Question

I’d like to start a WebView from my AsyncTask but it doesn’t seem to run. This is what my onPostExecute method looks like:

  public class Viewer extends AsyncTask<URI, Integer, URI> {

      private Activity objContext = null;

      public Viewer(Activity objContext) {
        this.objContext = objContext;
      }

      protected void onPostExecute(URI uriWebpage) {
          WebView wbvBrowser = new WebView(this.objContext);
          wbvBrowser.getSettings().setBuiltInZoomControls(true);
          wbvBrowser.getSettings().setJavaScriptEnabled(true);
          wbvBrowser.loadUrl(uriWebpage.toString());
      }

  }

My task is used by two activities in my application and therefore my global objContext variable is of type Activity. If I change the type of my objContext variable to the name of the calling class, it works fine but then I can’t instantiate my task from the other calling class. I instantiate my task like this.

Viewer mytask = new Viewer(this);

How can I solve this?

I have solved the issue. It has nothing to do with the use of Activity or Context. Both work just fine. Some URLs don’t seem to load the WebView. I changed the URL of the WebView to point to a site like Google and it worked just fine. Seems like if the URL is incorrect, the WebView doesn’t throw an exception but doesn’t open up either.
