Sun's R&D resources in developing Java. Did you read this part of the article? So basically they piggybacked the Android development environment on the work Sun/Oracle did. To me, it's the technological equivalent of Ford setting up an assembly line for cars, then having someone come along and add an extra station at the end of the line which swaps the Ford logos for KIA logos and then delivering the cars to KIA dealerships.
