[android-developers] Re: “BadTokenException: Unable to add window; is your activity running?” at showing dialog in PreferenceActivity
Maybe you get the error because the program hasn't exited it Perhaps
you need onPause and onResume or onExit or onRestart methods to handle
this correctly.

[android-developers] Re: “BadTokenException: Unable to add window; is your activity running?” at showing dialog in PreferenceActivity
Hi Vivek!
Thank You for posting!
I tried what You suggesed, but the problem is still on. Setting
postDelayed() executing to 5 sec, and the app is still crashing. So I
think the problem isn't based on timeing, the activity started after
300-400 millisecs, but system doesn't find it, or something like this
could happening...
If You'll have any other idea, I'll try it; that would be big help to
me!
Thanks,
lama

[android-developers] Re: “BadTokenException: Unable to add window; is your activity running?” at showing dialog in PreferenceActivity
Hi lama,
I once had this android.view.WindowManager$BadTokenException when i
was trying to load the dialog too early.
It was resolved by delaying the showdialog call.
U can try it by using Handler().postDelayed()
Thanks,
vivek
