Is it possible to add Flavors to the new version of an already published App?
If yes, suppose the following senario:
I have a published app in Play Store (e.g. com.example.android). In the new version of the app I add (e.g. free and paid) Flavors. This addition changes the package name of the app to com.example.android.free and com.example.android.paid.
Suppose I publish only the com.example.android.free Flavor.
What will the link to the Play store be like?
https://play.google.com/store/apps/details?id=com.android.example (as it already was) or it will be renamed to https://play.google.com/store/apps/details?id=com.android.example.free
You can't change the package name of an already published app, you can however have two flavors free/paid, but one of them should have the original package name:
e.g.
free = com.example.android
paid = com.example.android.paid
which will mean the free app would update the currently existing one, and the paid app will be a new app on Google Play (with zero statistics and downloads).
the links to the 2 apps would be as expected: https://play.google.com/store/apps/details?id=com.android.example and https://play.google.com/store/apps/details?id=com.android.example.paid
If you want to enjoy the best of both worlds, look into [in-app-billing][1] to allow your users to download the app for free, and pay within the app to unlock premium features.
