Hey there, you need to extract the .zip file contents to the following location: "/Android/data/com.dbpanda.betweenhumanity/files/game/". The walkthrough.rpyc file needs to be in that game folder in the end for it to work automatically.
By the zip files contents do you mean the mods or the games because if you mean the mods I don't know where to find Android/data/com.dbpanda.betweenhumanity/files/game
You need to download a file manager app on your android phone and then navigate to that folder, should be fairly straightforward afaik :). Zip file contents refers to the mod.
