[android-developers] Re: Miracast?
i wonder if any mobile android device can sustain 2 hours of miracasting its screen on which a movie is played without draining its battery, because it involves mpeg/h264 decoding first, capturing screen shots at min 30fps, encoding the screen shots to h264 bitstreams, muxing the bitstreams in TS and p2p sending the TS packets via RTP. has anyone tried it? On Wednesday, November 7, 2012 8:59:30 AM UTC-8, Robert Hattan wrote: I would recommend Google better advertise Miracast capability with Android 4.2. It hasn't been explained very well to consumers and if existing hardware is upgraded to Android 4.2 will it support Miracast. Similar to listing phones on Android.com, it would be nice to see a list of Miracast supported TVs, etc. Even more exciting would be the ability to share an Android 4.2 phone with an Android tablet as a future feature. -- You received this message because you are subscribed to the Google Groups Android Developers group.

your closing statement ...i can stick into a handler ( using a handler since the thread cant touch the UI itself ) that brings that activity, tab to the front or selected. seems to me the answer. that is, put a handler in the realizing activity to periodically realize something has happened. then call TabHost.setCurrentTab() to automatize tab switching.

[android-developers] Re: How To Override the “Back ” button so it doesn’t Finish() my Activity?
it seems that overrriding onKeyDown() method of your activity and
returning with a true value perhaps may serve your need.
On Jun 29, 8:42 am, draf...@gmail.com draf...@gmail.com wrote:
I currently have an Activity that when it gets displayed a
Notification will also get displayed in the Notification bar.
This is so that when the User presses home and the Activity gets
pushed to the background they can get back to the Activity via the
Notification.
The problem arises when a User presses the back button, my Activity
gets destroyed but the Notification remains as I want the user to be
able to press back but still be able to get to the Activity via the
Notification. But when a USER tries this I get Null Pointers as its
trying to start a new activity rather than bringing back the old one.
So essentially I want the Back button to act the exact same as the
Home button and here is how I have tried so far:
---
@Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if
(Integer.parseInt(android.os.Build.VERSION.SDK) 5
keyCode == KeyEvent.KEYCODE_BACK
event.getRepeatCount() == 0) {
Log.d(CDA, onKeyDown Called);
onBackPressed();
}
return super.onKeyDown(keyCode, event);
}
public void onBackPressed() {
Log.d(CDA, onBackPressed Called);
Intent setIntent = new Intent(Intent.ACTION_MAIN);
setIntent.addCategory(Intent.CATEGORY_HOME);
setIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(setIntent);
return;
}
---
However the above code still seems to allow my Activity to be
destroyed, How can I stop my Activity from being destroyed when the
back button is pressed?

[android-developers] Re: SIP Stack
mike, i just saw this open defect with sipdroid/pbxes: http://code.google.com/p/sipdroid/issues/detail?id=158q=batterysort=-priority i wonder if this defect comes from a belief in TCP between sipdroid/ pbxes and a thought that TCP connections can persist longer with less overhead (thus use less battery power) than UDP.

Mike, you knew it :) what is your mobile service provider? the sentence IP address changes are probably pretty rare looks strange to a T-Moble user like me. at least i find my G1 ip frequently changes :( So I haven't actually tested this, and I disclaimed because I wasn't sure :) If you're getting lots of IP address changes regardless of what's happening at the 3gpp/l2 layer, you're probably not going to not have a very good experience with streaming media of any kind because once the IP address changes, the RTP stream is going to tank regardless of SIP, RTSP, Skype, etc. That's why you'd need to deal with it more directly like using IP handoffs using Mobile IP, etc. Handoffs could be done using SIP, but it would be ugly. Which probably means that somebody has proposed it and that the working group has taken it on :) AFAIK, mobile IP is still not deployed widely, even though we were working on it the handoff probelm almost 10 years ago... Part of the reason probably is because 3GPP's latency is really awful for real time conversations so there's still too high an energy barrier to actually deal with the truly difficult problem of dealing with handoffs when TDM still works just fine. Maybe 4G will get rid of all that bizarre leftovers from the ATM/bellhead days that 3G had to live with to get standardized. In any case as far as SIP registration goes, it should be relatively easy to camp on an event for when the IP address changes and quickly reregister inside the SIP stack. It wouldn't be surprising that most of the SIP stacks already have that feature. How bad this is on battery life is obviously dependent on how often IP addresses are actually changing, but you have the exact same problem with IM so at some level it's acceptable since people do use IM...

Again, if this is just server-client streaming this is yet another reason to avoid SIP and look at RTSP. SIP is a rendezvous protocol, and all rendezvous protocols are complicated, with lots of things to consider. AFAIK -- it's been a long time -- SIP registrations can be very long lasting. Unless something has actually changed -- like your IP address moved -- it shouldn't be a problem. I'm not entirely convinced that this is a huge issue anyway because the cellular guys are probably moving you around at L2 for the most part (again, it's been a long time since I've paid attention to the 3gpp guys), so IP address changes are probably pretty rare. I have no idea if anybody's been deploying mobile IP which would more directly solve this issue.

Just make sure you don't use any SDK methods that don't exist on earlier platforms without checking the user's local sdk version. A further tip: as one of the ways to check you aren't using API that won't work on 1.5, set your project properties to 1.5 and see if there are compile errors. Do this once in a while, and at least once before every release. If any methods come up that do not compile on 1.5, and you still want to use them, you'll need to use reflection to make them compile for 1.5. It's messy but it works.

[android-developers] Re: SIP Stack
mike, is it possible that the situation where ISP changes ip of your phone differs from the situation where you manually change ip of your phone ipconfig/renew? that is, is it possible that a phone cannot detect change of ip until next time when it tries to send something out? by the way, what is the java/android api you use to detect ip change? could you share a code example with me? thanks :) On May 10, 11:46 am, mike enervat...@gmail.com wrote: On 05/10/2010 11:24 AM, HeHe wrote: when i mentioned ...not be able to receive incoming calls.., i was not thinking about just server-client streaming. Mike, you knew it :) what is your mobile service provider? the sentence IP address changes are probably pretty rare looks strange to a T-Moble user like me. at least i find my G1 ip frequently changes :( So I haven't actually tested this, and I disclaimed because I wasn't sure :) If you're getting lots of IP address changes regardless of what's happening at the 3gpp/l2 layer, you're probably not going to not have a very good experience with streaming media of any kind because once the IP address changes, the RTP stream is going to tank regardless of SIP, RTSP, Skype, etc. That's why you'd need to deal with it more directly like using IP handoffs using Mobile IP, etc. Handoffs could be done using SIP, but it would be ugly. Which probably means that somebody has proposed it and that the working group has taken it on :) AFAIK, mobile IP is still not deployed widely, even though we were working on it the handoff probelm almost 10 years ago... Part of the reason probably is because 3GPP's latency is really awful for real time conversations so there's still too high an energy barrier to actually deal with the truly difficult problem of dealing with handoffs when TDM still works just fine. Maybe 4G will get rid of all that bizarre leftovers from the ATM/bellhead days that 3G had to live with to get standardized. In any case as far as SIP registration goes, it should be relatively easy to camp on an event for when the IP address changes and quickly reregister inside the SIP stack. It wouldn't be surprising that most of the SIP stacks already have that feature. How bad this is on battery life is obviously dependent on how often IP addresses are actually changing, but you have the exact same problem with IM so at some level it's acceptable since people do use IM...

[android-developers] Re: how to DEBUG build an APK?
Bob, thanks for reply. i am still still very very confusedthe link you gave me is a constant FLAG_DEBUGGABLE, indicating the application is manifested to be debuggable. but what i need is some info telling my apk that it was a debug or release built without changing the debuggable attribute in manifest each time between debug/release builds. i need it because in case i forget to change the debuggable attribute of my release built to false my apk can still behave correctly. in short, (1). i dont want to change the debuggable attribute in manifest between debug and release builds.

[android-developers] Re: how to DEBUG build an APK?
thanks. now i understand it. Config.DEBUG is for DEVICE and not for APK. i need some info to tell my apk which of map api key to use. here are the 2 cases: (1). build apk by selecting Eclipse Run Run As or Run Debug As menu option. in this case, the apk is a DEBUG built and is signed by Android Debug key. hence, the apk must use the map api key applied with the md5 checksum of Android Debug key. no matter on which of emulator or real handset the apk runs, it is a DEBUG built. (2). build apk by selcting Android Tools Export Signed Application menu option. in this case, the apk is a RELEASE built and is signed by my key. so the apk must use the map api key applied with the md5 checksum of my key. is there any way for my apk to programmatically know that it itself is a DEBUG or RELEASE built without changing manifest debuggable attribute so that my apk can choose the right map api key? or, my question can be: is there any way for my apk to know by which of DEBUG/RELEASE key it was signed?

[android-developers] Re: how to DEBUG build an APK?
Brill, thanks for comment. using your approach, do you run a DEBUG
build on a real device and still succeed in map api?
my apk has no problem telling itself if it is running on emulator or
not, because running on emulator an apk should always assume itself a
debug build. my release build has no problem running on real device
either.
AFAIK, the map api key that an apk should use is decided by the app
signing key used to sign the apk; it is not decided by which emulator/
device the apk runs on.
so, when a DEBUG build runs on my REAL phone, it fails map api key,
because there seems to me no way to tell build type of an apk, UNLESS
like Bob suggested i put some semi-auto attribute or metadata in my
code, and remember to remove it before formal RELEASE, or devise some
makefile to put/remove the metadata for me automatically.
OR, i should not run a debug build on a real device and hope map api
works...

actually i had the same issue with different Map keys for dev and

My solution was a little bit of code that checks to see if your
running in the emulator or not. It works for at least Android 2.1
update 1:
public static final boolean isEmulator() {
if (1.equals(System.getProperties()
.getProperty(ro.kernel.qemu, 0))) {
// Emulator
return true;
}
return false;
}
public static final String getGoogleMapsAPiKey() {
if (isEmulator()) {
return YOUDEVKEY;
}
return YOURPRODKEY;
}
I've actually deployed this to a device and it seems to work just
fine.

All you have to do is check for that one flag. That's it. You should be running in debug mode (i.e., debuggable=true) about 99% of the time.

[android-developers] how to DEBUG build an APK?
does anyone know how to DEBUG build an APK and launch it directly with Eclipse? in my case, no matter whether i use Run or Debug menu command in Eclipse, my apk always logs Config.DEBUG as false, although obviously the apk is signed with the key in factory debug.store. please help. thank you! -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Displays on emulator, not on phone
someone said Config.DEBUG or Config.RELEASE may help. however, when i build and run my apk by the Debug menu item within Eclipse IDE, my apk always logs Config.DEBUG to be false. do you or anyone else have an idea of how to have a DEBUG build and have Config.DEBUG to have correct value (true)? thank you.

[android-developers] Re: Audio Flickering - my code, my computer or android emulator?
(samples) i can imagine that the write will block long enough for the AudioRecord to overflow as you don't read in the next buffer of samples early enough. You could try decreasing the number of samples you read and write so the write will not block as long.

no chopping, likely because my computer (Core2 E8400) is lightening
fast.
my AudioRecord.read() returns a value equal to my buffer size, too.
however, it returns recorded samples in a speed faster than 8khz,
which makes later playback sound like my voice is slowed.
again, the same code works correctly on 1.5 emulator.

[android-developers] Re: How to add my own Audio codec to AudioRecord?
i believe you should use a short[] buffer in your AudioRecord.read().
on return, you pass the short[] buffer to you encoder and that is it.
On Mar 10, 3:39 am, draf...@gmail.com draf...@gmail.com wrote:
I currently have a Loop back program for testing Audio on Android
devices.
It uses AudioRecord and AudioTrack to record PCM audio from the Mic
and play PCM audio out the earpiece.
Here is the code:
public class Record extends Thread
{
static final int bufferSize = 20;
final short[] buffer = new short[bufferSize];
short[] readBuffer = new short[bufferSize];
public void run() {
isRecording = true;
android.os.Process.setThreadPriority
(android.os.Process.THREAD_PRIORITY_URGENT_AUDIO);
int buffersize = AudioRecord.getMinBufferSize(11025,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT);
arec = new
AudioRecord(MediaRecorder.AudioSource.MIC,
11025,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT,
buffersize);
atrack = new
AudioTrack(AudioManager.STREAM_VOICE_CALL,
11025,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT,
buffersize,
AudioTrack.MODE_STREAM);
atrack.setPlaybackRate(11025);
byte[] buffer = new byte[buffersize];
arec.startRecording();
atrack.play();
while(isRecording) {
arec.read(buffer, 0, buffersize);
atrack.write(buffer, 0,
buffer.length);
}
}
}
So as you can see in the creation of the AudioTrack and AudioRecord
the Encoding is supplied via the AudioFormat but this only allows 16
bit or 8 bit PCM.
I have my own G711 Codec implementation now and I want to be able to
encode the audio from the Mic and decode it going into the EarPiece,
So I have encode(short lin[], int offset, byte enc[], int frames) and
decode(byte enc[], short lin[], int frames) methods but I'm unsure as
to how to use them to encode and the decode the audio from the
AudioRecord and AudioTrack.
Can anyone help me or point me in the right direction?

[android-developers] Re: Can´t create an AudioRecor der object
what is the value of the variable SAMPLE_RATE?
On Mar 6, 7:15 pm, Gabriel Simões gsim...@gmail.com wrote:
First off, thank you for you attention and your help!
I´ve been trying to create a simple application to learn how android
handles audio streams for computer music and digital audio processing
applications.
Before I start coding I´ve read a lot of material (threads and
tutorials) about AudioRecorder so I could find my way but
unfortunately I´m facing a problem that neither google search can find
recurrencies. Believe it or not! hehehe
Here is the deal ...
When my application tries to create a new object from AudioRecorder I
get 3 error messages (Logcat):
03-07 02:58:43.048: ERROR/AudioRecord(371): Could not get audio input
for record source 1
03-07 02:58:43.048: ERROR/AudioRecord-JNI(371): Error creating

03-07 02:58:43.109: ERROR/AudioRecord-Java(371):
[ android.media.AudioRecord ] Error code -20 when initializing native
AudioRecord object.
Here is the code I´m using for creating a new AudioRecorder object:
//---
package com.examples.audio;
import android.app.Activity;
import android.media.AudioFormat;
import android.media.AudioRecord;
import android.media.MediaRecorder;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
public class main extends Activity {
/** Called when the activity is first created. */
private TextView tvGravacao;
private AudioRecord audioRecord;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tvGravacao = (TextView) findViewById(R.id.tvGravacao);
int BUFFER_SIZE = AudioRecord.getMinBufferSize(8000,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT);
audioRecord = new AudioRecord(MediaRecorder.AudioSource.MIC,
SAMPLE_RATE,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT,
BUFFER_SIZE);
}
//---
Does anyone have an idea of what could cause this error? My AVD has
been set up to handle audio input and output, I have recreated it
twice, have tried adding a permission in AndroidManifest.xml but none
of them solved my problem.
I hope someone has figured this out before.
Thanks,
Gabriel Simões
things I have noticed: sample rate must be 8000 and audioformat must
be ENCODING_PCM_16BIT. SR = 44100 or AF = 8 bit crashes app when
running AudioRecord.getMinBufferSize();

[android-developers] don't panic in case you see exception java.net.SocketException: The socket level is invalid....
just found this and would like to share my fix with you folks in case you run into the exception: if your app sees the exception: java.net.SocketException: The socket level is invalid dont be panic. it occurs when ip of your phone has changed and your app sends packets via a socket which is still bound to old ip. refreshing ip value and rebinding the socket to the new ip will fix the exception. the exception likely occurs to only real phones, i guess. happy weekend android coding to you folks ~.~ -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] i was beaten by AudioRecord :-(
after i upgraded SDK from 1.5r2 to 1.6, i found a serious problem: 1). on emulator 1.6, my app using AudioRecord records at a significantly faster pace than on 1.5 emulator. for example, after 30 seconds of audio recording (8kHz/mono) on 1.6 emulator, my app records 340,800 samples, which is equivalent to 348000/8000 = 42 secs of voice. playing back these samples at 8kHz sounds obviously like slowed down spacewalks on the moon. originally on 1.5 emulator, the same app recorded correctly 240,000 samples. 2). on my G1 phone, the same app built with SDK 1.6 records and plays back audio frames correctly. originally with SDK 1.5, the same app code always lost 5-10 secs of voice frames after 30secs of recording, because the recorder seemed to run out of G1 cpu power, which made AudioRecord.read() unable to read off recorded frames *in time*. though my app seems to run on G1 phone with my satisfaction, i am confused with the weird and inconsistent behavior of AudioRecord class described above. could any Android fork or anyone who is knowledgeable of this issue shed some light to me, telling how i can let AudioRecord sample voice frames at identical paces on G1 and emulator? thanks a lot in advance -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: what is the CRITICAL POINT of view layout to get hit by StackOverflowError exception
Mark, thank you so much for the pointer and information!! you are right on the tabs and activity. the view hierarchy depth of my activity is only 6 but, because the activity is 'hosted' by another TabActivity, the total depth on StackOverflowError exception is 13 (6+7). what i don't understand is: 1). is the critical point measured by the depth of hierarchy or by the total memory size used by all the views on the hierarchy? 2). how does setBackgroundResource() increase the depth or memory usage of 'the stack'? thanks again!!

Use hierarchyviewer both to determine your View hierarchy depth and determine where you may be able to consolidate some containers, to reduce the hierarchy depth and in turn eliminate your stack size problem. One of the reasons I rail against the use of activities as the contents of tabs, for example, is because doing so is very wasteful from a View hierarchy standpoint. Just switching those to be Views in tabs, rather than Activities in tabs, can clear up problems. -- Mark Murphy (a Commons Guy)http://commonsware.com|http://twitter.com/commonsguy Android Development Wiki:http://wiki.andmob.org -- You received this message because you are subscribed to the Google Groups Android Developers group.

with one of the AdSense for Mobile engineers on my issue since it
seems to only occur in my game with the ads turned on and he suggested
I post on the developer forum so I could have one of the framework
engineers look at it as well. I was able to build a small sample app
that reproduces the problem. I'd rather not post it here since it
contains my ad sense client and channel ids.

[android-developers] Re: BufferedReader.readLine hangs after HTTP connection has ended
Does T-Mobile proxy HTTP connection on its 3G/Edge network?
I have this question because my server always sends HTTP message body
in chunks with a Transfer-Encoding: chunked header. But when the
message arrives at my G1 phone, the header is gone and message body
is not chunked!!
Is it possible that TM proxy hold HTTP connections toward my G1 after
my server has say bye-bye to the proxy?
Can anybody confirm this?
On Jun 22, 5:49 pm, HeHe cnm...@gmail.com wrote:
I found my application run differently on G1 from Android emulator.
I used Ethereal to capture HTTP messages. I saw in both cases that the
server ended HTTP connection in 3 seconds after it finished sending
data.
Here is the related code snippet in my Android application:
InputStreamReader br=new BufferedReader(new
InputStreamReader
(sock.getInputStream()));
String line;
while ((line=br.readLine())!=null)
{
...code to process each line
}
When the code runs on Android emulator, the while loop exits almost
immediately after HTTP connection terminates.
However, when it runs on G1 phone, the while loop does not exit until
60+ seconds after TTP connection terminates.
Using G1, have you experienced similar problem??? If you have, how
did you work around the problem?
Thanks in advance for any advice!!!
