Create Options from a class that extends View Parent Class

Postby viju85 » Wed Feb 03, 2010 5:27 am

I am developing an application and i am unable to sovle this issue for about a week.
May be this sounds trivial, but i guess it may be very useful to many others like me.

I have a class A that extends Activity which calls another class B that extends View using setContentView().

Within the class B i am not able to make use of AlertDialog or any Dialog for that matter.
I get the following error on logcat:

Exception in alertNewGame() Method: android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application

Please help me on how to go about it.

I think typically that means you are trying to open a window from outside of the main UI thread...

In other words, AlertDialogs/Dialogs can only be instantiated from within the Activity
