title: how to wakeup android phone from sleep?
body: <p>How to wakeup android phone from sleep (suspend to mem) programmably? I don't want to acquire any wakelock, which means the phone goes into "real" sleep with the cpu disabled. I guess I can use some kind of RTC (real time clock) mechanism?</p>
  
  <p>Does anyone have any examples?</p>
  
  <p>Thanks.</p>
