Question

I have a doubt with media audio.

My app haves an Activity which loads a SurfaceView class and I cannot get to modify media audio.

I saw the following statement :

    this.setVolumeControlStream(AudioManager.STREAM_MUSIC);

but it isn’t works.

¿Someone could help me?

Thanks!

EDIT SOME CODE:

In my first Activity for example:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
//Other things
}

I’m trying to modify multimedia audio stream in runtime, but i don’t know how to do it

Answer 1

Okay, try this. I managed to do it on my SurfaceView.
In your Activity you have:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    gameView = new GameView(this, GameActivity.this);
    setContentView(gameView); 
}

Then in your SurfaceView you can do the followin in the constructor:

public GameView(Context context, Activity activity) {
    super(context);
    activity.setVolumeControlStream(AudioManager.STREAM_MUSIC);
}
