You're most likely seeing an issue because a Service is not guaranteed to run when triggered by an alarm, due to power save. If your device is on battery and idle when that alarm goes off, it will not trigger until the next time the device is full on or on AC power. You'll need to use a BroadcastReceiver which holds a wake lock which is then released by the Service when it is done. The WakefulBroadcastReceiver makes this a little easier to handle.
