Connecting a USB device to an Android emulator is a common challenge for developers testing USB host features, serial communication, or specialized peripherals like external cameras and medical equipment. While the standard Android Virtual Device (AVD) from Android Studio does not offer a simple "plug-and-play" button for USB passthrough, several advanced methods allow you to bridge physical hardware to your virtual environment. 1. The Official USB Passthrough Method (QEMU) connect usb device to android emulator better
Your app needs to read data from a USB barcode scanner, a thermal printer, a game controller, an external DAC, or an Arduino board. The emulator runs perfectly—until you plug in the USB device. Nothing happens. | Method | Latency (ms) | Hotplug
