Can't get location without wifi

Whatever I do, I just can't get current location without wifi enabled. This code works only when wifi is enabled:

if(locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER))
    provider = LocationManager.GPS_PROVIDER;
else if(locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER))
    provider = LocationManager.NETWORK_PROVIDER;
else if(locationManager.isProviderEnabled(LocationManager.PASSIVE_PROVIDER))
    provider = LocationManager.PASSIVE_PROVIDER;

Location location = locationManager.getLastKnownLocation(provider);

When wifi is disabled, location is null.

And the following code never works (even if wifi is enabled):

protected synchronized void buildGoogleApiClient() {
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(LocationServices.API)
            .build();
}

in onCreate():

buildGoogleApiClient();

in onStart():

mGoogleApiClient.connect();

And here's onConnected():

@Override
public void onConnected(Bundle connectionHint) {
    mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);

    if(mLastLocation == null)
    {
        disableButtons();
    }
    else
    {
        String userLocation = FindLocation.getLocatoinName(mLastLocation);
        userLocationDetails = new LocationStruct(mLastLocation.getLatitude(), mLastLocation.getLongitude(), userLocation);
    }
}

Inside onConnected(), mLastLocation is always null.

I tried on 2 phones: Lenovo A820 API 16 and Samsung Galaxy S4 API 19. Same result on both phones.

You cannot rely on Last Known Location to always be available. In your onConnected() you're only checking for the last known location.

You have to create a LocationRequest in your onConnected()

mLocationRequest = LocationRequest.create()
            .setPriority(locationPriority) // LocationRequest.PRIORITY_HIGH_ACCURACY
            .setInterval(10 * 1000)        // 10 * 1000 10 seconds, in milliseconds
            .setFastestInterval(1 * 1000);

Then you have to request location updates:

LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);

You'll then get Location in onLocationChanged(Location location)
