There is just an Exchange account provider pre-installed in the emulator when building Android 2.3.3 from sources, although I expected better Google support (ie. Google account provider).
Where do I get the source code for “Google Services Framework”? Is it open-source at all?
First, check that you’ve installed “Google APIs by Google Inc.” for that version of Android in the SDK Manager.
Then create your avd using Google API for that version rather than just the vanilla copy.
