The Android Connected Android Project has been deprecated. When installing Eclipse 4.2 and the current GPE, I do not see this option. Endpoints have replaced this.
The easiest way to get started with IMO is to create an Android project, and then use the AppEngine Backend Generator Wizard (i.e., select the Android project in the package explorer and then find this wizard in the Google submenu).
This will create an App Engine project with endpoints and configure it to automatically copy your endpoint libraries to your Android project when you select "generate endpoint libraries for clouds."
