React Native 实现热更新并自动签名打包功能
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
...
apply from: "../../node_modules/react-native/react.gradle"
apply from: "../../node_modules/react-native-code-push/android/codepush.gradle"
...
dependencies {
implementation project(':react-native-code-push') //最好手动加上，否则可能会有坑
implementation fileTree(dir: "libs", include: ["*.jar"])
....
}
....
5.修改android/app/build.gradle文件
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
import com.microsoft.codepush.react.CodePush;
^

new CodePush(null, getApplicationContext(), BuildConfig.DEBUG),

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

> Compilation failed; see the compiler error output for details.
采坑：react-native-code-push需要手动添加依赖，否则会报错：

:app:compileDebugJavaWithJavac - is not incremental (e.g. outputs have changed, no previous execution, etc.).

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 ? '已完成' : '正在下载更新文件'}
describe={this.state.current === this.state.total ? '欢迎使用' : '请耐心等待'}
current={this.state.current} total={this.state.total}></UpdateDialog>}
</>
)
}
};
let codePushOptions = {
//设置检查更新的频率
//ON_APP_RESUME APP恢复到前台的时候
//ON_APP_START APP开启的时候
//MANUAL 手动检查
checkFrequency: CodePush.CheckFrequency.ON_APP_START
};
export default CodePush(codePushOptions)(App);
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
android.useAndroidX=true android.enableJetifier=true MYAPP_RELEASE_STORE_FILE=wms-app-key.jks //生成的签名密钥 MYAPP_RELEASE_KEY_ALIAS=ydh //别名 MYAPP_RELEASE_STORE_PASSWORD=签名时设置的密码 MYAPP_RELEASE_KEY_PASSWORD=签名时设置的密码
4.修改android/app/build.gradle
signingConfigs {
debug {
...
}
release {
if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {
storeFile file(MYAPP_RELEASE_STORE_FILE)
storePassword MYAPP_RELEASE_STORE_PASSWORD
keyAlias MYAPP_RELEASE_KEY_ALIAS
keyPassword MYAPP_RELEASE_KEY_PASSWORD
}
}
}
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
