The GPS position is changing (slightly) all of the time, so no it won't wake up the phone just for that. You need to be really, really careful about how you do this in the background so you don't kill the user's device. First, if you are going to continually monitor the GPS... don't. You can expect battery life of 5 hours or less if you do that. So you need to set the AlarmManager to wake you up at some slow interval (not less than every 10 seconds) at which point you sample the current position and go back to sleep. You'll want to play around with this on a real device to tune it to have good performance, and definitely want to let the user know this is happening and allow them to stop your background monitoring. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
