我无法运行ImportSDKDemo，无法加载ffmepg。

您好，无论我使用的是什么版本的sdk（24、26、28），我都无法运行此演示。

我已经安装了ffmpeg

Answer 1

Android ImportSDKDemo与本教程相关：https://developer.dji.com/mobile-sdk/documentation/application-development-workflow/workflow-integrate.html#android-studio-project-integration，您可以按照它学习如何导入Android SDK。

如果只想运行该演示，只需从Github下载整个项目：https://github.com/DJI-Mobile-SDK-Tutorials/Android-ImportAndActivateSDKInAndroidStudio，并替换为AndroidManifest.xml文件中应用的App键即可直接运行它。无需安装ffmpeg。它对我有效。

感谢您的帮助和时间。但是我需要自己构建它，因为我想扩展它以向Spark发布虚拟操纵杆命令。

或者您是否可以建议一个更好的示例来扩展虚拟游戏杆命令？

谢谢！
