Component used: Navigation Version used: 2.6.0-alpha01 Devices/Android versions reproduced on: Galaxy S21 5G

Hello! It seems like some users are facing very rare crashes with the following stack trace.

I'm unsure what the right direction would be to investigate and fix it. May it be somehow related to some rare Navigation framework internal issues?

Seems to be a DNS problem with systems that have 'obtain DNS server address automatically'. Changed my system to a manual setting and the browser etc now work. SDK 2.2 didn't seem to mind the auto setting though.

Could you please describe how/where you changed your system to a manual setting?

il...@gmail.com <il...@gmail.com> #4Sep 18, 2022 12:40PM

Based on its date, this issue was originally reported before Android 2.3. Because of the many changes that existed in Android 4.x compared to previous versions, it's very likely that this issue doesn't exist in recent versions of Android like 4.2.2 or newer. Because of the high likelihood that this issue is obsolete, it is getting closed automatically by a script, without a human looking at it in detail. If the issue still exists on a Nexus 4 or Nexus 7 running Android 4.2.2 and is not related to Google applications, please open a new report accordingly.

Branch: androidx-main

commit c5ff8b06a002ff7fcd89466b885f6ec930148d7f
Author: Jeremy Woods <jbwoods@google.com>

Prevent accidentally removing active fragments

It is possible with saving and restoring state to accidentally make
fragment manager mark an active fragment as inactive.

This results in a failed restore after a config change.

We should only make FragmentStateManagers that are active inactive. This
ensures that active and inactive calls are 1 to 1.

RelNote: "Fixed a bug in FragmentManager where saving and restoring in
the same frame could cause a crash."
Test: Added FragmentManagerTest
Bug: 246519668
