For some reason I can't step through the code in the debugger. I am not trying to step through Android source code, just code that resides in my project. My build paths are setup to include it, but whenever I try stepping over anything it gives me a "Source not found" message. This is incredibly frustrating, and a prompt answer would be very well appreciated.
Android SDK doesn't include source code. How do you setup your build path? Check these articles, if you want to browse android framework source code under eclipse and set break point. But I did not try these methodology recently.

I dont think the poster wants to step through the java source code. What he wants to do is avoid stepping into the core libraries. Fortunately eclipse does let you do this using step filters (though why this isnt enabled by default ill never know, i would have thought people wanting to debug the core libraries would be the edge case ...). To do this, you can go to Window -> Preferences -> Java -> Debug -> Step Filtering, turn it on and check the packages you want to automatically step over (i check them all).
