Question

I'm trying to integrate SDK into Application with Android studio. I just follow the steps but i don't know if its because of versions or i don't know...

I use:

• Android studio: 3.5.3
• Program x86
• Dji sdk

I'm unable to run the app and I receive this errors when i run the app:

I know it's a very long error, but i don't know what can it be...

Feel free to ask for the code or the screenshots

Answer 1

The line below shows the reason for the error. Because the app is running on an emulator, it can't find a USB accessory. Please try running on a physical device instead.
