Невозможно загрузить React Native URL в Android Webview

Question

Я пытаюсь загрузить URL-адрес собственного приложения в свой Android Webview. Это вообще не загрузка показывает только белый экран. Есть ли что-нибудь добавить для загрузки сайтов React Native для загрузки в веб-представлении Android.

Вот код:

public class MainActivity extends AppCompatActivity {

    private static ProgressDialog progressDialog;
    private static AlertDialog alertDialog;
    private static final String TAG = "MainActivity";
    private boolean doubleBackToExitPressedOnce = false;
    private static int OPEN_SETTINGS_ACTIVITY = 5;
    String webURL = "https://my.react.app"; // original react site URL goes here
    private WebView webView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //Remove title bar
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        //Remove notification bar
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.activity_main);

        webView = findViewById(R.id.webView);

        /*if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            // chromium, enable hardware acceleration
            webView.setLayerType(View.LAYER_TYPE_HARDWARE, null);
        } else {
            // older android version, disable hardware acceleration
            webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
        }*/

        if (ConnectivityReceiver.isNetworkAvailable(this)) {
            loadWebView();
        } else {
            showNoInternetDialog(this);
        }
    }

    @SuppressLint("SetJavaScriptEnabled")
    private void loadWebView() {
        WebSettings webViewSettings = webView.getSettings();
        webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);

        webViewSettings.setJavaScriptEnabled(true);
        webViewSettings.setJavaScriptCanOpenWindowsAutomatically(true);
        webViewSettings.setSupportMultipleWindows(true);

        webViewSettings.setSupportZoom(true);
        webViewSettings.setBuiltInZoomControls(true);
        webViewSettings.setDisplayZoomControls(false);

        // to save it in offline
        webViewSettings.setAppCachePath(this.getApplicationContext().getCacheDir().getAbsolutePath());
        webViewSettings.setAllowFileAccess(true);
        webViewSettings.setAppCacheEnabled(true);
        webViewSettings.setCacheMode(WebSettings.LOAD_DEFAULT); // load online by default

        webViewSettings.setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);

        webView.loadUrl(webURL);

        webView.setWebViewClient(new WebViewClient() {

            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon) {
                progressDialog = showProgressDialog(view.getContext(), "Loading..", true);
                super.onPageStarted(view, url, favicon);
            }

            @Override
            public void onPageFinished(WebView view, String url) {
                if (progressDialog.isShowing()) {
                    hideProgressDialog(progressDialog);
                }
            }

            @Override

                super.onReceivedError(view, request, error);
                hideProgressDialog(progressDialog);
            }
        });
    }

    public static ProgressDialog showProgressDialog(Context context, String title, boolean isCancelable) {
        try {
            // create a progress bar while the video file is loading
            progressDialog = new ProgressDialog(context);
            // set a title for the progress bar
            progressDialog.setTitle(title);
            // set a message for the progress bar
            progressDialog.setMessage("Please wait...");
            //set the progress bar not isCancelable on users' touch
            progressDialog.setCancelable(isCancelable);
            // show the progress bar
            progressDialog.show();

            return progressDialog;
        } catch (Exception e) {
            Log.e(TAG, e.getMessage(), e);

    @Override

        closeApp();
    }

    private void closeApp() {
        if (doubleBackToExitPressedOnce) {
            finish();
        }

        this.doubleBackToExitPressedOnce = true;
        Toast.makeText(this, "Please click BACK again to exit", Toast.LENGTH_SHORT).show();

        new Handler().postDelayed(new Runnable() {

            @Override
            public void run() {
                doubleBackToExitPressedOnce = false;
            }
        }, 2000);
    }

    public static void showNoInternetDialog(final Activity context) {
        try {
            alertDialog = new AlertDialog.Builder(context)
                    .setMessage("No internet available. Click OK to go settings, enable WiFi")
                    .setPositiveButton("OK", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            Intent callWiFiSettingIntent = new Intent(Settings.ACTION_WIFI_SETTINGS);
                            context.startActivityForResult(callWiFiSettingIntent, OPEN_SETTINGS_ACTIVITY);
