Android Bluetooth Earpiece Volume

Question

how can I programmatically set the system volume for voice call when using a bluetooth earpiece?

Using this:

mAudioManager.setStreamVolume(AudioManag         


        

Answer 1

I also got in same problem and found out that, Android is using int 6 for bluetooth volume and not documented.

Just use 6 instead of AudioManager.STREAM_VOICE_CALL and try, It should work

Answer 2

This will work.

mAudioManager.setStreamVolume(6, value, 0 /* flags, 0 = no flags */);
