项目背景：手动link的安卓App
1.下载 react-native-code-push
npm install --save react-native-code-push
2.在android/settings.gradle文件下新增：
include ':app', ':react-native-code-push'
project(':react-native-code-push').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-code-push/android/app')
3.在android\app\src\main\java\com\app\MainApplication.java 文件中修改

...// 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(); } //手动link需要修改的地方,自动link应该不需要改 @Override protected List<ReactPackage> getPackages() { @SuppressWarnings("UnnecessaryLocalVariable") List<ReactPackage> packages = new PackageList(this).getPackages(); // Packages that cannot be autolinked yet can be added manually here, for // example: // packages.add(new MyReactNativePackage()); packages.add(new CodePush(getResources().getString(R.string.CodePushDeploymentKey), getApplicationContext(), BuildConfig.DEBUG, getResources().getString(R.string.reactNativeCodePush_androidServerURL))); return packages; } };} //CodePushDeploymentKey对应string.xml里面的 Deployment key的name//reactNativeCodePush_androidServerURL对应string.xml里面热更新服务地址的name |
4.string.xml的修改：首先要将你的app添加到推送中心，并获取你需要的环境分支的key
4.1.登录热更新服务器
4.2.推送中心创建项目：（针对第一次部署）
code-push app add 项目名称 android react-native
4.3 添加环境分支dev：code-push deployment add 项目名称 dev （针对第一次部署）
将项目打包至对应的环境分支，需要将环境分支对应的key和热更新地址配置到项目文件中：(strings.xml)
4.4 准备工作已经做好了，现在我们来修改string.xml文件吧

5.修改android/app/build.gradle文件

采坑：react-native-code-push需要手动添加依赖，否则会报错：
STACK TRACE AND/OR SCREENSHOTS
:app:compileDebugJavaWithJavac - is not incremental (e.g. outputs have changed, no previous execution, etc.).
C:\Stock Api\stock_app\android\app\src\main\java\com\stock_app\MainApplication.java:6: error: package com.microsoft.codepush.react does not exist

3 errors
:app:compileDebugJavaWithJavac FAILED
FAILURE: Build failed with an exception.
* What went wrong:

> Compilation failed; see the compiler error output for details.
6.采坑：手动link react-native-code-push的app，需要禁止autolink，否则会报错：
java.lang.IllegalStateException: Native module CodePush tried to override CodePushNativeModule. Check the getPackages() method in MainApplication.java, it might be that module is being created twice. If this was your intention, set canOverrideExistingModule=true
所以需要加上一个配置文件，禁止自动link
在项目根目录创建react-native.config.js文件

module.exports = { dependencies: { 'react-native-code-push': { platforms: { android: null, // disable Android platform, other platforms will still autolink }, }, },}; |
7.热更新配置完成，现在我们需要在项目启动的时候检测热更新，并提示
在项目入口文件App.js中：

import React,{ Component } from 'react';import Root from './src/inner';import configureStore from './src/inner/store';import UpdateDialog from './src/common/components/updateDialog'import CodePush from "react-native-code-push"; const { persistor, store } = configureStore(); class App extends Component { state = { visitDialog: false, current: 0, total: 100 } componentDidMount() { CodePush.sync({ //安装模式 //ON_NEXT_RESUME 下次恢复到前台时 //ON_NEXT_RESTART 下一次重启时 //IMMEDIATE 马上更新 installMode: CodePush.InstallMode.IMMEDIATE, //对话框 updateDialog: { //是否显示更新描述 appendReleaseDescription: true, //更新描述的前缀。 默认为"Description" descriptionPrefix: "更新内容：", //强制更新按钮文字，默认为continue mandatoryContinueButtonLabel: "立即更新", //强制更新时的信息. 默认为"An update is available that must be installed." mandatoryUpdateMessage: "必须更新后才能使用", //非强制更新时，按钮文字,默认为"ignore" optionalIgnoreButtonLabel: '稍后', //非强制更新时，确认按钮文字. 默认为"Install" optionalInstallButtonLabel: '后台更新', //非强制更新时，检查到更新的消息文本 optionalUpdateMessage: '有新版本了，是否更新？', //Alert窗口的标题 title: '更新提示' }, }, (status) => { console.log(status, 'status') if (status == 7) { this.setState({ visitDialog: true }) } }, (progress) => { let receivedBytes = progress.receivedBytes / 1024 / 1024; let totalBytes = progress.totalBytes / 1024 / 1024; this.setState({ current: receivedBytes, total: totalBytes }) if (receivedBytes === totalBytes) { setTimeout(() => { this.setState({ visitDialog: false }) }, 1000) } console.log(progress, 'progress') } ); } render() { console.log(this.state.visitDialog, 'visitDialog'); return ( <> <Root store={store} persistor={persistor} /> {this.state.visitDialog && <UpdateDialog title={this.state.current === this.state.total ?

UpdateDialog ：是我自己封装的热更新下载进度条的组件，下载提示，可根据自己的心情随便写，这里我就不贴自己的代码了！（写的不好，不好意思）
现在我们热更新配置好了，打包正式的apk吧！
1. 生成签名文件：在项目根目录下运行命令：
keytool -genkey -v -keystore 我的签名-key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias 我的签名
2.将生成的签名文件拷贝至目录：android/app目录下
3.配置gradle.properties

4.修改android/app/build.gradle

5..打包(android目录下)： .\gradlew.bat assembleRelease
app打包成功，将apk拷贝到手机安装即可
6..推送代码：(需要更新时，推送代码到你想要更新的环境分支)
推送到dev环境：code-push release-react 项目名称 android -d dev
推送到production环境:-m true 代表强制更新，不加代表不强制更新
code-push release-react 项目名称 android -d Production -m true
然后重启app，就可以看到更新提示啦
