react-native-upgrade-android

React Native的版本升级插件(仅是android), react-native版本需要0.17.0及以上

如何安装

1.首先安装npm包

npm install react-native-upgrade-android --save

2.link

自动link方法~ npm requires node version 4.1 or higher

npm link

link成功命令行会提示

npm info Linking react-native-upgrade-android android dependency

手动link~(如果不能够自动link)

#####Android

// file: android/settings.gradle
...

include ':react-native-upgrade-android'
project(':react-native-upgrade-android').projectDir = new File(settingsDir, '../node_modules/react-native-upgrade-android/android')
// file: android/app/build.gradle
...

dependencies {
    ...
    compile project(':react-native-upgrade-android')
}

android/app/src/main/java/<你的包名>/MainActivity.java中,public class MainActivity之前增加:

import com.lenny.modules.upgrade.UpgradeModule;

如果react-native-版本 <0.18.0 .addPackage(new MainReactPackage())之后增加:

.addPackage(new UpgradPackage())

如果react-native-版本 >=0.18.0 在new MainReactPackage()之后增加

,new UpgradePackage()

如何使用

引入包

import Upgrade from 'react-native-upgrade-android';

API

Upgrade.init()

// 使用前必须初始化

类似如下:

componentDidMount() {
  const {
    isSet,
  } = this.props;
  if (Platform.OS !== 'ios') {
    Upgrade.init();
  }
}

Upgrade.startDownLoad(downloadUrl, version, fileName)

开始下载

// 参数信息
  downloadUrl: 下载apk地址(绝对地址)String
  version: 要下载的版本号 (防止重复下载)String
  fileName: 保存的文件名 String

添加监听

类似如下:

componentDidMount() {
  const {
    isSet,
  } = this.props;
  if (Platform.OS !== 'ios') {
    Upgrade.init();
    DeviceEventEmitter.addListener('progress', (e) => {
      if (e.code === '0000') { // 开始下载
        this.setState({
          isLoading: true,
        });
      } else if (e.code === '0001') {  // 下载中,更新进度条
        this.setState({
          fileSize: e.fileSize,
          downSize: e.downSize,
        });
      } else if (e.code === '0002') { // 下载完成
        this.setState({
          fileSize: e.fileSize,
          downSize: e.downSize,
        });
      }
    });
  }
}
