flutter 通过ota_update 实现安卓app内部更新

pub安装 ota_update

dependencies:
  ota_update: ^4.0.2

进行安卓相关配置

• 在android/src/main/res目录下新增xml文件夹
• 在xml文件夹下新增filepaths.xml以及network_config.xml文件
  • filepaths.xml

  <?xml version="1.0" encoding="utf-8"?>
  <paths xmlns:android="http://schemas.android.com/apk/res/android">
      <files-path name="internal_apk_storage" path="ota_update/"/>
  </paths>
  

  • network_config.xml(允许使用http的设置，如果是https就不需要进行这个配置)

  <?xml version="1.0" encoding="utf-8"?>
  <network-security-config>
      <base-config cleartextTrafficPermitted="true"/>
  </network-security-config>
  

• 在AndroidManifest.xml使用上述添加的两个文件

android:networkSecurityConfig="@xml/network_config"

<provider
    android:name="sk.fourq.otaupdate.OtaUpdateFileProvider"
    android:authorities="${applicationId}.ota_update_provider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/filepaths" />
</provider>

• 在AndroidManifest.xml中添加相关权限

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES"/>

以上在flutter实现安卓apk自动下载更新的相关配置完毕，剩下的就是具体APP页面上的相关逻辑提示下载实现了

• ota_update中的提供的下载例子

// IMPORT PACKAGE
import 'package:ota_update/ota_update.dart';

  // RUN OTA UPDATE 
  // START LISTENING FOR DOWNLOAD PROGRESS REPORTING EVENTS
  try {
      //LINK CONTAINS APK OF FLUTTER HELLO WORLD FROM FLUTTER SDK EXAMPLES
      OtaUpdate()
          .execute(
        'https://internal1.4q.sk/flutter_hello_world.apk',
        // OPTIONAL
        destinationFilename: 'flutter_hello_world.apk',
        //OPTIONAL, ANDROID ONLY - ABILITY TO VALIDATE CHECKSUM OF FILE:
        sha256checksum: "d6da28451a1e15cf7a75f2c3f151befad3b80ad0bb232ab15c20897e54f21478",
      ).listen(
        (OtaEvent event) {
          setState(() => currentEvent = event);
        },
      );
  } catch (e) {
      print('Failed to make OTA update. Details: $e');
  }
