Reschedule timer in android

If you see the documentation on Timer.cancel() you’ll see this:

“Cancels the Timer and all scheduled tasks. If there is a currently running task it is not affected. No more tasks may be scheduled on this Timer. Subsequent calls do nothing.”

You’ll need to initialize a new Timer when you are rescheduling:


public void reScheduleTimer(int duration) {
  timer = new Timer("alertTimer",true);
  timerTask = new MyTimerTask();
  timer.schedule(timerTask, 1000L, duration * 1000L);

private class MyTimerTask extends TimerTask {
  public void run() {
    // Do stuff
