SimpleExoPlayer doesn't stream for the second time

I want to play a radio channel from url by using SimpleExoPlayer, the code works only for the first time, i.e., when I press play it works, then I press again it stops. But if I press again play button it doesn't play.
I tried to delete cache in every stop event but it also didn't solve the problem.

Exoplayer audio playing background even video was closed

Below is My fragment that contains exoplayer which will inflate with draggable panel in Activity. My problem is while swiping the draggable panel left or right video is closing but audio is still playing in background. If I swipe off the draggable panel audio also needs to closed.Tried many sources couldn't found any solutions.Also In both fragment and Activity while swipping off the draggable panel onPause() method is not triggred. Also public void onClosedToLeft() method also not getting called.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.dragpanelone, container, false);
try {
exoPlayerView = (SimpleExoPlayerView)v.findViewById(R.id.exoplayer);
BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelector trackSelector = new DefaultTrackSelector(new AdaptiveTrackSelection.Factory(bandwidthMeter));
exoplayer = ExoPlayerFactory.newSimpleInstance(getActivity(), trackSelector);
Uri uri = Uri.parse(videoURL);
DefaultHttpDataSourceFactory dataSourceFactory = new DefaultHttpDataSourceFactory("exoplayer_video");
ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
MediaSource mediaSource = new ExtractorMediaSource(uri, dataSourceFactory, extractorsFactory, null, null);
exoPlayerView.setPlayer(exoplayer);
exoplayer.prepare(mediaSource);
exoplayer.setPlayWhenReady(true);
} catch (Exception e){
e.printStackTrace();
}
return v;
}
#Override
public void onDestroy() {
super.onDestroy();
exoplayer.release();
}
#Override
public void onStop() {
super.onStop();
exoplayer.setPlayWhenReady(false);
}
public void pausePlayback() {
exoplayer.setPlayWhenReady(false); //pauses the playback if it's playing
}
private void releasePlayer() {
if (exoplayer != null) {
exoplayer.release();
exoplayer.setPlayWhenReady(false);
exoplayer = null;
}
}
public static void closePlayer()
{
exoplayer.clearVideoSurface();
}
}
This is my Activity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initializeDraggablepanel();
hookDraggablePanelListners();
}
public void initializeDraggablepanel(){
draggablepanel = (DraggablePanel)findViewById(R.id.draggable_panel);
draggablepanel.setFragmentManager(getSupportFragmentManager());
draggablepanel.setTopFragment(new DragpanelFragOne());
draggablepanel.setBottomFragment(new DragPanelTwo());
draggablepanel.setTopViewHeight(550);
draggablepanel.initializeView();
}
private void hookDraggablePanelListners(){
draggablepanel.setDraggableListener(new DraggableListener() {
#Override
public void onMaximized() {
}
#Override
public void onMinimized() {
}
#Override
public void onClosedToLeft() {
DragpanelFragOne.closePlayer();
Intent i = new Intent(MainActivity.this,HomeScreen.class);
startActivity(i);
}
#Override
public void onClosedToRight() {
DragpanelFragOne.closePlayer();
Intent i = new Intent(MainActivity.this,HomeScreen.class);
startActivity(i);
}
});
}
#Override
public void onPause() {
super.onPause();
DragpanelFragOne.closePlayer();
}
#Override
public void onStop() {
super.onStop();
draggablepanel.closeToLeft();
}
#Override
public void onBackPressed() {
draggablepanel.isClickToMinimizeEnabled();
Intent i = new Intent(MainActivity.this,HomeScreen.class);
startActivity(i);
}
}

Solution:
You need to call the method stop() on the exoplayer object whenever you are closing the player, like this:
if (exoPlayer != null) {
exoPlayer.setPlayWhenReady(false);
exoPlayer.stop();
exoPlayer.seekTo(0);
}
Hope this helps.

Pause ExoPlayer when headphones unplugged

How do I change the playback state of ExoPlayer when the Broadcast receiver is triggered?
I have a BroadcastReceiver that gets triggered when the headset is disconnected however I am not sure of the correct way to handle the pausing of audio when onReceive() is called. Do I need to change the playback state of the Mediasession here?

You should register the Receiver first in the Activity like -
MediaReceiver mr = new MediaReceiver(mPlayerView);
registerReceiver(mr);
then,
private class MediaReceiver extends BroadcastReceiver {
private PlayerView pv;
public MediaReceiver(PlayerView playerView) {

pv.pause();
}
}
also, don't forget to unregister Receiver in onDestroy() or onPause()

Exoplayer 2.11.0 supports setHandleAudioBecomingNoisy:
SimpleExoPlayer.Builder(this).setHandleAudioBecomingNoisy(true).build()

how to stop audio playing in background in exoplayer

In your fragment-holding activity, you need to handle the situation in the onPause method:
#Override
protected void onPause() {
super.onPause();
mPlayerFragment.pause();
}
You can define a method in your fragment to pause playback by passing false to setPlayWhenReady().
public void pausePlayback() {
mExoPlayer.setPlayWhenReady(false); //pauses the playback if it's playing
}

I am facing same issue and problem resolved after implement below code in my existing code
First You need to create global variable
boolean isActivityRunning = false;
Set this value in onCreate() and onResume() of activity to true.
You need to set Player if value isActivityRunning is true
After that you need to release player and set isActivityRunning = false in onPause(), onStop() and onDestroy() that look like
#Override
public void onPause() {
super.onPause();
isActivityRunning = false;
releasePlayer();
}
#Override
public void onStop() {
super.onStop();
isActivityRunning = false;
releasePlayer();
}
#Override
public void onBackPressed() {
super.onBackPressed();
releasePlayer();
}
#Override
protected void onDestroy(){
super.onDestroy();
releasePlayer();
}
and releasePlayer() implementation look like is
SimpleExoPlayer player;
PlayerView playerUI;
private void releasePlayer(){
if(player!=null){
player.release();
player.clearVideoSurface();
playerUI.getPlayer().release();;
player = null;
playerUI =null;
}
}
Where player and player UI is Global variable that need to set null
This solution work well for me.

How I get ExoPlayer to resume a video in my Activity's onStart() method?

I'm using ExoPlayer to play some mp4's from a URL. When the user click's the home button, or anything that causes the app to be removed from the user's view and then comes back to my app (and video activity) I want the video to resume where it left off. I tried implementing this by saving the video position in onStop() and then rebuilding the player and using seekTo() in onStart(). I have a check to see if my current exoplayer is null in onStart(), this check never passes however, so I think this is where the problem lies. How it's coded now my video never resumes. If I leave the app by pressing the home button onStop() gets called and then onStart() will get called when I go back into my app, however the video player remains black and never plays the video. If I remove the null check I get two instances of the video playing whenever I start a video from the main activity because it gets called both in onCreate() and onStart(). Is there a better method for getting the functionality that I want? Any help is appreciated!

Currently you're calling release in onStop() which will null out all the important pieces of the player, but not the exoPlayer field (and destroy any state that you aren't keeping track of yourself).
There are a few different approaches. But no matter what you do, you'll likely want to keep track of some state yourself. Below I use them as fields, but they could also be placed in onSavedInstanceState(). In onStop() we're saving off two pieces of information and then pulling them out in onStart(). 1) The last position our player was in when pausing and 2) whether we should play when resumed. You can likely move your seekTo call out of the if == null block since you'll probably always want to resume from where you left off.:
#Override
public void onStart() {
// ...
if (exoPlayer == null) {
// init player
}
// Seek to the last position of the player.
exoPlayer.seekTo(mLastPosition);
// Put the player into the last state we were in.
exoPlayer.setPlayWhenReady(mPlayVideoWhenForegrounded);
// ...
}
#Override
public void onStop() {
// ...
// Store off if we were playing so we know if we should start when we're foregrounded again.
mPlayVideoWhenForegrounded = exoPlayer.getPlayWhenReady();
// Store off the last position our player was in before we paused it.
mLastPosition = exoPlayer.getCurrentPosition();
// Pause the player
exoPlayer.setPlayWhenReady(false);
// ...
}
Now the other issue I see with your code sample is that exoPlayer.release() won't null out the field exoPlayer. So you could additionally add the line exoPlayer = null after exoPlayer.release() which should hopefully fix your issue of multiple exoPlayers. You could also move the release() call to onDestroy() but only if you know you're reinstantiating everything correctly.

There is no need to reinit player again. The following code is pretty enough:
#Override
protected void onPause() {
super.onPause();
if (player!=null) {
player.stop();
mLastPosition = player.getCurrentPosition();
}
}
#Override
protected void onResume() {
super.onResume();
//initiatePlayer();
if(mLastPosition!=0 && player!=null){
player.seekTo(mLastPosition);
}
}

Try the following
Get the player position in onPause.
initiate the palyer again in onResume and set seek to the last position of the player
private void initiatePlayer() {
try {
exoPlayer = ExoPlayerFactory.newSimpleInstance(this);
DataSource.Factory dataSourceFactory =
new DefaultDataSourceFactory(this, Util.getUserAgent(this, this.getResources().getString(R.string.app_name)));
DefaultExtractorsFactory extractorsFactory =
new DefaultExtractorsFactory()
.setMp4ExtractorFlags(Mp4Extractor.FLAG_WORKAROUND_IGNORE_EDIT_LISTS);
ProgressiveMediaSource progressiveMediaSource =
new ProgressiveMediaSource.Factory(dataSourceFactory, extractorsFactory)
.createMediaSource(videoUri);
// playerView = new PlayerView(this);
playerView.setPlayer(exoPlayer);
exoPlayer.prepare(progressiveMediaSource);
exoPlayer.setPlayWhenReady(true);
PlayerControlView controlView = playerView.findViewById(R.id.exo_controller);
mFullScreenIcon = controlView.findViewById(R.id.exo_fullscreen_icon);
ImageView volumeControl = controlView.findViewById(R.id.exo_volume);
mFullScreenIcon.setOnClickListener(new View.OnClickListener() {

}
}, 2000);
}
});
volumeControl.setOnClickListener(view -> {
float currentvolume = exoPlayer.getVolume();
if (currentvolume > 0f) {
previousVolume = currentvolume;
exoPlayer.setVolume(0f);
volumeControl.setImageDrawable(ContextCompat.getDrawable(this, R.drawable.ic_volume_off_white_24dp));
} else {
exoPlayer.setVolume(previousVolume);
volumeControl.setImageDrawable(ContextCompat.getDrawable(this, R.drawable.ic_volume_up_white_24dp));
}
});
} catch (Exception e) {
e.printStackTrace();
Log.d("MainExcep", e.getMessage());
}
}

In my case, if i minimize or try to move from the this player video app to another app. The video player app always starting play from 0. I was try and succesfully, the video player app playing video from the last current position when you minimalize or move to another app, and this it.
go to
private void buildPlayer(String mp4Url)
add
player.seekTo(playbackPosition);
and then
#Override

super.onResume();
if(playbackPosition!=0 && player!=null){
player.seekTo(playbackPosition);
initializePlayer();
}
}
#Override
public void onPause() {

player.stop();
if(player != null && player.getPlayWhenReady()) {
player.stop();
playbackPosition = player.getCurrentPosition();
player.setPlayWhenReady(true);
}
