Pause all the other media players and audios while Application media player starts playing

I am working on a push to talk App, where the receiver will get a live-streamed audio message from a sender if he is connected to the internet. Now everything's working all fine except one issue that is: whenever any other applications like google music or youtube are playing audios, that time if I am getting an audio notification or message through the application, both the audios are playing in a parallel manner. I am using VoiceLayer library for the app and to play a message audio, they use VoiceLayerMessagePlayer. Is there any way I can pause the other media players when I am getting a notification or voice message in my Application? I looked through the internet and found out that OnAudioFocusChangeListener might be helpful but didn't get a proper example regarding its implementation. Please do let me know if you need any more information. Thanks in advance.

You should use AudioManager service to receive notification whether you receive/lost audio focus (Managing audio focus). I've done similar thing in a project where when my app starts playing, Google Play pause and vice versa. Use the following code where you are controlling your media playback like (activity or service)
Stop MediaPlayer when an other app play music

Please check below code it's working fine.
AudioManager am = null;
// Request focus for music stream and pass
AudioManager.OnAudioFocusChangeListener
// implementation reference
int result = am.requestAudioFocus(this, AudioManager.STREAM_MUSIC,
AudioManager.AUDIOFOCUS_GAIN);
if(result == AudioManager.AUDIOFOCUS_REQUEST_GRANTED)
{
// Play
}
// Implements AudioManager.OnAudioFocusChangeListener
#Override
public void onAudioFocusChange(int focusChange)
{
if(focusChange == AudioManager.AUDIOFOCUS_LOSS_TRANSIENT)
{
// Pause
}
else if(focusChange == AudioManager.AUDIOFOCUS_GAIN)
{
// Resume
}
else if(focusChange == AudioManager.AUDIOFOCUS_LOSS)
{
// Stop or pause depending on your need
}
}
Hope this helps you and solved your problem.

please try this code. it work with me
val audioManager = requireActivity().getSystemService(Context.AUDIO_SERVICE) as AudioManager
val focusRequest = AudioFocusRequest.Builder(AudioManager.AUDIOFOCUS_GAIN).run {
setAudioAttributes(AudioAttributes.Builder().run {
setUsage(AudioAttributes.USAGE_GAME)
setContentType(AudioAttributes.CONTENT_TYPE_MUSIC)
setOnAudioFocusChangeListener({ }, object : Handler() {})
build()
})
setAcceptsDelayedFocusGain(true)
build()
}
audioManager.requestAudioFocus(focusRequest)

Android system audio not working correctly after using setSpeakerPhoneOn of AudioManager

I'm trying to make a application that switches the audio play between the speaker and earpiece.
I'm using The following code:
public boolean setAudioMode(String mode) {
AudioManager audioManager =
(AudioManager) this.getSystemService(Context.AUDIO_SERVICE);
int currentVolume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, currentVolume, 0);
if (mode.equals("earpiece")) {
audioManager.setMode(AudioManager.STREAM_MUSIC);
audioManager.setSpeakerphoneOn(false);
this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
return true;
} else if (mode.equals("speaker")) {
audioManager.setMode(AudioManager.STREAM_MUSIC);
audioManager.setSpeakerphoneOn(true);
this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
return true;
}
return false;
}
This code is working and I can change the audio output correctly.
But after I close my application, my phone does not play any sound through my headphones and the volume control sticks to in call volume. My phone only go back to normal after a full restart.
What can I do to restore the phone audio? Or is there a better way to switch the audio output that does not make this problem?

how to turn speaker on/off programmatically in android 4.0

I play a file through media player and I want to give options like speaker on/off, play though headset, bluetooth ,etc.
I tried the below code which works well for android 2.2 but I want something that can also work for 2.2 and 4.0 both.
Can you help me to programmatically turn the speaker on/off and playing via headphones?
AudioManager audioManager = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
if(isOn){
audioManager.setMode(AudioManager.MODE_IN_CALL);
audioManager.setMode(AudioManager.MODE_NORMAL);
}else{
//Seems that this back and forth somehow resets the audio channel
audioManager.setMode(AudioManager.MODE_NORMAL);
audioManager.setMode(AudioManager.MODE_IN_CALL);
}
audioManager.setSpeakerphoneOn(isOn);
P.S: I have given this permission in manifest:
android.permission.MODIFY_AUDIO_SETTINGS

Something like this might work on some devices (I've only tested in on an XPeria P):
final static int FOR_MEDIA = 1;
final static int FORCE_NONE = 0;
final static int FORCE_SPEAKER = 1;
Class audioSystemClass = Class.forName("android.media.AudioSystem");
Method setForceUse = audioSystemClass.getMethod("setForceUse", int.class, int.class);
setForceUse.invoke(null, FOR_MEDIA, FORCE_SPEAKER);
// To get back to the default behaviour, use the combination FOR_MEDIA,FORCE_NONE.
The combination FOR_MEDIA, FORCE_SPEAKER is typically only used internally to route the FM-radio audio to the loudspeaker (since the FM-radio requires you to have a wired headset / headphone plugged in to act as an antenna). Devices that don't have FM-radio functionality (or uses an alternative implementation) might ignore this combination of parameters, so this method would not work on such a device.

AudioManager mAudioMgr = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
Button mVolumeButton = (Button)findViewById(R.id.btn_Volume);
mVolumeButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(mAudioMgr.isWiredHeadsetOn()){
mAudioMgr = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
mAudioMgr.setWiredHeadsetOn(false);
mAudioMgr.setSpeakerphoneOn(true);
mAudioMgr.setMode(AudioManager.MODE_IN_COMMUNICATION);
Toast.makeText(getApplicationContext(), "SpeakerPhone On", Toast.LENGTH_LONG).show();
}else{
mAudioMgr.setMode(AudioManager.MODE_IN_COMMUNICATION);
mAudioMgr.setSpeakerphoneOn(false);
mAudioMgr.setWiredHeadsetOn(true);
Toast.makeText(getApplicationContext(), "Wired Headset On", Toast.LENGTH_LONG).show();
}
}
});

You can acquire either a rear speaker or a front earpiece at time.
If no accessory connected;
Use audioManager.setMode(AudioManager.MODE_IN_CALL); & audioManager.setSpeakerphoneOn(false); to use front speaker/earpiece. But this would play audio in earpiece not on speaker. To use rear speaker, use audioManager.setMode(AudioManager.MODE_NORMAL); & audioManager.setSpeakerphoneOn(true);
If accessory connected; Use audioManager.setMode(AudioManager.MODE_IN_CALL); & audioManager.setSpeakerphoneOn(false); to use front speaker/earpiece. But this would play audio in earpiece not on speaker. To use rear speaker, use audioManager.setMode(AudioManager.MODE_IN_CALL); & audioManager.setSpeakerphoneOn(true);
Note: Make sure audioManager.setWiredHeadsetOn(boolean on) and audioManager.setBluetoothScoOn(boolean on) set to false to route audio via earpiece . And set either to true to route audio accordingly.

try follow code snippet:
//for speakerphone on
audioManager.setMode(AudioManager.MODE_NORMAL);
audioManager.setSpeakerphoneOn(true);
//for headphone on
audioManager.setMode(AudioManager.MODE_IN_COMMUNICATION);
audioManager.setSpeakerphoneOn(false);
BTW,I tested in Android 7.0(Redmi 4x) and it worked fine.

Problem solved. For all of you who are still searching for the answer. Well this is not a bug , but just a tricky thing . You need to use the PhoneStateListener
Using this guide : http://danielthat.blogspot.co.il/2013/06/android-make-phone-call-with-speaker-on.html

if u just want to open your speakerphone on u just write this line in oncreate() of your activity.
static AudioManager audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
audioManager.setMode(AudioManager.MODE_IN_CALL);
audioManager.setSpeakerphoneOn(true);

Try This.
AudioManager audioManager =(AudioManager)getSystemService(Context.AUDIO_SERVICE);
if (isOn) {
isOn = false;
audioManager.setMode(AudioManager.MODE_IN_CALL);
audioManager.setMode(AudioManager.MODE_NORMAL);
} else {
isOn = true;
audioManager.setMode(AudioManager.MODE_NORMAL);
audioManager.setMode(AudioManager.MODE_IN_CALL);
}
audioManager.setSpeakerphoneOn(isOn);

Try
AudioManager.speakerphone(true);
Look at this.

why is abandonAudioFocus not working in Android Music app

Im using this code to get AudioFocus and it works ok with
Android Music app ( the one preinstalled )
int result = audioManager.requestAudioFocus(meService, AudioManager.STREAM_MUSIC,AudioManager.AUDIOFOCUS_GAIN_TRANSIENT);
However when i release it with this code
audioManager.abandonAudioFocus(meService);
The Android Music app ( the one preinstalled ) does not continue playing.
if i use the AUDIOFOCUS_LOSS_TRANSIENT_CAN_DUCK it works
but Android Music app is not lowering the volume enough.
Any ides why Android Music app is not resuming playback?
im using api8 and using the onAudioFocusChange

You should release it in MediaPlay.onCompleteListener(){}

After trying 4 players non of them are ducking. I might be doing something wrong and would like to see that. I answer my own question that we have to live with this.

This way works fine for me.
public class HomeActivity extends Activity implements AudioManager.OnAudioFocusChangeListener {
// Other stuff
#Override
public void onAudioFocusChange(int focusChange) {
if (focusChange == AudioManager.AUDIOFOCUS_REQUEST_GRANTED) {
Log.i("HomeActivity", "Audio focus granted.");
}else if (focusChange == AudioManager.AUDIOFOCUS_REQUEST_FAILED) {
Log.i("HomeActivity", "Audio focus failed.");
}
}
}
Request AudioFocus:
private void requestAudioFocus(){
AudioManager am = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE);
// Request audio focus for playback
am.requestAudioFocus(this,
// Use the music stream.
AudioManager.STREAM_MUSIC,
// Request permanent focus.
AudioManager.AUDIOFOCUS_GAIN_TRANSIENT);
}
Abandon AudioFocus:
private void abandonAudioFocus(){
AudioManager am = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE);
am.abandonAudioFocus(this);
}
Hope this would help you.

Supplying option to user to play video with or without audio

I am using VideoView to play an mp4 video. I would like to give the user the option of watching this video with sound or mute the sound if he/she chooses. I do not use the mediaController allowing the user to stop and play, I have "touch" events controlling this.
UPDATE: I have a menu that I have added a "mute" icon to. Now I am trying to figure out how to add the mute to this button. I am reading some info on from the Android AudioManager, in particular the setStreamMute. Here is what the API's say:
public void setStreamMute (int streamType, boolean state)
Since: API Level 1
Mute or unmute an audio stream.
The mute command is protected against client process death: if a process with an active mute request on a stream dies, this stream will be unmuted automatically.
The mute requests for a given stream are cumulative: the AudioManager can receive several mute requests from one or more clients and the stream will be unmuted only when the same number of unmute requests are received.
For a better user experience, applications MUST unmute a muted stream in onPause() and mute is again in onResume() if appropriate.
This method should only be used by applications that replace the platform-wide management of audio settings or the main telephony application.
Parameters
streamType The stream to be muted/unmuted.
state The required mute state: true for mute ON, false for mute OFF

Use the AudioManager service to mute and unmute just the stream related to your video. From the method(s) you have declared to respond to the user touch events, call methods like:
public void mute() {
AudioManager am = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
am.setStreamMute(AudioManager.STREAM_MUSIC, true);
}
public void unmute() {
AudioManager am = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
am.setStreamMute(AudioManager.STREAM_MUSIC, false);
}
This will leave the other streams (notification, alarm, etc.) active so you aren't silencing the whole device just to mute the video.
Also, if you need to suggest to your Activity which stream it should be pushing the audio through you can call Activity.setVolumeControlStream(AudioManager.STREAM_MUSIC) to tie your Activity's window to that stream.

I was able to implement my desire to have a mute button contained in a menu button. Each time the user interacts with the button, the video either mutes or unmutes. Here is the code:
private AudioManager mAm;
private boolean mIsMute;
// Audio mgr
mAm = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
mIsMute = false;
public void isMute() {
if(mIsMute){
mAm.setStreamMute(AudioManager.STREAM_MUSIC, false);
mIsMute = false;
}else{
mAm.setStreamMute(AudioManager.STREAM_MUSIC, true);
mIsMute = true;
}
}
And then inside my case:
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()){
// Mute
case R.id.main_menu_mute:
isMute();
break;
.........
}
return super.onOptionsItemSelected(item);
}
