[Android] Android translations

[Christoph Miebach]

Hello!

Using the transifex indent on request of M.T. (polish). I removed the untranslatables although they are provided by the transifex files.

Next updates should be nice little diffs that way. In other words: next translations will be similar, so check carefully ;-)
