How can I reschedule a timer. I have tried to cancel the timer/timertask and and schedule it again using a method. But its showing an exception error:
Exception errorjava.lang.IllegalStateException: TimerTask is scheduled already
Code I have used it :
private Timer timer = new Timer("alertTimer",true); public void reScheduleTimer(int duration) { timer.cancel(); timer.schedule(timerTask, 1000L, duration * 1000L); }

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:
