Tutorial 3

[cbeast]

I'm a total newbie to android and working my way through the Android
Programming Tutorials book. Doing OK, but I've hit a wall on the
Tutorial 3, where after adding the Radio Group I keep getting a
Stopped unexpectedly error. I've done a diff of the main.xml in the
online code and mine and nothing is popping out at me. Ideas? Below
is my main.xml and some output from adb logcat. Thank you!

Did you do a Force Clean (Eclipse) or ant clean (command-line), per
pages 24-25 (in Version 2.0 of the book)?

ClassCastExceptions are frequently triggered by resource IDs getting out
of sync, which the above steps should clear up. Certainly ant clean works.

No, I hadn't. I actually have the first edition of the book.
I don't see clean when calling ant help, is that something I need to
add?

Thank you so much for your help,
Chris

Hello

To clean a project and force a sync of resource

on Eclipse .... choose menu Project/Clean

Thanks, but I'm actually not using Eclipse. I'm working command line
like Mark is doing in the book.

Oh , sorry then :S

Sin más....
Me despido

That was added in Android 1.6 or so.

Just delete the bin/ and gen/ directories of your project -- that is all
ant clean really does.

Awesome! That did it - I could have sworn I tried that already, but
deleting the the two directories worked!
Thanks again for your help.

Do you think that is I built a new AVD that is 1.6 or later I would
avoid this problem on the rest of the tutorials?

No, it will crop up from time to time, particularly when you add resources.
