先看效果图吧：

1.大疆无人机官方文档地址：，我们做这个无人机开发1，需要先去大疆官网看文档，然后申请一个大疆账号，然后去申请appkey，注意这个appkey很重要。不申请的无法运行

2.配置环境，添加依赖，在app下面的builder.gradle

apply plugin: 'com.android.application'android {    compileSdkVersion 28    buildToolsVersion "28.0.1"    defaultConfig {        applicationId "com.example.administrator.testz"        minSdkVersion 19        targetSdkVersion 28        versionCode 1        versionName "1.0"        multiDexEnabled true        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"        ndk {            abiFilters 'armeabi-v7a'        }    }    buildTypes {        release {            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'        }    }    packagingOptions {        exclude 'META-INF/rxjava.properties'    }    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"    }}dependencies {    implementation fileTree(dir: 'libs', include: ['*.jar'])    androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {        exclude group: 'com.android.support', module: 'support-annotations'    })    implementation 'com.android.support:appcompat-v7:26.0.0-alpha1'    testImplementation 'junit:junit:4.12'    //====dividing    implementation 'com.android.support:multidex:1.0.1'    // dividing    implementation 'com.dji:dji-sdk:4.8.1'    implementation 'com.dji:dji-uxsdk:4.8.1'    compileOnly 'com.dji:dji-sdk-provided:4.8.1'}

2.清单文件，注意清单文件我写注释的地方，那个很重要，还有就是appkey，你们需要自己去注册

3.验证无人机环境

package com.example.administrator.testz;import android.app.Application;import android.content.Context;import com.secneo.sdk.Helper;/** * Created by wrs on 2019/6/4,10:47 * projectName: Testz * packageName: com.example.administrator.testz */public class MApplication extends Application {    private FPVDemoApplication fpvDemoApplication;    @Override    protected void attachBaseContext(Context base) {        super.attachBaseContext(base);        Helper.install(MApplication.this);        if (fpvDemoApplication == null) {            fpvDemoApplication = new FPVDemoApplication();            fpvDemoApplication.setContext(this);        }    }    @Override    public void onCreate() {        super.onCreate();        fpvDemoApplication.onCreate();    }}

4.无人机绑定注册

5.动态权限申请，广播注册

写到这里结束了，这里只是两个简单的使用，大疆无人机的官方demo更加的详细，大家可以参考官方的程序，我这个程序是精简化的代码，但是看起来稍微简化了一些，详细的还是建议看官方的代码，

遇到的坑！：

1.appkey没注册

2.清单文件，有一个intent广播意图是用于启动应用界面的，官方的那个activity什么都没有，你必须修改一下，不然就点击什么反应都没有，无法启动

3.连接状态，包括已连接和未连接，在refreshSDKRelativeUI里面，我想把这个状态弄出来，死活不行，大家如果想要这个状态，可以把这个activity作为主Activity，然后其他界面用fragment的方式进行，本例子没做这个功能，

4.拍照的时候，必须插入SD卡，不然无法返回scuess ，就是拍照失败的意思，然后，插入SD卡后，本例子必须设置一下拍照的模式，才可以成功，但是官方demo可以直接拍照，。这一点以后有机会研究一下，这个地方还没有优化，

5.有了sd卡，并且拍照成功后，其实在SD里面就已经存储了照片，在/根目录/DCIM/100MEDIA  这个目录里面

其他的 也没啥了  把这些代码复制一下，连上飞机，就可以控制了，但是在没这做这个之前，觉得还是很麻烦的，现在看很简单，最后联系方式qq：2494075190
