I'm getting a few reports in the Market of my users experiencing a
WindowManager$BadTokenException from an AlertBuilder.Builder.show()
call. (Full stack trace and relevant code below.) I've read what can
cause this to happen but no matter what I try, I can't cause the
exception to be thrown on any of my emulators or my Nexus One.
I've tried hitting the Back and Home buttons just as the dialog is
about to be displayed, changing the phone's orientation, and launching
multiple other apps in an attempt to get my app paused/resumed.
Anyone have any ideas on other actions I can take to try and cause the
exception?
Thanks,
Dave
