you need to set the image and the text.
you do not need to set any data.
(intent has no effect, yet)
Ok, I figure out why was not working.
I tried all 4 intent with the result that all of them share the game instead of doing what the intent is made fore. I don't know how much sense is to make a button called "challenge your friend" and then, when you actually challenge the player, you will see the action to share the game instead of challenge (on the facebook messanger). This is super confusing. please, correct me if I'm wrong
I never played a game in the instant game platform, but I'm assuming that the name should change based on which action you are doing. If you challenge someone, then you should see "Challenge" instead of sharing lol
So, basically right now is possible just to share the game even if the plugin has 4 different options? lol...Is the Scirra team working on it? I don't know if it make sense to keep 3 actions in a plugin that doesn't works... This just make confusion and frustration I guess.
