Google does not restrict the ability to sell items through your app; that's Apple. You can implement a store in your app with purchases if you want, without using Google's payment system. And many such apps exist in the Play store.
What you can't do in an app in the Play store is implement your own app store and load arbitrary apps. And Amazon forces you to install the full Amazon app including its app store, rather than offering a standalone version of Amazon Video.
Amazon likely does this because people care enough about Amazon Video to jump through hoops to get it, and once people have jumped through those hoops, Amazon can then try to get them to use the Amazon app store instead of Play.
And their forcing you to install an app store shim that asks for ALL/ALL application rights is why they got booted to my "snoopy vendors only" Android profile: the one with zero human contact information. For those of us willing to put the time into it I'd love a cleaner way to containerize apps and firewall off personal information.
An Android for Work profile runs on Android's new containerization feature (derived from Knox). You'll either need a separate Apps account or use a custom Work Policy Controller[1] as a lightweight app container.
I'd not be surprised if someone has built something marketable on this stack already.
That's interesting, I didn't know you could do that with Android. That is a hell of an awesome feature, coming from an iOS user. IMO, we'll almost be forced to maintain multiple identities in the future, and it's good to hear that Google is getting a jump on that trend.
It makes sense, of course, considering that this approach will let Google -- but no one else -- know who all those identities point back to.
It's not in every Android distribution: for instance Samsung doesn't include it on their phones, but profiles are one of the benefits of running stock Android on a Nexus phone.
If you're willing to root your phone there's an xposed privacy framework that inserts itself between the OS and snoopy apps to allow finer access control.
Unlike in the iTunes App Store, that restriction is only on items and subscriptions that can only be consumed inside the app. That's why Amazon can continue to sell music and Netflix can continue to sell subscriptions in their apps. There is nothing stopping Amazon from offering Prime Instant Video through the Play Store with no modifications.
