If we open our app the news fragment is loaded and the news automatically starts to play. We are using Exoplayer for playing the news. Notification is created by Exoplayer via PlayerNotificationManager. The problem is that the play pause button doesn't follow the notification. We have implemented eventbus & it only changes the drawable. So, if we click on pause button on the notification, the button on fragment is seen as paused but when we click on it works as a pause button (instead of working as a play button).
What we intend to do is: If the notification says paused the button on fragment will be paused & then if we click on it the content will start to play.
Codes:
NewsReaderFragment.java
public static NewsReaderFragment newInstance() {
return new NewsReaderFragment();
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

PlayerNotificationManager.java
It's a big file, so we are attaching only the receiver where we use eventbus:
public class NotificationBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Player player = PlayerNotificationManager.this.player;
if (player == null
|| !isNotificationStarted
|| intent.getIntExtra(EXTRA_INSTANCE_ID, instanceId) != instanceId) {
return;
}
String action = intent.getAction();
if (ACTION_PLAY.equals(action)) {
if (player.getPlaybackState() == Player.STATE_IDLE) {
if (playbackPreparer != null) {
playbackPreparer.preparePlayback();
}
} else if (player.getPlaybackState() == Player.STATE_ENDED) {
controlDispatcher.dispatchSeekTo(player, player.getCurrentWindowIndex(), C.TIME_UNSET);
}
controlDispatcher.dispatchSetPlayWhenReady(player, /* playWhenReady= */ true);
EventBus.getDefault().post(new ButtonEvent(true));
Log.d(TAG, "ButtonEvent: True");
} else if (ACTION_PAUSE.equals(action)) {
controlDispatcher.dispatchSetPlayWhenReady(player, /* playWhenReady= */ false);
if (player.getPlaybackState() == Player.STATE_READY)
{
EventBus.getDefault().post(new ButtonEvent(false));
Log.d(TAG, "ButtonEvent: False");
}
} else if (ACTION_STOP.equals(action)) {
controlDispatcher.dispatchStop(player, /* reset= */ true);
} else if (ACTION_DISMISS.equals(action)) {
stopNotification(/* dismissedByUser= */ true);
} else if (action != null
&& customActionReceiver != null
&& customActions.containsKey(action)) {
customActionReceiver.onCustomAction(player, action, intent);
}
}
}
ButtonEvent.java
public class ButtonEvent {
public boolean state;
public ButtonEvent(boolean state) {
this.state = state;
}
public boolean isState() {
return state;
}
public void setState(boolean state) {
this.state = state;
}
}
Is it correct that isPlaying is true in this scenario, executing a second pause?
private void setButton() {
bPlay.setOnClickListener(view -> {
if (!isPlaying) {
exoHelper.startExo(rootView.getContext().getString(R.string.bbc_news));
} else {
exoHelper.stopExo();
}
isPlaying = !isPlaying;
});
}
Is there a reason why the state of whether it is playing it tied to the Fragment and not ExoHelper?
Maybe this can be remedied easily by re-assigning isPlaying with exoplayers event listener...
player.addListener(eventListener);
...
#Override
public void onIsPlayingChanged(boolean isPlaying) {
if (isPlaying) {
// player is playing
} else {
// player is paused
}
}
UPDATE
Or query exoplayer directly for state:
private void setButton() {
bPlay.setOnClickListener(view -> {
if (!isPlaying()) {
exoHelper.startExo(rootView.getContext().getString(R.string.bbc_news));
} else {
exoHelper.stopExo();
}
});
}
// this method might belong in ExoHelper?
private boolean isPlaying() {
return player.getPlaybackState() == Player.STATE_READY && player.getPlayWhenReady();
}

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;

This is my Activity

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.
In my App, I have fragment in which I, alongside with other, play video in ExoPlayer. I set it up as simple as possible and the player itself works flawlessly, even with media session.
But the problem is that on device rotation, the video loads again in background (there seems to be two layers - one standard, functioning normally, loading video and playing it; and second layer in background. I can hear the sound of the video shortly after the activity recreates.
I am stopping and releasing the player and media session, but it didn't help.

Solved...
I was using add() to create the Fragment, so on rotation it added new one.
Using replace instead solved the problem.
I am using ExoPlayer in my activity,What i want is to smoothly play video in portrait and landscape mode.For this purpose what I am doing is in onpause I save the currentPlayerPosition and seek player to that position in onresume but while rotating it face a jerk and video is stopped for a while and played to the saved position.
My code is below please help me how i can smoothly switch the mode portrait and landscape.Thanks

Finally, After wasting 2 days I found it.
Simple add it in the manifest and will work on all android version ?
android:configChanges="orientation|screenSize|layoutDirection"
cheers!
If you want the video to resume on orientation change, you can add this to your manifest android:configChanges="keyboardHidden|orientation|screenSize"
<activity
<activity
android:name=".MainActivity"
android:name=".MainActivity"
android:label="#string/app_name"
android:label="#string/app_name"
+ android:configChanges="keyboardHidden|orientation|screenSize"
android:theme="#style/AppTheme.NoActionBar"
android:theme="#style/AppTheme.NoActionBar"
android:icon="#mipmap/ic_launcher_2">
android:icon="#mipmap/ic_launcher_2">
<intent-filter>
<intent-filter>
No need of any additional coding, simply add this line
android:configChanges="keyboardHidden|orientation|screenSize"
in your AndroidManifest.xml's activity section.
I also wasted quite a lot time in this. Take a look at it EXO PLAYER 2.11.2
implementation 'com.google.android.exoplayer:exoplayer:2.11.2'
STEP - 1 Make an activity in which string url is passed as intent.
public class VideoPlayerActivity extends Activity {
public static final String sURL_KEY = "STREAMING_URL_KEY";
public static final String sTOAST_TEXT = "Unable to stream, no media found";
static final String LOADING = "PLAYER_LOADING";
static final String STOPPED = "PLAYER_STOPPED";
static final String PAUSED = "PLAYER_PAUSED";
static final String PLAYING = "PLAYER_PLAYING";
static final String IDLE = "PLAYER_IDLE";
private static final String TAG = "StreamMediaActivity";
int orientation;
private Uri streamUrl;
private SimpleExoPlayer mPlayer;
private PlayerView playerView;
private ProgressBar progressBar;
private String mPlayerStatus;
private long mPlaybackPosition = 0L;
private boolean mIsPlayWhenReady = true;
private int mCurrentWindow = 0;
private Display display;
private String STATE_RESUME_WINDOW = "resumeWindow";
private String STATE_RESUME_POSITION = "resumePosition";
private String STATE_PLAYER_FULLSCREEN = "playerFullscreen";
private boolean mExoPlayerFullscreen = false;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
fullScreen();
display = ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay();
orientation = display.getRotation();
setContentView(R.layout.activity_video_player);
playerView = findViewById(R.id.player_view);
progressBar = findViewById(R.id.progressBar_player);
// Pass a string uri to this class
String urlString = getIntent().getStringExtra(sURL_KEY);
if (urlString != null) {
streamUrl = Uri.parse(urlString);
} else {
Toast.makeText(this, sTOAST_TEXT, Toast.LENGTH_LONG).show();
finish();
}
}
#Override
protected void onStart() {
super.onStart();
initPlayer();
}
#Override
protected void onResume() {
super.onResume();
if (mPlaybackPosition != 0L && mPlayer != null) {
mPlayer.seekTo(mCurrentWindow, mPlaybackPosition);
}
}
#Override
protected void onStop() {
super.onStop();
}
#Override protected void onPause() {
super.onPause();
releasePlayer();
}
private void initPlayer() {
// ESTABLISH THE DATA SOURCE FROM URL
// here i'm playing local video file that's
// why using the DefaultDataSourceFactory but you
//may use DefaultHttpDataSourceFactory to stream
//online videos
DataSource.Factory dataSourceFactory =
new DefaultDataSourceFactory(this, Util.getUserAgent(this, getApplicationInfo().name));
MediaSource mediaSource =
new ProgressiveMediaSource.Factory(dataSourceFactory).createMediaSource(
streamUrl);
// CREATE A NEW INSTANCE OF EXO PLAYER
if (mPlayer == null) {
mPlayer = new SimpleExoPlayer.Builder(this, new DefaultRenderersFactory(this)).build();
playerView.setPlayer(mPlayer);
progressBar.setVisibility(View.VISIBLE);
}
mPlayer.setPlayWhenReady(mIsPlayWhenReady);
mPlayer.seekTo(mCurrentWindow, mPlaybackPosition);
// PREPARE MEDIA PLAYER
mPlayer.prepare(mediaSource, true, false);
mPlayer.addListener(new Player.EventListener() {
#Override
public void onPlayerStateChanged(boolean playWhenReady, int playbackState) {
switch (playbackState) {
case Player.STATE_BUFFERING:
mPlayerStatus = LOADING;
runOnUiThread(() -> progressBar.setVisibility(View.VISIBLE));
break;
case Player.STATE_ENDED:
mPlayerStatus = STOPPED;
break;
case Player.STATE_READY:
mPlayerStatus = (playWhenReady) ? PLAYING : PAUSED;
runOnUiThread(() -> progressBar.setVisibility(View.INVISIBLE));
break;
default:
mPlayerStatus = IDLE;
break;
}
}
#Override
public void onPlayerError(ExoPlaybackException error) {
Toast.makeText(VideoPlayerActivity.this, "Something went wrong", Toast.LENGTH_SHORT).show();
finish();
}
});
}
#Override protected void onSaveInstanceState(Bundle outState) {
mExoPlayerFullscreen = !mExoPlayerFullscreen;
super.onSaveInstanceState(outState);
outState.putInt(STATE_RESUME_WINDOW, mCurrentWindow);
outState.putLong(STATE_RESUME_POSITION, mPlaybackPosition);
outState.putBoolean(STATE_PLAYER_FULLSCREEN, mExoPlayerFullscreen);
super.onSaveInstanceState(outState);
}
public void fullScreen() {
View decorView = getWindow().getDecorView();
decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);
}
private void releasePlayer() {
if (mPlayer != null) {
mPlayer.stop();
mPlaybackPosition = mPlayer.getCurrentPosition();
mCurrentWindow = mPlayer.getCurrentWindowIndex();
mIsPlayWhenReady = mPlayer.getPlayWhenReady();
playerView.setPlayer(null);
mPlayer.release();
mPlayer = null;
}
}
}
Step 2 : Make the XML layout
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/black">
<FrameLayout
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<com.google.android.exoplayer2.ui.PlayerView
android:id="#+id/player_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_constraintBottom_toBottomOf="parent"
android:keepScreenOn="true"
app:use_controller="true"
app:resize_mode="fit"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<ProgressBar
android:id="#+id/progressBar_player"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" />
</FrameLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
STEP 3: start VideoPlayerActivity using intent from another activity
Intent streamVideoIntent = new Intent(context, VideoPlayerActivity.class);
streamVideoIntent.putExtra(sURL_KEY, stringUrl);
context.startActivity(streamVideoIntent);
STEP 4 : Lastly add activity to manifest
<activity android:name=".ui.videoplayer.VideoPlayerActivity"
android:configChanges="orientation|screenSize|layoutDirection"
/>
I'm working on the Android TV app which uses VideoView to play the video from the url. Each time the video is paused and then resumed - it takes some time to pre-download it first (few seconds during which progress bar appears). The goal is to buffer the video during playback so that when I pause it and then resume - it resumes from pre-buffered state immediately without delay. I've also tried videoView.resume() method, but it doesn't help either. Is there a way to do that or am I doing something wrong?
Here is the code which plays/resumes the video:
public void onFragmentPlayPause(final Video video,
final VideoQuality quality,
final int position,
final Boolean play) {
stopSeeking();
videoView.setVideoPath(video.videoUrl(quality));
if (position == 0 || playbackState == LeanbackPlaybackState.IDLE) {
setupCallbacks();
playbackState = LeanbackPlaybackState.IDLE;
}
if (play && playbackState != LeanbackPlaybackState.PLAYING) {
progressBar.setVisibility(View.VISIBLE);
playbackState = LeanbackPlaybackState.PLAYING;
if (position > 0) {
videoView.seekTo(position);
videoView.start();
}
playbackFragment.startProgressObservation(progressFlowable());
} else {
playbackState = LeanbackPlaybackState.PAUSED;
videoView.pause();
playbackFragment.stopProgressObservation();
}
updatePlaybackState(position);
updateMetadata(video);
}
Unfortunately, I've didn't find the way to achieve this with VideoView, only using ExoPlayer, thanks to #pskink for the right direction. The API was returning mp4 videos, so I've used ExtractorMediaSource. The complete demo example with support of multiple formats can be found on ExoPlayer GitHub page.
Here is the final code I've ended up with using ExoPlayer:
private void playPause(final Video video, final int position, final Boolean play) {
if (position == 0 || playbackState == LeanbackPlaybackState.IDLE) {
setupCallbacks();
playbackState = LeanbackPlaybackState.IDLE;
}
if (play && playbackState != LeanbackPlaybackState.PLAYING) {
progressBar.setVisibility(View.VISIBLE);
playbackState = LeanbackPlaybackState.PLAYING;
player.start();
playbackFragment.startProgressObservation(progressFlowable());
} else {
playbackState = LeanbackPlaybackState.PAUSED;
player.pause();
playbackFragment.stopProgressObservation();
}
updatePlaybackState(position);
updateMetadata(video);
}

I'm working on a music player for android and i'm stuck at this problem.
By now i can play a song with musicservice and send it to background, i also display a notification with current playing song.
What i need is to re-open the main activity from the song notification and continue playing the song, it actually starts the desired activity but the music service is re-created and it stops the current playing song.
Here is my code.

//initialize position
songPosition = 0;
//create player
player = new MediaPlayer();
initMusicPlayer();
}

//set player properties
player.setWakeMode(getApplicationContext(), PowerManager.PARTIAL_WAKE_LOCK);

(The fragment also re-creates itself when navigating through drawer menu items)
I hope somebody can help me achieve this. I dont know how to maintane the state when re-starting the MainActivity (by the way, im using navdrawer to hold fragments)
Include the currently playing song in your notification intent. Update the intent as the song changes. Include the flag to clear top and the flag to update current in the notification intent. :( sorry IDK if I have the flags right for your situation but you'll have a place to do more research.
In your service where you create the notification intent.
// link the notifications to the recorder activity
Intent resultIntent = new Intent(context, KmlReader.class);
resultIntent
.setAction(ServiceLocationRecorder.INTENT_COM_GOSYLVESTER_BESTRIDES_LOCATION_RECORDER);
resultIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent resultPendingIntent = PendingIntent
.getActivity(context, 0, resultIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(resultPendingIntent);
return mBuilder.build();
}
Then in main onCreate check the bundle for the name of the currently playing song and display it. Notice how I check for the existence of a bundle key before using it.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent = getIntent();
String intentaction = intent.getAction();
// First Run checks
if (savedInstanceState == null) {
// first run init
...
} else {
// get the saved_Instance state
// always get the default when key doesn't exist
// default is null for this example
currentCameraPosition = savedInstanceState
.containsKey(SAVED_INSTANCE_CAMERA_POSITION) ? (CameraPosition) savedInstanceState
.getParcelable(SAVED_INSTANCE_CAMERA_POSITION) : null;
...
