Development

(科学上网依然很慢

For MacOS

1. 安装node, watchman.

   brew install node

   brew install watchman

2. 安装JDK

   建议直接官网下载JDK8或者更新版本.

3. 安装Android开发环境

   下载Android Studio后，勾选相关依赖即可.

4. 安装react-native-cli

   npm i -i react-native-cli

5. 运行已存在的项目

react-native run-android

Problem

1. 官网文档太老了

   环境变量（注意第4行，和官网的不一样）.

   同时cmdline-tools需要在Android Studio自行下载.

   export ANDROID_HOME=$HOME/Library/Android/sdk
   export PATH=$PATH:$ANDROID_HOME/emulator
   export PATH=$PATH:$ANDROID_HOME/tools
   export PATH=$PATH:$ANDROID_HOME/cmdline-tools/latest/bin
   export PATH=$PATH:$ANDROID_HOME/platform-tools
   

2. gradle下载失败

   手动下载，把压缩包放在/android/gradle/wrapper内，然后修改该目录下的gradle-wrapper.properties将其下载地址目标改为当前目录下已经下载的文件路径.

   然后需要手动导出环境变量(把压缩包解压到/usr/local)

   export GRADLE_USER_HOME=/usr/local/gradle-6.0.1

   export PATH=$PATH:$GRADLE_USER_HOME/bin

3. gradle自动安装失败 在android/build.gradle中配置镜像源，如下

   buildscript {
       ext {
           buildToolsVersion = "28.0.3"
           minSdkVersion = 16
           compileSdkVersion = 28
           targetSdkVersion = 28
       }
       repositories {
   +        maven { url 'https://maven.aliyun.com/repository/google'}
   +        maven { url 'https://maven.aliyun.com/repository/jcenter'}
   +        maven { url 'https://maven.aliyun.com/repository/public'}
       }
   - 			 // remove other repo
       dependencies {
           classpath("com.android.tools.build:gradle:3.5.2")
   
           // NOTE: Do not place your application dependencies here; they belong
           // in the individual module build.gradle files
       }
   }

4. 建议使用flutter

API

Yapi
