RN与android原生开发混合后的环境报错问题

需要先安装nodejs

$ yarn --version

1.12.1

更新当前版本

yarn upgrade --latest

安装 | Yarn

================

到对应目录下用git bash here执行：

yarn

================

yarn start

npm install

================

rn混合后编译卡的问题，到D:\exchangespace目录下，cmd执行下面命令打包到D:\exchangespace\android\app\src\main\assets里面直接使用，只有rn的代码更新了才需要重新打包

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android\app\src\main\assets\index.android.bundle --assets-dest android\app\src\main\res\

=================

有时候构建Android studio项目，会莫名出现

error: resource android:style/TextAppearance.Material.Widget.Button.Colored not found.

Error:resource android:style/TextAppearance.Material.Widget.Button.Borderless.Colored not found的问题，并且还会引起一系列其他的问题。

修改方法：

将compileSdkVersion修改成25，并将对应的buildToolsVersion修改成25.0.2

=================

Configuration 'compile' is obsolete and has been replaced with 'implementation' and 'api'.

It will be removed at the end of 2018. For more information see: http://d.android.com/r/tools/update-dependency-configurations.html

Configuration 'testCompile' is obsolete and has been replaced with 'testImplementation' and 'testApi'.

Configuration 'testApi' is obsolete and has been replaced with 'testImplementation'.

dependencies {

compile fileTree(include: ['*.jar'], dir: 'libs')

compile 'com.facebook.react:react-native:+'

}

dependencies {

implementation fileTree(include: ['*.jar'], dir: 'libs')

implementation 'com.facebook.react:react-native:+'

}

------------

compile --> implementation

testCompile --> testImplementation

testApi --> testImplementation

provided --> compileOnly

======================

不同严重程度可以按以下三种处理：

1.切换到project视图，删除.grade .idea 文件夹，clean project，

2.关闭android，重新打开编译

3.彻底清除缓存 File -> Invalidate Caches / Restart... （会清理掉本地修改的Gradle配置）

======================

Quit emulator

Quit Android Studio

Reopen Android Studio

Build > Clean Project

Run/debug your app onto your device/emulator again

======================
