I’m working on a feature in my app that allows the user to enter information inside 4 different fragments and I want to store that information and in the last fragment I have a button that will store all of the user input to a database. How would I go about doing that? I tried Bundle() but I keep getting null pointers. How can I save user input across multiple fragments not just one fragment to the other.

Thank you for this footage. When I rotate my phone two fragments are overlapped. Would you please let me know the reason?

Why no one explaining how can we change text in fragment from related viewmodel from mainactivity????
no one knows?

I don't think its a good design for fragments to know about each other. A better design would be the using the Activity to start the DetailFragment.

pro tip: if like me you are have a lot of fragments and you are finding it complicated transferring data among them all use Singleton pattern
