SDK文件结构如下:
|-- [email protected]
|-- DEMO //uni小程序SDK示例DEMO
|-- SDK //uni小程序SDK
|-- assets // assets资源文件
|-- libs //依赖库
|-- res // 资源文件
|-- src //微信分享支付需要的activity
|-- proguard.cfg //混淆配置
查看Flutter项目中android/app目录中是否存在libs文件夹,没有就创建。
将 [email protected]/SDK/libs 中相应的依赖复制到 项目 android/app/libs/
libs 文件夹依赖库可根据功能需要进行增加或删除,除视频、地图、分享、支付、登录、直播pusher 等 SDK,只集成以下基础模块就可使用:
uniMPSDK-V2-release.aar //必须集成,uni小程序sdk引擎需要
uniapp-v8-release.aar //必须集成,uni-app引擎需要
breakpad-build-release.aar //必须集成,breakpad用于采集系统崩溃日志
sqlite-release.aar
base_oaid_sdk.aar 必须集成 注意(3.3.8版本的SDK及以下版本请集成oaid_sdk_1.0.25.aar)
messaging-release.aar
iBeacon-release.aar
fingerprint-release.aar
contacts-release.aar
Bluetooth-release.aar
[email protected] //必须集成
1,将[email protected]/SDK/assets/ 目录下的所有文件复制到 Flutter项目中android/app/src/main/assets/。(main目录下没有assets文件夹则自行创建)
2, Flutter项目中android/app/src/main/assets 目录中创建 apps 文件夹,用于放置 uni小程序打包发行的程序。
在小程序项目的 manifest.json 内获取并使用 uni-app 应用标识(AppID),也是我们之后指定操作小程序的标识。
将打包好的uniapp小程序复制到apps文件下,apps文件夹结构必须如下:
├── apps
│ ├── __UNI__xxxxxxx # 小程序1
│ │ └── www
│ │ │ └── ... #小程序编码
│ ├── __UNI__xxxxxxx # 小程序2
│ │ └── www
│ │ │ └── ... #小程序编码
将 [email protected]/SDK/proguard.cfg 复制到Flutter项目中android/app/ 中。
