[android-developers] Re: methods not working (force closing), is there something wrong?
Okay, I see. So what would be a solution to an error like that? I'm a PHP programmer in which I can write some sloppy code... I'm sort of lost on that.

It is a lot easier to use ddms and find the exact exception and get
the stack trace to figure out what's wrong.
