Strange Result while Scanning

Hey guys, so during an nmap scan i came across something really strange that i hadn’t seen before and i haven’t been able to find much info on it - from obvious info looks like an android/meterpreter payload, but i cant even begin to wonder what its doing there
Was wondering if anyone could maybe explain please?
