    webSettings.setJavaScriptEnabled(true);

    new asynctask().execute();

}

Solution 1:

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.
