java - 无法导入SDK DJI android

Question

我正在尝试integrate SDK into Application与 Android 工作室。我只是按照步骤操作，但我不知道是因为版本的原因还是我不知道...

我使用:

• Android 工作室:3.5.3
• x86 程序
• 大疆SDK

我无法运行该应用程序，并且在运行该应用程序时收到此错误:

我知道这是一个很长的错误，但我不知道它会是什么......

欢迎索取代码或屏幕截图

Answer 1

下面的行显示了错误的原因。由于该应用程序在模拟器上运行，因此它找不到 USB 配件。请尝试在物理设备上运行。
