React Native 实现热更新并自动签名打包功能

时间:2022-07-27
本文章向大家介绍React Native 实现热更新并自动签名打包功能,主要内容包括其使用实例、应用技巧、基本知识点总结和需要注意事项,具有一定的参考价值,需要的朋友可以参考一下。

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androidappsrcmainjavacomappMainApplication.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 Apistock_appandroidappsrcmainjavacomstock_appMainApplication.java:6: error: package com.microsoft.codepush.react does not exist
import com.microsoft.codepush.react.CodePush;
                  ^
C:Stock Apistock_appandroidappsrcmainjavacomstock_appMainApplication.java:23: error: cannot find symbol
    return CodePush.getJSBundleFile();
        ^
 symbol: variable CodePush
C:Stock Apistock_appandroidappsrcmainjavacomstock_appMainApplication.java:35: error: cannot find symbol
      new CodePush(null, getApplicationContext(), BuildConfig.DEBUG),
        ^
 symbol: class CodePush
3 errors
:app:compileDebugJavaWithJavac FAILED
 
FAILURE: Build failed with an exception.
 
* What went wrong:
Execution failed for task ':app:compileDebugJavaWithJavac'.
  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:

STACK TRACE AND/OR SCREENSHOTS :app:compileDebugJavaWithJavac – is not incremental (e.g. outputs have changed, no previous execution, etc.). C:Stock Apistock_appandroidappsrcmainjavacomstock_appMainApplication.java:6: error: package com.microsoft.codepush.react does not exist import com.microsoft.codepush.react.CodePush; ^ C:Stock Apistock_appandroidappsrcmainjavacomstock_appMainApplication.java:23: error: cannot find symbol return CodePush.getJSBundleFile(); ^ symbol: variable CodePush C:Stock Apistock_appandroidappsrcmainjavacomstock_appMainApplication.java:35: error: cannot find symbol new CodePush(null, getApplicationContext(), BuildConfig.DEBUG), ^ symbol: class CodePush 3 errors :app:compileDebugJavaWithJavac FAILED FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ‘:app:compileDebugJavaWithJavac’. 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 ? '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
