You could use Google Translator Toolkit, which helps speeding up android translations and concurrent edits from many users.
It's free and simple to use, also it pre-translates all strings in the target languages, allowing a human translator to change only what's incorrect.
I already uploaded your file to test it and here it is what you see:

The only "drawback" is that you have to explicitly invite users (just need their gmail address) to allow them to translate.

Please check it out.

Thank you
