Android Studio 2.2 Preview 6 发布了。
该版本并没有大的改进提升，只是对一些已知bugs进行修复，增强优化旧有功能，提升运行性能。如下：
Performance: We addressed a number of crashes that were introduced in Preview 5 and prior previews.
Other: Several other fixes across the product - in instant run, deployment, lint, C++/CMake/NDK support, etc.
遗憾的是，该版本没有解决之前出现的issue 21555: C/C++ 标识问题。
