What do I have to do? I downloaded the two archives but if I can see what needs to be translated for the "Locale" Archive, I don't undertand what to do for "Peerbet_src" Android packages. Can you lead me?
"Peerbet_src" is Android app sources, you have to translate "strings.xml" from it or get it here:
