Hi,

The code itself is fine except that you don't print the exception.

If you would log the exception you can see (in the LogCat) that the run-time is throwing some kind of a ParseException. This is since users (usually) don't type 'L' at the end of their numeric input, even when it's long.

Hope this helps
