4.Cannot find entry file index.android.js in any of the roots

react-native run-android 能启动成功 但是打包报错
在 ../../node_modules/react-native/react.gradles 文件中 添加

project.ext.react = [
    entryFile: "index.js"
]

然后就可以重新打包了

5. Installation failed with message Failed to establish session

用Android studio 2.3调度程序时提示“Installation failed with message Failed to establish session”错误，需要在在开发者选项里关闭MIUI优化！
