the unity 2017 show lot of error needs to be fix, and when I press the run button

It show me the message of "all compiler error have to be fixed before you can enter playmode"

And my unity version is 2017.4.14f1 Personal

Hi, thanks for the plugin first of all,
but i'm having a problem here while trying to export my unity project to android, even tho, i followed the tutorial as it is, fresh project nothing yet added but cube.

says:

I also tried to manage to solve the problem by creating the folder required manually. But after that, i face another error regarding build.gradle

I hope this error get solution, in advance.
Thanks

5. npm run watch
   

6. open in xcode and build failure
   UnityInitStartupTime(); //Use of undeclared identifier 'UnityInitStartupTime'

7. npm run android or npm run ios

how to fix UnityInitStartupTime() not found ?

Using XCode Version 10.2.1, branch master, Unity 2018.2.11f1.

RN 0.57 used in the demo has an issue with this version of XCode, as indicated here: facebook/react-native#21071.

Order of operations:
a. npm install
b. installed patch-package

When I run your demo on Emulator or Device I get the above error, please help me to solve it, thanks

When I build your example project I get this error and as far as I find out it's because I haven't added the project's certificate to the cacerts of JDK file as shown below but Can you show me how to generate the peoject certificate file is that Okay?

Hi,

When building this project on the master it succeed however when I press the button to "Toggle Unity" It crashes and it showed me this error.

When building the error "/Users/xzper/workspace/web/npm-package/react-native/unity/demo/ios/UnityExport/Data" occurs from the master.

This is probably a wrong link because I am not xzper. However can't find the file that is linking to it.
Does somebody have the solution

This may be unrelated but I have been trying to get a transparent background for Unity so you can see react-native components underneath the react-native-unity-view for Android, I have got it working for iOS.

For Android I have tried:
Preserve frame buffer alpha = true,
Set Camera to solid color RGBA { 0, 0, 0, 0 },
Using OpenGLES3

My problem is that the background is simply rendered as black, however if I ran the Unity Export by itself as an apk then it is clearly transparent. I am just wondering if there is something that react-native-unity-view does to the Unity Player that would remove this transparency.

Fresh React-Native-Unity-Demo project, unity version 2018.3.6f1

Looks like the path to the build is wrong as it finds it if I change it to "Unity/UnitySharedDecls.h", but changing it gives me 200 errors in xcode.

Hi,
first I want to say thank you for this react-native plugin !
It could be a best plugin to combine react-native & Unity

I have a problem with the installation of your demo.
First I had this issue : #2
It solve my first problem but a second has arrived.

Undefined symbols for architecture arm64: "_onUnityMessage", referenced from:

I'm on Unity 2017.2.0f3 & XCode 9.3

Have you an idea ?
Thanks a lot !

Hi all,
I am trying to import a Unity project in my react native application. I tried following the general instructions and it resulted in an error. Now i cloned this example file, followed the intructions and the same error appears. It is this one:

Could not find method bundle() for arguments [build_99q93k10d6vp7m7tejceyj4qi$_run_closure3$_closure12@6612fee7] on object of type com.android.build.gradle.LibraryExtension.

Any idea how I can solve this? in both cases i followed step by step the instructions that were given and in both cases this is the error i have

Thank you, silvia

Does this demo work with unity vuforia, or arkit?

I am just trying to get the demo project to build by following the instructions but I only get as far as here. I have seen reference to this error on the npm package repo but I don't see a clear fix.

Environment

  "dependencies": {
    "react": "16.5.0",
    "react-native": "0.57.0",
    "react-native-unity-view": "^1.3.0"

    "react-test-renderer": "16.2.0",
    "typescript": "^2.7.1"
  },

There's no way to dismiss the UnityView from JS.

I don't found any proper solution anywhere. attached the screenshot please help.

I guess there is something wrong with the message bus. I tapped everywhere but the counter does not increase. Can anyone verify that the message bus is working as expected?

I am try to setup this demo project:

My development environment is as follows:

Unity: 2018.3.11f1
Xcode: 10.2
Android Studio: 3.0

I have project under unity/Cube/Assets/test.unity inside Unity. And the next step was to try doing Build > Export Android / Export iOS.

Export Android build fine, but when I do npm run android after "npm install" it says

* Where:
Build file '/Users/saudahmed/Downloads/react-native-unity-demo-master/android/UnityExport/build.gradle' line: 78

* What went wrong:

> Could not find method bundle() for arguments [build_cxleajmcepp8gnsdjtwlgsv2v$_run_closure3$_closure12@4ef76084] on object of type com.android.build.gradle.LibraryExtension.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

When i do npm run ios it gives

I swapped out the cube unity project with my own, followed the instructions and built for IOS. But when running from XCode on a iphone I get this issue. Any troubleshooting ideas?

Hi,
I am trying to build this demo on my mac which has unity 2018.2.11f1 and xcode version 10.0. I am getting the following error:

error: Build input file cannot be found: '/Users/myUser/Desktop/react-native-unity-demo-master/ios/UnityExport/Classes/Native/Bulk_UnityEngine.UnityConnectModule_0.cpp'

Any ideas?

I just tried this demo. I am using Unity 2017.2.0f3 and Xcode 9.3.

1. i just simply copy the Build.cs script and encounter this problem, any solution? i got this error:
   Assets/Scripts/Editor/Build.cs.cs(9,39): error CS0234: The type or namespace name Reporting' does not exist in the namespace UnityEditor.Build'. Are you missing an assembly reference?

2. the build button require me to change the 'Package Name', what is the package name should i give? thank you

i use Unity 2017.4.3f1

I ran the following commands:
git clone https://github.com/f111fei/react-native-unity-demo
cd react-native-unity-demo
npm install
react-native upgrade
react-native link react-native-unity-view
npm run watch
npm run ios

And when the app comes up on the emulator I am seeing:

Invariant Violation: Native component for "UnityView" does not exist

I feel like I must be missing a step. Is it clear what I'm doing wrong?

For more information:
npm = 6.0.0
node = v8.11.1
unity = 2017.4

After run "npm run watch" command as per mentioned steps then shows below error in terminal.

Ok, so i had this two issues.

Both fixed in Build.cs . In comments after // ... it is version which was before changes!

public static void DoBuildAndroid()

string buildPath = Path.Combine(apkPath); // -not working version Path.Combine(apkPath, Application.productName);
string exportPath = Path.GetFullPath(Path.Combine(ProjectPath, "../../android/UnityExport"));

    if (Directory.Exists(apkPath))
        Directory.Delete(apkPath, true);

    if (Directory.Exists(exportPath))
        Directory.Delete(exportPath, true);

    EditorUserBuildSettings.androidBuildSystem = AndroidBuildSystem.Gradle;

    var options = BuildOptions.AcceptExternalModificationsToPlayer;
    var report = BuildPipeline.BuildPlayer(
        GetEnabledScenes(),
        apkPath,
        BuildTarget.Android,
        options
    );

    if (report.summary.result != BuildResult.Succeeded)
        throw new Exception("Build failed");

    Copy(buildPath, exportPath);

    // Modify build.gradle
	var build_file = Path.Combine(exportPath, "build.gradle");
	var build_text = File.ReadAllText(build_file);
	build_text = build_text.Replace("com.android.application", "com.android.library");
    build_text = build_text.Replace("implementation fileTree(dir: 'libs', include: ['*.jar'])", "api fileTree(include: ['*.jar'], dir: 'libs')");
    // build_text = build_text.Replace("implementation(name: 'VuforiaWrapper', ext:'aar')", "api(name: 'VuforiaWrapper', ext: 'aar')");
	build_text = Regex.Replace(build_text, @"\n.*applicationId '.+'.*\n", "\n");
	File.WriteAllText(build_file, build_text);

    // Modify AndroidManifest.xml
    var manifest_file = Path.Combine(exportPath, "unityLibrary/src/main/AndroidManifest.xml"); //   -not working version, missed 'unityLibrary/' + src/main/AndroidManifest.xml");
    var manifest_text = File.ReadAllText(manifest_file);

    manifest_text = regex.Replace(manifest_text, "");
    File.WriteAllText(manifest_file, manifest_text);
}

Cheers!

hi! thanks for this package!

I'm getting this error in Unity when running Build -> Export iOS. I'm not familiar with Unity, any ideas what might be going on here?

To reproduce:

1. Open unity/Cube/Assets/test.unity (using Unity v. 2017.2.0f3)

2. Click Build => Export IOS

Assets/Scripts/UnityMessageManager.cs(143,10): error CS0111: A member 
'UnityMessageManager.onUnityMessage(string)' is already defined. Rename this member or use 
different parameter types

Error building Player because scripts had compiler errors

Exception: Build failed: 2 errors
Build.DoBuildIOS () (at Assets/Scripts/Editor/Build.cs:78)

On a Samsung Galaxy S7 Edge I'm receiving the following error:

03-23 10:30:12.444 20044-20044/? E/art: Failed to register native method com.unity3d.player.UnityPlayer.nativeIsAutorotationOn()Z in /data/app/com.rnunitydemo-1/split_lib_dependencies_apk.apk:classes33.dex
03-23 10:30:12.445 20044-20044/? E/art: ----- class 'Lcom/unity3d/player/UnityPlayer;' cl=0x12caba90 -----

Will let you know if I figure anything out but perhaps you have some better intution about this?

(I'm using Unity 2017.3.1p2 to compile, fyi)

after using npm run android I get the following error:

FAILURE: Build failed with an exception.

* Where:
Build file '/home/jose/tmp/react-native-unity-demo/android/app/build.gradle' line: 129

* What went wrong:
A problem occurred evaluating project ':app'.

I am able to run the demo, that is working fine on Android, but on iOS the message isn't received from Unity. Am I missing something?

I also would like to have the Unity view starting already enabled instead of clicking on "Toggle Unity", but just changing the state.renderUnity to true doesn't work.

Any idea?
My Unity version is 2017.4.0f1 and React Native is 0.53.0.

Thanks!

Hello!

First I would like to thanks you for this effort!

• Using code from master (24/06/2018)
• Unity version 2018.1.3f1
• Xcode 9.4.1

I have been trying to run the demo on iOS but haven't been able to do it. Initially I got this error:

Then to fix it I duplicated the rndemo schema and named it rnunitydemo. After that I get the following error:

Hey - very awesome project excited to try this out.
Unfortunately the instructions you have in the read me are not working for me...

While everything works fine with React Native below any version under 0.60 (and already reported at As already reported in f111fei/react-native-unity-view#142), on Android the application will crash upon activating the UnityView with RN > 0.60.

The final error happens because of a "libmain.so" could not be loaded:

E Unity   : Failed to load 'libmain.so', the application will terminate.
D AndroidRuntime: Shutting down VM
E AndroidRuntime: FATAL EXCEPTION: main
E AndroidRuntime: Process: com.rnunitydemo, PID: 16887
E AndroidRuntime: java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.rnunitydemo-bKGyotdcwjVnBxuR9zLE4Q==/base.apk"],nativeLibraryDirectories=[/data/app/com.rnunitydemo-bKGyotdcwjVnBxuR9zLE4Q==/lib/arm64, /data/app/com.rnunitydemo-bKGyotdcwjVnBxuR9zLE4Q==/base.apk!/lib/arm64-v8a, /system/lib64, /product/lib64]]] couldn't find "libmain.so"

According to a crash-report in the official Unity-Forum, we took care to use the same settings in both build.gradle for ndk-abiFilter:

android {
    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 28
        ndk {
            abiFilters 'armeabi-v7a', 'x86'
        }
        multiDexEnabled true
        versionCode 1
        versionName '0.1'
    }
}

but it won't fix the issue. There is a big chance that the issues f111fei/react-native-unity-view#120 and f111fei/react-native-unity-view#129 might be related to this one.

Anybody found a proper solution for this?
