Android Studio升级到2.3版本之后，小米手机MIUI8不能运行Android Studio程序，报如下错误:

it is possible that this issue is resovled by uninstalling an existing version of the apk if it is present
Installation failed with message Failed to establish session. It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then reinstalling. WARNING: Uninstalling will remove the application data!
Do you want to uninstall the existing application?

解决办法:

设置→搜索Instant Run→Enable Instant Run to hot swap code/resource changes on deploy(default enabled)选项的选择框取消（就是将其不选中）→Apply
