1 Error plugin 
在某些情况下，比如你的android-studio没有关闭，然后你强制关机，当再次打开android-studio时，会出现这个问题

Plugin "Google Analytics Uploader" was not loaded: required plugin "Android Support" is disabled  Plugin "SDK Updater" was not loaded: required plugin "Android Support" is disabled. Plugin "Android NDK Support" was not loaded: required plugin "Android Support" is disabled. Plugin "Google App Indexing" was not loaded: required plugin "Android Support" is disabled. Plugin "Google Cloud Tools For Android Studio" was not loaded: required plugin "Android Support" is disabled. Plugin "Google Cloud Testing" was not loaded: required plugin "Android Support" is disabled Plugin "Google Services" was not loaded: required plugin "Android Support" is disabled.

解决方法： 
点击File下面的Settings（快捷键 alt+ctrl+s） 
找到plugin 发现有一些插件为红色 
点击这些红色插件的后面的勾勾 
再重启 就OK了

2 Write access is allowed from event dispatch thread only

解决方式： 
File->project structure->Android sdk -> embedded 
给当前的android studio的jdk换个版本，使用android studio 自带的jre。JDK版本 和 sdk版本冲突。 
仍点击不了运行按钮，则在右上角的锤子图标和运行图标之间的一个下拉三角形，选择app，则运行图标可点击了

3 Unsupported Modules Detected: Compilation is not supported for following modules 
File->invalidate caches/Reset->invalidate and reset 
重新运行就OK

4 XML文件打不开 
也是 
File->invalidate caches/Reset->invalidate and reset 
清理一下caches

5 点不了install 
看install什么，如果是要install API 则可以去SDK Manager中install相应的API版本
