React Native 常见问题总结（android端）

1.运行项目，出现中文乱码

我使用的是webStorm开发，修改File -→File Encoding编码格式为utf-8,File→Setting→Editor→File Encoding，全部修改为 utf-8。Reload下试试。

2.真机上运行，修改了js代码，Reload时候，需要多次刷新，才有效果

Reload时候，运行着服务的命令窗口，需要在最前端，难道是我笔记本配置太菜，才遇到这个问题。

3.React Native Android: screenPhysicalPixels.width is undefined

You need to update the string in android/app/build.gradle to

dependencies {
compile “com.facebook.react:react-native:0.20.+”}

Then just run

npm start

react-native run-android

4.命令行：React-Native Command run-android unrecognized.Did you mean to run this inside a react-native project?

You can try to do npm install before react-native run-android

5.A problem occurred congfiguring project ‘app’

这个是 package.json中 react-native 版本号与android/app下build.gradle中react-native 不一致。一般改为 compile “com.facebook.react:react-native:+” 就可以了
