You will need this:

    private void playNextMusic() {
    Intent i = new Intent(Intent.ACTION_MEDIA_BUTTON);
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_NEXT));
    sendOrderedBroadcast(i, null);

    i = new Intent(Intent.ACTION_MEDIA_BUTTON);
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_NEXT));
    sendOrderedBroadcast(i, null);

    playPlayMusic();
}

private void playPreviousMusic() {
    Intent i = new Intent(Intent.ACTION_MEDIA_BUTTON);
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_PREVIOUS));
    sendOrderedBroadcast(i, null);

    i = new Intent(Intent.ACTION_MEDIA_BUTTON);
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_PREVIOUS));
    sendOrderedBroadcast(i, null);

    playPlayMusic();
}

private void playPauseMusic() {
    Intent i = new Intent(Intent.ACTION_MEDIA_BUTTON);
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_PAUSE));
    sendOrderedBroadcast(i, null);

    i = new Intent(Intent.ACTION_MEDIA_BUTTON);
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_PAUSE));
    sendOrderedBroadcast(i, null);
}

private void playPlayMusic() {
