Take a look at the logcat output... What do you see? It should give you the reason for the crash as well as a stack trace that often points the exact file and line number that is the cause.

Hi there,
I wrote this short android program, however I am geting a problem. When the context menu appears and I click for instance
on one of its items such as "Edit" or "Delete". a system pop up alert info arise saying that the process stoped unexpectedly.
