background music doesn't stop if app is onStop Android
I have created a service to play music through my activities. I Have 2 activities and a splashScreen. I start the service from the first acitivity and by clicking some items I go to the second activity. The music is played properly but when I put my app in background or I lock my phone or I'm in another app I still hear the sound. I cannot put stopService in onStop because if I go to my second activity, the music will stop.
Here's my service music class :
public class BackgroundMusicService extends Service {
MediaPlayer player;
public IBinder onBind(Intent arg0) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
player = MediaPlayer.create(this, R.raw.game_music);
player.setLooping(true);
player.setVolume(10, 10);
player.start();
}
public int onStartCommand(Intent intent, int flags, int startId) {
player.start();
return 1;
}
@Override
public void onDestroy() {
player.stop();
player.release();
}
@Override
public void onLowMemory() {
}
}
and :
public class Activity1 extends AppCompatActivity implements View.OnClickListener{
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_1);
Intent backgSound = new Intent(Activity1.this, BackgroundMusicService.class);
startService(backgSound);
Button b1 = (Button) findViewById(R.id.b1);
b1.setOnClickListener(this);
}
@Override
public void onDestroy() {
super.onDestroy();
Intent backgSound = new Intent(Activity1.this, BackgroundMusicService.class);
stopService(backgSound);
}
@Override
public void onClick(View v) {
startActivity(new Intent(this,Activity2.class);
}
And the second activity is just a view (for test).
How could I keep the sound over these 2 activites and stop it when my app is in background or my phone is locked.
I've tried to stopService in onStop then startService in onResume, but it does not work between activities.
Judging by what you want you need a more fine grained control over the starting and stopping of your MediaPlayer object. An easy solution would be to add intent-filters and actions like so:
public class BackgroundMusicService extends Service {
public static final String ACTION_START_MUSIC = "package_name.action_start_music";
public static final String ACTION_STOP_MUSIC = "package_name.action_stop";
private MediaPlayer player;
public IBinder onBind(Intent arg0) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
player = MediaPlayer.create(this, R.raw.game_music);
player.setLooping(true);
player.setVolume(10, 10);
}
public int onStartCommand(Intent intent, int flags, int startId) {
if(intent.getAction() != null){
switch (intent.getAction()){
case ACTION_START_MUSIC :
if(!player.isPlaying()){
player.start();
}
break;
case ACTION_STOP_MUSIC :
if(player.isPlaying()) {
player.stop();
}
break;
default: break;
}
}
return START_STICKY;
}
@Override
public void onDestroy() {
player.release();
}
@Override
public void onLowMemory() {
}
}
Update your manifest :
<service android:name=".BackgroundMusicService"
android:exported="false">
<intent-filter>
<action android:name="package_name.action_start_music" />
<action android:name="package_name.action_stop" />
</intent-filter>
</service>
To use:
startService(new Intent(BackgroundMusicService.ACTION_START_MUSIC));
startService(new Intent(BackgroundMusicService.ACTION_STOP_MUSIC));
