created issue #1

Jul 13, 2020 09:29PM

Artifact used (ex. androidx.appcompat:appcompat:1.0.0-alpha1): androidx.recyclerview:recyclerview-selection:1.1.0-rc01
Version used: 1.1.0-rc01
Theme used: Theme.AppCompat.Light.DarkActionBar
Devices/Android versions reproduced on: Motorola Moto G6, Android 9

When the item views of a RecyclerView have OnClickListeners attached, the behaviour of firing onClick events during selection is quite unpredictable. As soon as at least one item was selected, classic ListView did no longer fire any click events for individual list items until all items were unselected.
Current recyclerview-selection exhibits two behaviours I would consider a bug, but maybe I'm using the API in a wrong way:
1. When long-clicking an item to enable multi-item selection, the item is marked as selected/activated as expected. But as soon as you release the finger, an onClick event will be triggered, despite the fact that RecyclerView is currently in selection mode. This behaviour is new since 1.1.0-rc01 and was not present in 1.0.0.
2. After enabling selection mode by long-clicking an item, you can select/activate other items by simply clicking on them. This works fine as long as you click through the items slowly. Then one by one gets selected and no onClick events get fired. But when you click a bit faster, every second item is not selected, but instead clicked (triggering onClick event). This problem existed in 1.0.0 and is still present in 1.1.0-rc01.

The following log shows a sequence of onItemStateChanged and onClick events triggered by long-clicking item 0 to enable selection, then clicking items 1, 2 and 3 quickly.
Expected result: Item 0 is selected, then items 1, 2 and 3 are selected, no onClicks get triggered.
Result on my device: Item 0 is selected, then onClick is triggered for item 0. Items 1 and 3 are selected and item 2 fires an onClick event in between.

click item 0 and hold button:
2020-07-13 21:55:01.402 15005-15005/com.example.recyclerviewdemo E/onItemStateChanged: 0: true
item 0 is selected, now release finger:
2020-07-13 21:55:02.306 15005-15005/com.example.recyclerviewdemo E/onClick: item 0
now click (and release) items 1, 2 and 3 quickly:
2020-07-13 21:55:06.850 15005-15005/com.example.recyclerviewdemo E/onItemStateChanged: 1: true
2020-07-13 21:55:07.038 15005-15005/com.example.recyclerviewdemo E/onClick: item 2
2020-07-13 21:55:07.236 15005-15005/com.example.recyclerviewdemo E/onItemStateChanged: 3: true

Attached is an Android Studio project to reproduce the behaviour.
Item IDs == item positions for brevity, the library behaves the same way in a more complex project with "real" item IDs and a custom key provider.

A couple of questions:

1. Have you saw crash in real device or only in simulators?
2. Do you use dynamic feature for language ID?

Tested on Android 12 Emulator with custom executor, but cannot repro this issue.

ki...@gmail.com <ki...@gmail.com> #4Jul 27, 2020 07:52PM

Second crash in the description is from a real device. Experienced it myself on two different Xiaomi phones, plus lots of crashes from users in the Google Play console.
Dynamic features are not used in the application.

As a wild guess, I have downgraded build tools from 31.0.0 to 30.0.3, compileSdk from 31 to 30, and moved all work with Language ID to the service in a separate process (just to be sure that crash can kill secondary process instead of main). This combination is in beta for 2 days by now and I don't see any SIGSEGV crashes.

sm...@google.com <sm...@google.com> #5Jul 28, 2020 03:44PM

Hmm, I feel the crash might be something related to separate/secondary process.

I also changed compileSdk and targetSDK to 31 but still cannot repro this issue.

ki...@gmail.com <ki...@gmail.com> #6Jul 28, 2020 04:26PM

On the contrary, there was no separate process before, when crashes started.

In the new build (with the aforementioned changes) I can see SIGSEGV crash, but only one instead of dozens and it has a bit different backtrace:

signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)

FYI, ML Kit launched a new language ID SDK in the latest release, which uses a new language ID model. https://developers.google.com/ml-kit/release-notes#august_11_2021

Could you try the new SDK version(17.0.0) to check if you can still repro this native crash? Thanks!

sm...@google.com <sm...@google.com> #8Aug 14, 2020 06:14PM

Thank you, I'll try it and check.

Hello. I have similar experience.

I'm using mlkit-language 16.1.1
I didnot meet this error until using AGP 4.2
I can get this error since using AGP 7.0
This error raised on Release build only(minimized by R8)
This error raised without obfuscation.

Also I found there is a post which presents same issue on stackoverflow.

Could you also check if this is reproducible on 17.0.0 or 17.0.1? If yes, could you attach the full log that I can take a look? Thanks!

Hi,

Looks like we figured out the root cause in b/203573699

For temporary workarounds for the existing SDKs, you need to add this rule

-keep class com.google.mlkit.nl.languageid.internal.LanguageIdentificationJni { *; }

for language-id 16.1.1, and add this rule

-keep class com.google.mlkit.nl.languageid.internal.ThickLanguageIdentifier { *; }

for version language-id 17.0.0+ for the newer model.

We'll fix this issue in the upcoming release so that you'll not need these workarounds in the future release.

Thanks a lot for reporting this issue!

ap...@google.com <ap...@google.com> #16Aug 19, 2020 01:54AM

Added workarounds in Known issues section in public docs.

Marked as fixed.

I believe all primary issues raised here have been addressed. Fixes will appear in the upcoming rc02 release.
During testing, I did discover a few corner cases I believe are not regressions but relate to touch handling. I'll document those is separate bugs.

I have no idea what this means.
Did you drop API 25 support in rc02?

sm...@google.com <sm...@google.com> #23Sep 2, 2020 10:20PM

Wow. That's a mighty stack trace! (Not making fun, just....wow!)

The release doesn't contain any changes to target APIs or adopt any new SDK features. The AndroidX toolchain is quite rigorous in guarding against accident adoption of features. The library uses the AndroidX defaults: minSdk of 14 and source compatibility with Java 8.

I think this is the first release that actually employs a Java 8 feature, though. A function reference.

SelectionTracker:
> EventBridge.install(mAdapter, tracker, mKeyProvider, mRecyclerView::post);

So I'd check your project settings to see if you've enabled support for 1.8 language features.

Lemme know how it works out for you.

ki...@gmail.com <ki...@gmail.com> #24Sep 3, 2020 06:14AM

"the AndroidX defaults: minSdk of 14 and source compatibility with Java 8"

Is that documented anywhere? The AndroidX introductory pages and the migration guide didn't note Java 8 source compatibility as a requirement.
I now added:

compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}

It compiles fine and part 2 of this bug (fast clicking multiple items in a row) seems fixed. However, onClick() is still triggered after enabling selection with a long click. I can also confirm the bugs you disovered in

comment #9

.
Thanks for investigating and fixing the bugs on "your" side of the library.

PS: I don't get the point of burying AndroidX bugs in Google's private trackers and linking to them here. The public bug tracker is becoming more and more useless, sorry.

sm...@google.com <sm...@google.com> #25Sep 3, 2020 04:20PM

Using FancySelectionDemoActivity I'm not able to reproduce the issue where child view OnClickListener is called after long press that initiates selection. I can only repro the case where OnClickListener is called after long press on an existing selection (

https://b.corp.google.com/issues/166836317).

*Question*
This is repro-able in the original demo app you uploaded?

*Ask*
Would you mind trying to repro the problem with FancySelectionDemoActivity (from the AndroidX samples folder)? Each child view has an OnClickListener that turns the background dark. So it's jarringly obvious when OnClick is handled.

I'd like to figure this one out, because OnClick firing on initial selection would be a stable release blocker for me, but firing on an existing selection not so, since that would seem an uncommon action by users.

As to public vs private bugs. I'll make an effort to prioritize public issues over private issues. FWIW, I'm a part time contributor to AndroidX. I've been tracking my work using internal bugs, because
1) that's what is "normal" for me, and
2) I track prospective work ideas there that I don't want made public (because people will look at them as promises, which they aren't).

Does your comment on public vs private apply to other components or just RecyclerView-Selection? I'm happy to relay feedback if it applies to others.

ki...@gmail.com <ki...@gmail.com> #26Sep 3, 2020 06:19PM

Yes, the one I uploaded shows the error.
Can you attach an Android Studio project of FancySelectionDemoActivity?

sm...@google.com <sm...@google.com> #27Sep 3, 2020 06:43PM

I'll try out your demo app.

FancySelectionDemoActivity is accesible via SupportV7Demos

https://cs.android.com/androidx/platform/frameworks/support/+/androidx-master-dev:samples/Support7Demos/

You can launch it directly from android studio, or it is accessible from the API Demo app under RecyclerView > Selection > "Gesture and Pointer (for Chromebooks!)"

ki...@gmail.com <ki...@gmail.com> #28Sep 4, 2020 06:42AM

https://cs.android.com/androidx/platform/frameworks/support/+/androidx-master-dev:samples/Support7Demos/

I'm sorry but I really don't understand that site.
Is there any possibility to download the whole demo and not just single files?

sm...@google.com <sm...@google.com> #29Sep 4, 2020 05:13PM

Okay. Repro'd in both your demo app and the app from Support7Demos. The trick is to keep your finger very still during the long press. If there is any intermediary movement in GestureDetector's "slop square" the long press will still fire, but the OnClickListener won't.

I guess my hands are shakier than yours :)

I updated

https://b.corp.google.com/issues/166836317 with details and will track resolution there. Will leave this bug closed since it covered multiple issues.

Thanks again for helping out, your feedback is helpful and appreciated!
