The MediaPlayer class's setVolume() method only accepts scalars in the range [0.0, 1.0], but the classes deriving from AudioEffect can be used to amplify the MediaPlayer's audio session.

For example, LoudnessEnhancer amplifies samples by a gain specified in millibels (i.e. hundredths of decibels):

MediaPlayer player = new MediaPlayer();
player.setDataSource("https://www.example.org/song.mp3");
player.prepare();

// Increase amplitude by 20%.
double audioPct = 1.2;
int gainmB = (int) Math.round(Math.log10(audioPct) * 2000);
LoudnessEnhancer enhancer = new LoudnessEnhancer(player.getAudioSessionId());
enhancer.setTargetGain(gainmB);

It's unclear from the documentation, but it appeared to me that LoudnessEnhancer doesn't work properly with negative gains, so you may still need to use MediaPlayer's setVolume() method if you want to decrease the volume.

DynamicsProcessing provides multiple stages across multiple channels, including an input gain stage.

For increasing the volume of the device beyond the system volume u have to go in engineers mode.for that save below code.and paste it in number entering box In calling option it will directly redirect you to the engineers mode

      *#*#3646633#*#*

By this you can access the system settings one thing make sure that don't use this without care it may affect your system performance.
