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

  • 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

添加SDK所需要的权限

<!-- SDK 需要的权限 -->
    <uses-permission android:name="android.permission.BLUETOOTH" />
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
    <uses-permission android:name="android.permission.VIBRATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

    <uses-feature android:name="android.hardware.usb.host" android:required="false" />
    <uses-feature android:name="android.hardware.usb.accessory" android:required="true" />

配置key以及服务

<application

        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

        <meta-data
            android:name="com.dji.sdk.API_KEY"
            android:value="自己应用申请的key" />
            
    <!-- 以下是官方dmeo默认的配置 -->
        <service android:name="dji.sdk.sdkmanager.DJIGlobalService" />

        <service android:name="dji.internal.geofeature.flyforbid.FlyforbidUpdateService" />

        <!-- Required for receiving GEO system pushing. -->
        <service android:name="dji.sdk.sdkmanager.GeoSyncFileService"/>

        <activity
            android:name="dji.sdk.sdkmanager.DJIAoaControllerActivity"

                <action android:name="android.hardware.usb.action.USB_ACCESSORY_ATTACHED" />
            </intent-filter>

            <meta-data
                android:name="android.hardware.usb.action.USB_ACCESSORY_ATTACHED"
                android:resource="@xml/accessory_filter" />
        </activity>
        
     <!-- 以上是官方dmeo默认的配置 -->
 
        <activity android:name=".MainActivity"
