: This method doesn’t yet support isochronous transfers (webcams, audio interfaces) on older emulator versions. Method 2: Native USB Passthrough (Emulator 31.3.10+) Newer emulator versions include a dedicated USB passthrough flag. This is the closest you’ll get to a physical USB host. Step 1: Launch the emulator with USB passthrough From the command line:
: On macOS, you may need to run Android Studio with sudo due to stricter IOKit permissions. Method 3: Using virtual-usb (For Advanced Hardware Emulation) Google’s virtual-usb manager (part of the emulator tools) lets you bind a host USB device to a virtual USB controller inside the AVD.
The good news? . It’s not plug-and-play, but with the right setup, the emulator can treat your USB gadget just like a real phone would. connect usb device to android emulator
emulator -avd YourAVDName -usb-passthrough "vendorid=0x1234,productid=0x5678" Find your device’s vendor/product ID using lsusb (Linux/macOS) or Device Manager → Properties → Details → "Hardware Ids" (Windows). Your app will now see the USB device exactly as if it were plugged into a real handset. Use the standard UsbManager API:
: If you’re testing a custom USB peripheral, use adb shell dmesg inside the emulator to check if the kernel sees the device—it’s the fastest way to know if your passthrough worked. : This method doesn’t yet support isochronous transfers
val manager = getSystemService(Context.USB_SERVICE) as UsbManager val deviceList = manager.deviceList deviceList.values.forEach device -> if (device.vendorId == 0x1234 && device.productId == 0x5678) manager.requestPermission(device, ...)

Now go unchain your development from physical hardware. Your desk (and your wallet) will thank you.
