React Native 热更新-App端集成react-native-code-push

"react": "16.9.0",

"react-native": "0.61.5",

Android

在项目中安装 react-native-code-push插件，终端进入你的项目根目录然后运行

npm install --save react-native-code-push

插件适用于版本大于 React Native 0.60 version 的安装和配置步骤 (Android)

1. 在/android/settings.gradle中末尾添加如下代码:

   include ':app', ':react-native-code-push'
   project(':react-native-code-push').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-code-push/android/app')

2. 在 android/app/build.gradle文件里面添如下代码

   apply from: "../../node_modules/react-native/react.gradle"后面

   apply from: "../../node_modules/react-native-code-push/android/codepush.gradle"

3. 更新 MainApplication.java 按照如下代码:

   // 1. Import the plugin class.
   import com.microsoft.codepush.react.CodePush;
   
   public class MainApplication extends Application implements ReactApplication {
   
       private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {
           ...
   
           // 2. Override the getJSBundleFile method in order to let
           // the CodePush runtime determine where to get the JS
           // bundle location from on each app start
           @Override
           protected String getJSBundleFile() {
               return CodePush.getJSBundleFile();
           }
       };
   }

4. 添加 Deployment key 到 strings.xml:

　　让CodePush运行时知道应该查询哪个deployment 更新,在strings.xml文件并添加一个新的字符串CodePushDeploymentKey,其值要配置这个App的Deployment key(比如图中APP的Staging Deployment key)。用命令code-push deployment list appName -k 可以查询， 复制（如图）你想使用的Deployment key的值到Strings.xml中的CodePushDeploymentKey中。

strings.xml 应该像下面这样:

<resources>
     <string name="app_name">AppName</string>
     <string moduleConfig="true" name="CodePushDeploymentKey">DeploymentKey</string>
 </resources>

整合到本地code-push-server还要增加CodePushServerUrl，默认指向微软服务器，配置后指定本地服务器地址

<resources>
     <string name="app_name">AppName</string>
     <string moduleConfig="true" name="CodePushDeploymentKey">DeploymentKey</string>
　　  <string moduleConfig="true" name="CodePushServerUrl">http://127.0.0.1:3000</string>
 </resources>

Note: 如果需要动态地使用不同的部署，还可以在JS代码中使用 Code-Push options

为了有效地利用随CodePush应用程序一起创建的Staging 和Production deployments，可以使用以下配置 

For React Native >= v0.60

1.  在 android/app/build.gradle文件里面添如下代码

2. 找到 android { buildTypes {} } 这一部分，针对不同的编译发布环境增加 resValue

    ...
    buildTypes {
        debug {
            ...
            // Note: CodePush updates should not be tested in Debug mode as they are overriden by the RN packager. 
　　　　　　　// However, because CodePush checks for updates in all modes, we must supply a key.
            resValue "string", "CodePushDeploymentKey", ""
            ...
        }

        releaseStaging {
            ...
　　　　　　　//需要配置加密钥匙，可以复用release
　　　　　　　signingConfig signingConfigs.release
            resValue "string", "CodePushDeploymentKey", "<INSERT_STAGING_KEY>"
　　　　　　　//整合到本地code-push-server还要增加CodePushServerUrl，默认指向微软服务器，配置后指定本地服务器地址
　　　　　　　resValue "string", "CodePushServerUrl", "Server URL"
            // Note: It is a good idea to provide matchingFallbacks for the new buildType you create to prevent build issues
            // Add the following line if not already there
            matchingFallbacks = ['release']//定义子模块没有定义此buildTpye而用的buildType

            ...
        }

        release {
            ...
            resValue "string", "CodePushDeploymentKey", "<INSERT_PRODUCTION_KEY>"
　　　　　　　resValue "string", "CodePushServerUrl", "Server URL"

            ...
        }
    }
    ...
}

NOTE: 记得把以上的key从 strings.xml移除

NOTE:  releaseStaging 的命名约定参考 this line.
