[android help] Is it possible to get a notification when any location provider is enabled/disabled and ascertain what action occurred?

I wish to receive a notification when the user enables or disabled either Network or GPS locations, and importantly I wish to know which one they have changed and how. I have a broadcast receiver for the android.location.PROVIDERS_CHANGED broadcast intent and this is receiving the correct broadcast.

I now need to try and determine what action has occurred i.e. enable or disable and which provider has been changed. I know that I could keep the state of each provider and then when I receive notification that they have changed then I could work out what has changed, I am looking for a more "standard" method of doing this. The broadcast intent does not seem to have any extras to indicate which provider has changed.

This is the code I have currently.

    public class LocationProviderChangedReceiver extends BroadcastReceiver {
    private final static String TAG = "LocationProviderChangedReceiver";

    @Override
    public void onReceive(Context context, Intent intent) {
      if (intent.getAction().matches("android.location.PROVIDERS_CHANGED"))
      {
        Log.i(TAG,"Location Providers changed");
        Bundle bundle = intent.getExtras();
        if (bundle == null) {
          Log.d(TAG, "No extras data");
         } else {
           Log.d(TAG, "Bundle received of size " + bundle.size);
         } 
      }
    }
  }

And this is a small extract from my Manifest

  
  

      android:name=".LocationProviderChangedReceiver"
    android:exported="false">
    
      
      
    
  

Is anyone aware of any mechanism by which I can determine what state has changed without maintaining my own state variables.

In an ideal world I would monitor for changes constantly but only listen for location changes occasionally. I would like to avoid constantly monitoring for location changes.
