Answer 1 :

You're trying to show a Dialog after you've exited an Activity.

Answer 2

This error can be a little misleading in some circumstances (although the answer is still completely accurate) - i.e. in my case an unhandled Exception was thrown in an AsyncTask, which caused the Activity to shutdown, then an open progressdialog caused this Exception.. so the 'real' exception was a little earlier in the log

Answer 3

Call dismiss() on the Dialog instance you created before exiting your Activity, e.g. in onPause() or onDestroy()

The solution is to call dismiss() on the Dialog you created in viewP.java:183 before exiting the Activity, e.g. in onPause(). All Windows&Dialogs should be closed before leaving an Activity.

If you are using AsyncTask, probably that log message can be deceptive. If you look up in your log, you might find another error, probably one in your doInBackground() method of your AsyncTask, that is making your current Activity to blow up, and thus once the AsyncTask comes back.. well, you know the rest. Some other users already explained that here :-)
