Switching between earpiece and speakerphone on button press

Question

I am trying to play audio from both the speakerphone and earpiece by having a button toggle between the two. The problem is that I am trying to default the audio to play from the earpiece, but nothing comes out. Then when I press the button to toggle to speakerphone, still no audio plays. I am playing from a local raw file.

I have android.permission.MODIFY_AUDIO_SETTINGS in the Manifest as well.

Here is my code:

@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);

    context = getActivity().getBaseContext();

    am = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);

    am.setMode(AudioManager.MODE_IN_CALL);
    am.setSpeakerphoneOn(false);
    am.setBluetoothScoOn(true);
    speakerON = false;
}

@Override
public void onClick(View v)
{               
    switch (v.getId())
    {

        case R.id.buttonSpeaker:
            if(!speakerON)//speaker off
            {
                speakerON = true;
                am.setMode(AudioManager.MODE_NORMAL);
                am.setSpeakerphoneOn(true);
                am.setBluetoothScoOn(false); 
                speaker.setCompoundDrawablesWithIntrinsicBounds(android.R.drawable.ic_lock_silent_mode_off, 0, 0, 0);
            }
            else
            {
                speakerON = false;
                am.setMode(AudioManager.MODE_IN_CALL);
                am.setSpeakerphoneOn(false);
                am.setBluetoothScoOn(true);
                speaker.setCompoundDrawablesWithIntrinsicBounds(android.R.drawable.ic_lock_silent_mode, 0, 0, 0);
            }

            break;

    }
}

Here is how I am setting up the MediaPlayer:

mediaPlayer = MediaPlayer.create(getActivity().getBaseContext(), R.raw.test_message);
mediaPlayer.setAudioStreamType(AudioManager.STREAM_VOICE_CALL);
mediaPlayer.start();

It turns out that I had set the mode wrong.

Here is the updated media player:

mediaPlayer = MediaPlayer.create(getActivity().getBaseContext(), R.raw.test_message);
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.start();

And then I set the mode for the audio manager to :

context = getActivity().getBaseContext();

am = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);        
am.setMode(AudioManager.MODE_IN_CALL);
am.setSpeakerphoneOn(false);

And then it worked. So make sure that the media player and audio manager are in the same mode.

According to the javadocs the call to AudioManager.setMode(..) only takes the following constants: MODE_NORMAL, MODE_RINGTONE, MODE_IN_CALL or MODE_IN_COMMUNICATION. – Ivan Dec 01 '12 at 21:33

basically, AudioManager.STREAM_MUSIC and MODE_IN_CALL are the same value. It should have been MODE_IN_CALL. It works in the above case because I believe both have the value "3". However, one should be using MODE_IN_CALL as Ivan points out. – Geebs Feb 20 '13 at 13:20
Hello Mike I have to switch between speaker mode and earpiece mode on click of a button while playing a mp3 stored on sdcard. I tried your above code but am not able to do it. Can you please elaborate the click handling? – seema Mar 20 '14 at 12:25
do we need to prepare mediaplayer again after switching audio manager mode? – seema Mar 20 '14 at 12:27
I honestly may not be the best source of help. I have moved on to other projects that are not Windows phone. I wish you the best of luck. – BC2 Apr 30 '14 at 22:04
This works. media player and audio manager both should be in the same mode. – Amit Thaper Nov 25 '16 at 10:13
