The steps are:

• get the audio man.
• fetch the required stream.
• call appropriate method on stream.

e.g.:

mAudioManager.adjustStreamVolume(AudioManager.STREAM_MUSIC, AudioManager.ADJUST_RAISE, AudioManager.FLAG_SHOW_UI);

• to get max vol:

  int maxVolume = mAudioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
