TIP for Finnish Jolla users. Might of course work for others as well.

The android comparability layer is so well build, that it can "fool" even banking applications. Osuuspankki Pivo-lompakko and their OP-Mobiili both work on Jolla device. I once tried this with Bluestacks and that didn't work. But as said this does in Jolla. I didn't want to draw the APK's from any site or unofficial store because of being afraid of risking some really sensitive information. So i installed the applications on my Android phone from Play store and then draw the APK from it to my computer and then transfered it to my Jolla. This method that has already pointed out works like a charm on this as well and you can be sure that the APK has nothing "added".
