    simpleExoPlayer.release();

}

}

and this is my media player initialisation ::::::::::::::

public void prepareMedia() { isPlaying=true; simpleExoPlayer = new SimpleExoPlayer.Builder(MediaPlayer_Activity.this).build(); MediaItem mediaItem = MediaItem.fromUri(audioUrl); simpleExoPlayer.addMediaItem(mediaItem); simpleExoPlayer.prepare(); simpleExoPlayer.seekTo(songPrevPosition); }

Please tell me what's wrong LogCat is not showing anything I don't know how to stop this and where the problem is.... please help

CodePudding user response：

After 9 Android version we have protections for simple service. Simple service can live 10 seconds, no more. You need to declare you service as Foreground Service. It will look like notification in status bar.

For fully information read documentation

CodePudding user response：

according to Android Developers documentation :

• You need to upgrade your background process to foreground inorder to make it live without needing your application to be visible to the user.
• in order to change your service to foreground one, your service need to have a notification to inform the user that your music player service is working.

a simple foreground service code might look like this :

 public int onStartCommand(Intent intent, int flags, int startId) {
        super.onStartCommand(intent, flags, startId);
        Notification notification = buildStartingNotification();
        startForeground(startId, notification);
        ...
        return START_STICKY;
    }
private Notification buildStartingNotification() {
int priority  =NotificationCompat.PRIORITY_LOW;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    priority = NotificationManager.IMPORTANCE_LOW;
    createNotificationChannel(priority);
}
Notification notification =
          new Notification.Builder(this,CHANNEL_ID)
    .setContentTitle("Your_notification_title")
    .setContentText("Your_notification_description ")
    .setSmallIcon(R.drawable.icon)
    .setPriority(priority)
    .build();
}
@RequiresApi(api = Build.VERSION_CODES.O)
    private void createNotificationChannel(int priority) {
        CharSequence name = getText("Your_Channel_Name");
        String description = getString("Your_Channel_Desc");
        NotificationChannel channel = new NotificationChannel(CHANNEL_ID, name, priority);
        channel.setDescription(description);
        NotificationManager notificationManager = getSystemService(NotificationManager.class);
        notificationManager.createNotificationChannel(channel);
    }
