Should I use AlarmManager or Handler?

Question

I\'m writing an app that constantly polls the device\'s sensors and every so often should write down some statistics to a file. This could be as fast as once a second or as

I'd say that it depends on the polling interval. I guess it's quite low in your case (around a few secs), so you should go the Handler way, or by using the Timer class.

AlarmManger is a much higher level service and it involves a larger overhead to handle this use case. When an alarm triggers, you need to handle it with BroadcastReceivers. This means that every time you handle one of these alarm, you needs to register listeners for the sensors you're interested in, which is immensely inefficient imho.
