Webview with Asynctask on Android

Webview with asynctask on Android

Don't use AsyncTask, as you are not in charge of loading the webview. If you want to show a progress dialog, here is how to do it.

private ProgressDialog dialog = new ProgressDialog(WebActivity.this);

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.webview);
    webView = (WebView) findViewById(R.id.webView1);

    Bundle extras = getIntent().getExtras();
    String url=extras.getString("adres");

    webView.setWebViewClient(new WebViewClient() {
        @Override
        public void onPageFinished(WebView view, String url) {                  
            if (dialog.isShowing()) {
                dialog.dismiss();
            }
        }
    });
    dialog.setMessage("Loading..Please wait.");
    dialog.setCanceledOnTouchOutside(false);
    dialog.show();
    webView.loadUrl(url);

    WebSettings webSettings = webView.getSettings();
    webSettings.setJavaScriptEnabled(true);
}

The idea is that you show the dialog, you start loading the url, and when the webclient sees that the page has finished loading, it dismisses the dialog.

how to update webview from AsyncTask

I think the only solution is to load your data with an http request in doInBackground then use
loadData in publishProgress.

Multiple AsyncTasks load the same WebView

Remove the private String result; line from the Async Task class.
