Flutter app crashes on Android (0.14.0) - Too many open files

[denfrancis]

Description

My flutter app crashes on Android devices after remaining idle for some time. This happens when I use Factory.rive riveFactor instead of Factory.flutter. I use the feathering features on Rive and it is disabled when I use Factory.flutter.

Steps To Reproduce

Steps to reproduce the behavior:

1. Run the app on Android
2. Load a rive file that has feathering enabled
3. Wait a few seconds
4. App will freeze and will be unusuable

Expected behavior

• It should not be crashing. The exact file and code works fine on iOS

Device & Versions (please complete the following information)

• Device: Google Pixel 9a
• OS: Android 16
• Flutter Version:

Flutter 3.29.3 • channel [user-branch] • unknown source

Engine • revision cf56914b32

• Rive SDK version: rive: ^0.14.0-dev.6

Additional context

This only happens on Android. It works fine on iOS.

[fufylev]

This happens when I use Factory.rive

Same issue

[andrewpmoore]

I also get a very similar crash, but before that my logs get spammed with

W/ImageReader_JNI( 7625): Unable to acquire a buffer item, very likely client tried to acquire more than maxImages buffers.

I have a list of rive widgets on the screen and it happens nearly straight away. After a while it just crashes. If I change the factory to Rive.flutter, than it works.

I'm using 0.14.0-dev.8

[lawinski]

I have exactly the same issue. It happens only on Android and freezes the whole app after a few minutes. At the same time, I have 5 Rive files rendered on the screen.

Testing device: Google Pixel 4 (Android 13)
Rive Editor: Early Access 0.8.3562
rive_native: ^0.0.11
rive: ^0.14.0-dev.8

I am seeing spam of below line when Rive animation goes out of the viewport. Doesn't crash though.

Unable to acquire a buffer item, very likely client tried to acquire more than maxImages buffers

[HayesGordon]

I need to look into Unable to acquire a buffer item, very likely client tried to acquire more than maxImages buffers

But the latest release fixed a graphics memory issue, which very likely should solve the above crashes/issues.

Could you try 0.14.0-dev.11 and let us know.

If the latest does not solve the issue could you please provide a small sample project with steps to reproduce the issue.

@HayesGordon , the issue seems to be happening. Here is minimal sample code using 0.14.0-dev.11 version of Rive. Let me know if you need the animation file as well or if this is enough to reproduce. When you scroll just enough that Rive animation goes out of the visible area, the logs flood with:

@nikorehnback just to confirm, is this a reproduction of the warning log you're seeing? Or does this reproduce one of the crashes mentioned above?

@nikorehnback just to confirm, is this a reproduction of the warning log you're seeing? Or does this reproduce one of the crashes mentioned above?

This reproduces the warning. No crash with this one. Also tried to add 10+ RiveWidgets, only more same message to logs, no crash with that either.

[andrewpmoore]

Yes, the same for me (the log spamming) , i have a list of 11 rive animations the play as get this as soon as I scroll the list with them into view, but not spotting any actual crashes
