If your alarms will be waking up the device, you need to arrange for the device to stay awake while you are doing your network I/O. See: http://github.com/commonsguy/cwac-wakeful Be careful of connectivity changes. If you woke up the device, WiFi will be off, and so if you try to access the Internet immediately, you will probably wind up with 3G (or whatever other cellular data the device uses). It is possible that your polling operation will be interrupted by WiFi turning on. I have not run experiments in this area yet myself, but based on errors I see with the Android Market client and StreamFurious Pro, that is my interpretation of what is going on. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android App Developer Books: http://commonsware.com/books -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
