I'm trying to add a simple swipe refresh to a webview layout. I have searched all over and tried different methods from things that I have found on GitHub and Android Developers pages but nothing seems to work. When I load the web page with the code without the OnRefresh method in the code it loads just fine. But as soon as I enable the method the page just closes the application. Any advice would be great as I'm new to android (1 yr exp) and trying to learn. Thanks

Here is a sample of the code I'm working with. Hope I don't post to much info every time I ask a question here I get told I'm posting too much!!

private AboutViewModel AboutViewModel;
SwipeRefreshLayout swipe;

public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View root;
    AboutViewModel = new ViewModelProvider(this).get(AboutViewModel.class);
        root = inflater.inflate(R.layout.fragment_about, container, false);

        WebView webView = root.findViewById(R.id.web_view_about);
        webView.loadUrl("https://example.com");
        webView.setWebViewClient(new WebViewController());

    swipe = (SwipeRefreshLayout) container.findViewById(R.id.swipe);
    swipe.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
        @Override
        public void onRefresh() {
            webView.reload();
        }
    });
    return root;
}

This is the layout xml

<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@ id/swipe"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <WebView
        android:id="@ id/web_view_about"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</androidx.swiperefreshlayout.widget.SwipeRefreshLayout>

Replace container with root like below:

swipe = root.findViewById(R.id.swipe);
        swipe.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                webView.reload();
                swipe.setRefreshing(false); // Call this at the end of loading
            }
        });
