Definition Found
Thanks for the reply, Edgar, but that one exception was not in that blog.
I did find another good list of Exception Definitions online at:
Exception | Android Developers
under "Known Indirect Subclasses".
The ClassCastException is thrown during runtime when a program "attempts to cast an object to a type with which it is not compatible". So I'll just have to examine my code to figure out which variable or assignment is the cause of the Exception.
