[android-developers] Any way to find out the current running activity from a service?

[Paul Drummond]

Hi,

I have been looking for this for a while but I can't find any way of doing
it.  A contrived example would be a service that simply displays the name of
the current running activity as an Ongoing Notification.  For instance, when
the user is reading a particular email, the name of the activity (hopefully
the email title!) would appear in the notifications window and when the user
switches to read a text message, the notification would change to show the
name of the new activity.

Is there a way to do this in Android?

Thank you,
Paul Drummond

[android-developers] Re: listactivity problems

[Carl]

Great! That works.

I would like to show a textview at the top of the list (saying
something like "Select the item"). I followed an example, but I can
only see it say "No data".
I have changed my code by adding setContentView(R.layout.mylistact),
and this is what mylistact.xml looks like:


http://schemas.android.com/apk/res/
android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingLeft="8dp"
android:paddingRight="8dp">







 


Any ideas?

[android-developers] AutoCompleteTextView with SimpleAdapter

[kostmo]

Hello,
I am trying to use a SimpleAdapter to populate my
AutoCompleteTextView.  I observe that the Filter runs after the third
keystroke as specified in my layout, and "suggestion_list" is being
populated with at least five elements.  After the filter runs, the
completionHint drops down from the AutoCompleteTextView, but the there
are no rows underneath (which should contain suggestions).

The underlying datastore is an ArrayList of HashMaps.  The HashMap key
to the value desired in the suggestion rows is "vernacular_name".
Since I have specified this in the super() SimpleAdapter constructor,
I assume that it should be calling setViewText with the correct
arguments behind the scenes.

Can anyone see what is wrong with this code, and why the Views
corresponding to suggestions are absent from the AutoCompleteTextView
dropdown?

Thanks,
Karl

public class VernacularAutoComplete extends Activity {

final static String TAG = "VernacularAutoComplete";
ArrayList> suggestion_list = new
ArrayList>();

@Override
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);

this.setContentView(R.layout.autocomplete);
SuggestionListAdapter autocomplete_adapter = new
SuggestionListAdapter(
this);

AutoCompleteTextView textView = (AutoCompleteTextView) 
findViewById
(R.id.userText);
textView.setAdapter(autocomplete_adapter);
}

// XXX compiler bug in javac 1.5.0_07-164, we need to implement
Filterable
// to make compilation work
public class SuggestionListAdapter extends SimpleAdapter implements
Filterable {

VernacularFilter vernacular_filter = new VernacularFilter();

public SuggestionListAdapter(Context context) {

super(context, suggestion_list,
android.R.layout.simple_list_item_1,
new String[] { "vernacular_name" },
new int[] { android.R.id.text1 });
}

class VernacularFilter extends Filter {

@Override
protected FilterResults performFiltering(CharSequence 
constraint) {

FilterResults f = new FilterResults();
if (constraint != null) {
// Log.d(TAG, "Running filter...");

ItisMirrorResponseParser imrp = new 
ItisMirrorResponseParser(
(String) constraint);
ArrayList> 
filter_result = imrp
.parse();

f.values = filter_result;
f.count = filter_result.size();
}
return f;
}

@Override
protected void publishResults(CharSequence constraint,
FilterResults results) {

VernacularAutoComplete.this.suggestion_list =
(ArrayList>) results.values;

SuggestionListAdapter.this.notifyDataSetChanged();
}
}

@Override
public Filter getFilter() {
return vernacular_filter;
}
}

What that button does is remove all of the files YOUR application has put
into the cache directory.  Your code looks okay, though you should probably
make it recursive to take care of sub-directories.

Hi,

Is there any library already available for speech signal re-sampling?
I have sample speech input with the following config.

8Khz, 16bit PCM.

I wish to resample to rates like 11.25, 22.5, 44.1khz, 16khz etc.

Is there any open source project doing this?

[android-developers] Spinner - don't display selection

[droidin.net]

I'm trying to use Spinner as a button with selection pop-up. Basically
I want an icon and when user clicks it - the popup list is displayed
and user can make a selection.
The Spinner happily accepts icon image as drawable background.
Unfortunately when I select a value the text overlays the background.
Is it possible to set selection text color as a transparent? Or maybe
there's a better way?

Thanks,

Bo

Just a random side note, but you probably want to use Uri.encode() to

[android-developers] Re: ImageButton press feedback

[Jeff Sharkey]

The framework offers "stateful" drawables that automatically change
based on user interaction, such as focus or touch.  Here's an example
of the default Button background is defined:

http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob;f=core/res/res/drawable/btn_default.xml;hb=cupcake

When a drawable like this is set as a android:background or
android:src, the framework will handle swapping out the icon based on
state for you.  (You don't need to write onKeyDown, etc.)

to listen for the ACTION_DEVICE_STORAGE_LOW broadcast through a
.

This way, if the device runs low on space, you can help by
automatically purging your cache.

[android-developers] Re: HTTP and some extra

[Kausik Das]

While you are using HTTP Get, you have nothing to do with the HTTP
packet that is sent to the server. But while you are doing POST, then
the body part in the request is very important. If you've seen the
code, the problem is, say, I want to ready a file - do base64 encode -
send the packet to the server. Assume the file size is >= 5 MB. You'll
see the HTTP classes are not adequete to match this requirement or
even if it is I do not know.
But the problem is, like Windows Mobile/Blackberry - How can we know
the network services (DATA/VOICE/ DATA+VOICE/Emergency etc.) available
at the time of connection - I do not want to add a listner for that!
Is there any concept of Access Point in Android? What other network
parameters are very much Android specific those one should take care
of?

Sorry, this can only be done by a manifest declaration.  You can, however,
enable or disable the component declared in your manifest at runtime using
the PackageManager class.

[android-developers] adc2: can use third party lib from the market?

[blues]

My app uses the text-to-speech lib from the market, which is
developed
by Google Charles Chan. User needs to install the lib from the market
first time use my app (using market intent).

So is it eligible to have the app download the lib from the market?

And any technique difficulty here? for example, will the app be able
to download and use the lib from the market? any security limitation
here?

[android-developers] Re: 1.5_r3 backward compatibility

[Peter Jeffe]

Xavier and Diane, thanks for the confirmation on the SDK level, I was
hoping that was the case!

On Aug 3, 3:35 pm, Dianne Hackborn  wrote:

Yes, that works just fine, but it limits us to only being able to
publish an apk for that specific level and above--unless we want to
create an entirely different app for each supported OS level, which is
unreasonable for most apps.  Normally (say for PC or Unix software)
you would make different install packages available for different
combinations of OS and version, or perhaps have a single install
package that can handle a set of different OS versions.  But at the
moment we can't do that on Android, we can only specify a minimum
supported SDK level.

So what we really need to be able to do is publish, for the same
application, one or more apks, each with a minimum and maximum SDK
level.  If this was available today then I could still support users
still on 1.0 and 1.1, but I was forced to abandon them because I
wanted to have 1.5-specific features in my app.  That's not good user
support, and it's going to get much worse very soon as the Android
versions proliferate and we have quite a few different levels of OS
out there at any given time.  We developers need to be able to choose
which versions we support and we need to have the tools available to
do that.

Hope that makes sense.

[android-developers] Using Intent on default Google Map

[guna]

I launch the default google map apk from my application, by starting
the intent
new Intent(Intent.ACTION_VIEW, Uri.parse("geo:"+lon+","+lat)), 3);

What I want is to start the map with menu option "my location" clicked
and the current address displayed on the sign (user normally can bring
up the sign with its address with a long click on the map.)

There is a Google application called "places directory" which can
trigger a similar function on Google map, i.e. start the google map
with "my location" with a sign that says "You are here"
The source code for this application is not available, so I can't
check what intent it uses to trigger this action.

Any suggestions are welcome.
If possible tell me where i can get the source code for default google
maps... because i cant find out from git repository


Thanks,
Guna

[android-developers] Soft keyboard - full alpha-numeric, but defaulting to numbers

[Jason]

For cases where you know a user is likely to enter a number before
characters, is it possible to set an EditText View's soft keyboard/IME
default to the "numbers input" yet still retain all it's alpha-numeric
capabilities?

I can get the keyboard to automatically shift to the numbers input by
setting the
android:inputType="number", but then it prohibits characters.

[android-developers] Re: Eclipse 3.3, Android SDK 1.5, adb 1.0.18 running, 1.0.20 needed

[misbell]

Yes, I am. I only have one SDK downloaded onto OSX. As I said, I went
right into the directory (android-sdk_m5-rc15_mac-x86/tools) and
stopped and restarted adb. The SDK definitely comes with 1.0.18.

Let me check again visually right now...

Ok so I

a) downloaded the folder android-sdk_m5-rc15_mac-x86 from here:

http://developer.android.com/sdk/1.5_r3/index.html

b) here is my bash profile
echo $PATH
export PATH=${PATH}:/Users/Dev/android-sdk_m5-rc15_mac-x86/tools

c) installed ADT from here
https://dl-ssl.google.com/android/eclipse/

d) then went to Eclipse | Preferences and chose Android, pointed it at
SDK folder and instantly got two dialog boxes

1.  (!) Required minimum version of adb: 1.0.20 Current version is
1.0.18
2  (!) Error loading the SDK
   /Users/Dev/android-sdk_m5-rc15_mac-x86/platforms is missing

[android-developers] Re: Images not loading on the phone

[Jason]

Pulkit,

I had a similar problem. It seems that BitmapFactory silently fails
(returning null) when BufferedInputStream blocks while fetching from
the connection (I think). If the BufferedInputStream is coming from an
SD source, it works because it doesn't block (I think). The solution
for me was to download the entire stream as a byte array first, and
then call BitmapFactory.decodeByteArray(...)

To do that efficiently, I got the advice to read bytes from a
DataInputStream, filling up fixed sized chunks at a time until the
input stream is finished, and then copying the data from those chunks
into a final byte array (now that we know the full size of the
download). Here's some example code for this:

///
// example of using Bitmapfactory.decodeByteArray instead of
Bitmapfactory.decodeStream

public static Bitmap fetchImage(URL url, String userAgent) throws
IOException {
byte[] bitmapByteArray = JsonUtils.fetchUrlBytes(url,
userAgent );
Bitmap bm = BitmapFactory.decodeByteArray(bitmapByteArray, 0,
bitmapByteArray.length);
return bm;
}

///
// example of downloading a byte array in chunks

private static final int CHUNKSIZE = 8192;//size of fixed
chunks
private static final int BUFFERSIZE = 1024;   //size of
reading buffer

public static byte[] fetchUrlBytes(URL url, String userAgent )
throws IOException {

HttpURLConnection connection = null;

connection = ( HttpURLConnection ) url.openConnection();
if(userAgent != null) {
connection.setRequestProperty("User-Agent", userAgent);
}
connection.setConnectTimeout(5000);
connection.setReadTimeout(5000);

int bytesRead = 0;
byte[] buffer = new byte[BUFFERSIZE];   //initialize buffer
byte[] fixedChunk = new byte[CHUNKSIZE]; //initialize 1st
chunk
ArrayList BufferChunkList = new ArrayList(); //
List of chunk data
int spaceLeft = CHUNKSIZE;
int chunkIndex = 0;

DataInputStream in = new DataInputStream
( connection.getInputStream() );

while( ( bytesRead = in.read( buffer ) ) != -1 ) { //loop
until the DataInputStream is completed
if(bytesRead > spaceLeft) {
//copy to end of current chunk
System.arraycopy(buffer, 0, fixedChunk, chunkIndex,
spaceLeft);
BufferChunkList.add(fixedChunk);

//create a new chunk, and fill in the leftover
fixedChunk = new byte[CHUNKSIZE];
chunkIndex = bytesRead - spaceLeft;
System.arraycopy(buffer, spaceLeft, fixedChunk, 0,
chunkIndex);
} else {
//plenty of space, just copy it in
System.arraycopy(buffer, 0, fixedChunk, chunkIndex,
bytesRead);
chunkIndex = chunkIndex + bytesRead;
}
spaceLeft = CHUNKSIZE - chunkIndex;
}

if (in != null) {
in.close();
}

// copy it all into one big array
int responseSize = (BufferChunkList.size() * CHUNKSIZE) +
chunkIndex;

byte[] responseBody = new byte[responseSize];
int index = 0;
for(byte[] b : BufferChunkList) {
System.arraycopy(b, 0, responseBody, index, CHUNKSIZE);
index = index + CHUNKSIZE;
}

System.arraycopy(fixedChunk, 0, responseBody, index,
chunkIndex);

return responseBody;
}

Your HashMaps do not have anything named "label" or "description".
Change your HashMap keys to "label" and "description".

Are you sure that you are pointing ADT to the latest SDK?

[android-developers] Eclipse 3.3, Android SDK 1.5, adb 1.0.18 running, 1.0.20 needed

[misbell]

When you try to point Eclipse 3.3 to Android SDK 1.5 (latest build as
of today Aug 3 2009) I get an error saying that I have the wrong adb.

so I went to /tools and checked it out, running adb version.
Sure enough, 1.0.18. including after a restart.

Could I have vry specific directions for how to get this
to work (running on OSX). If I have to go get SDK source code, can I
know specifically where I have to go?

Thank you,

[android-developers] listactivity problems

[Carl]

I am trying to build a listactivity with listitems that consist of two
textviews. Unfortunately I don't see anything but lines in my list.
Can anyone tell me whats wrong with this code?


in list_item.xml


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

 

 


in my class:

public class mylv extends ListActivity
{
ArrayList> list = new
ArrayList>();

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);

// add items to the list
HashMap item1 = new
HashMap();
item1.put("line1", "one");
item1.put("line2", "two");
list.add(item1);
HashMap item2 = new HashMap();
item2.put("line3", "three");
item2.put("line4", "four");
list.add(item2);
HashMap item3 = new HashMap();
item3.put("line5", "five");
item3.put("line6", "six");
list.add(item3);

// build the list adapter
ListAdapter adapter = new SimpleAdapter(
this,
list,
R.layout.list_item,
new String[] { "label", "description" },
new int[] { R.id.text1, R.id.text2 }
);

// show the items
setListAdapter(adapter);
}
}

Off screen bitmap might be a possibility - let me look into that.

[android-developers] Canvas + Bitmap + ColorMatrixFilter is great. How to SAVE the bitmap?

[Jason Proctor]

the problem i think is that the filters and transforms and all that 
are done in native code, then that code writes to the frame buffer. 
getting that stuff back and turning it into a java Bitmap would be 
expensive.

can you draw into an offscreen bitmap somehow? ISTR something being 
possible along those lines.

Okay, I managed to get it to work on a real phone (Google Dev Phone

just use the geo command?

Possibly, it's because your service crashed:

> W/ActivityManager(  583): Scheduling restart of crashed service
> com.mypackage/.MyService in 5000ms

Usually, logcat will show a stack trace associated with service crashes.

Bear in mind, though, that your process will be shut down for other
reasons as well, such as memory reclamation. Keeping a service running
all the time is an Android "code smell" -- while it is possible, and
there are occasions when it is the right design, it feels like the vast
majority of people try it when they don't need it.

Consider using an AlarmManager to start your service on a periodic
basis, and have the service stopSelf() when the background thread is
done performing that cycle's worth of work. This will be more reliable
and, for reasonably long alarm periods, more efficient.

[android-developers] Activity timeout on WebView load

[droidin.net]

In my app I have to load external page into WebView-based activity.
Some of my users with slower connections are reporting screen timeout
while waiting for the page to load. What would be a good way of
loading the page on backgorund thread and then refreshing the screen?
Use HttpClient to fetch it and then use WebView#loadData? My fear is -
the page I'm loading is pretty complicated there's some JS that
happens on load - wouldn't I just mess it up? Is there an alternative
way of doing what I need?

Thanks,

Bo

[android-developers] GsmCellLocaion.getCid frequently returns -1

[Richard Schilling]

I know that a -1 value from a call to GsmCellLocaion.getCid means that
the network is unknown.  But, I'm frequently getting that as a result
even though the phone is connected to the network and able to send/
receive calls.

Can anyone shed some light on why this happens and how to get around
it?  From what I can tell, GsmCellLocation.getCid() is the only API
call to get the tower id that the phone is connected to.

Thanks in advance.

Actually, Market should have been supporting android:minSdkVersion for a
while, since that was done way back for 1.5.  Is it not working?

[android-developers] Re: Launching a Service at the startup

[R Ravichandran]

Thanks Mark. Actually the code I posted missed out the 'onStart' method
details that I actually tried. Here is the actual 'onStart' method of the
MyService class I used where I create the thread and starting it.


@Override
public void onStart(Intent intent, int startId) {
System.out.println ("MyService  ))");
super.onStart(intent, startId);
Thread t = new Thread(this);
t.start();
}

I modified the run method I put some System.out. statement inside a
while(true) loop. The idea was to keep this service running as long as the
device is on. But it looks like the system is sending a SIG 9 to kill the
process (process id 697) for the 'service'. Here is the logcat lines that I
see.

D/installd(  557): DexInv: --- BEGIN '/data/app/vmdl51510.tmp' ---

[android-developers] Re: Rotate TextView to an angle... What's wrong with this code?

[Moto]

Thanks Jeff! It worked but by overriding the onDraw call not the
dispatchDraw.

@Override
onDraw(Canvas canvas) {
canvas.save();
canvas.rotate(45);
super.onDraw(canvas);
canvas.restore();
}

I tried the same method on an ImageView extended class but I didn't
get the same rotation, nothing happend than... any ideas?
canvas contains all that the user can see right?  So if it was a
LinearLayout the canvas will be what ever is contained inside it?
Sorry I 'm very new to graphics :P

Delete R.java from your src/ and let Eclipse pick up the one from

[android-developers] installing gphone drivers automatically

[jonathan]

I wish to create an installer that unpack the driver files so windows
new hardware wizard will automatically find it instead of have to let
user select where the files are.  I unpacked the driver files into
windows\system32, windows\ and windows\inf and windows
\system32\drivers,  then the wizard found the inf file, recognized it
as HTC Dream Composite ADB Interface, then it said "Please insert the
compact disc labeled 'ADB Interface Installation Disk' to your CD ROM
drive.
am I doing something wrong?

If there were API changes then the API level would have changed. All
"Android 1.5" platforms in the 1.5 r1 to r3 SDKs show as API 3.

The update of the SDK to r2 and r3 are only for security fixes in the
emulator system image. See the original post on these mailing list for
details.

Are you sure forcing portrait mode for configuration activity could

I've tried to add: android:screenOrientation="portrait" to my activity
and the problem is still here.
The activity is displayed in portrait whatever the orientation but the
phantom widget bug is still here.

At some point it will, though I don't know when that will be.  This is what
android:minSdkVersion was introduced in Cupcake for.

I suspect the answer, at least in the short term, looks like this:

http://android-developers.blogspot.com/2009/04/backward-compatibility-for-android.html

That being said, this is also another fine area for competing markets to
out-do the Android Market: offer N app flavors for different
firmware/hardware, yet roll them all up for the purposes of popularity,
ratings, etc.

[android-developers] arcade style virtual joystick

[Croco]

Hi All,

I'm wondering if someone know a snippet of code that would implement a
joystick behavior.

I did a 4 orientation button widget but it's really not user friendly
for my game :(

Thanks by advance.

Thanks Romain, can you confirm that there were no API changes between
1.5r1 and 1.5r3?

And Fred, there is definitely no way you can expect a given level of
firmware to be universally used.  We're still getting users on 1.1
(well, not since we recently required 1.5 :-), and then you've got
custom builds, dev builds...

So that's why I'm really hoping that Google will allow developers to
publish multiple builds for different OS versions in the future.  It
was very tough to have to hold off releasing 1.5-specific features
until a critical mass of users were upgraded to 1.5.  At this point
there's no turning back on increasing platform divergence, and the
Market has to allow for us to publish builds for each release we
choose to support.  Romain, do you know if this is in the plans?

[android-developers] Re: Serious dx error. Desperately need expert advice.

[Dan Bornstein]

First of all, thanks for taking the time to investigate, and I'm glad
you've found a workaround for this.

As a bit of background, the original version of the code that collects
local variable debugging info was written to target an inefficient
output representation. The output format was fixed before 1.0 shipped,
but the "middle end" of the local variable code wasn't fully updated.
As a result, we found (later) that there were many cases where
redundant local variable info was emitted. That problem was addressed
in Cupcake, but it turns out that the fix wasn't without bugs of its
own.

I just tried reproducing the issue with the version of dx in Donut and
the one in Eclair. The Donut version still has the bug, but it has in
fact already been fixed in Eclair. I suspect it is the same as issue
#2868, .
Unfortunately the master (aka Eclair) branch hasn't been pushed to the
open since the fix was made, but I believe doing so is currently on
the short list of things to do for the folks who do that sort of
thing.

BTW, you can blame me directly, for the most part, for bugs in dx.

Most likely, they arrange to handle the rotation themselves.

http://wiki.andmob.org/samplecode

Look in there for the links to the Rotational Forces series of blog
posts. This one covers what you need:

http://androidguys.com/?p=2723

In your case, you would detect the rotation and change how you draw on
your canvas to match.

Hi AV, I'm not sure what you are trying to do, but I recommend

[android-developers] Keeping graphics running through orientation change

[SChaser]

How does one create a graphics canvas that is visible by the user
through orientation (port->land->port) changes? If one defines layout
land and port, there is a noticeable pause during the switch. Yet, I
downloaded a bubble level application that never pauses as orientation
changes - even when it switches from a circular level (gravity vector
through back of device) to a flat level (gravity vector through side
or bottom edge). How is this done?

[android-developers] Sending an email

[Mark Wyszomierski]

Hi,

I'm looking to send an email, I see we have a few options:

1) Start an intent to send the message, this will popup an activity
the user has to interact with to fire the message off.

2) Include the javamail jar in my project, ask the user for their smtp
info one-time, after that I can automatically send messages.

I need to be able to automatically send messages, so #1 is out. I
could go with #2, but it requires usage of an external jar. Is there
not some method in the android library which can already do this? I'd
like to avoid additional jars if possible,

Thanks

[android-developers] Accessing logs on Android

[Jay-andro]

Is there a way to access the default logs on the phone for purposes of
uploading for debugging purposes?

I'd like to be able to provide an "Upload Logs" button that allows the
users of my app to upload their logs if they are encountering issues
with the app. I know I can write my logs to my own file and provide an
upload for that, but I like the context provided by the system logs
interspersed with my log entries to understand what else is going on
on the device when my app has issues.

Is app access to the system logs considered a security issue and hence
not exposed or is there a way to get at the system logs
programmatically? By system logs, I'm referring to what one can see
using DDMS.

thanks
Jay

[android-developers] Launch an app from within the native Contacts app

[Jay-andro]

I would like to be able to launch my app using a URI scheme rather
than an StartIntent. The idea is to be able to embed this "link" in
other apps for example inside a Contact as a URL. clicking on the URL
from within the contact should open my app. Is this possible?

On iPhone, an app can declare a "scheme" for itself in a plist file,
and when any link that starts with "scheme://" is clicked anywhere on
the phone, this will be translated by the OS as a launch request for
this app. Anything similar on Android?

Thanks

[android-developers] Adding a hand-crafted WAV to the ContentResolver database

[Rhodri]

Hello there,

I've got some code that generates 16-bit PCM audio, and have written a
method to encase it in a valid WAV header - but when I try to add such
a file to the ContentResolver's database (with getContentResolver
().insert()) I get a rather unhelpful CONSTRAINT FAILED error. Is
there a specific MIME type I should be using, since audio/x-wav
doesn't work. I've tried just saving the file to the root of the SD
card, but to get it to show up in the system's audio picker I have to
restart the device.

Any advice?
Thanks,

[android-developers] Activity objects in memory after onDestroy.

[Felipe Silveira]

Hi everyone,

I have a activity MyActivity, which "kills" yourself using the finish
() method.

The problem is: after the kill operation, method onDestroy is called,
but the object of type MyActivity is never garbage-collected (I forced
the GC run). It is causing a memory leak, because MyActivity is
launched many times, by other activities.

Does anyone know when the Activity object is supposed to be garbage-
collected, and what can be done to avoid the issue I mentioned?

Thanks in advance.

[android-developers] How to hide dialer application after establishing call?

[mmj]

Hi all,

I am with an application that will establish a call from it and do
something else after that.Establishing call from my application is
working fine using Intent.Action_Call.But after that the control is
going to the native dialer application.I want to bring the control
back to my application after few seconds.Even though i start a new
activity depending on the call states obtained by the
PhoneStatelistener, it is launching the new activity in that
application.But it is all happening at the background because as soon
as dialer comes into picture,my application is minimized.

I need the control to be back to my application from the dialer after
some time and call established should be there until the user is
disconnecting it.

Can anyone help me in implementing the same?

Thanks in advance

[android-developers] plan about video on download(VOD) framework

[ZhangJieJing]

Hello  Everyone,

I'm a developer of android product, I'm working for the online play without
broswer, like some P2P stream player on our device, I heard someone said
that Google's Android Team have some play on that, I want to know is this
true?  or I must make a framework to P2P stream video play.


BTW,
Can anyone give some suggestion about how to share memory with the player
application.
The Normal P2P interface is like p2p_read_request(int fd, char *buf, size_t
request_size, time_t block_time);
fd: this is just the id of cache, maybe some is the file descriptor.
buf: is requesting bufer pointer. the download lib will full fill this
memory.
request_size: is the size of request. the player can get this memory and
play, in some all-in-one player.
block_time, this is the longest time will waiting.

since we have multi p2p download lib from different vendor, so I start a
server to handle all of this.
But I can't find a good way to share memory to the player (they are in
different process).
the cache is controled by download lib.


Thanks.

Best regards,
Zhang Jiejing

[android-developers] Recording/Playback volume control

[Venkatesh D]

Hi all,

I am developing an application which involves recording and playback
of audio. Am using MediaPlayer to record the audio from Mic in amr
format, save it to a file and playback the same file. I wish to have
the best audio record/playback performance with maximum recording
volume and same while playback.

Is there any API through which I can increase the recording or
playback volume?
