Generic HID on Android device

MartinD

Hi,
I want to read and write generic HID USB device on Android in my Qt 5.11 app. What are the options?

Any API that can directly interface with generic HID USB device?
libusb? Is it possible to use it in Qt app for Android?

Hi,

What device are you targeting ?
What kind of device do you want to communicate with ?

I want to connect USB device designed by myself (it is USB generic HID device - one interrupt in and one interrupt out endpoint) to some Android tablet - I haven't chosen one yet. Some cheap one probably...

hi @martind ,
as far as I know, USB devices is not something that is supported out of the box for Qt on Android

Taking a quick look at the Android developer page, I found the class UsbDevice
https://developer.android.com/reference/android/hardware/usb/UsbDevice

So it should be possible, as long as your USBDevice itself is registered in the OS.

My guess is you'll have to write some native code to access it correctly.
