DJI无人机程序开发

步骤

1、build.gradle中引入dji包

apply plugin: 'com.android.application'

android {

    ...
    defaultConfig {
        ...
    }

    ...

    packagingOptions{
        doNotStrip "*/*/libdjivideo.so"
        doNotStrip "*/*/libSDKRelativeJNI.so"
        doNotStrip "*/*/libFlyForbid.so"
        doNotStrip "*/*/libduml_vision_bokeh.so"
        doNotStrip "*/*/libyuv2.so"
        doNotStrip "*/*/libGroudStation.so"
        doNotStrip "*/*/libFRCorkscrew.so"
        doNotStrip "*/*/libUpgradeVerify.so"
        doNotStrip "*/*/libFR.so"
        exclude 'META-INF/rxjava.properties'
    }
}

dependencies {
   ...
    implementation ('com.dji:dji-sdk:4.9')
    compileOnly ('com.dji:dji-sdk-provided:4.9')
}

2、Application中初始化Helper
在使用dji的所有函数之前，需要加载SDK classes，在Application里调用。

    @Override
    protected void attachBaseContext(Context paramContext) {
        super.attachBaseContext(paramContext);
        MultiDex.install(this);
        com.secneo.sdk.Helper.install(this);
    }

注意：该方法是梆梆安全的加固库方法，跟AndroidX不兼容，在AndroidX的工程中无法使用。

3、在AndroidManifest.xml中赋予权限

    <!-- SDK permission requirement -->
    <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-permission android:name="android.permission.WAKE_LOCK"/>
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>
    <uses-permission android:name="android.permission.RECORD_AUDIO"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
    <uses-permission android:name="android.permission.READ_PHONE_STATE"/>

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


    <application
        android:name=".MyApplication"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
            <intent-filter>
                <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>

        <meta-data
            android:name="com.dji.sdk.API_KEY"
            android:value="your api key"/>

        <!-- Required for receiving accessory attachment events.
            This is necessary for product when connecting over USB. -->


    </application>

4、赋予所有需要的权限
需要手动赋予所有权限，然后才能使用DJI SDK的其他方法。

5、调用DJISDKManager的registerApp()方法注册
传入注册回调，里面有注册成功与否、遥控器连接和断开、组件连接回调。

DJISDKManager.getInstance().registerApp(MyApplication.getInstance(), new DJISDKManager.SDKManagerCallback() {
                        @Override
                        public void onRegister(DJIError djiError) {
                            
                        }

                        @Override
                        public void onProductDisconnect() {

                        }

                        @Override
                        public void onProductConnect(BaseProduct baseProduct) {

                        }

                        @Override
                        public void onComponentChange(BaseProduct.ComponentKey componentKey, BaseComponent baseComponent, BaseComponent baseComponent1) {

                        }
                    });
