Android Studio 2.3 instant run与miui冲突问题的解决

Android Studio最近发布的2.3版本，由于这个版本改进后的Instant Run功能和很多国内ROM存在兼容问题，所以导致不得不做一些妥协策略，具体在小米Rom上，就是把小米rom的调试定制优化功能关闭掉：

In case you are running a device with MIUI, Go to Developer Settings > Turn on MIUI optimization and turn it off.

You will then need to restart your device and recompile the code.

Instant Run should then work again
