Code:
public class SMH extends Activity { public void onCreate(Bundle b) { super.onCreate(b); setContentView(R.layou
So I think I went a little over board because my timer runs in its own thread instead of using postDelay handlers, though it always posts back to the thread it was created in. I also knew that I only cared about seconds so its simplified around that idea. It also lets you cancel it and restart it. I do not have pausing built in because that's not in my needs.
