Hi i am developing a TabBar application which consists of four tabs. Whenever the application is opened the first tab gets selected.In the first tab i am loading a WebView which consists of HTML 5 content(some labels and Textboxes). After entering some data in TextBoxes and able to navigate to the another WebView, in this WebView i am having a spinner i.e.,an HTML spinner. But whenever i click on that spinner i am getting the following Exception:
**02-15 15:16:56.081: E/AndroidRuntime(6133): android.view.WindowManager$BadTokenException: Unable to add window -- token android.app.LocalActivityManager$LocalActivityRecord@449e45c8 is not valid; is your activity running?

Are you using an activity group?
if you are using try to inflate layout instead of setcontentview(yourlayout)
