Setting the Android System Volume

Question

I am writing an application which handles the following:

1. Silent - Makes the phone volume silent
2. Low - Makes the phone volume 1 point above the silent<

Answer 1

Add this in onCreate() method of your code and then play around with the 0 value to increase or decrease the volume where 0 means OFF.

AudioManager mgr=null;

mgr=(AudioManager)getSystemService(Context.AUDIO_SERVICE);
mgr.setStreamVolume(AudioManager.STREAM_MUSIC, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
mgr.setStreamVolume(AudioManager.STREAM_RING, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
mgr.setStreamVolume(AudioManager.STREAM_ALARM, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
mgr.setStreamVolume(AudioManager.STREAM_SYSTEM, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
mgr.setStreamVolume(AudioManager.STREAM_NOTIFICATION, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
