Artifact used:
- androidx.viewpager2:viewpager2:1.0.0-alpha04

I noticed that ViewPager2 sometimes crashes with the following stack trace. Currently, I have not figured out how to reproduce the error frequently, so I will attach the procedure/sample project for reproduction later.

Change the way to detect mismatch between POJO and query

This fixes cursor mismatch warnings with expandProjection.

commit bdde5a1a970ddc9007b28de4aa29d60ffa588f08
Author: Yigit Boyar <yboyar@google.com>
Date: Thu Apr 16 16:47:05 2020

Re-factor how errors are dismissed when query is re-written

This CL changes how we handle errors/warnings if query is
re-written.
There was a bug in expandProjection where we would report warnings
for things that Room already fixes automatically (

b/140759491

).
The solution to that problem (I7659002e5e0d1ef60fc1af2a625c0c36da0664d8)
solved it by deferring validating of columns until after re-write
decision is made. Unfortunately, this required changing PojoRowAdapter
to have a dummy mapping until it is validating, make it hard to use
as it does have a non-null mapping which is not useful.

This CL partially reverts that change and instead rely on the log
deferring logic we have in Context. This way, we don't need to break
the stability of PojoRowAdapter while still having the ability to
drop warnings that room fixes. This will also play nicer when we
have different query re-writing options that can use more information
about the query results.

Bug: 153387066
Bug: 140759491
Test: existing tests pass

Hi! I have successfully created a demo project which can reproduce this issue. Please check the following repo and I hope it helps to resolve the issue.

[UPDATE]
This issue still exists on ViewPager2 v1.0.0-alpha06 with RecyclerView v1.1.0-beta01.

I can confirm I can repro this and will try to provide a workaround / fix soon.
Big thanks for the sample app, repro steps and research info. Super appreciated!

jg...@google.com <jg...@google.com> #8Jul 16, 2019 03:53PM

The easiest workaround would involve copying FragmentStateAdapter and FragmentViewHolder into your project, and in FragmentStateAdapter adding ensureFragment(holder.getAdapterPosition()) as the first line of placeFragmentInViewHolder method. Attached as a patch to your sample app.

We'll work on a proper fix. Might unblock you in the meantime though. Thanks again for reporting and a sample app.

Fix for FragmentStateAdapter transient state issue

Fixes a crash when a ViewHolder which has gone through
onFailedToRecycleView is shown again violating Adapter's design
assumptions.
