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.
