我从 github ( https://github.com/dji-sdk/Mobile-SDK-Android ) 下载了新的 SDK 演示 (v3) 并使用 Android Studio (1.5.1) 打开项目。导入进展顺利，一切看起来都很好。

除了 dji 应用程序键之外，我没有更改代码或设置，但是当我尝试启动应用程序时（在带有 Android 6 的 Nexus 9 上）我在 android 监视器中收到以下消息：

并且应用程序将直接在 android 平板电脑上关闭。任何人都可以帮助我并告诉我我做错了什么吗？为什么不能只下载并启动 sdk 演示？

提前致谢！问候

问题是应用程序中的 Android 版本，因为 SDK Lib 是使用 android 级别 22 构建的，而应用程序是使用 android 级别 23 构建的。

将应用程序减少到版本 22 后，应用程序正在运行！

请在DJI 开发者用户中心申请 App Key 时查看识别码，应该是com.dji.sdk.sample。更多信息，请查看DJI Android SDK Github Page，您可以按照那里的指南进行操作。希望这有帮助！
