers] Re: Supported Media Formats Programmatically

[kk]

Hi Ajeet,

Thanks for the reply.

This is great information, but unfortunately does not address my
question.

I am not certain that querying the Webkit interface gurantees that the
mimetype is support on across the platform, let alone via Webkit based
applications.

Documentation to sparse to determine.

Regards,

KK

[android-developers] Emulator: 1.6 SDK release Troubleshooting Proxy

[kk]

Hi All,

Trying to troubleshoot proxy, but  command as indicated in SDK
Emulator documentation results in invalid command prompt:

Documented Command:
emulator -verbose-proxy -avd

Error indicated:

  unknown option: -verbose-proxy
  please use -help for a list of valid options

In previous SDK releases (1.5)  the following undocumented command was
functional, but now does not post any messages when accessing
Network via Browser.

emulator -debug-proxy -avd mydevice


What is the appropriate command to troubleshoot proxy?

Is this a known issue and/or bug?


Rgds,

KK

[android-developers] triggering onCreate with a non-null Bundle (or onRestoreInstanceState) from the emulator

[kk]

Hi all,

I've recently done quite a bit of work on saving instance state and
restoring using parcelables for custom data structures.
My problem is that I don't know how to test this functionality on the
emulator. I can trigger calls to onPause and onStop for my activity
(if I navigate out of it) but never onDestroy. So, whenever my app
starts up, it starts with a null bundle. I've never had onCreate with
a non-null bundle and I've never had onRestoreInstanceState getting
called.

Can someone please tell me how I can test the restore state
functionality from the emulator?

cheers,
kk.

[android-developers] can an updated version of an app try to restore using a bundle containing older data?

[kk]

Hello all,

I'm trying to prevent the situation where an updated version of my app
restores using a bundle written from a previous version of my app. In
other words:

1) app v1 stops and calls onSaveInstanceState
2) app v1 saves the bundle (call it v1 data)
3) user goes to marketplace and updates the app to v2
4) user starts the v2 version of the app
5) v2 version calls onCreate passing the bundle with v1 data (i.e. the
one saved during step (2))

Is that even possible? Do I need to worry about it?

cheers,
kk.

[android-developers] JetPlayer keeps logging "write blocked for X msecs" - is this normal?

[kk]

Hello all,

I'm trying to add audio to my game and following the jetboy tutorial
and dev pages I'm doing it as follows:

I'm initialising like this:

JetPlayer JET_PLAYER = JetPlayer.getJetPlayer();
JET_PLAYER.clearQueue();
JET_PLAYER.loadJetFile(p_resources.openRawResourceFd(R.raw.ingame1));
byte sSegmentID = 0;
JET_PLAYER.queueJetSegment(0, -1, 0, 0, 0, sSegmentID);

then doing:

JET_PLAYER.play();

ingame1.jet only contains 1 segment, which is the track I'm trying to
play.
The audio plays ok but I keep getting these in logcat:

W/AudioFlinger(   31): write blocked for 49 msecs
W/AudioFlinger(   31): write blocked for 50 msecs
W/AudioFlinger(   31): write blocked for 54 msecs

They are quite frequent...3-4 of those per second. Is this normal or
am I doing something wrong?

cheers,
kk.

[android-developers] BroadcastReceiver and Google Services Inquiry

[kk]

Hi All,

I have been working on BroadcastReceiver code to capture GMAIL events
and try to extract data to create an email event log.

Although the registration of the BroadcastReceiver using
Intent.PROVIDER_CHANGED for gmail appears to be correctly formed and
no exceptions are generated.  I have my doubts whether the receiver is
able to capture gmail event for Intent.PROVIDER_CHANGED, generated
when unread email is available, since code in my BroadcastReceiver is
never activated.   Upon reading the BroadcastReciever API docs (see
excerpt below) I see that BroadcastReceivers are not designed to
capture intents used with startActivity() and that BroadcastReceivers
only receive intents generated from a sendBroadcast() method call.
For your reference see my code snippets below.

Is the BroadcastReceiver mechanism not the appropriate method to
capture email/gmail/sms events?



BroadcastReceiver code is the following:

public class EmailReceiver extends BroadcastReceiver {
/**
 *
 */

String TAG= "MY_TAG:RECEIVER";

@Override
public void onReceive(Context context, Intent intent) {
//
Log.i(TAG, "Action=" + intent.getAction());
  if (Intent.ACTION_PROVIDER_CHANGED.equals(intent.getAction
())) {
  Uri dataURI= intent.getData();
  String dataURIPath=dataURI.getPath();
  Log.i(TAG, dataURIPath);
   }
}
}


BroadcastReceiver code registration for gmail is the following:
//

@override
public void onCreate(Bundle b){


EmailReceiver myMailReceiver = new EmailReceiver();

..

}


@Override
public void onResume(){
super.onResume();

 try{
   IntentFilter mailFilter = new IntentFilter
( Intent.ACTION_PROVIDER_CHANGED, "content://gmail-ls/unread/^i");
   // IntentFilter mailFilter = new IntentFilter
( Intent.ACTION_PROVIDER_CHANGED, "gmail-ls");
registerReceiver( myMailReceiver, mailFilter);
Log.i(myMailReceiver.TAG, "MailReceiver registered");
  }catch(Exception e){
Log.e(myMailReceiver.TAG, "Intent Filter malformed");
  }

}

Excerpt from BroadcastReceiver Doc:

Base class for code that will receive intents sent by sendBroadcast
().



Note that, although the Intent class is used for sending and receiving
these broadcasts, the Intent broadcast mechanism here is completely
separate from Intents that are used to start Activities with
Context.startActivity(). There is no way for a BroadcastReceiver to
see or capture Intents used with startActivity(); likewise, when you
broadcast an Intent, you will never find or start an Activity. These
two operations are semantically very different: starting an Activity
with an Intent is a foreground operation that modifies what the user
is currently interacting with; broadcasting an Intent is a background
operation that the user is not normally aware of.

.

Regards,

KK

[android-developers] how to select listview from multiple listviews in main.xml (on Android 2.3.3)

[KK]

hi all,
I'm using FrameLayout and have defined two LinearLayouts embedded inside
the FrameLayout. Now for each LinearLayout I've a listview . The problem
I'm facing is picking the two listviews separately from my Java side code.
The default listivew in XML uses the standard defined ID as
*android:id="@id/android:list"
*and I'm not able to pick the right one. So I decided to give custom ids to
each of the list view like this in Layout1:
  

and the following in Layout2

  

and this is what I'm trying to use to pick the listviews separately,

  ListView listView1 = (ListView) findViewById(R.id.list1);
  ListView listView2 = (ListView) findViewById(R.id.list2);

With the above code in pace, I'm not getting any compilation errors. But
during run time I'm getting errors with this message:
*  java.lang.RuntimeException: Your content must have a ListView whose
id attribute is 'android.R.id.list'*

Are we not allowed to use custom IDs for listviews? If custom IDs are not
allowed, then what is the best way to handle the above problem? Would
appreciate if someone could point me to the right direction.

BTW, I'm actually trying to define two layouts each with its own listview
and then I'm trying to animate between two UI screens each using one layout
and the default behavior gives only one of the listivew as picked by
"getListView()" which happens to be the 1st one, so my 2nd UI page is not
showing any listview.


Thanks,
KK

Changing ListActivity to just Activity worked like a charm. You are a life
saver. Thanks a lot.

[android-developers] Using multiple listview inside one activity, how to give focus to each

[KK]

hi All,
I'm using multiple listViews inside one activity. I'm using each listiview
in its own UI screen layout, meaning I've two UI screens. Now when I start
the app, I get the focus on the first app as I'm able to scroll down/up the
list and when I switch to the 2nd listview in the 2nd UI screen, the second
listView works fine and I'm able to scroll the list. Next, when I return
back from the 2nd listview UI screen page to the first page screen, the
list becomes static/freezed and I'm not able to scroll up/down but
surprisingly when I return back to the 2nd listView, it still works fine.
I'm not able to understand as to why both the listViews work fine initially
but after returning back from the 2nd listView the 1st listView stops
working/scrolling. To me it feels as if something is locked in 1st
listView, when I'm returning back from the 2nd one and we've to enable some
short of flag, by saying "enable this listView from scrolling/usage as
currently this listView is in focus on screen". Would appreciate if someone
could point me to the right direction. I'm adding some code snippets below,

--
Activity file code snippet
--

layout01 = (LinearLayout) findViewById(R.id.Layout1);
  layout02 = (LinearLayout) findViewById(R.id.Layout2);
  layout02.setVisibility(View.GONE);

..
listView1 = (ListView) findViewById(R.id.list1);
  listView2 = (ListView) findViewById(R.id.list2);

this.adapter = new MovieAdapter(this);
  listView1.setAdapter(this.adapter);
  listView1.setItemsCanFocus(false);

  listView2.setAdapter(new MovieAdapter(this));
  listView2.setItemsCanFocus(false);



-
main.xml layout file:
-
http://schemas.android.com/apk/res/android";
android:id="@+id/container"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

http://schemas.android.com/apk/res/android";
android:id="@+id/Layout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
    android:orientation="vertical" >























Appreciate your time.

Thanks,
KK

[android-developers] Google App Engine and Users API and android By Nikolay Elenkov - 8:38am - 3 authors - 9 replies

[kk]

Hi!
I am developing Live Wallpaper for Android and stumbled upon scrolling
wallpaper issue.
We have
onOffsetsChanged(..) function with xPixelOffset argument.
Question is, what is the maximum value of xPixelOffset value and is it
documented somewhere? Many people considered it to be (screen width *
2) and successfully used it. I myself get same result (-480 with
screen width = 240). But is it the same for every device and will it
be the same?
I just couldn't find official documentation on this and i can't
understand the logic behind this. Phone has X home screens and screen
width = W. So why can't maximum offset be say, X*W instead of 2*W?
And another question is, doesn't it mean that total width equals 3
width? Considering that real drawing area starts with 0  and ends at W
and maximum offset is 2*W, last screen ends with point of X = (W +
2*W) = 3W.
I just can't work with 2*W value now because i don't know yet whether
it's a requirement for maximum offset on every device or is it just
some of them.
Thank you and sorry for my English.

Hi All,
Can someone tell me if its possible to move/scroll the notification message
from one direction to the other(say from right to left). If yes, then how to
achieve the same ?
Actually as part of my media player, I want to show current song title
through notification and as the space is small, I want to make it scroll so
that the enduser can see the full text being displayed through
notification.
Thanks for your time.

Using the example code I'm tyring to add a custom layout for notification,
but nothing shows up. Can anyone help me out?



RemoteViews contentView = new RemoteViews(getPackageName(),
 R.layout.mynotification);
 contentView.setImageViewResource(R.id.image, R.drawable.icon);
 contentView.setTextViewText(R.id.title, "Custom notification");
 contentView.setTextViewText(R.id.text,
 "This is a custom layout");
 Notification notification = new Notification();
 notification.contentView = contentView;
 Intent notificationIntent = new Intent(this, MusicDroid.class);
 PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
 notificationIntent, 0);
 notification.contentIntent = contentIntent;
 mNotificationManager.notify(notificationId, notification);

and the mynotificaiton.xml layout is like this:


http://schemas.android.com/apk/res/android";
android:id="@+id/layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp" >

problem I ran into is that, there is no direct support for hindi TTS. So, I
tried searching in google for various options on to get this thing done and
bumped into couple of interesting things like:

http://groups.google.com/group/tts-for-android/browse_thread/thread/ff5f891b5e3daaec

After going through the link mentioned therein, I could not figure out much.
Would appreciated if someone could point me in the right direction or help
me out on how to integrate raw TTS files for hindi in Android system. Any
other suggestion to achieve the same result is more than welcome.

Thanks,
KK

[android-developers] Screen Orientation changes automatically in 2.2 emulator

[KK]

Hi All,
I'm trying to create a simple stream media player app. Though the media
player is working fine and I'm able to play shoutcast stream, but I'm
facing a weird problem, screen orientation changes automatically in periods
of : 2mins of start of app---15 secs---15 secs---2minutes and the cycle
continues. The time is not 100% accurate, and just my observation. Would
appreciate if someone could point me what could be causing this problem.
Thanks for your time. Just a note, that I'm running the app on android
emulator and I'm on 2.2 API series.

[android-developers] Can we use a scrollview inside linear layout?

[KK]

hi All,
I'm not sure if the asking I'm asking is logical or wrong. Actually I'm
trying to achieve something like this:
1. The whole screen is divided into two parts, Upper half which takes 90%
of layout space and the lower half which is 10% of the space.
2. In the lower half I'm showing the progress bar for each song selected
from the Upper half.
3. In the upper half I'm trying to show all the songs in the sdcard
available. I'm trying to make this part scrollable as we can have lots of
song which wont fit in the given space.

I want the lower part to remain fixed irrespective of the current selection
in the Upper half, say for example if I'm playing the 50th song(out of 100)
then song will be in the middle of the Upper screen space where as the
lower half will continue to show the current song position.

Logically, I'm trying to do something like this in the layout file



  layout_weight=9
  sldjfsldf
 
   song lsit
 
 ..


 layout_weight=1
   sdljfsldjf





Please help me how to get this done. Would appreciate other ways of
achieving my end result by some other elegant approach.
Thanks in advance.

Regards,
KK

Re: [android-developers] Can we use a scrollview inside linear layout?

[KK]

Thanks for the quick tip, I'll try it out. I've a question though. Is it
the case that the lisview inherently supports scrolling when the no of
items grows bigger than the display area, and hence we don't need to sue
scrollview in this case? If that is the case then, as per your suggestion,
in my case if the no of items is say 50 then they will automatically be
scrollable, right? Please rectify if I'm wrong.

Thanks,
kk

[android-developers] does android.media.Mediaplayer support asf stream playing ?

[KK]

hi All,
I was just trying to figure out, if there is any option for playing ASF
streams. I tried searching in google but couldn't find any solid answer.
Would appreciate if someone can let us know if the the inbuilt
mediaplyer( android.media.MediaPlayer) supports playing this format, can we
play asf stream media similar to other formats like shoutcast mp3 etc.
Also, it would be helpful if someone can point me to the proper
URL/tutorial for playing asf streams. Actually I'm trying to write a small
app that plays couple of stream media formats.
Appreciate your time.

Thanks,
KK

[android-developers] ListView text goes black when scrolling the content

[KK]

Hi All,
I'm trying to show a list of songs using ListView (which supports scrolling
when the song list grows bigger than the available screen). In this regard,
I'm able to show the list of songs but whenever the user tries to scroll
the screen up/down the part of the screen which has the text,  goes black
 as can be seen here (and is not readable):
  http://imageshack.us/photo/my-images/706/device2025132814.png/
  http://imageshack.us/photo/my-images/17/device2025132731.png/

Only when the user is done scrolling then dark portion goes out and the
screen starts showing the song list normally and is readable. I've tested
this on Android 2.3.4 real device. Would appreciate if someone could point
me what is going wrong here.

The code snippet for generating the song list is as below:

snippet


http://schemas.android.com/apk/res/android";
android:background="@drawable/statue_of_liberty_600x800"
 android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
 
 

 
 


----snippet---


Appreciate your time. Thanks.

KK

[android-developers] Trying to exit app( using finish() ) gives ANR on device but not on emulator

[KK]

hi All,
I'm trying to exit the application using the following code in my
mediaplayer app. While it works fine in the emulator(2.2) but when I run
the app on an actual device (with 2.3.4 ) it gives me ANR error. Would
appreciate if someone can point me what is going wrong.

code snippet-
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
...

case R.id.exit:
Log.d(TAG, "Shutting down the service");
 if (mMediaPlayer != null) {
 mMediaPlayer.release();
mMediaPlayer = null;
// remove all notifications
 mNotificationManager.cancelAll();
timer.cancel();
finish();
 return true;


---code snippet-
Just a note that I'm using notifications to show current song being played,
using Timer for continuously updating the seekbar for the current song
being played.

Appreciate your time. Many thanks.

Regards,
KK

code to play a user-selected song



try {

mMediaPlayer.setDataSource(filename);
 mMediaPlayer.prepare();
mMediaPlayer.start();
showNotification(finalPosition);
 Log.d(TAG, "duration: " + mMediaPlayer.getDuration());

timer.schedule(new TimerTask() {

mMediaPlayer.setOnCompletionListener(new OnCompletionListener() {

@Override
 public void onCompletion(MediaPlayer arg0) {
nextSong();
}
 });
} catch (Exception e) {
e.printStackTrace();
 }



As the error is pointing to this line
   *if (null != mMediaPlayer && mMediaPlayer.getCurrentPosition() <

*

something is wrong here but surprisingly this is working fine on emulator
without any such error, any idea how is that possible?
 Thanks for your help.

[KK]

hi Pskink,
That actually worked, I moved the timer.cancel() before releasing the
mediaplayer. But what is the logical reasoning behind this, would you mind
explaining in a word or two? or may be point me to any web reference that
explains the thing. Thanks in advance.

shown. However in the code I'm using, as shown below opens up a new
instance of the app instead of leading the user to the currently running
one:

---code snippet
mNotificationManager = (NotificationManager)
getSystemService(NOTIFICATION_SERVICE);
// //Add current song to notification bar
 CharSequence tickerText = "Demo Alert";
long when = System.currentTimeMillis();
 CharSequence contentTitle = "Now playing";
CharSequence contentText = "Demo song";
 PendingIntent pendingIntent = PendingIntent.getActivity(
getApplicationContext(), 0, new Intent(this,
 DemoPendingIntentActivity.class), 0);

Notification notification = new Notification(
 R.drawable.ic_stat_playing, tickerText, when);
notification.setLatestEventInfo(getApplicationContext(), contentTitle,
 contentText, pendingIntent);
notification.contentIntent = pendingIntent;
 // Make the notification non-clearable
notification.flags = Notification.FLAG_ONGOING_EVENT;
 mNotificationManager.notify(notificationId, notification);
---code snippet

How do I open up the currently running activity instead of opening a new
one? Please let me know whats going wrong in the above code. Appreciate
your time.

Thanks,
KK

Re: [android-developers] How to use PendingIntent to open existing activity and not a new one

[KK]

Thanks for the hints. I'm trying to use the FLAG_ACTIVITY_REORDER_TO_FRONT
flag but the behavior remains as earlier. After the activity starts, I
press "Menu" to go to home and then pull down the "Notification list" click
on the current one (for my demopendingintent activity) and it brings me a
new activity page. I've added exit buttons and logs through which I'm able
to conclude that it starts a new activity rather than bringing the one
running in the background. May be I'm doing something wrong in my code.
Please find below the code snippet I'm using for showing notifications etc.

---code snippet

private void showNotification() {
mNotificationManager = (NotificationManager)
getSystemService(NOTIFICATION_SERVICE);
 // //Add current song to notification bar
CharSequence tickerText = "Demo Alert";
 long when = System.currentTimeMillis();
CharSequence contentTitle = "Now playing";
 CharSequence contentText = "Demo song";

Intent notificationIntent = new Intent(this,
 DemoPendingIntentActivity.class);
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT);

PendingIntent pendingIntent = PendingIntent.getActivity(
getApplicationContext(), 0, notificationIntent, 0);

Notification notification = new Notification(
R.drawable.ic_stat_playing, tickerText, when);
 notification.setLatestEventInfo(getApplicationContext(), contentTitle,
contentText, pendingIntent);
 notification.contentIntent = pendingIntent;
// Make the notification non-clearable
 notification.flags = Notification.FLAG_ONGOING_EVENT;
mNotificationManager.notify(notificationId, notification);
 }


*and the onCreate() is given below:*

public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
setContentView(R.layout.main);

 mButton = (Button) findViewById(R.id.button1);
mButton.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
 Log.d(TAG, "Shutting down app");
finish();

 }
});

showNotification();
 }

--- code snippet

Would appreciate if someone can point me whats going wrong here. Many
thanks.

Regards,
KK

[android-developers] Does the mediaplayer keep running even in orientation change ?

[KK]

hi All,
I'm working on a small app where I'm trying to play one mp3 media using the
default mediaplayer (android.media.MediaPlayer). In this regard, I wanted
to know, does the mediaplayer keep running even when the orientation
changes? I think, since the mediaplayer runs as a service, it must be
running until we manually release the mediaplayer using something like:
mMediaPlayer.release(). Would appreciate if someone can point me in the
right direction.

Actually, I'm trying to understand how to save states and what all I've to
save during orientation change. As a sample I'm able to save the state of a
continuously updating seekbar during orientation change and wanted to
implement the same feature for media player as well. I don't think we'll
have to stop and restart the mediaplayer during orientation changes. I even
tried the default player on my android device and I did not notice any such
lag during orientation changes, it just plays smoothly.

Appreciate your time.


Thanks,
KK

[android-developers] how to show numbers before each string in ListView

[KK]

Hi All,
I'm just trying to list song items and displaying it to user for selection.
I'm using the following ListView for this purposes:



and this list down the songs like this:
songa
songb
songc

Is there any option maybe shomething like android:numericlist which will
list the songs like this:
1.songa
2.songb
3.songc

Or may be some other elegant yet simple way to achieve the same effect.

Any help would be highly appreciated.

[android-developers] How to use SensorSimulator @ http://code.google.com/p/openintents/wiki/SensorSimulator

[KK]

Hi All,
Can someone help me on how to use the SensorSimulator @
http://code.google.com/p/openintents/wiki/SensorSimulator
I went through the instructions at the above wiki page, regarding
adding/using the SensorEventListeners and other Sensor related classes from
this package, but when I tried this :

   - Replace the following code in onCreate():

   mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);

   - by this code

   mSensorManager = SensorManagerSimulator.getSystemService(this,
SENSOR_SERVICE);



I'm getting error messages saying:
Type mismatch: cannot convert from SensorManagerSimulator to
SensorManager

Also for the registerListener() and unreigsterListener(), I'm getting this
error:
 The method unregisterListener(SensorListener) in the type SensorManager
is not applicable for the arguments (ShakeActivity)   // My Activity is
named ShakeActivity

Can someone help me how to fix these errors and use the SensorSimulator to
simulates movements/shakes etc.

Thanks in advance.

Hi Adam,
Thanks for the quick help. You are right, once I changed the mSensorManager
to be an instance of SensorManagerSimulator, it worked like a charm.
Thank you.

[android-developers] how to recursively search for media(mp3) files in sdcard

[KK]

Hi All,
This is related to a sample media player I'm write as part of learning more
of Android. For this, I'm trying to write some simple method to recursively
crawl the sdcard in all foders and create a list of all mp3 files, which I
can make use of later for playing the same. I tried google to find some
efficient way to do the same, but found that most of them are suggesting
having your own recursive method to the same. I also bumped into this URL @
http://stackoverflow.com/questions/3289649/recursively-add-files-in-java-speed-issue
but
don't know how to use the idea presented therein in a efficient wayy. Would
appreciate if someone could help me getting this. Any working example for
the same would be very helpful.

Thank you.

As part of my basic mp3 player, I'm using the inbuilt media player to play
songs. The problem I'm facing is that, though I'm able to get "TITLE" but
during playing the song, when I query for "DATA" field as below ( the full
code for quick viewing is give below.)

*private void playSong(int position) {*
* try {*
* int column_index = mCursor*
* .getColumnIndexOrThrow(MediaStore.Audio.Media.DATA);*
* mCursor.moveToPosition(position);*
* String filename = mCursor.getString(column_index);*
* Log.v(TAG, "Current Title:" + mCursor.getString(column_index));*
* if (mp.isPlaying()) {*
* mp.reset();*
* }*
* mp.setDataSource(filename);*
* mp.prepare();*
* mp.setOnCompletionListener(new OnCompletionListener() {*
* // Setup listener so next song starts automatically*
* @Override*
* public void onCompletion(MediaPlayer arg0) {*
* nextSong();*
* }*
* });*
* mp.start();*
* } catch (Exception e) {*
* Log.e(TAG, "Exception in playsong():" + e.getMessage());*
* }*
* }*

its giving me the following errors:
09-27 21:29:30.980: ERROR/Mp3Player(633): Exception in playsong():*column
'_data' does not exist*

Is there any way, I can get around with this and still play these mp3 files.
The mp3 files I'm using are the ones commonly available on the web and might
be missing the metadata.

Any help would be appreciated.

Thanks,
KK

[android-developers] Re: how to play media files(mp3) with some missing metadata

[KK]

Hi,
In this regard, I was just thinking, if I can somehow map the
MediaStore.Audio.Media.TITLE
to its corresponding absolute path, I should be able to play it without
issues(my earlier version of playSong() method was doing just that), but I'm
not yet to find a way to do that. Would appreciate if someone can point me
in the right direction.

Thanks,
KK

[android-developers] How to capture sensor moves using SensorSimulator

[KK]

Hi All,
Can someone explain about how to capture a particular movement, meaning
there must be some mechanism to capture the changes in X,Y and Z
co-ordinates and other things calculate the corresponding acceleration etc
and then set the threshold for your required shake/move. If I want to try a
new shake, how to do I set the threshold value, what is the usual process?

I was wondering, is there any way we can use enable SensorSimulator and let
it capture all the sensor parameters during shake/move and then pick those
recorded values and set your threshold. I think this must
be repetitive process, if someone wants to tune the threshold value. Would
appreciate if someone can throw some light on this.


Thanks,
KK

Re: [android-developers] Re: How to capture sensor moves using SensorSimulator

[KK]

Thanks for your response.
Is there any documentation on the web that contains some of the
parameters(already tuned to some extent) that I can try with. For instance I
found couple of examples talking about shake and there is a mention of:
(accelationSquareRoot >= 2) means shake detected,
This is the complete code for this:

public void onSensorChanged(SensorEvent event) {
// TODO
if (event.sensor.getType() == Sensor.TYPE_ACCELEROMETER) {
 float[] values = event.values;
// Movement
float x = values[0];
 float y = values[1];
float z = values[2];

float accelationSquareRoot = (x * x + y * y + z * z)
 / (SensorManager.GRAVITY_EARTH * SensorManager.GRAVITY_EARTH);
long actualTime = System.currentTimeMillis();
 if (accelationSquareRoot >= 2) //
{
if (actualTime - lastUpdate < 200) {
 return;
}
lastUpdate = actualTime;
 // Shake Detected
// TODO: do something
 }

}
}

Thanks in advance.

Regards,
KK

Hi All,
I just copied this code from the web and trying to run it in Eclipse gives
me errors, the R.id.listView and R.layout.main are not getting resolved. No
idea whats going wrong here.

 String number = cursor.getString(numberIndex);
list.add(name + ": " + number);
 } while (cursor.moveToNext());

// Get the list view
ListView listView = (ListView) findViewById(R.id.listView);
 ArrayAdapter aa = new ArrayAdapter(this,

Would appreciate if someone could explicitly mention what exactly is
the fix for this error. As, I don't see any mention of compoundbutton
and the user has correctly used  RadioGroup.OnCheckedChangeListener
I'm stuck at the same point.

Re: [android-developers] Re: OnCheckedChangeListener not working on RadioGroup

[KK]

I got it!. during creating the oncheckedchangelistener(), specifying
"new  RadioGroup.OnCheckedChangeListener()" instead of
just  "OnCheckedChangeListener()" fixed the problem.

Adding the sample code for others reference.

RadioGroup rdGroup = (RadioGroup) findViewById(R.id.rdbGp1);
rdGroup.setOnCheckedChangeListener(*new RadioGroup.OnCheckedChangeListener()
* {

@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
 // TODO Auto-generated method stub

}
});


Thanks to all of you.

[android-developers] In AutoCompleteVeiw calling setAdapter() and setThreshod() gives error

[KK]

Hi All,
I'm trying a sample code available on the web, in which I'm trying to test
AutoCompleteView. When trying to call setAdapter() method in following
lines:

*autoCompTxt.setAdapter(arrayAdapter);*
* autoCompTxt.setThreshold(3);*

I'm getting the following errors;

*Multiple markers at this line*
* - Syntax error on token "arrayAdapter", VariableDeclaratorId expected
after *
* this token*
* - Syntax error on token(s), misplaced construct(s)*

The code for the main Activity is as below:

*package com.demo.autocomp;*
*
*
*import android.app.Activity;*
*import android.os.Bundle;*
*import android.widget.ArrayAdapter;*
*import android.widget.AutoCompleteTextView;*
*
*
*public class AutoCompleteDemoActivity extends Activity {*
* private final static String[] presidents = { "Dwight D. Eisenhower", "John
F. Kennedy",*
* "Lyndon B. Johnson", "Richard Nixon", "Gerald Ford",*
* "Jimmy Carter", "Ronald Reagan", "George H. W. Bush",*
* "Bill Clinton", "George W. Bush", "Barack Obama" };*
*
*
* /** Called when the activity is first created. */*
* @Override*
* public void onCreate(Bundle savedInstanceState) {*
* super.onCreate(savedInstanceState);*
* setContentView(R.layout.main);*
* }*
*
*
* AutoCompleteTextView autoCompTxt = (AutoCompleteTextView)
findViewById(R.id.autoCompleteTextView1);*
* ArrayAdapter arrayAdapter = new ArrayAdapter(*
* getApplicationContext(),*
* android.R.layout.simple_dropdown_item_1line, presidents);*
* autoCompTxt.setAdapter(arrayAdapter);*
* autoCompTxt.setThreshold(3);*
*}*


The corresponding res/layoute/main.xml is as below(there is no errors in
main.xml, just posting for reference purposes):

**
*http://schemas.android.com/apk/res/android"*
* android:orientation="vertical" android:layout_width="fill_parent"*
* android:layout_height="fill_parent">*
* *
* *
* *
* *
**

Would appreciate if someone can point me what is wrong here or how to fix
the error and make the code work.

Thanks,
KK

[android-developers] Android source code not available at official site

[KK]

Hi All,
I was trying to download the android source code and play around with
things. I'm trying to use this like
   http://source.android.com/source/downloading.html

to get the source code. It seems the URL is unavailable and the 404 page
comes up . I also tried to access the page manually at @
https://android.git.kernel.org/repo
but the page is not available. Is there any alternative for the same.

Would appreciate if someone can point me in the right direction to get the
(latest)android source code. Thanks a ton.

[android-developers] How to pull information like current song, user-count etc from shoutcast URL in Android

[KK]

Hi All,
I'm not sure if my question fully belongs to this dev group, apologies for
any mistake.

As part of my stream media player development, I''m done with playing the
stream media, using the standard/default media
player(android.media.MediaPlayer) available as part of android OS. Now the
next feature I'm trying to add to this app, is to show the current song
being played, user count connected to the shoutcast sever etc. I tried to
google around and found something:

http://www.hrupin.com/2011/02/27/example-of-streaming-mp3-mediafile-with-android-mediaplayer-class
   http://www.smackfu.com/stuff/programming/shoutcast.html

Went through the link, but not able to figure out much. I found the
explanation in 2nd link above quite useful but don't know if there is
exiting third party utility. Actually, I'm thinking of some third party
JAR/utility which might be providing some simple API calls, say with the
shoutcast URL and provides the basic information like: current song, stream
speed say in kbps, listening user count etc.

Any help would be highly appreciated.

Thanks for your time.

Hi All,
I've not tried the stramscrapper one available @
http://code.google.com/p/streamscraper/, however, I bumped into one more
metadata scrapper and found it to be working fine(some minor glitches here
and there). You can find the same here:
   http://uniqueculture.net/2010/11/stream-metadata-plain-java/

Hope someone will find this useful.

Thanks,

[android-developers] How does android decide to cache a process?

[KK]

In Gingerbread Settings->Applications->MyApplications, the Running tab
has been divided into two. Running Services and Cached Background
Process. So how and when does Android decide to cache a process?
Mainly is there anything my app can do to tell the system to never
cache my process?

Thanks

[android-developers] Button in Custom Preference gets enabled automatically

[KK]

I have a custom preference in my application which consists of a
textview and a button and it is put in a preference screen. I load the
layout in the onCreateView of the preference

LayoutInflater inflater =  (LayoutInflater)getContext().
 
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.custom_preference, parent,
false);

In my xml, I have put android:enabled="false" for the button because I
want to disable it and enable it conditionally later. When my
preferencescreen comes up, this button is disabled, but gets enabled
automatically in a second(I still haven't added any code to enable
this yet).

Also I find that the onCreateView of my custom preference keeps
getting called again and again.

Can someone please help me as to what is happening here?

[android-developers] How does Android EditText store the content internally

[KK]

Hi,

  I have an android EditText which holds a password. I have to
retrieve this in one of my modules and pass it to another. I am
calling EditText.getEditableText and encrypting its content. But I
want to know if android creates any immutable objects internally for
the EdiText Content(like String), in which case there might still be a
way for a hacker to get the password out?

[android-developers] SoftKeyboard - not showing the auto suggest

[KK]

I am going to do an android application. In that app, I have to add the 
customized keyboard.
So that I am trying to create my own customized keyboard. I found the code 
for the keyboard from the android sdk's sample(SoftKeyboard).
When I execute the code, the keyboard is installed and showing in my app.

The problem is,
1) The keyboard is installed and can access by all the apps. But I want to 
install it only for my app.
2) And the keyboard is not giving the auto-suggest words. So How can I show 
the auto-suggest words in that SoftKeyboard.

[android-developers] Android Pinch zoom not working over imageview inside gesture overlayview

[KK]

I am doing the following in my application.

1) Display a image in a activity.

2) Recognize gesture over that image.

3) And also doing pinch and zoom over the same image.

The layout I have created is given below.

**
*http://schemas.android.com/apk/res/android"*
*android:layout_width="fill_parent"*
*android:layout_height="fill_parent" >*

**
**

**

And I am using the following code for the "pinch zoom" and "gesture 
overlayview" (detect the gesture).

*public class Touch extends Activity implements OnTouchListener {*
*private static final String TAG = "Touch";*

* // These matrices will be used to move and zoom image*
* Matrix matrix = new Matrix();*
* Matrix savedMatrix = new Matrix();*

* // We can be in one of these 3 states*
* static final int NONE = 0;*
* static final int DRAG = 1;*
* static final int ZOOM = 2;*
* int mode = NONE;*

* // Remember some things for zooming*
* PointF start = new PointF();*
* PointF mid = new PointF();*
* float oldDist = 1f;*

* @Override*
* public void onCreate(Bundle savedInstanceState) {*
* super.onCreate(savedInstanceState);*
* GestureOverlayView gestureOverlayView = new GestureOverlayView(this);*
* View inflate = getLayoutInflater().inflate(R.layout.main, null);*
* gestureOverlayView.addView(inflate);*

* ImageView img = (ImageView) inflate.findViewById(R.id.showImg);*
* img.setScaleType(ImageView.ScaleType.FIT_CENTER);*
* img.setOnTouchListener(this);*

* setContentView(gestureOverlayView);*
* }*

* public boolean onTouch(View v, MotionEvent event) {*
* ImageView view = (ImageView) v;*
* view.setScaleType(ImageView.ScaleType.MATRIX);*
* float scale;*

* // Dump touch event to log*
* dumpEvent(event);*

* // Handle touch events here...*
* switch (event.getAction() & MotionEvent.ACTION_MASK) {*

* case MotionEvent.ACTION_DOWN: // first finger down only *
* Log.d(TAG, "mode=DRAG");*
* mode = DRAG;*
* break;*
* case MotionEvent.ACTION_UP: // first finger lifted*
* case MotionEvent.ACTION_POINTER_UP: // second finger lifted*
* mode = NONE;*
* Log.d(TAG, "mode=NONE");*
* break;*

* oldDist = spacing(event);*
* Log.d(TAG, "oldDist=" + oldDist);*

* midPoint(mid, event);*
* mode = ZOOM;*
* Log.d(TAG, "mode=ZOOM");*

* } else if (mode == ZOOM) { // pinch zooming*
* float newDist = spacing(event);*
* Log.d(TAG, "newDist=" + newDist);*
* if (newDist > 5f) {*
* matrix.set(savedMatrix);*
* scale = newDist / oldDist; // thinking i need to play around*
* // with this value to limit it*
* matrix.postScale(scale, scale, mid.x, mid.y);*
* }*
* }*
* break;*
* }*

* // Perform the transformation*
* view.setImageMatrix(matrix);*

* return true; // indicate event was handled*
* }*

* private float spacing(MotionEvent event) {*
* float x = event.getX(0) - event.getX(1);*
* float y = event.getY(0) - event.getY(1);*
* return FloatMath.sqrt(x * x + y * y);*
* }*

* private void midPoint(PointF point, MotionEvent event) {*
* float x = event.getX(0) + event.getX(1);*
* float y = event.getY(0) + event.getY(1);*
* point.set(x / 2, y / 2);*
* }*

* /** Show an event in the LogCat view, for debugging */*
* private void dumpEvent(MotionEvent event) {*

* || actionCode == MotionEvent.ACTION_POINTER_UP) {*
* sb.append("(pid ").append(*
* action >> MotionEvent.ACTION_POINTER_ID_SHIFT);*
* sb.append(")");*
* }*
* sb.append("[");*
* for (int i = 0; i < event.getPointerCount(); i++) {*
* sb.append("#").append(i);*
* sb.append("(pid ").append(event.getPointerId(i));*
* sb.append(")=").append((int) event.getX(i));*
* sb.append(",").append((int) event.getY(i));*
* if (i + 1 < event.getPointerCount())*
* sb.append(";");*
* }*
* sb.append("]");*
* Log.d(TAG, sb.toString());*
* }*
*}*

The issue is mentioned below.

The zoom is not working perfectly. sometimes, I do a pinch or zoom, it is 
not working. 

**NOTE: But when I remove the "GestureOverlayView", the pinch and zoom 
working perfectly over that imageview. But I need "GestureOverlayView" to 
detect gesture.**

Is this a android issue or the coding issue? How can I fix this?

[android-developers] Wifi drop Issues on Motorola Droid

[KK]

I am trying to develop a streaming application and I am testing it on
multiple devices. But I am seeing some problems on Motorola Droid with
regards to wifi connection. The wifi connection drops occasionally and
comes back in 30 seconds to 1 minute on the Droid. Sometimes while in
the middle of streaming I get network connection errors even though I
am standing very next to the wifi router. I am not finding this
problem with any other devices. Has anyone found any similar issues
with the Droid? Any idea what can be done in my program to fix this?

Thanks

[android-developers] How to set and get thread priority from Java and native layers

[KK]

I have a multithreaded streaming app which has mainly the following 5
threads

1 Main App(UI) Thread
1 controller thread (in native)
1 audio decoder thread (in native)
1 video decoder thread(in native)
1 thread to query the head position of audio (in Java)
 Apart from this I have video rendering with OpenGL.

My problem is, if I query the thread priority using the
Thread.getPriority method (my native threads make callbacks to Java
and I am making the query at that point of time), I am getting the
priority of each of them as 5. For my audio query thread (the last one
in the list) I am explicitly setting the priority using
Process.setThreadPriority(Process.THREAD_PRIORITY_URGENT_AUDIO);

Also for my decoder threads, I am giving higher priority than my
controller thread(using pthread APIs in native). But still finally all
of them seem to have same priority.

Can anyone please tell me what is wrong here. Also what should I be
doing to increase the priority of my threads(both from Java and
native).

Thanks
KK

Ok, finally I seem to have found out some more of what is happening. I
am able to set any priority > 0. But if I try priorities <= 0 it
throws an exception. For all my practical purposes, positive
priorities are enough. But anyone has any idea what application is not
allowed to use any priorities <= 0?

Thanks

[android-developers] adding audio to a game - triggerClip for SFX

[kk]

Hi all,

I'm using JetPlayer in order to add some audio to a game I'm
developing.
Using the examples in JetBoy I have managed to create a .jet file
using JetCreator and play an audio track.
So far so good. However, I'm having some trouble playing sound effects
for my game.

I have a set of very small .mid files, each containing a shooting
sound for a different weapon.
However, when I try to add the .mid file in JetCreator I get
   "The segment starting and ending times are illogical"
I'm guessing this is because the clip is too short and starting/ending
M/B/T are both 1/1/0 ?

The idea was to add these SFXs and then use triggerClip to play them.
My question is, background music aside (I can make that work) what's
the best way to add SFX in a game
so that you can trigger them at any point programmaticaly? (i.e. have
something like playShootingSFX1(),
playShootingSFX2(), etc. that will go and play the SFX immediately).

thx in advance,
k.

[android-developers] Re: adding audio to a game - triggerClip for SFX

[kk]

Dave,

Thank you for your quick response. SoundPool is indeed the right way
to go
and I've got my SFX playing...pretty straight forward interface.

A small problem I'm having is that during playback I get a lot of:

W/AudioFlinger(   31): write blocked for 50 msecs

Also, although my (relative short) SFX are playing, the background
music fails with:

E/AudioCache(   31): Heap size overflow! req size: 1050624, max size:
1048576

This same audio track worked fine with JetPlayer. Any idea why
SoundPool thinks it's too big?

cheers,
k.

[android-developers] media player not looping properly

[kk]

Hi all,

I'm trying to play a looping background track in my app and it doesn't
loop.
The track starts playing and once it reaches the end all I hear is a
weird crackly sound for a split second and then nothing else.
Logcat doesn't show anything useful at the time. No errors/warning/
exceptions/etc.

Here's how I'm doing it...
During initialisation I call this:

public static MediaPlayer MEDIA_PLAYER;

private static boolean initMusicPlayer(InGameView p_inGameView)
{
MEDIA_PLAYER = MediaPlayer.create(p_inGameView.getContext(),
R.raw.bgmusic);
MEDIA_PLAYER.setOnErrorListener(
new MediaPlayer.OnErrorListener() {
public boolean onError(MediaPlayer p_mp, int 
p_what, int
p_extra)
{
Log.e("MEDIA_PLAYER", "ERROR: 
MediaPlayer: (" + p_what +")
with extra (" + p_extra +")" );
return false;
}
});

MEDIA_PLAYER.setLooping(true);

return true;
}

Then, in the surfaceChanged of my InGameView (i.e. when things are
good to go), I call

  MEDIA_PLAYER.start();

Can you guys see anything wrong with the above? Any ideas what could
be causing this?
All help greatly appreciated.

cheers,
kk.

[android-developers] Understanding DDMS allocations - stopping the GC from working overtime!

[kk]

Hi all,

I'm writing a game and I'm trying to avoid the GC kicking in and
causing big framerate drops.
I've run DDMS to see what allocations I'm causing and the huge
majority of them seem to fall under 2 categories:

1) class java.lang.String, allocated in java.lang.Integer, allocated
in toString
2) class java.lang.String, allocated in
java.lang.AbstractStringBuilder, allocated in toString

In my game I need to display some stats so there are a few number-to-
string operations.
I went the StringBuilder way with pre-allocated buffers assuming this
will help reduce allocations.

So for example I have a

private StringBuilder m_hitRatio - new StringBuilder(8);

I draw using
canvas.drawText(m_hitRatio.toString(), x, y, paint);

I update using
m_hitRatio.replace(0, 8, String.valueOf(calculatedHitRatio));

In some cases if I'm passing a normal string to a method I also use
Integer.toString(myValue);
I'm guessing all of the above is the reason my GC is working overtime!
Are there better ways (using canvas) to manipulate and render text/
numbers on screen?

cheers,
kk.

[android-developers] Game performance degrading over time - any ideas?

[kk]

Hi all,

I've written a game and I've noticed that after playing for about
20-30 minutes the performance starts degrading.
By performance degradation I mean my average frames-per-second seem to
slowly drop.
I've no idea what could be causing this so any help would be greatly
appreciated.

I'm doing all my allocs at the beginning and the only things that
alloc in game according to DDMS are
Integer.toString operations (for integer values I need to draw with
drawtext) and setBounds on some drawables.
(I've no idea how to stop these from happening, so again, if you know
a way around this please do tell).

I'm calling System.gc() periodically, when I know not much is going on
in-game (e.g. between waves of enemies).
I'm doing this in order to avoid GC from happening during critical
gameplay periods.

If you know the answer to any of the following, please do tell (even a
guess would do :)):

+ Why is performance degrading with time? What could be causing this?
+ Is there a way to avoid allocs due to Integer.toString and
Drawable.setBounds calls?

Thank you in advance,
kk.

[android-developers] Re: Game performance degrading over time - any ideas?

[kk]

Hey all,

Thank you for your replies. I don't use SQLite or the Preference
editor.
The string lookup is definitely something worth considering.

In terms of profiling, I do:

Debug.startMethodTracing("g1");

in OnCreate and then stop tracing in OnDestroy.
Are you saying that I should create 2 trace files,
say one for the first half and one for the second half
of the game and compare the results?

Sounds like a good plan - I just have no clue as to what
could be causing this degredation :(

cheers,
kk.

[android-developers] Re: Game performance degrading over time - any ideas?

[kk]

DanH,

I've had a look at the allocations using DDMS. The only things that
are being allocated during the game (that I have control over) are
Integer.toString and Drawable.setBounds calls.

Also, I calling System.gc() periodically and it logs the time taken
to do the collection...It doesn't seem to be increasing with time.

I'll try profiling as suggested by Dianne but this is very weird and
is holding up my release :(

cheers,
kk.

[android-developers] Re: Game performance degrading over time - any ideas?

[kk]

Just to make sure, can someone please tell me if I'm misusing
StringBuilder here.
This is what I do:

private StringBuilder m_healthString = new StringBuilder(8);

I update by doing:
m_healthString.replace(0, 8, Integer.toString(myHealth));
Is this expensive/wrong? Is there a better way to update a
StringBuilder with a new String?

I render by doing:

myCanvas.drawText(m_healthString, ...); // this is using the char[]
version, which is good

Obviously I will look into a custom version of Integer.toString, which
will
eliminate quite a lot of the allocations in there.

cheers,
kk.

Top stuff Kostya/Dianne. Thank you for the feedback.
I think before I look into anything else, I should do this first to
get
rid of the thousands of micro-allocations that take place there.

UI elements are drawn about 20 times per second and although I cache
values that don't change, a lot of the values do change quite
frequently.

I'll report back if I'm still having issues after I do this.

Thanx again,
kk.

[android-developers] Re: Game performance degrading over time - any ideas?

[kk]

Hi all,

Got rid of all the Integer.toString allocations by having my own
intToString method and using char[] as suggested.
The only thing showing now on the DDMS allocs are the
Drawable.setBounds calls (lots of them).
I've used both the rect version and the four-ints version of setBounds
but they both do the same thing.
I'll post some code in case someone can tell me what I'm doing wrong:

private AnimationDrawable m_animationDrawable;
m_animationDrawable = (AnimationDrawable)
m_inGameView.getResources().getDrawable(p_animDrawableID);

then my doDraw method looks like:
final void doDraw(final Canvas p_canvas, final Rect p_bbox, final
boolean p_applyColorFilter)

and it does the following:
m_animationDrawable.getFrame(m_currentFrame).setBounds(p_bbox.left,
p_bbox.top, p_bbox.right, p_bbox.bottom);
// some color filter stuff that's irrelevant to the leak go here
m_animationDrawable.getFrame(m_currentFrame).draw(p_canvas);

// m_currentFrame gets updated in doUpdate
// p_bbox is a rect that represents the drawable's bounding
box...different frames can have different bbox sizes (e.g. during an
explosion)

The call to setBounds above shows as an alloc in DDMS :(
I've called it passing p_bbox directly as well (i.e. the rect version
of setBounds) and it makes no difference.
How can I prevent the allocation there?

Thank you in advance,
kk.

[android-developers] Can I stop background apps from causing GC and eating up CPU?

[kk]

Hi all,

In looking at some performance issues for a game I'm developing I came
across some interesting facts.
Although I've minimised GC caused by my app, other apps can still
cause one.
Also, during framerate drops in my game, I've noticed things like the
weather service, email checked, etc.
going nuts in the background. (This is on Android 1.6).

I don't really want to block incoming calls, i.e. go into flight mode,
before the game starts.
I think it's important for the game to be interrupted if there's an
incoming call.
However, while playing, I don't think people care about weather
updates, email updates, texts, etc.

Is there an interface that will let me control what is "active" in the
background and what should be "suspended"?

cheers,
kk.

George,

Is it meant to alloc every time you call it then?
That's going to cause GC to collect at random times during my game :(

[android-developers] ServerManagedPolicy not working as expected - getting many "This app is not licensed" responses.

[kk]

Hi all,

I've implemented the ServerManagedPolicy based on the sample in the
LVL libs.
My understanding was that it's much more flexible comparing to the
StringPolicy in the it  caches responses and it
doesn't always need to check.

In my dev panel I have the settings for my app returning LICENSED all
the time. This works quite a few of the times
but when I don't have signal (e.g. when I'm on the tube/underground) I
get:

com.android.vending.AsynchRequestRunner$1.runRequestRetrying
Failure(): Got IOException from async request: Host is unresolved:
android.clients.google.com:80

Am I missing something? Do I need to tweak any settings regarding the
caching?
I'm playing the game - all is fine. 5 minutes later I'm somewhere
without a signal and I get the "App is not licensed" dialog.
How soon does the caching "expire"?

cheers,
kk.

[android-developers] Rendering 24 bit RGB using Android Bitmap

[KK]

Hi,

  Is there anyway I can render a 24 bit RGB using Android Bitmap
class? The Bitmap.Config does not seem to have a 24 bit option. Is
there anyway to do this?

Thanks in advance

[android-developers] MediaPlayer showstopper bug - please help

[kk]

Hi all,

I'm having some trouble streaming a looping background track for my
game using MediaPlayer.

I have a bunch of short mp3s in /res/raw that I use as SFX and I play
using SoundPool.
The SFX playback all works fine...I'm mentioning it because it's
relevant as you'll see below.

The background music track (also an mp3) lives in /assets. The code I
use to play this track is at the bottom
of this post. Here's what happens:

Instead of the track looping, once it has finished playing, it starts
playing all the SFX from /res/raw in sequence!
Then, once all these have finished playing it starts all over again,
i.e. playing the background music track
and then all the SFX in the same order.

As if that wasn't weird enough, the behaviour described above only
happens in the emulator.
When tested on an HTC Tattoo and an HTC Desire it only does the above
once. I.e. it plays the background music
track, then all the SFX, and then it stops...it doesn't loop.

Any help greatly appreciated since nobody here has any idea what's
going wrong or how to fix it!

This is developed using:
SDK 1.6 API4 revision 3
SDK Tools revision 6

The code I use for the media player playback:

=
// note: p_theSurfaceView below is my class that extends SurfaceView
implements SurfaceHolder.Callback
MediaPlayer m_mediaPlayer = new MediaPlayer();
FileInputStream l_fis;
try
{
l_fis =
p_theSurfaceView.getContext().getAssets().openFd("bgmusic.mp3").createInputStream();
m_mediaPlayer.setDataSource(l_fis.getFD());
// from the docs: It is the caller's responsibility to close the
file descriptor.
// from the docs: It is safe to do so as soon as the setDataSource
call returns.
l_fis.close();

m_mediaPlayer.prepare();

m_mediaPlayer.setLooping(true);
m_mediaPlayer.setOnErrorListener(
new MediaPlayer.OnErrorListener() {
public boolean onError(MediaPlayer p_mp, int p_what,
int p_extra)
{
Log.e("m_mediaPlayer", "ERROR: MediaPlayer: (" +
p_what +") with extra (" + p_extra +")" );
return false;
}
});

m_mediaPlayer.start();
}
catch (IllegalArgumentException e)
{
e.printStackTrace();
m_mediaPlayer = null;
return false;
}
catch (IllegalStateException e)
{
e.printStackTrace();
m_mediaPlayer = null;
return false;
}
catch (IOException e)
{
e.printStackTrace();
m_mediaPlayer = null;
return false;
}

return true;
=

cheers,
kk.

[android-developers] Re: MediaPlayer showstopper bug - please help

[kk]

Thanks for the feedback Jason. Switching to OGG definitely fixed my
issue.
The other thing I noticed is that the setLooping call to MediaPlayer
has no effect at all.
If you want looping you just set the metadata tag ANDROID_LOOP=true.

For SFX I'm using SoundPool, which seems to be doing the trick.
Thanks again for the response.

cheers,
kk.

[android-developers] Problem opening page with javascript pop ups in webview

[KK]

I am very new to both android webkit and javascript. I have a web page
with 3 links (say A,B,C). When I open that page on my PC
browser(Chrome), and click on the links, A opens in the same browser
window whereas B and C pops up a new window. In my application I am
loading the original URL in a WebView. I have implemented my
WebViewClient and overridden the shouldOverrideUrlLoading. I am
getting the call to shouldOverrideUrlLoading whenever I click on A,
but not getting it when I click on B or C? Can someone help me as to
why this is happeneing?

Thanks
KK

I went through the page source and it looks like the 2 links that are

[android-developers] stopping the GC from kicking in

[kk]

Hi all,

When the GC kicks in during my game I sometimes get a noticeable
framerate drop, which is to be expected.

In logcat I get the usual:
   D/dalvikvm(   85): GC freed 55745 objects / 3149712 bytes in 709ms

Is there any way to get more info as to what is causing this?
I.e. what in my code is causing the GC to kick in...

cheers,
kk.

Can't get Froyo (Android SDK 2.2 release) APN emulator proxy settings

[android-developers] GLSurfaceView onPause blocked in Froyo

[KK]

I am using OpenGL to do some rendering and whenever my rendering gets
paused I call onPause of GLSurfaceView and later when I resume
onResume of GLSurfaceView. This was working fine till I upgraded my
Nexus One to Froyo today. After that the thread calling onPause seems
to be blocked in that API. Anyone has any idea why this is happening?
Is there anything I need to change for this to work on Froyo?

[android-developers] Re: GLSurfaceView onPause blocked in Froyo

[KK]

I am calling it because the documentation tells so.

public void onPause ()

Since: API Level 3
Inform the view that the activity is paused. The owner of this view
must call this method when the activity is paused. Calling this method
will pause the rendering thread. Must not be called before a renderer
has been set.


If i don't call this the OpenGL rendering thread will keep on giving
the onDrawFrame calls.

regards
KK
