[android-developers] MediaPlayer sound problem

[BlackLight]

Hello.

I have this task:
Need to play short (0.3-0.4 sec) sounds all the time. When sound is
played, it should start again, etc. User can press button to reset
sound - it should stop and lunch.

I did many tests. I tried to create 1 MediaPlayer, then do this:
MediaPlayer.OnCompletionListener complListener = new
MediaPlayer.OnCompletionListener()
{
public void onCompletion(MediaPlayer mp) {
lunchSound(); // "rewind"
}
};

private boolean lunchSound()
{
try
{
mplayer.seekTo(0); // move to start
mplayer.start();
return true;
}catch(Exception e){}
return false;
}
When user press button, I call lunchSound();

It works great on emulator and on device if I have eclipse+debugger
on.
When I disconnect debugger, I have very strange errors - sound can
stop at all (till program restart), sound can start "repeating" (play
0.1-0.2 sec, then restart). Can someone please provide me some info
about problem?
Thanks.

[android-developers] Re: Audio streaming/progressive download over HTTP

[tainy]

what is more:

according to "media-formats.html" in the reference, MPEG4 SP is not
supported for both encoding and decoding,
so how can it support streaming?
quite confusing.

[android-developers] Re: How to browse deeper into /data/data/package/app_/

[brian.schimmel]

Hi,

I think I found two answers to my own question:

1. The files and directories I wanted to see start with a dot (.)
which are hidden by default on linux. Using adb shell, I can use "ls -
a" to see them. Anyway, I can not see them in DDMS and I cannot find a
setting to change that. I think I will file a bug report for that.
2. I've managed to write a simple directory browser activity in 67
lines of code. Only this way I found out that the files started with a
dot. I anyone's interested, I can post that code, too.

[android-developers] changing language on demand?

[DaRolla]

hello,

I need to change the language of a running apk on demand.

So the texts are set in xml to @strings/name

And there are different strings.xml inside values-de values-en values-
tr and so on.

Is there a way to tell android to update the layout in order to change
the strings automatically?

Or do I have to replace all of them by hand using findById().setText
(R.strings.name) ?

Greetings
DaRolla

[android-developers] Regarding RSS Feeds

Hi,

I want to display RSS feeds in my app.

I found that there are some RSS readers are available for Android.

I got some where the link: http://code.google.com/p/android-rss/source/checkout

It is not working on my sdk, giving some errors.

I think, it works on older versioned Android SDK.

Currently I am using android-sdk-windows-1.0_r2.

Can any one please suggest me the better one.

Thanks,
Manoj.

[android-developers] Re: changing language on demand?

[Marco Schmitz]

hi,

thanks for this.

I've found the same sourcecode here:
http://almondmendoza.com/2009/01/28/force-localize-an-application-on-android/

:)

All I had to add was this: this.setContentView(R.layout.main);

This way my layout is updated with the right language.

Thought there might be an update mechanism except loading the xml again

[android-developers] Parsing XML feed with SAX

[mobilek...@googlemail.com]

Hi,

I'm unable to consume a WS with the SAX, for some reason my
implementation doesn't read the complete XML feed, it reads it up to a
random point. Has anyone faced anything similiar? Here's what I'm
doing:

After calling a RESTful WS a read the response from the server as
follows:

if (isSessionActive){
  HttpEntity entity = response.getEntity();
  SAXParserFactory spFactory = SAXParserFactory.newInstance();
  SAXParser saxParser = spFactory.newSAXParser();
  XMLReader xmlReader = saxParser.getXMLReader();
  eventsHandler = new EventsHandler();
  xmlReader.setContentHandler(eventsHandler);
  xmlReader.parse(new InputSource(entity.getContent()));
}

Where my EventsHandler.java is as follows:

public class EventsHandler extends DefaultHandler {
@Override
public void startDocument() throws SAXException {
}
@Override
public void endDocument() throws SAXException {
}
@Override
public void startElement(String namespaceURI, String localName,
String qName, Attributes atts) throws SAXException {
Log.i(this.toString(), "<" + localName + ">");
}
@Override
public void endElement(String namespaceURI, String localName, String
qName) throws SAXException{
Log.i(this.toString(), "");
}
@Override
public void characters(char ch[], int start, int length){
}
}

Hope to get some feedback! Thanks.

[android-developers] Re: why there's no boot.img in Android-1.5

[david 1]

The kernel is lost. I traced the making log, and found boot image is
generated based on ramdisk image & kernel. So, boot image is not created
successfully. Then I 'make ARCH=arm CROSS_COMPILE=arm-eabi-
goldfish_defconfig & make'  and got a zImage. Then I used it as 'kernel' to
generate a boot.img and flashed it to G1. Finally, the G1 can not boot up at
all. I miss something else? Or zImage can't be used as a kernel for G1 at
all?  Any hint is appreciated.

[android-developers] Re: PendingIntent problem

[Fuzzmonkey]

Hello,

By explicit component do you mean  in the intent filter or code in the broadcast receiver? Is that
all i'd need?

Thanks,

George

I do not believe anything built into Android plays animated GIFs.

OutputStream outstream;
Bitmap bitmap = Media.getBitmap(getContentResolver(), selectedImage);

outstream = getContentResolver().openOutputStream(Uri.parse

[android-developers] Re: PendingIntent problem

[Fuzzmonkey]

I've added the scheme to my intent filter as following.

proxBroadcastReceiver = new MyIntentReceiver();
proxIntentFilter = new IntentFilter
("android.intent.action.PROXIMITY_ALERT");
proxIntentFilter.addDataScheme("custom");
registerReceiver(proxBroadcastReceiver, proxIntentFilter);

I'm now receiving the intents in my receiver again, but the intents
are still containing incorrect data. For example, here are three
proximity alerts i've added to the location manager. The numbers
before the alert info is the goal and sub goal number. These three
belong to goal 2, and are sub goals 0 - 2. If i add them in order,
that is (0, 1, 2) when the proximity alert is fired, i get goal 2, sub
goal 2 in the extras for my intent. My actual location is 2 0, and the
distance between each gps co-ordinate is relatively large. If i enter
the alerts in the manner shown below, i get the correct information,
that is, 2 0. Im assuming this is something to do with the intent /
pendingintent but can't figure out what the problem is! I just hope
it's note the location manager being massively inaccurate!

[android-developers] Netbook with Android

[info+farm]

Hello all,

I am an Android developer and I am going to buy a new netbook for
seamless portability.

Once I read it is possible to install Android on netbooks as an OS, my
eyes started to shine. Therefore, I would like to be able to test my
or third party applications on this netbook in the future.

Which netbook brand/model will be the best suited(no driver headaches-
sdcard, camera...) for upcoming Android OS for netbooks? I am reading
a lot of rumors on the net, but I cannot find a baseline.

Any idea will be appreciated...

Regards,
info+farm

Hello Mark Murphy

For showing direction between two points on map
there is for launching maps for driving direction
"this.startActivity(new Intent(Intent.ACTION_VIEW,
Uri.parse("http://maps.google.com/maps?

[android-developers] How to load content in WebView asynchronously

Hi

I use WebView::loadData to display something. But sometimes the data
may be very big, say, more than 200K.

I hope the WebView can display the content asynchronously to improve
the UI response.

Any one knows about this?

[android-developers] How to build a debuggable crosstool chain for android on linux_X86_64?

[Hucheng Zhou]

Hi @ll:
  I've successfully build the crosstool chain for android on host
linux_x86_64 (gcc-4.4.0, binutils-2.19, new-lib-1.17.0, gdb-6.6, etc), but
the problem is that the installed gcc cannot find the corresponding header
files, even for simple stdio.h. Why? I use the tar-ball
of android-toolchain-20081019.
  Another issue is how to build a debuggable cross gcc? Just set CFLAGS and
CXXFLAGS="-g3 -O0 -gdwarf-2"? I want to do some development on gcc.
  Thanks in advance.

[android-developers] Re: PendingIntent problem

[android-developers] Re: Screen lock turns of the accelerometer.

[dilit]

Accelerometer does work under screen lock when the power is not
dimmed.
We debugged it in ddms on the real g1 device.

Guess, if you can acquire a Power wake Lock, you should be able to
read acceleration.
We have not tried to acquire it in program, just manually.

This was done on current android version, not cupcake release.

[android-developers] Re: Parsing XML feed with SAX

[mobilekid]

It isn't big at all, it's got about 25 elements, it's not not a very
deep tree either. I've parsed way longer XML feeds in the past with
the same implementation of SAX.

I asked the server guy to remove the element where it got stuck, and
then it managed to parse one more element down the tree, and got stuck
again. So that makes me think the problem is to do with the size of
the document, but it isn't big at all... Any ideas?

[android-developers] Re: Parsing XML feed with SAX

[Mariano Kamp]

What happens when you add a println statement before the last line? Is this
reached? Is startDocument() called and how do you know that endDocument() is
not called? In the quoted code you're not doing anything.
Also, is it a conscious decision to use SAX here? I think SAX is a pain for
most ordinary cases, and when you have such a small document DOM might be ok
for you. It probably wouldn't here as the DOM parser uses SAX to build the
tree.

[android-developers] OnClickListener for a mapview never called

[RodgerWilko!]

Hi,

I have setup a OnClickListener for a mapview and find that it's never
called.  I have set clickable to be true but it's still not working.
Am I missing something or is the OnClickListener not supported on a
mapview?

Thanks

[android-developers] “The application xxxxxxxx (pr ocess xxxxxx) has stopped unexpectedly. Please try again.”

[Kenn Min Chong]

Hi there!
 For some reason I can't explain, when my app runs, I will on
occasion get the following error message:

“The application  (process xx) has stopped unexpectedly.
Please try again.”

When I debug my code, it seems to break at random places that doesn't
make sense. On top of that I tried to surround the entire code with a
try/catch block just to try to catch the exception, but it doesn't
work either. I'm suspecting it's the OS that is producing this error
message but I don't know why. As far as my code goes, if there were
exceptions caused by it, it would've been caught by the try/catch
block.  Can someone shed some light here?

[android-developers] distributing an app packaged with just emulator

[tansaku]

Hi All,

I was wondering if anyone has ever been able to distribute their app
in a bundle with an emulator?

The reason I want to do this is that I have some friends who don't
have android phones, but I'd like them to be able to play with my app
so that they can give me feedback.  I've previously sent them screen
casts, but I'd really like them to be able to get interactive with the
app.

Now I could ask them to get all installed with the whole android
framework, eclipse etc,. but some of them are not so technical.
Ideally what I'd like to be able to do is create a package that is the
android emulator with my app and perhaps 1 or 2 other related apps pre-
installed, so that they can download it, open it and run it
interactively on their computers?

Has anyone ever tried this?

So far I found that I can run the emulator standalone, and I assume I
could probably send them just that and it would run.  However the adb
tool is needed to install apps.  I could send them that too, and ask
the to run an 'adb install myapp.apk' from the command line, but at
the moment I can't even seem to do that myself.

Running the emulator standalone, the adb tool can't seem to see it:

samuel-josephs-computer-2:tools samueljoseph$ sudo ./adb devices
List of devices attached

I just get no list of devices ...

I have previously used the adb tool to install apk files, but that is
after I had started the emulator from eclipse - of course even then I
always have to restart eclipse and the emulator two or three times
before I can get the connection (I am on OSX 10.5.6., eclipse
3.4.1) ...

Any suggestions greatly appreciated.

CHEERS> SAM

[android-developers] Emulator data connection problem

[Farshad]

When I run the emulator on my laptop with wired connection, my rtsp
player application works fine.
But when I have the laptop hooked up with a wireless network, my rtsp
player application cannot establish data connection.
My rtsp player application always works fine on G1.

Why the emulator has problem with application making data connection
when the laptop is on wireless connection and works fine when laptop
is on wired connection?

[android-developers] Customer signature

[Stéphane POUVRASSEAU]

Hi !

In my app, I need a customer signature for prooving the customer have 
seen some informations and validate them.

- Does anybody knows the Android way for implementing a customer signature ?

With Windows CE, we can use a signature's specific component, and the 
customer can use the pen to draw lines. But how can we do this with 
finger's like mobile phone ?

It seems to be a very difficult question, and I haven't found an answer 
to my question yet.

Best regards,
Joe.

[android-developers] How to HTTP Post

[Moons]

Hello everyone,
I'm posting here because I searched the web and found nothing about
how to HTTP POST.
What I want to do is to access a webpage (PHP) sending data with the
POST method.
I'm not interested about seeing the webpage, I just want to send the
data.
Actually, it's for a game i developed, and users are asking for online
scores, so I wrote a PHP script that takes POST data and writes the
score in an SQL database.

Thanks for your help.

[android-developers] Information about required permissions

[thiagofj2000]

Hi all,

I would like to know if there's documentation about what are the
required permissions for each activity, intent, broadcastReceiver,
etc.

Or maybe there is a file with this info in the SDK?

Thanks

[android-developers] aidl problem in building android source code

[android-developers] Emulator power off immediately

[Chih-Wei]

Hello,
I just do repo sync and recompile the whole tree again.
When I start the emulator, it showed the android logo, and then
a window 'Power Off  shutting down' is shown.
Then the emulator window has no any response to any input. Strange...

I remember I can run the emulator correctly yesterday or the day
before yesterday.
I tried to point the system.img to an old one I backed up,
and the emulator runs fine.
So recent changes break it?

[android-developers] Android testing: Emulator vs G1

[HowlettAndroid]

Hello,

Hope you lot can help. I'm currently testing my application in
the SDK emulator, Great everything works perfectly. The next step was
to try the same application loaded on to the G1. After loading the
app, I'm getting some strange behaviour. Some Activities seem to be
called by intents multiple times, when in the emulator they only
appear once. Looking at the code I can't see what could be wrong. Any
help would be great.

Thanks

[android-developers] What's this problem?

[Alex]

I have written a method, like this
private Bitmap getBitmapFromUrl(String urlString)
{
  try  {
URL url = new URL(urlString);
HttpURLConnection con = (HttpURLConnection)url.openConnection();
InputStream is = con.getInputStream();
Bitmap bmp = BitmapFactory.decodeStream(is);
return bmp;
  }catch(Exception e)
  {
return null;
  }
};

When I call this method continuously in a thread, it returns a valid
bitmap only at the first call, as for the following call, LogCat would
report "jpeg error 20 Improper call to JPEG library in state".

Actually, I think the problem is because of the connection error,
since when I debug the application, the inputstream seems invalid.

Is there anyone know what the problem is it?
Thanks in advance.

[android-developers] HttpUrlConnection problem

[Mika]

Hi all,

I have a strange problem with HttpUrlConnection. I can send data (with
POST), but the receiving succeeds only every second time or after a
sufficiently long (< 5 min) pause between the sends. I basically start
a new thread where the initialization of the HttpUrlConnection,
writing/reading from output/input streams and closing the connection
is done. If I don't close the input and the output streams the sending
works correctly each time.

Any suggestions where's the problem? The same problem was discussed in
here
http://groups.google.com/group/android-developers/browse_thread/thread/bc5454ffc71f77dc/837c09f4f1f750b2?lnk=gst&q=getResponseCode#837c09f4f1f750b2
but no solution were found.

[android-developers] Re: OnClickListener for a mapview never called

[Arnaud Weber]

have you tried the OnTouch event?
I've not used mapView yet but a click is the action to touch and to
release... i think on a mapview the proper event to catch is more a touching
event than a clicking event.

[android-developers] Start native application from Java

[Anders]

Hi,

I have a native application that I would like to start from a Java
interface. Does anyone know of a good way of doing this?

I can start the application using adb, with no problems. I can also
start the application using Runtime.exec(), but that doesn't work so
well for me; I need the application to run outside of a Java Runtime
Process.
Any ideas?

Thanks,
Anders

Yes, startDocument() gets called, endDocument() doesn't, I know that
as I've logged it.

Yes, I've always thought SAX is somehow quicker. I guess I will just
switch to DOM for that WS. Thanks anyway!

[android-developers] Re: Start native application from Java

[Dianne Hackborn]

Hi, this technically isn't part of the SDK, so would be better asked on a
group like android-porting.  (Yes, there are Java calls to do this, but
native code in any form is not supported at this time.)

You can't do android UI in C.  The UI framework is written in Java.

[android-developers] Re: PendingIntent problem

[Dianne Hackborn]

No, I mean setting the explicit component to your broadcast receiver
component on the Intent class.  I strongly strongly recommend this for this
kind of situation where you want someone to deliver some specific thing to a
component in your app.  Please read the Intent java doc for more info.

So wait...  you are saying you just wrote a regular application in an .apk,
and you can do this?  You really shouldn't be able to do this.  I am almost
positive you can't.  So I really want to confirm what you are actually
doing.

It's basically working as intended.  If you really care about this, in
cupcake you can go in to manage applications, see the list of applications
with running processes, and force stop that one.

[android-developers] Re: PendingIntent problem

[Rob Franz]

So with all the input from this thread, what's the proper way to send x
number of pending intents that are unique?
I guess I'm doing it not 100% correctly (even though it seems to work for me
and the intents are spaced out enough not to interfere with each other).  I
was doing it
as setData((Uri.parse("custom://"+SystemClock.elapsedRealtime())).

[android-developers] Re: Could title bar of activity listen to click event?

[Dianne Hackborn]

Implement your own custom title bar.  You will need to make this taller than
the regular title bar anyway for a decent user experience (especially if you
want DOUBLE tap...), so just bit the bullet and do your own thing.

[android-developers] Re: “The application xxxxxxxx (process xxxxxx) has stopped unexpectedly. Please try again .”

[Arnaud Weber]

To try catch the whole code is not a good practice but... have you tried to
catch exception or throwable?

It is not necesserly the system that is bugging but your thread may
eventually be candidate to garbage collection if no reference is made to it
and your parent thread has closed.

Are you working in a thread? have you tied it's life cycle with its parent
context thread lifecycle ?

[android-developers] Re: SharedPreferences got deleted! - What could be the problem?

[bo]

I do SharedPreferences.Editor.commit() in couple of places. 1.
Immediately after setting the preference. 2. in Activity#onStop.
Nevertheless when I restart the app the preferences are gone. Any more
ideas? I do create prefs programmaticaly after harvesting these from
user (username/pwd)

[android-developers] Re: SharedPreferences got deleted! - What could be the problem?

[Mattaku Betsujin]

I found that the preferences XML will break very easily if you store some
Strings containing 'special' characters. I am not sure what exactly those
are, but when I stored things like

 putString("someurl", "http://xyz/?a=b&c=d";)

the preference file becomes empty next time I try to open it.

My solution is to quote all Strings that I put into the SharedPreferences.
After that my problems seems to go away.

I couldn't find a Base64 encoder in the Android API, so I wrote a
quick-and-dirty PrefQuote class:

http://code.google.com/p/nubi/source/browse/trunk/android/nubinews/src/com/nubinews/reader/PrefQuote.java

 putString("someurl", PrefQuote.quote("http://xyz/?a=b";))

Hope this helps

[android-developers] Re: AudioRecord can't get any notification when record/marker position updated

[Dave Sparks]

I suspect the problem is the interval you chose: 50 frames @ 8KHz is
6.25 msecs. Your app is not going to be able to handle a callback
every 6.25 msecs. Try something more reasonable like 50 msecs (400
frames) and see if that works.

[android-developers] Re: Audio streaming/progressive download over HTTP

[Dave Sparks]

I'm not sure which reference you a referring to, but MPEG4-SP decode
is supported.

Encoding implies streaming upload, but the subject of this thread is
download, not upload. If you are asking about RTSP upload streaming,
that is not supported in any format today.

[android-developers] android 1.5: How do we use the AudioTrack class?

[Moto]

I'm currently initiating the AudioTrack() for MODE_STREAM.

I load some bytes using the write() and I see that it is working but
once hit the play() call nothing happens... what is the matter? should
I do something else that is not obvious??  Any tips Google friends?

My settings:
streamType - STREAM_MUSIC
sampleRateInHz - 44100
channelConfig - CHANNEL_CONFIGURATION_STEREO
audioFormat - ENCODING_PCM_16BIT
bufferSizeInBytes - 256Kthe total size (in bytes) of the buffer where
audio data is read from for playback. mode - MODE_STREAM

thanks!
-Moto!

[android-developers] Re: android 1.5: How do we use the AudioTrack class?

[Moto]

I thought you could continuously write data into the AudioTrack as
long as the buffer size specified at the creation of the AudioTrack
was not exceeded...  and you can call play() as long as there was
enough data to start playback...

[android-developers] Re: PendingIntent problem

[Dianne Hackborn]

That said...  I would be -very- suspicious about the code you posted where
you are effectively creating random identities for your pending intents.  In
most of the places where one uses a pending intent, you give it to something
that holds on to it indefinitely, so you need to be able to recover the
previous pending intent so you can give it back to have it unregistered.
That is why the API works the way it does.  This API is really not intended
to generate tons of pending intents whose lifetime is not being managed.

[android-developers] Re: AppWidget issues

[Jeff Sharkey]

So just a heads up that we won't be able to fix the onDeleted() bug
for the 1.5 SDK.  Here is a quick workaround that you can patch
against your class that extends AppWidgetProvider to correctly catch
and handle the onDeleted() event.

@Override
public void onReceive(Context context, Intent intent) {
final String action = intent.getAction();
if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) {
final int appWidgetId = extras.getInt
(AppWidgetManager.EXTRA_APPWIDGET_ID,
AppWidgetManager.INVALID_APPWIDGET_ID);
if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) {
this.onDeleted(context, new int[] { appWidgetId });
}
} else {
super.onReceive(context, intent);
}
}

[android-developers] Re: PendingIntent problem

[Rob Franz]

I was hoping you forgot about that piece of code...I think I saw that
somewhere (someone else posted it somewhere so I may not be the only one
using it) when I was trying to figure out why i was trying to send multiple,
different pending intents, but the data was not changing - essentially I
think that everytime I thought I was creating a new one, I was actually only
changing the one that I had just submitted.

 No, I mean setting the explicit component to your broadcast receiver

 kind of situation where you want someone to deliver some specific thing to

[android-developers] Customer signature

[Joe]

Hi !

In my app, I need a customer signature for prooving the customer have 
seen some informations and validate them.

- Does anybody knows the Android way for implementing a customer 
signature ?

With Windows CE, we can use a signature's specific component, and the 
customer can use the pen to draw lines. But how can we do this with 
finger's like mobile phone ?

It seems to be a very difficult question, and I haven't found an answer 
to my question yet.

Best regards,
Joe.

[android-developers] bad sqlite performance

[skink]

i was quite surprised when dealing with android's sqlite
implementation.

suppose i have db with a table counting
moro or less 4 rows.

now i do query 'select field from table'.

no 'where' clause so result set should have
all rows.

and i was surprized that Cursor 'allocates'
probably all the rows since it takes ~10
secs to db.query() + cursor.moveToFirst()

afaik sqlite on PC makes working set
'virtual' doing hard job on demand when one
wants to fetch next rows (i did the same
with python 2.5 which has sqlite support
and couldn't measure time of select +
fetching first row since it was so fast)

is my assumption correct that Cursor allocates all the rows not doing
lazy allocates?

[android-developers] Re: Customer signature

[dan raaka]

There is no ready-to-use signature widget in android.
But writing one shouldn't be too hard.
Create a custom view, see fingerpaint example in the APIdemos, and when the
user is done, take a snapshot of the view (which contains the signature).
This would very similar to a checkout machine in the malls.

The View class in the cupcake has a new function (not sure if it is public)
Bitmap createSnapshot(Bitmap.Config quality, int backgroundColor)

[android-developers] SDK1.5 AudioRecord sample rate problem

[szabolcs]

I was trying to record sound using the MIC with the AudioRecord class:

mRecord = new AudioRecord(
MediaRecorder.AudioSource.MIC,
SAMPLE_RATE,
AudioFormat.CHANNEL_CONFIGURATION_DEFAULT,
AudioFormat.ENCODING_DEFAULT,
BUFFERSIZE
);

This call results in:

ERROR/AudioRecord(1120): Recording parameters are not supported:
sampleRate 11025, channelCount 1, format 1
ERROR/AudioRecord-JNI(1120): Error creating AudioRecord instance:
initialization check failed.
ERROR/AudioRecord-Java(1120): [ android.media.AudioRecord ] Error code
-20 when initializing native AudioRecord object.

whenever the SAMPLE_RATE is some value other than
AudioRecord::DEFAULT_SAMPLE_RATE (8000) declared in ./frameworks/base/
include/media/AudioRecord.h from GIT.
The documentation says 11025/22050/44100 should be ok too.

Am I missing something?

Thank you for your help,
