I am trying to clear a webview from the view in my application.

I clear this by using: MyWebView.loadUrl("about:blank");

This works sometimes, but other times when I load the emulator this gives a force close error:

Is there any other way to clear the webview from the view.

Thanks


Raj,

Perhaps you simply want to use the clearView() method?


how to hide the "Web Page not available" text when web View fails to load the page. MyWebView.clearView() is not working.
