Rather than maintaining a thread, I recommend just using a CountDownTimer: http://developer.android.com/reference/android/os/CountDownTimer.html
Of course that still leaves your pause problem. One way to do it is: 1) when the user starts, kick off the CountDownTimer and store the start time, say in a variable startTime. 2) if the user pauses, then cancel the CountDownTimer, and store the time elapsed so far (current time - startTime) in another variable, say timeElapsedSoFar. 3) when the user resumes, set a new CountDownTimer, which is shorter than the original by timeElapsedSoFar. I skipped a few details for the sake of brevity, but I hope you get the idea.
