How can I add WebView into a Widget?

I'm trying to make a recording Widget where the user interface would be loaded from HTML page in WebView. Is this possible? I've been trying to load url into Widget but I get all sorts of errors and my program crashes. I'm new to Android development and don't really know how this stuff works yet.

This is my Widget provider class:

public class RecordAppWidgetProvider extends AppWidgetProvider {
WebView webview;
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
    webview.getSettings().setJavaScriptEnabled(true);
    webview.loadUrl("http://www.google.com");
    webview.setWebViewClient(new WebViewClient());

}
}

I think I'll have to load the WebView in some way, normally I do it with this:

webview = (WebView) findViewById(R.id.webview);

But it doesn't work here, I think findViewById is from Activity?
