Question

I have the activity A where I can navigate to A->B->C->D

In Activity D I have a button in which if user’ll press this button, it’ll go to Activity A. Here I’ll create a new instance where user can update value here.

I finish the activity, it’ll Go To Activity D,from Activity D user’ll press Back Button
D->C->B->A and will come to Activity A.

I need to show the updated value in Activity A, how can I update value in ‘Activity A’ ?

Answer 1

You’re going to want to have a whole bunch of startActivityForResult()s and basically chain them from D back to A.

See here: How can I pass values between Activities on Android?

Alternatively, you could store the value as a SharedPreferences and just look it up later, once you return to the original Activity.
