React Native如何實現熱更新并自動簽名打包功能

發布時間:2020-08-03 09:47:55 來源:億速云 閱讀:565 作者:小豬 欄目:移動開發

這篇文章主要講解了React Native如何實現熱更新并自動簽名打包功能,內容清晰明了,對此有興趣的小伙伴可以學習一下,相信大家閱讀完之后會有幫助。

項目背景:手動link的安卓App

1.下載 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();
    }
  //手動link需要修改的地方,自動link應該不需要改
      @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對應string.xml里面的 Deployment key的name
//reactNativeCodePush_androidServerURL對應string.xml里面熱更新服務地址的name

4.string.xml的修改:首先要將你的app添加到推送中心,并獲取你需要的環境分支的key

 4.1.登錄熱更新服務器  

 4.2.推送中心創建項目:(針對第一次部署)

         code-push app add 項目名稱 android react-native

4.3 添加環境分支dev:code-push deployment add 項目名稱 dev (針對第一次部署)

將項目打包至對應的環境分支,需要將環境分支對應的key和熱更新地址配置到項目文件中:(strings.xml)

4.4 準備工作已經做好了,現在我們來修改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') //最好手動加上,否則可能會有坑
  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;
                  ^
C:\Stock Api\stock_app\android\app\src\main\java\com\stock_app\MainApplication.java:23: error: cannot find symbol
    return CodePush.getJSBundleFile();
        ^
 symbol: variable CodePush
C:\Stock Api\stock_app\android\app\src\main\java\com\stock_app\MainApplication.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需要手動添加依賴,否則會報錯:

  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;
                                   ^
C:\Stock Api\stock_app\android\app\src\main\java\com\stock_app\MainApplication.java:23: error: cannot find symbol
        return CodePush.getJSBundleFile();
               ^
  symbol: variable CodePush
C:\Stock Api\stock_app\android\app\src\main\java\com\stock_app\MainApplication.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:手動link react-native-code-push的app,需要禁止autolink,否則會報錯:

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

所以需要加上一個配置文件,禁止自動link

在項目根目錄創建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.熱更新配置完成,現在我們需要在項目啟動的時候檢測熱更新,并提示

在項目入口文件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({
   //安裝模式
   //ON_NEXT_RESUME 下次恢復到前臺時
   //ON_NEXT_RESTART 下一次重啟時
   //IMMEDIATE 馬上更新
   installMode: CodePush.InstallMode.IMMEDIATE,
   //對話框
   updateDialog: {
    //是否顯示更新描述
    appendReleaseDescription: true,
    //更新描述的前綴。 默認為"Description"
    descriptionPrefix: "更新內容:",
    //強制更新按鈕文字,默認為continue
    mandatoryContinueButtonLabel: "立即更新",
    //強制更新時的信息. 默認為"An update is available that must be installed."
    mandatoryUpdateMessage: "必須更新后才能使用",
    //非強制更新時,按鈕文字,默認為"ignore"
    optionalIgnoreButtonLabel: '稍后',
    //非強制更新時,確認按鈕文字. 默認為"Install"
    optionalInstallButtonLabel: '后臺更新',
    //非強制更新時,檢查到更新的消息文本
    optionalUpdateMessage: '有新版本了,是否更新?',
    //Alert窗口的標題
    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 &#63; '已完成' : '正在下載更新文件'}
     describe={this.state.current === this.state.total &#63; '歡迎使用' : '請耐心等待'}
     current={this.state.current} total={this.state.total}></UpdateDialog>}
   </>
  )
 }
};
 
let codePushOptions = {
 //設置檢查更新的頻率
 //ON_APP_RESUME APP恢復到前臺的時候
 //ON_APP_START APP開啟的時候
 //MANUAL 手動檢查
 checkFrequency: CodePush.CheckFrequency.ON_APP_START
};
 
export default CodePush(codePushOptions)(App);

UpdateDialog :是我自己封裝的熱更新下載進度條的組件,下載提示,可根據自己的心情隨便寫,這里我就不貼自己的代碼了!(寫的不好,不好意思)

現在我們熱更新配置好了,打包正式的apk吧!

1. 生成簽名文件:在項目根目錄下運行命令:

keytool -genkey -v -keystore 我的簽名-key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias 我的簽名

2.將生成的簽名文件拷貝至目錄:android/app目錄下

3.配置gradle.properties

android.useAndroidX=true
android.enableJetifier=true
MYAPP_RELEASE_STORE_FILE=wms-app-key.jks //生成的簽名密鑰
MYAPP_RELEASE_KEY_ALIAS=ydh //別名
MYAPP_RELEASE_STORE_PASSWORD=簽名時設置的密碼
MYAPP_RELEASE_KEY_PASSWORD=簽名時設置的密碼

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目錄下): .\gradlew.bat assembleRelease 

app打包成功,將apk拷貝到手機安裝即可

6..推送代碼:(需要更新時,推送代碼到你想要更新的環境分支)

推送到dev環境:code-push release-react 項目名稱 android -d dev

推送到production環境:-m true 代表強制更新,不加代表不強制更新

code-push release-react 項目名稱 android -d Production -m true

然后重啟app,就可以看到更新提示啦
