We're not sure what anniversary the 17th is but, if we had to guess, we'd say its the x86 anniversary. Google has just released Revision 17 of the Android SDK and ADT and its packing an array of improvements, most notably to the Lint build system and the emulator. While the new build rules, which check performance and guard against errors, are certainly welcome, it's the emulator that's got the headline grabbing changes. First off is the ability to run x86 system images in a virtualized environment (on Windows and OS X), and at near native speeds no less. There is also added support for webcams and sensors, as well as the experimental ability to control the emulator through a tethered android device.
