Nested scrolling works partially (as per http://b/122818889 ). Let's discuss if we need full support and if so make sure it works.

Hi!
What is 'partially' exactly?
How do I see it?
Thanks!

As of now:
- Nesting scroll views with a scroll direction perpendicular to the ViewPager2's orientation inside ViewPager2 works
- Nesting scroll views with a scroll direction parallel to the ViewPager2's orientation inside ViewPager2 does not work
- Nesting scroll views with a scroll direction perpendicular to the ViewPager2's orientation inside ViewPager2 works

Horizontal ViewPager2 not correctly working into a vertical RecyclerView
Set a setNestedScrollingEnabled to the RecyclerView into the ViewPager2 (across reflection) resolves the problem

ageevvalentin@gmail.com, could you provide a sample app? I'd like to learn more about the circumstances that cause the problem; putting a clean ViewPager2 inside a clean RecyclerView seems to work fine, so there must be other factors involved.

Added a patch for androidx-master-dev that demos a horizontal ViewPager2 inside a vertical RecyclerView.
Verified that it works correctly on a:
- Nexus 4 emulator with API 17
- Nexus 5X emulator with API 28
- Pixel 2 device with API 29
To reproduce:
- Check out the Android Jetpack source (at commit 256899f482ff85cddfb050f37550be7b5ec927ef) (see steps in [1])
- Apply the patch (`git apply 0001-Add-sample-where-a-horizontal-ViewPager2-is-nested-i.patch`)
- Build and install viewpager2's integration-tests app: `./gradlew viewpager2:integration-tests:testapp:installDebug`
- Run it
Closing the issue for now, but please reopen if you have a minimal reproduction app

Re-opening as requested by a few users. Narrowed down the focus to nested scrolling elements with the same scroll direction.

Any progress on this? (only talking about the "same scroll direction" issue)
I searched a lot for workarounds on Google and SO, but it seems no one really found a suitable solution yet.
The thing is that all other VerticalViewPagers out there have other problems that are similarly annoying. Most of them revolve around touch issues like "What's a click and what's a swipe" or "what's the fling threshold to snap to the next page".
So if someone knows of a working sample of VerticalViewPagers, I'd be happy to see a link :)

Description
Version used: 1.0.0-alpha11
Devices/Android versions reproduced on: Nexus 5X API 27
I've implemented conditional navigation for my login flow as described in this SO post:
Now everything appears to be working, however after being navigated to the login screen and successfully logging in then navigating back to the main screen, on rotation the app crashes with the error: "java.lang.IllegalStateException: unknown destination during restore".
I've created a SO post containing the full error and navgraph for my project:
I've also reproduced the error in this sample app:
For a bit of further information it appears this crash started to occur in version 1.0.0-alpha08.
