So, my solution to getting the files on Android is the following:
1) Download the Game (1.5 version) and DLCs.
2) Install the Game.
3) Go into the files app (usually called My Files) and either search for a file called "ourlife.demo.apk" or go to the "internal storage" tab and then the "Android" tab in that and then the "data" tab in that to find it.
4) Once in "ourlife.demo.apk", go to the files tab (should be the only option) and then create a folder within that (just name it "game").
5) Finally, move each of the DLCs/Voice Pack .rpa files into this file ONE AT A TIME (doesn't work when you do it all at once, for some reason). Once you do that, just start up the game and it should all be installed. (I recommend checking the app as you do each one to ensure that it is installed).
