I recently began working with Java and am exploring Android development. I was trying to port over one of the Java programs I made, but I am having some difficulty with getting the java Timer to function the same way in Android. I read through a number of posts and they, for the most part, indicated that it would be better to use the Handler class in android as opposed to Timer.

This was my timer in Java:

```
playTimer = new Timer(1000/model.getFPS(), new ActionListener() {
    public void actionPerformed(ActionEvent evt) {
        // do something
        ...
        if( finished everything ) playTimer.stop();
    }
});

```

And once a certain button was clicked, I would simply run "playTimer.start()" to start it.

As you can see, I had it set up so that the user could set the FPS they wanted (by simply setting the first parameter of the Timer class to 1000/model.getFPS()).

Now I've tried to do something similar in Android using handlers, but I am having some difficulty. It appears that the Handler ticks are not firing at the proper intervals. It seems that they are quite slow compared to what I need it to be. This is what I did in android so far:

```
public void startTimer() {
    playHandler = new Handler();
    startTime = System.currentTimeMillis();
    playHandler.removeCallbacks(updateTimeTask);
    playHandler.postDelayed(updateTimeTask, 0);
}

private Runnable updateTimeTask = new Runnable() {
    public void run() { 
        // do something
        ...

        if( finished everything ) playHander.cancel();
        else {
            playHandler.postDelayed(updateTimeTask, 1000/model.getFPS());
        }
    }
};

```

Excuse the semi-pseudocode. Can anyone shed any light? Thanks guys.
