I don't know, if is ok because I've never tried due today. Maybe I'll do when the translation is incorporated, if there is a trial, to see if some corrections needed.
I mentioned that a lot of strings which are dublicated, as "starred"(if I remember well). Can' t you use the same string keyword (@string/hours for eg) to multiple places on you code or layout widgets, to don't need to rewrite them over and over? I'm sure that as an experienced developer maybe you have your reasons for doing this(I have some basic knowledge on android developion only), but I mention it in case you've missed this future.
