How to implement GPS Status change listener

Question

In my application I am sending location update to server in each 5 minutes. For that I am using gms LocationListener. This is working fine. I am running this inside a service. It won't work if the user turned off the GPS. since it is running it in service even after turning on the GPS it will wait for completing the 5 minutes of update time. So what I want is when the user turned on the GPS it should trigger the onLocationUpdate Listener.

For that I have did as follows I have initialised GpsStatus.Listener in my service, and implemented it onStatusChange() function, but after I change the GPS status from on to off/ off to on, the function is not triggering .

Code

public class LocationUpdateService extends Service implements GpsStatus.Listener, com.google.android.gms.location.LocationListener{
    onCreate(Bundle b){
        super.onCreate();
        registerGpsStatusListener();
    }

    private void registerGpsStatusListener() {
        LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        locationManager.addGpsStatusListener(this);
    }

    @Override
    public void onGpsStatusChanged(int event) {
        switch (event) {
            case GpsStatus.GPS_EVENT_STARTED:
                Log.e(TAG, "onGpsStatusChanged started");
                break;

            case GpsStatus.GPS_EVENT_STOPPED:
                Log.e(TAG, "onGpsStatusChanged stopped");
                break;

            case GpsStatus.GPS_EVENT_FIRST_FIX:
                Log.e(TAG, "onGpsStatusChanged first fix");
                break;

            case GpsStatus.GPS_EVENT_SATELLITE_STATUS:
                Log.e(TAG, "onGpsStatusChanged status");
                break;
        }
    }

    @Override
    public void onLocationChanged(Location location) {
       //opertations
    }
}

My queries are :

1- Why the method onGpsStatusChanged() is not calling after changing the GPS status.

2- How do I get location inside onLocationChanged() method, so that I can call onLocationUpdate() method.

NOTE: Please do not recommend to use BroadcastReceiver since it requires huge code modification of my current code.

I think you are trying to know when the user switches the GPS on or off from his device. In that case you can have a look at this answer.This is the only correct and reliable way to detect GPS on/off switch (at least it is the only one that worked for me).
