How with broadcast receiver should I subscribe to listen for location services change

Question

I am working in an app that manages wifi connections, I have the problem that in android 6.0 the wifi scanning is off when the location services are turned off by the user.

What I want is to know if there is an action to which I can subscribe to listen when the user turns off and on the location services. I have searched in Android documentation and there are two possible actions, but I am not sure which one to use.

The actions are

android.location.PROVIDERS_CHANGED

android.location.MODE_CHANGED

The Documentation is not helping me.

Answer 1

This is useful when user want to trigger any action on turn On/Off location provides

You should add this action in manifest

<action android:name="android.location.PROVIDERS_CHANGED" />

and after add this action you can trigger your broadcast receiver

<receiver android:name=".GpsLocationReceiver">
    <intent-filter>
        <action android:name="android.location.PROVIDERS_CHANGED" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>

And in your BroadcastReceiver class you have to implement LocationListener in that class which is given following below..

  public class GpsLocationReceiver extends BroadcastReceiver {        
        @Override
        public void onReceive(Context context, Intent intent) {
            if (intent.getAction().matches("android.location.PROVIDERS_CHANGED")) {
                Toast.makeText(context, "in android.location.PROVIDERS_CHANGED",
                Toast.LENGTH_SHORT).show();
           LocationManager locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
    if( !locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER) ) {
       //NO GPS
    }else{
//Gps is on
     }
            }
        }
    }
