Error is on this line : 

errorFragment.show(getSupportFragmentManager(), LocationUtils.APPTAG);

The code : 

/**
     * Verify that Google Play services is available before making a request.
     *
     * @return true if Google Play services is available, otherwise false
     */
    private boolean servicesConnected() {

        // Check that Google Play services is available
        int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);

        // If Google Play services is available
        if (ConnectionResult.SUCCESS == resultCode) {
            // In debug mode, log the status
            Log.d(LocationUtils.APPTAG, getString(R.string.play_services_available));

            // Continue
            return true;
        // Google Play services was not available for some reason
        } else {
            // Display an error dialog
            Dialog dialog = GooglePlayServicesUtil.getErrorDialog(resultCode, this, 0);
            if (dialog != null) {
                ErrorDialogFragment errorFragment = new ErrorDialogFragment();
                errorFragment.setDialog(dialog);
                errorFragment.show(getSupportFragmentManager(), LocationUtils.APPTAG);
            }
            return false;
        }
    }

Thx !

Normally, the above code is called inside onStart/OnResume method or after these methods, not inside onStop/onSaveInstance. You are trying to do some operation after activity is getting killed. Perform serivcesConnected call before onStop/finish/saveInstances method call.
