How to restore activity data after navigating back from child activity?

Question

After this code in MainActivity:

Intent intent = new Intent(this, OtherActivity.class);
startActivity(intent);

then when a button is clicked in OtherActivity NavUtils.navigateUpFromSameTask(this); happens, so the app returns to MainActivity. But I don't think the data is restored from previously, and I don't think it should've been destroyed because onDestroy() wasn't called right?

Can you share what NavUtils.navigateUpFromSameTask(this); does? maybe it starts a new instance of your MainActivity instead of going back! — Mohamed Hamdaoui, Nov 23 '17 at 20:07

The answer is here: Returning from an activity using navigateUpFromSameTask()

android:launchMode="singleTop" in the manifest prevents a new instance of the activity from being created.
