Localization of the Online Android app

l10n
#1

Hi Cloph,

As we discussed on IRC, the Android app is now based the Online code, and
it lives in the online.git repo. You said that Weblate can handle
strings.xml directly which is great. There are two strings.xml to be
translated:

./android/lib/src/main/res/values/strings.xml
./android/app/src/main/res/values/strings.xml

We have pushed a few translations directly already (es, pt-BR, and
pre-existing tr).

Thanks,
Andras
