Adding beep on key press in Android doesn't work

Question

In my Custom IME I want to play a BEEP sound on the key when user presses that.

I found how-do-i-access-androids-default-beep-sound , and in my SoftKeyboard.java class I added that code in :

public void onKey(int primaryCode, int[] keyCodes) {
    // play sound on keypress
    try {
        MediaPlayer mMediaPlayer = MediaPlayer.create(context, R.raw.beep);
        mMediaPlayer.prepare();
        mMediaPlayer.start();
    } catch (Exception e) {e.printStackTrace();}
}

BUT that does not work, any ideas why?

Most probably, default notification ringtone is not set (yet). Are you testing this on an emulator? — ozbek, Feb 21 '14 at 12:14
Also, please don't swallow exceptions like that, if something goes wrong, you won't know it - add e.printStackTrace() inside your catch() — Melquiades, Feb 21 '14 at 12:17
That's your problem. Test on a real device or set notification ringtone. — ozbek, Feb 21 '14 at 12:18
`that still not work` - is onKeyDown() ever called? What error are you getting? — Melquiades, Feb 21 '14 at 13:28
@Melquiades after new `Edit`, I'm getting this stack trace `02-21 18:39:09.940: E/MediaPlayer(20950): prepareAsync called in state 8` — Arshad Ali, Feb 21 '14 at 13:39
Remove mediaPlayer.prepare(), it's not needed when you create MediaPlayer with create(). — Melquiades, Feb 21 '14 at 13:44
Post an answer of what needed to be done to make it work and accept it, so that others don't have to go through these long comments to find the solution. — Melquiades, Feb 21 '14 at 13:51

I was calling mMediaPlayer.prepare() unnecessarily, as it's not needed when creating MediaPlayer with it's create() method. This is the solution which worked for me

public void onKey(int primaryCode, int[] keyCodes) {
    // play sound on keypress
    try {
        MediaPlayer mMediaPlayer = MediaPlayer.create(context, R.raw.beep);

        mMediaPlayer.start();
    } catch (Exception e) {
        e.printStackTrace();
    }
}
