When you submit a file, you can see multiple 'environments' to choose from. Some of them are 'Windows' and some of them are 'Android' environments (the one titled 'Android Static Analysis'). Anyway, when a user submits a file that has a file suffix *.apk, only the first 'Android' environment should be automatically checked, instead of the first one in the list.
There is quite a lot of follow-up work (also PHP, CSS, Twig related), if interested.
