I am developing an application in Android Studio which allows opening Facebook and YouTube accounts, everything works fine, but when trying to play a video a black screen appears and only the audio is heard.

What can I do? I've tried everything but nothing works.

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {



    my_context = container.getContext();

    rootView = inflater.inflate(R.layout.fragment_web, container, false);

    preferences = PreferenceManager.getDefaultSharedPreferences(my_context);



    String type = getArguments().getString("type");

    String url = getArguments().getString("url");





    webView = (WebView) rootView.findViewById(R.id.webView);

    webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);

--------------- SWIPE CONTAINER ---------------

 swipeContainer = (SwipeRefreshLayout) rootView.findViewById(R.id.swipeContainer);

    // Setup refresh listener which triggers new data loading

    swipeContainer.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {

        @Override

        public void onRefresh() {

            webView.reload();

        }

    });

    // Configure the refreshing colors

    swipeContainer.setColorSchemeResources(android.R.color.holo_blue_bright,

            android.R.color.holo_green_light,

            android.R.color.holo_orange_light,

            android.R.color.holo_red_light);

------------------ WEBVIEW SETTINGS --------------------

WebSettings webSettings = webView.getSettings();



    // GET PREFERENCES

    if (preferences.getBoolean("pref_webview_cache", true)) {

        enableHTML5AppCache();

    }

    if (preferences.getBoolean("pref_webview_javascript", true)) {

        webSettings.setJavaScriptEnabled(true);

        webView.addJavascriptInterface(new WebAppInterface(my_context), "WebAppInterface"

-------------------- LOADER ------------------------

 pd = new ProgressDialog(my_context);

    pd.setMessage("Please wait Loading...");





    loader = preferences.getString("pref_webview_loader_list", "dialog");



    if (loader.equals("pull")) {

        swipeContainer.setRefreshing(true);

    } else if (loader.equals("dialog")) {
