Solution to Android CountDownTimer Skipping the Last Tick

Google's implementation of CountDownTimer in Android is a bit strange; it often skips the very last tick. I can see why they did it this way: they want to make sure that onFinish() function will be called with no delay in the case onTick() takes so much time. However, this implantation causes the last tick to skip pretty much.

Well, here is my modified version of CountDownTimer which will not skip the last tick, unless onTick() function takes too long, which it shouldn't. So, make sure that onTick() will return quickly first.

The code modification starts at line 114 below:
