Answer 1

Try instead of Timer class ScheduledFuture
This helped for me to resolve all problems with timer tasks
Good luck!

private ScheduledFuture mytimer;

//...

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    ScheduledExecutorService timer = Executors.newScheduledThreadPool(1);
    mytimer = timer.scheduleWithFixedDelay(new TimerTask() {
        @Override
        public void run() {
            //...
        }
    }, 0, interval, TimeUnit.MILLISECONDS);
    return super.onStartCommand(intent, flags, startId);
}

//...

@Override
public void onDestroy() {
    super.onDestroy();
    if (mytimer != null) {
        mytimer.cancel(true);
    }
    //...
}

It looks like you're using the timer wrong. If you want to have it recur, you need to specify an initial delay as the second argument, and an interval as the third. Timer.schedule(timertask, initial delay, interval between recurrences);

Note: I'm talking about your call to myTimer.schedule(object, interval);
