Stop a TimerTask without stopping the Timer

I have a Timer and I schedule a task for it at a certain fixed rate, using the method scheduleAtFixedRate. The problem is that after some actions, i want to finish/cancel this task that was scheduled before.

I know that i can use .cancel() or .purge() but that will cancel/finish my timer, which is something that i don't want to. I just want to finish the task.

Does any of you know how to do this ?

This is my code (I have the Timer created as a field of the class)

receiveTimer.scheduleAtFixedRate(new TimerTask() {
        @Override
        public void run() {

            int fileSize=(int)fileSizeToReceive;
            int actual= totalReceived;

            ((Notification.Builder) mBuilderReceive).setContentText("Receiving  "+actualNameToReceive);
            ((Notification.Builder) mBuilderReceive).setProgress(fileSize, actual, false);
            mNotifyManager.notify(id, ((Notification.Builder) mBuilderReceive).getNotification());
        }
    },0,500);//delay, interval

Just hold a reference to your TimerTask so you can call cancel() on it whenever you'd like.

Calling cancel() on the TimerTask will not stop the Timer.

For example, declare your task:

TimerTask task;

Initialize and schedule it:

task = new TimerTask() {
    @Override
    public void run() {
        int fileSize=(int)fileSizeToReceive;
        int actual= totalReceived;

        ((Notification.Builder) mBuilderReceive)
            .setContentText("Receiving  "+actualNameToReceive);
        ((Notification.Builder) mBuilderReceiver)
            .setProgress(fileSize, actual, false);
        mNotifyManager.notify(id, ((Notification.Builder) mBuilderReceive)
            .getNotification());
    }
};

receiveTimer.scheduleAtFixedRate(task, 0, 500);

To stop it, you just have to call cancel() on the task instance:

task.cancel();

boolean isStop = false;

 receiveTimer.scheduleAtFixedRate(new TimerTask() {
        @Override
         public void run() {

          if(!isStop){

            int fileSize=(int)fileSizeToReceive;
            int actual= totalReceived;

            ((Notification.Builder) mBuilderReceive).setContentText("Receiving  "+actualNameToReceive);
            ((Notification.Builder) mBuilderReceive).setProgress(fileSize, actual, false);
            mNotifyManager.notify(id, ((Notification.Builder) mBuilderReceive).getNotification());
          }
        }
    },0,500);//delay, interval

when you dont want execute the code set isStop = true
