unity crash with onDetachedFromWindow

[sewonist]

Hi

First of all, thank you for great work. I've success build React, Unity and Expo with this source in debug and release environment. I should change some code for EAS build.

Unfortunately, I meet other problem. I used Material Top Tab Navigator. When I slide view, It was occurred crash in Unity. You can see that below code. I tested with ReactNativeUnity.addUnityViewToBackground() and without it. This error was occurred both case. I'm not sure why.

If you have any idea, please let me know.

Thanks.

(Tree view is playing Unity side. Other are React components.)

Hi! Similar problems are associated with the assembly of the Unity project and its settings. Try setting this checkbox

[sewonist]

Yeah~~ It's solved!! Thanks again~!!!

I just have other question. Why need ReactNativeUnity.addUnityViewToBackground();? In my case, onDetachedFromWindow was call after slide on Tab Navigator. I will remove in my code. Is it ok?

[azesmway]

you can of course try to remove it, but in this case the unit will not correctly stop when the component closes and may lead to application errors. on my project without this function nothing works

I am having the same error as here mentioned in the mentioned issue above this comment - what auto graphics APIs do you have when the tickbox is unchecked and how is this related to the crash?
