Question

I am working on an alarm feature for my application where, at a certain time, an alarm Activity is started, which subsequently starts either a vibration or a ringtone. The problem I’ve run into is that the vibration or ringtone is not stopped if the user presses the Home button.

I have overriden onKeyDown so that the alarm is stopped when a button is pressed, but that does not intercept the Home button code:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (mVibrator != null)
        mVibrator.cancel();
    if (mPlayer != null) {
        mPlayer.stop();
        mPlayer.release();
    }
    return super.onKeyDown(keyCode, event);
}

How can I go about stopping the vibration/ringtone when this occurs?

Answer 1

I’d suggest stopping the alarm in onPause(). That gets called whenever another application comes to the foreground (including the home screen).
