NPE in MvpDelegate.onAttach in 1.5.5

[asfdfdfd]

MvpAndroidXFragment is just Kotlin clone of MvpAppCompatFragment for AndroidX — https://gist.github.com/asfdfdfd/87552746c9182f6b7311f3d9ce6272a6, but this issue has appeared sometimes before migrating to Android X.

Here you could find shared Crashlytics record — http://crashes.to/s/d4ea6c01c8b

Also i'm attaching txt dump of this record to the issue — com.mirrorai.app_issue_1975_crash_5C1233CA02D700016492338D211553E3_DNE_1_v2.txt

I could not reproduce crash on my devices. It is super rare but i observe it from time to time.

Please provide your implementations of fragment and presenter.

Actually stack trace is not pointed to one of my fragments and presenters (except of MvpAndroidXFragment that is attached).

But it is pointed on androidx.fragment.app.FragmentStatePagerAdapter.

I have one FragmentStatePagerAdapter. Do you want implementation of Fragment/Presenter where adapter is placed or one of adapter's child or all children of adapter?

Do you trying to update adapter items? FragmentStatePagerAdapter have some old bug with tags of restored fragments https://issuetracker.google.com/issues/36956111. Maybe this will help you https://github.com/inloop/UpdatableFragmentStatePagerAdapter

Do you trying to update adapter items?

No. I replace entire adapter.
