Hi guys,
I have 2 Activities, and 1 fragment inside one of them.

`MainActivity`: Contains a Fragment UserFragment, the fragment display data of a User, the data is fetched from the SharedPreferences.
EditUserActivity :Edits the data of the user, and once editing is done, this activity calls finish() and we go back to MainActivity, which displays UserFragment

When returning to UserFragment, the data displayed is the old data for the user (the unedited data)

I can think of 2 ways to make the fragment display fresh data, can anyone think of a smarter way, or explain which way below is better in terms of design?

1. Make UserFragment start EditUserActivity with startActivityForResult , and return a success or failure code, if success we do some data refresh.
2. Make UserFragment terminate itself once we navigate to EditUserActivity, and make EditUserActivity launch MainActivity with UserFragment on a backpress or successful save.
Even if there is a way that is tricky and should not be in production i would like to know as I want to expand my skills please, thank you! 🙂

Maybe, in onResume of UserFragment, get info of user in SharedPreferences is the best option

Genius my friend, btw it is preferrable to do it in onStart as there might be a phone call/etc and then there will be additional call to render the UI

@Ofir Bar what about onViewCreated?

@Hitender Pannu
My logic was initially at onViewCreated, it didn’t worked, as if I return from EditUserActivity to MainActivity, UserFragment won’t call onViewCreated

[Hitender Pannu]

Are you sure, because if onStart is getting called that means view was destroyed and onViewCreated should get called.

@Ofir Bar you try using this library, so the idea is to have a shared viewModel between activities like it's there for fragments.

I don’t agree that the View was destroyed, it was stopped, through a call to onStop()

Only after that we have onDestroyView() and onDestroy()

I think starting EditUserActivity with startActivityForResult is a good way.
