I just deleted Eclipse and the Android SDK completely, and reinstalled them together from the Android SDK bundle. (I did this because a lot of bloat had built up over time and I couldn't get SDK Manager to recognize new versions of ADT.)
Eclipse used to pop up with a list of all available methods of a class if I typed the name of the class and then a dot, and would start filtering the list down as I continued to type. This feature is not working since I reinstalled. How can I turn it on?
I already installed API 17's sources and documentation in SDK Manager.
