Define "condition". The OP was inquiring about time, which I would not call a "condition". > I was reading the blog on Screebl, it seemed like > with the Location support they can activate based on the location or other > conditions of the device.

The key to battery life is that you want the phone in sleep mode. Hence, depending on how the service is "waiting", it may need to force the device to stay awake, which is awful for battery life. If you are interested in this subject, you really should watch Jeff Sharkey's "Coding for Life...Battery Life, That Is" presentation from the 2009 Google I/O conference. There's a YouTube video of it out there. > I've not looked into the > Location api, but it sounded like Location would send out a message that a > service could listen for.. as if you could say "when the location of this > device is 'around' this location.. call me". Something like that? That certainly exists, but I have not experimented with it recently, let alone with the device in sleep mode. Again, the OP was inquiring about timers, so my reply was focused on timers. -- Mark Murphy (a Commons Guy) http://commonsware.com Android App Developer Books: http://commonsware.com/books.html
