title: Detect input from software or hardware keyboard
body: <p>I'm working in an Android app that must use a RFID tag reader. I'm using this reader as an extra device connected in my microUSB with an OTG wire. Android is detecting this device as an input keyboard. I would like to know if I can programatically detect when a user does an input with this reader. So basically I must differenciate the input from my softkeyboard or this reader. I searched a lot but I can't find a solution any help would be so appreciated. Thank you very much.</p>
