created issue #1

Dec 30, 2015 09:23AM

Library used (support-v4, appcompat-v7, ...):
compile 'com.android.support:recyclerview-v7:23.1.1'
compile 'com.android.support:appcompat-v7:23.1.1'
Version used:
Theme used:
default when created new project.
Devices/Android versions reproduced on:
Nexus 5 with Android 6.0.1

- Relevant code to trigger the issue.
<RelativeLayout
xmlns:android="

http://schemas.android.com/apk/res/android"
xmlns:tools="

http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">

<android.support.v7.widget.RecyclerView
android:id="@+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:nestedScrollingEnabled="false"
/>
</RelativeLayout>

- A screenrecord or screenshots showing the issue (if UI related).

not needed. it crashes.

Weird thing is that it doesn't crash in case I do this in code:

RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
recyclerView.setNestedScrollingEnabled(false);

Attached a sample project to show the issue.

Also attached a crash log.

btw, it doesn't matter if the RecyclerView is inside a NestedScrollView or not.

what Application are you trying to reproduce the issue. I tried rotating the device for couple of times, Issue not seen. Also provide Device you are using to reproduce the issue

sy...@google.com <sy...@google.com> #3Dec 30, 2015 12:12PM

Any Android 2.3.x, really. The application is a Beta version of an unreleased app.

This issie initially appeared on a Samsung Galaxy Ace with 2.3.3, but after testing it in an Android emulator, it also appeared. The dificulty to reproduce this is because it only seems to happen after a crash of the app (either by OOM or some other bug), and we Android tries to recreate the app, it crashes again with the "ClassNotFoundException when unmarshalling".

Also, we're having another crash similar to this, but in AppBarLayout.Behaviour:

Marked as fixed.

Happens on HoneyComb too.

Another stacktrace, in case it could bring some more info:

This issue could not be reproduced in Marshmallow builds. At this point, our eng teams are not prioritizing changes on earlier releases. Please do let us know if you encounter this issue on 6.0+.

um...@gmail.com <um...@gmail.com> #11Apr 19, 2017 05:44AM

This makes me sad. Because we still have about 10% of our user base that can be affected by this.

Are you aware of any work arounds for this issue?

We considered explicitly setting the class loader during the saving of the state in hopes that might fix it. But, we're not sure of any additional ramifications that might have on saving state.

And, it's not specific to just Android 2, though, this is mostly the case.

97% Android 2
1% Android 4
1% Android 3
1% Other

Any advice would be greatly appreciated.
