Question

In a game I am developing I want to create a delay. The delay am I makeing is using a handler with this code:

handler.postDelayed(new Runnable() {
        public void run() {
               animationDrawable.start();

                }
        },theDelay);

The problem is that I got a pause button that is going to make everything stop, and not do anything until you resume again. For now it is running even though the gameplay is paused. I got a boolean that is changed when I want to pause the activity.

I have searched for solutions using a Thread, TimerTask and Handler, but for everyone of these I have seen warning about that non of these is safe to use.

How can I pause and resume this “countdown” in a secure way, and without haveing to start it all over again when resuming?

How can I pause and resume this “countdown” in a secure way, and without having to start it all over again when resuming?

1. save the start time when you start the handler like this – startTime = System.currentTimeMillis();
2. inside the onPause save that time pauseTime = System.currentTimeMillis(); and cancel the hendler
3. inside onResume recreate the event with the pauseTime - startTime
