How do you get/set media volume (not ringtone volume) in Android?

Is there a way to get/set media volume? I have tried the following:

AudioManager audio = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
int currentVolume = audio.getStreamVolume(AudioManager.STREAM_RING);

but it returns the ringtone volume.

private AudioManager audio;

Inside onCreate:

audio = (AudioManager) getSystemService(Context.AUDIO_SERVICE);

Override onKeyDown:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    switch (keyCode) {
    case KeyEvent.KEYCODE_VOLUME_UP:
        audio.adjustStreamVolume(AudioManager.STREAM_MUSIC,
                AudioManager.ADJUST_RAISE, AudioManager.FLAG_SHOW_UI);
        return true;
    case KeyEvent.KEYCODE_VOLUME_DOWN:
        audio.adjustStreamVolume(AudioManager.STREAM_MUSIC,
                AudioManager.ADJUST_LOWER, AudioManager.FLAG_SHOW_UI);
        return true;
    default:
        return false;
    }
}

Instead of AudioManager.STREAM_RING you shoul use AudioManager.STREAM_MUSIC This question has already discussed here.

Have a try with this:

setVolumeControlStream(AudioManager.STREAM_MUSIC);

AudioManager audio = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
int currentVolume = audio.getStreamVolume(AudioManager.STREAM_MUSIC);
int maxVolume = audio.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
float percent = 0.7f;
int seventyVolume = (int) (maxVolume*percent);
audio.setStreamVolume(AudioManager.STREAM_MUSIC, seventyVolume, 0);
	

You can set your activity to use a specific volume. In your activity, use one of the following:

this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
this.setVolumeControlStream(AudioManager.STREAM_RING);  
this.setVolumeControlStream(AudioManager.STREAM_ALARM);  
this.setVolumeControlStream(AudioManager.STREAM_NOTIFICATION);  
this.setVolumeControlStream(AudioManager.STREAM_SYSTEM);  
this.setVolumeControlStream(AudioManager.STREAM_VOICECALL); 

If you happen to have a volume bar that you want to adjust –similar to what you see on iPhone's iPod app– here's how.

	@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {

	switch (keyCode) {
	case KeyEvent.KEYCODE_VOLUME_UP:
		audioManager.adjustStreamVolume(AudioManager.STREAM_MUSIC, AudioManager.ADJUST_RAISE, AudioManager.FLAG_SHOW_UI);
		//Raise the Volume Bar on the Screen
		volumeControl.setProgress( audioManager.getStreamVolume(AudioManager.STREAM_MUSIC)
				+ AudioManager.ADJUST_RAISE);
		return true;
	case KeyEvent.KEYCODE_VOLUME_DOWN:
		//Adjust the Volume
		audioManager.adjustStreamVolume(AudioManager.STREAM_MUSIC, AudioManager.ADJUST_LOWER, AudioManager.FLAG_SHOW_UI);
		//Lower the VOlume Bar on the Screen
		volumeControl.setProgress(audioManager
				.getStreamVolume(AudioManager.STREAM_MUSIC)
				+ AudioManager.ADJUST_LOWER);
		return true;
	default:
		return false;
	}

The following code will set the media stream volume to max:

AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC,
    audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC),
    AudioManager.FLAG_SHOW_UI);

To set volume to 0

AudioManager audioManager;
audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 0, 0);

To set volume to full

AudioManager audioManager;
audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 20, 0);

the volume can be adjusted by changing the index value between 0 and 20
