I created an Android Game using Appwarp and now I want to connect players using facebook. I read the docs for a few hours and now I am uncertain where to go next. I understand Game Requests in facebook requires "presence on Facebook Canvas". How do you do that? My app is a game and is already released on the app store with random matchmaking enabled, why doesn't facebook recognise this app as a game?
I tried GameRequestDialog, but returns error only available to games.
For games without presence on facebook canvas I seem to understand you have to use ShareDialog (https://developers.facebook.com/docs/sharing/android#message-dialog) or AppInviteDialog (https://developers.facebook.com/docs/archive/docs/app-invites/android/)?
bottom line, What I really want is for a player to see a list of his/her friends click on it and be matched with that person in game with appwarp, how can I achieve this? Do I have to do something to get presence on the facebook canvas or is there another way?
EDIT : after more digging I realized Google's firebase push notifications devices to devices might be what i really want, unless someone thinks that is not feasible?
