the Java sources for the Android framework are available at source.android.com. Can I download and feed them to Eclipse so that I can step into framework methods while debugging? Better yet, does anyone know of an Eclipse plug-in that would get them from Android Git automatically as needed?
EDIT: during debugging, I can step through the framework code; I can see local variables by their declared names, and line numbers as well. It seems like the debug info is already there - only the source file is missing. While I can open it in parallel and watch the execution unfold, the question of version matching remains. Of many versions of the class file in Git, how do I pick one that matches whatever is running on the device (or emulator)? This is more of a Git navigation question - how do I pick up the very version of the file that went into Android release, say, 2.2?
EDIT much later: now sources come prepackaged with Android SDK. This question is somewhat obsolete.
This article nicely explains how to accomplish this: http://android.opensourceror.org/2010/01/18/android-source/
