Broadcast receiver for GPS state?

问题

Is there a way to be notified when the GPS is switched on/off?

I noticed that when the device is switched off an then on again, getLastKnownLocation(provider) is null. So I want to save the location when the GPS is switched off to a database.

回答1:

Register a BroadcastReceiver to listen for the LocationManager's PROVIDERS_CHANGED_ACTION Intent. This will be broadcast when the GPS provider (and other providers) is enabled / disabled.
