What about this situation:: 1. I set an AlarmManager to wake up every 15 minutes. 2. I switch off the screen, and the phone goes to sleep in a few minutes. 3. After 15 mins, the alarm manager kicks in. 4. In the alarm manager handler code, can I take a wifi lock? Will this work? 5. Then after my job is done (in about 40 seconds) I'll release the wifi lock. Does the above stategy look okay?
