I have a service which has one Timer. I call timer.scheduleAtFixedRate() in the onStart() callback method. But I have to alter the timer interval depending on the value of a variable. I found no function for timer to alter its interval. So I thought to cancel the timer and re-schedule when that condition is met. But I am checking the condition with in the timerTask itself. So when I tried to cancel the timer in the TimerTask, it throws IllegalStateException. Can anybody give me some solution?

推荐答案

Netiher Timer.cancel（）也不 TimerTask.cancel（）抛出 IllegalStateException异常。当您尝试安排一个任务时引发一个取消定时器。

Netiher Timer.cancel() nor TimerTask.cancel() throws IllegalStateException. That is thrown when you try to schedule a task on a cancelled Timer.

解决方法：不要取消定时;取消的TimerTask 。

Solution: don't cancel the Timer; cancel the TimerTask.
