1) Don't know. Facebook has made an Android App. Get it from the Play Store. It might work on Nook.
2) Because apps have the same 'identifier'. So if a developer makes an app he/she names it
This identifier is usually the exact same for Nook Store and Play Store.
So Play Store doesn't know that the app is different. It just sees 'com.domain.appname' unique identifier and thinks it's the app from its own store.
Play Store will treat the app exactly as if it came from Play store. Just ignore it asking you to update or turn off update notifications for the app. It's in settings somewhere.
THANK YOU 5ivedom!!!
I appreciate the explanation! I just wanted to know.
The Google Play Facebook for Android.... it does work. And have figured out my assumption was correct, in that the Facebook for Nook app is nothing more than fancy icon that when clicked opens up Facebook Mobile in a browser. No push notifications.
Thanks again, 5ivedom, for taking the time to answer my questions!!
