For Nook, Samsung and Amazon, your app will work mostly unchanged. Ads and In App Purchases and Google Play Game Services will have to be accounted for still.
For IAP: Amazon has their own plugin for Corona SDK. Nook uses the Fortumo plugin and of course for Google, you would use the Google Play. Samsung has allowed using Google Play services, but they have recently announced that apps on their store must use Samsung SDK’s for things like IAP.
For Ads, Nook doesn’t allow them. Amazon does not like ads that promote apps for Google Play, so whatever ad service you use needs to recognize the platform you’re on and deliver Amazon compatible ads. There is an Amazon Ad plugin from the 3rd party plugin service that you probably should consider using that plugin.
For “Game Center” type activities, Nook uses Google Play Game Services, so that should be fine. Amazon should also allow use of GPGS but they have their own GameCircle that they would prefer you to use. Someone is building a plugin for it, but its not ready yet. If you want to use it now you can use Enterprise now.
Now for Samsung, they notified their developers that starting July 1, 2014, they will begin rejecting apps that do not use their SDKs. They offer SDKs for Ads, Game networking, and IAP. What is unclear and we are still researching, is if you just need to use one of these or all of them (if you use these features), what level of Google Play they will continue to support. As of today, Enterprise subscribers should be able to use the Samsung SDK’s to add support for your app.
