Re: [android-developers] Broadcast Receiver registering Location Listener problem

I know the receiver is transient, and has a short lifespan. Once the receiver dies, will my listener still continue to be registered, or do I have to write a (perpetual) service to register the listener? Ideally, neither. If all goes well, on Friday I'll be releasing a LocationPoller service that will handle this scenario, though I don't recommend trying to get locations already at boot time (wait a couple of minutes via AlarmManager). public class LocationReceiver extends BroadcastReceiver { �...@override public void onReceive(Context context, Intent intent) { Log.d(PreciseLocator, ===In Receiver, starting listener); LocationManager lm = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE); lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000L, 500.0f, new DroidLocationListener()); } .. This will leak the listener, until such time as Android gets rid of or recycles your process. This is not a good strategy. Can I have just a receiver, without an activity in the manifest? Yes, though Android Market users tend to greatly dislike this. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy _The Busy Coder's Guide to *Advanced* Android Development_ Version 1.9 Available! -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Broadcast Receiver registering Location Listener problem
Mark, Once again, thanks for an informative response. I will try the AlarmManager route, while I eagerly await your service. On the manifest question, everytime I load my application on the emulator, I get a No Launcher activity found! on the console. Is this normal? Thanks again.
