Java / Android Programming - Loop FAIL

Question

I am using a while loop with a timer. The thing is that the timer is not used in every loop. It is used only the first time. After the first time the statements included inside

Answer 1

The TimerTask kicks off a new Thread and then the loop proceeds as normal.

The execution of the thread does not cause a delay to the execution of the code in your loop.

Answer 2

You're scheduling 10 TimerTasks to execute after an hour, at the same time. So all 10 tasks are being executed after 1 hour, which makes it seem like 1 execute since all the Toast messages display at the same time. To schedule tasks at a fixed delay, with the first task starting in 1 hour, use this method:

Timer t = new Timer();
t.schedule(task, 3600000, 3600000);

This will execute until you call t.cancel().

Answer 3

It's because you're queueing up 10 toasts all to execute in one hour. Each iteration of your loop takes only a fraction of a millisecond or maybe a tad bit more than that. To enqueue them properly, you could do 3600000 * count instead of 3600000 each time.

This is a terrible way to do it though. You should use AlarmManager for stuff like this.
