SDK Tools, Revision 16 (December 2011)
Added Lint tools to detect common errors in Android projects.

Added support for using a webcam to emulate a camera on Mac OS X.
Snapshots now work for Android 4.0 system images.
Fixed several small issues for the build file
Enabling GPU also works now in emulator, but OpenGL ES2.0 itself is yet not emulated.
