Please I need to check if there is a solution to a common problem.
I am not an experienced programmer in mobile apps. I am new in this field and I am an amateur who likes to design educational apps.
I want to publish my app on Google Play Store but not for free. The fee is small and I hope that students will be interested to buy and install my app on their Android phones and tablets but what I would like to happen is that one person buys my app and distribute it by sharing to other persons.
How can I disable this sharing and let people have only one option which is to download the app from the Play Store only?
