When I debug the sample project "helloworld" firstly, I got the message of "uncaught exception..." on simulator screen and the message of "source code is not available" on my IDE debugger.

I'm a fresh. Help!

i would guess it is the old 'resources not found' problem. they are in a different directory and if you copy the samples somewhere else you have to take them with you.

Yes, it was the problem about resource project.
There is a independence resource project for all the sample projects.

Thanks a lot.
