I want to close unity app/player when user press the back button to go to home page of react app. The problem is, unity player keeps running in background. I want to permanently close/kill it when user using react part of my app

Hi Guys,
i tried the forlder example but with npm i and with tar -xf android.tgz
i have this error:
tar: Error opening archive: Unrecognized archive format

any idea?

OS: windows node 18.6

Error occurred when I changed unity iOS settings Target SDK from simulator to device

When running Unity as a standalone application, I observe a memory usage of approximately 300 MB. Similarly, when running React Native as a standalone application, the memory usage is around 200 MB. However, when I integrate the two platforms to create a unified application, the memory usage ~ 1 GB.

I am eager to optimize the memory usage in order to achieve better performance. Could you kindly share some insights and recommendations on how to address this issue? I would greatly appreciate any guidance you can provide to help me optimize the memory usage in the integrated application.

vs ViewProperties dose not work in React Native 0.70

There are 2 parts in my app, the first one is built with React Native (for forms, settings, reports,...) and the second one is built with Unity (for games). Users can switch between the 2 parts when using the app. It works fine on iOS but not on Android.

The Android app crashed when going from React Native to Unity the second time, the first time has no problem.

Steps to reproduce:

1. RN to Unity -> ok
2. Unity to RN -> ok
3. RN to Unity again -> crashed

Please help me to find the root cause to fix it.

Thanks.

I am attempting to run the example project for iOS, but am blocked on Step 3. Add Unity-iPhone.xcodeproj to your workspace

Where does this file come from? I don't see it in the example folder of the repo, is it generated? If so, where and how?

After I installed react-native-unity2 with yarn, I executed pod install, but I have not yet imported the Unity-Phone project in Xcode. After running react-native run ios, this error will be thrown in the terminal.

I'm not sure if the problem is caused by the fact that I'm using a virtual machine.

I have encountered a problem and I don't know how to solve it. I am not an Android developer

Your hardware does not support this application

Press OK to quit.

After the integration of unity exports/project in the React Native project, when we generate the apk using assembleRelease/assembleDeploy, it results in generation of 2 different APKs

1. react native unity integrated apk
2. APK which consists of only the unity project

Could you please suggest a solution to get rid of 2 APKs
How do we alter the configuration of the react-native-unity-2 package to cancel out of the generation of unity project APK

npm seems unable to download from this link during the npm install command npm install react-native-unity2

https://nexus.fuse.ninja/repository/npm-registry/typescript/-/typescript-4.6.4.tgz

I tried the link in my browser and it won't load there either, I'm just using a home network - no fancy proxy or VPN or anything of the like and I do all development on this home network.

Is there a ways to have these files stored somewhere other than a private website in case the worst should happen and the site went down as people wouldn't be able to use this react native implementation either.
