GoogleApiClient: hide GPS icon on status bar when a service is in the background

I'm using GoogleApiClient to implement a location listener service, but the GPS icon is always being displayed, even with the service in background. How to disable the GPS icon when the service is in the background?

Follow the sources below:

Activity

Please, any help is welcome.

To remove the GPS icon you need to use cached and wi-fi location settings (from memory). In your code make the following changes.

In Manifest, remove:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

In Service, change the following:

mLocationRequest.setInterval(10000L);
mLocationRequest.setFastestInterval(5000L);
// Do NOT use LocationRequest.PRIORITY_HIGH_ACCURACY here
// Instead use one of the other option.
mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
//mLocationRequest.setPriority(LocationRequest.PRIORITY_LOW_POWER);
//mLocationRequest.setPriority(LocationRequest.PRIORITY_NO_POWER);
// Remove setSmallestDisplacement() as it should not be used
// unless you are using a GPS / PRIORITY_HIGH_ACCURACY
//mLocationRequest.setSmallestDisplacement(DISPLACEMENT);

Pretty sure this is will remove the GPS icon but you will also only get the FusedLocationApi.getLastLocation() values when the onConnected() method is called (very possible this will be low accuracy).

The onLocationChanged() method may never trigger until another application makes a location request at a higher priority or with more accuracy.
