Android MediaPlayer volume is very low ( already adjusted Volume )

Question

I m using the MediaPlayer to play one of the internal alarm ringtone. i m using the setVolume(1.0f, 1.0f) to maximize the volume when the ringtone is played. but the ringtone doesn't play full volume ( when I compare it to playing the ringtone separately or through the built it android alarm)

here is my code

mediaPlayer.setDataSource(context, ringtoneUri);
mediaPlayer.setLooping(looping);
mediaPlayer.setVolume(1.0f, 1.0f);
mediaPlayer.prepare();
mediaPlayer.start();

I added the following permission android.permission.MODIFY_AUDIO_SETTINGS ( not sure if this is needed )

Any Idea why the mediaPlayer still won't play the sound at maximum?

Solution 1

Here is the solution I found.

AudioManager amanager = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE);
int maxVolume = amanager.getStreamMaxVolume(AudioManager.STREAM_ALARM);
amanager.setStreamVolume(AudioManager.STREAM_ALARM, maxVolume, 0);

MediaPlayer mediaPlayer= new MediaPlayer();

mediaPlayer.setAudioStreamType(AudioManager.STREAM_ALARM); // this is important.

mediaPlayer.setDataSource(context, ringtoneUri);
mediaPlayer.setLooping(looping);  
mediaPlayer.prepare();
mediaPlayer.start();

Solution 2

I encountered the same issue, and then noticed this this in the MediaPlayer documentation:

While in the Prepared state, properties such as audio/sound volume, screenOnWhilePlaying, looping can be adjusted by invoking the corresponding set methods.

Calling setVolume after calling prepare fixes this, so that audio is played at max volume. Actually, according to the docs I just quoted, you should call setLooping after prepare as well:

mediaPlayer.setDataSource(context, ringtoneUri);
mediaPlayer.prepare();
mediaPlayer.setLooping(looping);
mediaPlayer.setVolume(1.0f, 1.0f);
mediaPlayer.start();
