How to access scanning result from barcode scanner connected to Android device via USB port?

Question

An external Laser barcode scanner is connected to Android POS device. I need to access the scanning result in my application. How is it possible? Need support from Android OS version 2.3 onwards.

Answer 1

Most USB scanners connect via the HID profile, so Android should recognize it as a keyboard. The decoded barcode will be "typed" into the currently selected field.

If you'd like to capture the result without entering it into an editable field, see Handle barcode scanner value via Android device
