ViewPager2 + FragmentStateAdapter + offscreenPageLimit = 1 => onResume not called

Question

I'm having an issue with my ViewPager, but I don't know why and how to fix it.

So I have a ViewPager2 on which I'm using a FragmentStateAdapter. This pager contains approx 10 pages (not really important). On that ViewPager, I also have

viewPager.offscreenPageLimit = 1

From what I understood, when using ViewPager2 + FragmentStateAdapter, onResume should be called on the visible fragment whenever the selected page changes.

However:

• Fragment 1 -> Fragment 2 => onResume/onPause not called
• Fragment 2 -> Fragment 3 => onPause called on Fragment 1 and onResume called on Fragment 3
• Fragment 3 -> Fragment 4 => onPause called on Fragment 3 and onResume called on Fragment 4
• And so on.

So the issue here is onResume is not called on Fragment 2 when I go from Fragment 1 to Fragment 2.

If I remove

viewPager.offscreenPageLimit = 1

Then this fixes the issue. However, I don't understand why... Is it normal? Is it a bug? Am I missing something?

Thank you guys in advance.
