The Android SDK was updated to revision 17 earlier today, bringing with it the usual sort of bug fixes (for Lint) and adding performance improvements specifically, to the emulator for x86 devices. Thanks to Intel’s contributions to AOSP, the emulator now runs at almost native speed and is no longer sluggish. Unfortunately, the new x86 improvements are only working for Android 2.3 at the moment, but this is still a step in the right direction. Also added was support for multitouch on tethered devices, which should help in creating apps for all you developers out there. Have fun.
