Android Studio上的DJI Mobile SDK无法工作: FPVController: DJI‘t load lib
我对我在eclipse上开发的Android Studio SDK感到沮丧，但时不时地，努力迁移到Android Studio。我无法开始使用Android Studio。
我正试图在Android Studio上实现一个名为"PlaybackDemo“的DJI演示。我已经让它在Eclipse上工作了，但是Android Studio版本不能工作。应用程序会像预期的那样启动DJIAoaActivity，然后启动DroneSelectionActivity，但当你选择无人机的类型时，PlaybackProtocolActivity不会启动，应用程序会崩溃。我在LogCat上得不到PlaybackProtocolActivity所期望的OnGetPermissionResult。
我总是得到以下错误：

从日志中可以明显看出。感兴趣的线：
int dji.midware.natives.FPVController.native_setIsNeedPacked(boolean) (尝试过Java_dji_midware_natives_FPVController_native_1setIsNeedPacked和Java_dji_midware_natives_FPVController_native_1setIsNeedPacked__Z) )没有实现
java.lang.UnsatisfiedLinkError
我的猜测是:您已经链接了x86本机库，但没有为您的手机使用的处理器链接本机库。本机库的诅咒:您需要为您打算在其上运行的每个处理器预编译它们。
我不熟悉Eclipse上的NDK开发。如果您使用的是Android Studio，那么每个处理器家族都会有单独的构建目标，另外还有一个构建目标，用于为您选择支持的所有处理器构建本地库并将其包含到单个APK中。Eclipse大概有一些等价的概念，可以在某个地方构建目标。

对我来说，我是一个Android Studio的家伙，我遇到了一个更严重的问题。当我试图在Android Studio中打开PlaybackDemo，并在项目导航器上选择"Android“选项卡时，没有显示任何内容。似乎项目结构不正确，不适合Android Studio。
另外，我刚才看了一下PlaybackDemo，听说是用DJI SDK2.4开发的？这个版本比当前的3.1.1版本要老很多。看起来像虫子一样。
顺便说一句，如果你真的想尝试在Android Studio上使用DJI Android SDK，我建议你看看这个导入DJI SDK to Android Studio教程，它很适合我。
