In some Android devices i got this erros :
Unable to find nmap-services! Resorting to /etc/services
Unable to open /etc/services for reading service information
This happen with Android 8, 8.1 and Android P
In lower versions it is working well
I'm using precompiled binaries V. 7.31 from : https://github.com/kost/nmap-android/releases
I have read too about nmap --datadir but can't make it works.
Any Idea ?
P.s : The tests performed on Emulators and Real devices too
Solved by copying Nmap extra data like "services,scripts etc. into main nmap binary directory"
