LocationServices permission problem in "I Am Here" app.

I have a problem in "i Am Here" app which i made following this guide.

In this onConnected() method: 

@Override
    public void onConnected(@Nullable Bundle bundle) {
        Log.i(TAG, "Location services connected.");
        Location location = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
        if (location == null) {
             LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
        } else {
             handleNewLocation(location);
        }
    }

I have an error which says 'Call requires permission which can be rejected by user...' I found a way to modify code:

if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION)
                == PackageManager.PERMISSION_GRANTED) {
       location = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
}

But app is not working. I guess I have to add an else statement to handle somehow the case when permission is not granted.

Would you happen to be on API 23 (Marshmallow)? If you are, then you'll also need to explicitly request that permission. https://developer.android.com/training/permissions/requesting.html

According to this link I should only ask for permission in onConnected() method and I should handle all location operations in onRequestPermissionsResult() method ? And it would still work on devices with lower API ?
