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);
    }
    //...
}
