Question

I have done the app like talking tom to repeat the voice again. But the playback sound is very low.So please tell me how to increase the mp3 sound manually.

Thanks in advance

Answer 1

You can use AudioManager to increase the volume to 100 percent.

AudioManager am = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
int maxVol = am.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
am.setStreamVolume(AudioManager.STREAM_MUSIC, maxVol, AudioManager.FLAG_SHOW_UI);

You will need the Audio Settings permission.

<uses-permission
     android:name="android.permission.MODIFY_AUDIO_SETTINGS"/>

I will say, though, that you probably don’t want to do this. The user knows what volume they want the playback to be at, and they will set it where they want it to be.
