As far as I know, the game on Android doesn't work, Joiplay doesn't run the game and this is out of Runey's control, HH developers are trying to talk to Joiplay developers to resolve the situation

If, and only if, you have a working version of Joiplay (previous versions used to work, current version does not),  you can update by using the patch file, just like the PC players.

If you used to play with the APK... You have my sympathy. The current version of HH has too much content to fit in the APK limits. By, like, an order of magnitude. You can't fit an elephant into you cabin baggage. no matter how hard you squeeze it.
