- Run your app
   - Open the LogCat View in Eclipse
   - Look for the Stack back trace in the LogCat view
   - Look for the line that says "Caused by" in the stack back trace
   - If this line is in your code put a breakpoint on that line and run 
   your program again:
      - When your program breaks in to the debugger look at your 
      code/variables in the debugger
      -  fix things
      - repeat :)
   - If it is NOT in your code the please post the LogCat stack dump here
