Changing Location Settings

I am working on an application that needs user's location. I cannot get the location if the user turn the location setting off. Therefore, I follow the android training to prompt the location setting dialog to let the user turn the location setting on: https://developer.android.com/training/location/change-location-settings.html

public static void settingsRequest(final Activity activity) {
        LocationRequest mLocationRequest = new LocationRequest();
        mLocationRequest.setInterval(10000);
        mLocationRequest.setFastestInterval(5000);
        mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

        LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
                .addLocationRequest(mLocationRequest);
        builder.setAlwaysShow(true);

        SettingsClient client = LocationServices.getSettingsClient(activity);
        Task<LocationSettingsResponse> task = client.checkLocationSettings(builder.build());

        task.addOnSuccessListener(activity, new OnSuccessListener<LocationSettingsResponse>() {
            @Override
            public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
                // All location settings are satisfied. The client can initialize
                // location requests here.
                // ...
            }
        });

        task.addOnFailureListener(activity, new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                int statusCode = ((ApiException) e).getStatusCode();
                switch (statusCode) {
                    case CommonStatusCodes.RESOLUTION_REQUIRED:
                        // Location settings are not satisfied, but this can be fixed
                        // by showing the user a dialog.
                        try {
                            // Show the dialog by calling startResolutionForResult(),
                            // and check the result in onActivityResult().
                            ResolvableApiException resolvable = (ResolvableApiException) e;
                            resolvable.startResolutionForResult(activity,
                                    REQUEST_CHECK_SETTINGS);
                        } catch (IntentSender.SendIntentException sendEx) {
                            // Ignore the error.
                        }
                        break;
                    case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                        // Location settings are not satisfied. However, we have no way
                        // to fix the settings so we won't show the dialog.
                        break;
                }
            }
        });
    }

If the location setting is off, the dialog is shown but the problem is that when user touches outside the dialog, the dialog disappears. How can I prevent that? (sth like setCanceledOnTouchOutside(false) )?

note that location setting dialog is not my custom dialog. So I cannot set setCancelable(false) The dialog shows when these code is exccuted

// Show the dialog by calling startResolutionForResult(),
                            // and check the result in onActivityResult().
                            ResolvableApiException resolvable = (ResolvableApiException) e;
                            resolvable.startResolutionForResult(activity,
                                    REQUEST_CHECK_SETTINGS);
