一身转战三千里,一剑曾当百万师。这篇文章主要讲述Android DJI Mobile-SDK 开发相关的知识,希望能为你提供帮助。
由于大疆的文档是英文的,看着不太舒服,虽然靠翻译插件进行翻译可也能看,但是来回的切换看比较麻烦,就搞一个中文的教程,基于SDK Version: 3.5.1(书到用时方恨少,后悔当年没好好学习英语)
开发准备
- 先去开发者中心注册账号
- 登录个人中心
文章图片
- 创建应用

开发
可以参考大疆的android文档 —— [ DJI ]
- 下载Demo,将Demo 中的lib项目导入自己的项目工程中
- 配置AndroidManifest.xml

- 手机连接遥控器
- 选择dmeo打开
- 连接飞机成功,点击open按钮,成功的话会显示画面
