Unfortunately, does not work for me. I tested on Nexus 5 (Marshmallow) and Moto G (Lollipop). Using appcompat v 23.1.1.
I can confirm that it is not working on Nexus 5 with Marshmallow, however it is working on Kitkat in Visual Studio Emulator. Any ideas whats wrong on Marshmallow?
FIX:
In onCreate before AudioManager:
mediaSession.setCallback(mMediaSessionCallback);
Add this in outside of onCreate:
private final MediaSessionCompat.Callback mMediaSessionCallback
= new MediaSessionCompat.Callback() {
@Override
public boolean onMediaButtonEvent(Intent mediaButtonEvent) {
final String intentAction = mediaButtonEvent.getAction();
if (Intent.ACTION_MEDIA_BUTTON.equals(intentAction)) {
final KeyEvent event = mediaButtonEvent.getParcelableExtra(
Intent.EXTRA_KEY_EVENT);
if (event == null) {
return super.onMediaButtonEvent(mediaButtonEvent);
}
final int keycode = event.getKeyCode();
final int action = event.getAction();
if (event.getRepeatCount() == 0 && action == KeyEvent.ACTION_DOWN) {
switch (keycode) {
// Do what you want in here
case KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE:
Log.d("MPS", "KEYCODE_MEDIA_PLAY_PAUSE");
break;
case KeyEvent.KEYCODE_MEDIA_PAUSE:
Log.d("MPS", "KEYCODE_MEDIA_PAUSE");
break;
case KeyEvent.KEYCODE_MEDIA_PLAY:
Log.d("MPS", "KEYCODE_MEDIA_PLAY");
break;
}
}
}
return super.onMediaButtonEvent(mediaButtonEvent);
}
};
It looks like Android 21+ (at least for me) doesn't hit the BroadCastReceiver. This does.
Hi All, I have used the same code which is there above. I can see the notifications, but i can't control it.. The MediaEvent is not triggering and It doesn't recognize when I pressed Pause, Previous .etc.
Help Needed. Thanks
@immran Do you register <action android:name="android.intent.action.MEDIA_BUTTON"/>
for RemoteReceiver in Manifests ?
I have found that the image does not show up on Marshmallow when the PlaybackState is set to PAUSED (which is the default state in this example). It does show when the state is PLAYING.
I have got album art and notification on lock screen with this code,but there are no buttons. I'm using Android 6.0. Do you have any idea?
Anyone used MediaSessionCompat with MediaBrowserServiceCompat?
putLong(MediaMetadataCompat.METADATA_KEY_DURATION, 10000); duration is displayed as 10, which I believe its because dividing 10000 by 1000 to get seconds format. But why 10000? How do I get the original duration of the track being played?
I have implemented the above example but it does not seem to show anything on the lockscreen. I am receiving the mediasession callbacks but the nothings seems to show up on the lock screen. Any ideas what is going wrong?
FYI: I am using support library 25.1.0
I am using this in an Activity and successfully receive the media buttons. However, in the lock screen nothing is displayed (even though the activity is in the background and with the mediaplayer active). Does the lockscreen functionality require a service?
How can I add SongList to the Queue of the session from activity? I can not see any kind of post regarding it.
I tried
mediaSessionCompat = MediaSessionCompat.fromMediaSession(mainActivity,mediaBrowserCompat.getSessionToken());
mediaSessionCompat.setQueue(queueList);
gives an error mediaSession is not a valid MediaSession object
I created a trivial working app project from this Gist at https://github.com/gregko/PlayerServiceSample. In the LogCat output one can see a message when a media button is pressed on a headset, when running on Android 5.x through 7.x. However it fails completely on Android 8 "Oreo", which final build Google just released. Would appreciate any hints on how to make this work under "Oreo", thanks!
i am getting same issue i have created one app in that one bluetooth device is bind with phone and according to event its working fine in below oreo but in that oreo not getting any action event if any one idea help me to solve out
I cannot change to "play" button, the button always show "pause", if i change to state to paused the playback screen not showing anything
This code not show anything
mediaSession.setPlaybackState(new PlaybackStateCompat.Builder()
.setState(PlaybackStateCompat.STATE_PAUSED, 0, 0.0f)
.setActions(PlaybackStateCompat.ACTION_PLAY_PAUSE).build());
Thanks for this. Not a lot of examples around.
