I'm designing an Android app in which I need a feature that can enable me to do
- Update app of users for new features even though they are not updated from Playstore.
- With out app update in Playstore I can add/remove new features.
Ex: I had seen apps like Telegram and Google chrome in my old phone. I hadn't updated those apps from almost 2years but many new features are added to them (may be core features not added). I also checked the versions of those apps, still they are on older versions.
How can I add this type in app update feature in my app?
