Android Development and the Case of the Missing Google Maps Reference SDK
The Android Developer site has moved a bunch of links around to remove a lot of the Google branding from the community. Technically speaking Google drove the project and owns a lot of the development but it is an open-source community and probably should avoid proprietary and company specific codebases within its structure.
That at least what I assume they were thinking when they yanked the com.android.maps reference documentation from the site. For instance if you were looking for the MapController reference you would run a Google search for it and the first link is this:
http://code.google.com/android/reference/com/google/android/maps/MapController.html
Which returns a bug fat 404. The proper link is at:
http://code.google.com/android/add-ons/google-apis/reference/index.html
Android/Google get it together! At least put a redirect page up on old links!
Hopefully that saves you some time with the SDK.
