How can I skip runing into Android class code when debugging My own project?

New to android, when I debugging in Eclipse I use to press F6 to step into my code, but by doing this, it always lead me into source code of Android which I don't have, than, you can see the page with a button let you to browse the location of the source code, how can I skip this, an开发者_如何学Cd let the debugger always stay within my own project?

Thanks.

I knew it should be possible!
