How to execute a background task periodically in Android?

I'm making an app that starts a Service that sends SMS message periodically under specific conditions. It all works, but I have problems to run the job (check conditions + message sending) periodically every minute when the phone is in "standby" (display turned off). With screen on it all works without problems.

I tried using java Timer and TimerTask, but when the screen is off nothing works and when I turn it on, all skipped task are executed in a row (for example, if I turn off the screen at 20:00 and turn on it at 20:30, TimerTask is executed 30 times at 20:30).

I tried also with Handler using Handler.postDelayed method. In this case nothing is done, and when I turn on the screen skipped task are not executed.

So, how can I run a Runnable every minute also when device screen is off???
