I have a Russified version of 68.1, but I haven't converted it for Android. I think that if I do, it's unlikely to work. There's some compatibility issue here, probably. I'll try to install another emulator that has an environment for smartphones Xiaomi with your variant OS. It will take some time.
But it would be best if the author packed the files with the translation into his own APK file.
