I would like to create an App with mp3s, when the app is free, the user can listen to the music with ads, when the user purchase the app, he can listen to music offline.
My first question is:
1)Can 1 single app using your framework enable us to pass from free to premium? Or does this requires 2 apps?
2)Can Mp3s be hosted on a website when the app is free and on the mobile phone itself when premium?
3)To pull mp3s from a website, do I need to put some kind of cross domain code in the server?
4)If a user wants to purchase a song he ears, can your framework help us with the purchase/download of the song?
