Play Sound Through Earpiece When Using Mediaplayer

I am playing voicemail recordings in my app. The way I currently have it set up, it plays the voicemail through the speakerphone. What is the best way to be able to toggle between

Solution 1:

You need to set audio manager mode too. and then using audiomgr.setSpeakerphoneOn(false) api you can toggle.

audiomgr = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audiomgr.setMode(AudioManager.STREAM_MUSIC);
audiomgr.setSpeakerphoneOn(false);
