GoogleMobileAds 9.1.1

MacOS Sonoma 14.6

Xcode 15.4

----

GoogleMobileAds 9.1.0까지는 iOS에서도 정상 빌드가 됐었는데,

GoogleMobileAds 9.1.1로 올려서 빌드해보니 빌드는 잘되지만, 실행하자마자 아래와 같은 로그를 남기면서 Crash가 난다.

로그만 봐서는 MarketplaceKit 관련해서 이슈인 것 같아서 이래저래 찾다보니 아래 참조와 같은 이슈가 올라와 있다.

위의 참조 링크 댓글 중 아래와 같은 글이 있다.

(댓글에 보면 요구조건에 Xcode 15.3이상 이라고 돼 있지만, 지금 나는 Xcode 15.4를 쓰고 있다)

TvaroshFlyboys commented

based on the release log of google mobile ads version 11.6.0, they've added dependency on the MarketplaceKit:

GoogleMobileAds 릴리즈 노트(https://github.com/googleads/googleads-mobile-unity/releases)를 보면 GoogleMobileAds iOS SDK to 11.6.0은 GoogleMobileAds Unity Plugin v9.1.1에 추가 됐다.

MarketplaceKit이 추가된 GoogleMobileAds Unity Plugin v9.1.1(GoogleMobileAds iOS SDK 11.6.0) 부터 iOS 빌드 시 Runtime Crash가 나고 있고,

현재 최신 버전인 GoogleMobileAds Unity Plugin v9.2.0(GoogleMobileAds iOS SDK 11.7.0)도 여전히 Runtime Crash가 나고있다.

혹시나 싶어서 엔진 최신버전인 Unity 6000.0.13f1으로 올려서도 빌드해 봤지만, 여전히 Runtime Crash가 난다.

[결론]

이 문제가 GoogleMobileAds iOS SDK 이슈인지 Xcode 이슈인지는 모르겠지만,

현재로서는 GoogleMobileAds Unity Plugin v9.1.0을 쓰면서 수정 업데이트를 기다려야 될 것 같다.

With recent Unity versions (2020, 2021 and 2022) Flutter Android builds will take a lot longer, because it also has to compile the IL2CPP code from Unity.

From the Readme:

• Android builds takes forever to complete Unity 2022.1.*, remove these lines from unityLibrary/build.gradle filecommandLineArgs.add("--enable-debugger")
  commandLineArgs.add("--profiler-report")
  commandLineArgs.add("--profiler-output-file=" + workingDir + "/build/il2cpp_"+ abi + "_" + configuration + "/il2cpp_conv.traceevents")

Here is some testing to check how to speed things up.

Unity settings

IL2CPP Code Generation

• Build Settings -> IL2CPP Code Generation: select Faster (smaller) builds instead of Faster runtime.
• Or C# EditorUserBuildSettings.il2CppCodeGeneration = UnityEditor.Build.Il2CppCodeGeneration.OptimizeSize;

C++ compiler configuration

• In Player settings -> Other settings -> configuration, select Debug.
• Or C# PlayerSettings.SetIl2CppCompilerConfiguration(BuildTargetGroup.Android, Il2CppCompilerConfiguration.Debug);

Disable script debugging

Don't bother setting this in the Unity settings, it will be overridden by the build script.
Assets/FlutterUnityIntegration/Editor/build.cs
In the function DoBuildAndroid() remove the line enabling script debugging.
playerOptions.options = BuildOptions.AllowDebugging;
This is the same as removing commandLineArgs.add("--enable-debugger") from the build.gradle file after an export.

Measuring results

When you run a Flutter build, there are multiple IL2CPP stages that report their duration, with 2 sections taking far longer than all others.
We can compare these build durations when using different settings in Unity.

Build succeeded with 553 successful nodes and 0 failed ones

Results

The exact durations here aren't important, as this will be different of every computer and project setup.
This is after flutter clean and a fresh Unity export. Any subsequent runs will be faster because of caching.

Flutter build apk, with an export from Unity 2021.3.5f1 in android/unityLibrary on Windows 10.

Settingarmv7 durationarm64 duration

Conclusion

My advice is to add this to the build script in DoBuildAndroid() for any test or debug builds, remove it for final release builds.

//Assets/FlutterUnityIntegration/Editor/build.cs
bool isReleaseBuild = false;

#if UNITY_2022_1_OR_NEWER
    PlayerSettings.SetIl2CppCompilerConfiguration(BuildTargetGroup.Android, isReleaseBuild ? Il2CppCompilerConfiguration.Release : Il2CppCompilerConfiguration.Debug);
    PlayerSettings.SetIl2CppCodeGeneration(UnityEditor.Build.NamedBuildTarget.Android, UnityEditor.Build.Il2CppCodeGeneration.OptimizeSize);
#elif UNITY_2021_2_OR_NEWER
    PlayerSettings.SetIl2CppCompilerConfiguration(BuildTargetGroup.Android, isReleaseBuild ? Il2CppCompilerConfiguration.Release : Il2CppCompilerConfiguration.Debug);
    EditorUserBuildSettings.il2CppCodeGeneration = UnityEditor.Build.Il2CppCodeGeneration.OptimizeSize;
#endif

If it doesn't affect your workflow, disable script debugging.

// playerOptions.options = BuildOptions.AllowDebugging;

And if you are developing on an arm64 device anyway, temporarily remove the armv7 build target from the Unity player settings.

[추가4] 2024-08-06

Play Asset Delivery v1.9.1이 업데이트 돼있어서 적용함.

[추가3] 2024-03-27

Play Asset Delivery v1.9.0(2024-03-27 기준 최신)이 업데이트 됐다.

1.9.0은 최소 Unity 버전이 2017.4로 표기돼있다.(버전별 문제를 해결한건가..?)

[추가2]

AssetDelivery 1.7.0으로 iOS 빌드 하면서 ./GooglePlayPlugins/com.google.play.assetdelivery/Samples 폴더 관련 소스에서 에러가 나서 삭제 함.

[추가]

aab파일 150mb 초과해서 구글스토어 올리려고 알아보고

아래 [링크]의 내용대로 진행해서  Play Asset Delivery v1.8.2(2023-04-25 기준 최신)를 설치해서 빌드해보니,

빌드는 잘 되지만 실행하면 크래시 나면서 앱이 죽는다.

버전 정보를 보면 Play Asset Delivery v1.8.0 이상부터는 Unity 최소 버전이 2023.1.0 (베타)이다.

(1.8.0이상은 2023.1.0 이상이라고 돼있지만 2022.2.18f1에서 정상동작 하는걸 확인했다.)

[참조] https://github.com/google/play-unity-plugins/issues/187

크래시 내용을 찾아보니 위[참조]와 같은 내용이 있다.

Firebase와 PAD(Play Asset Delevery)와 호환성 문제가 있는 것 같다.

참조 링크의 내용대로면 현재 Play Asset Delivery v1.8.x 버전은 제대로 안되고, Play Asset Delivery v1.7.0을 사용해서 성공했다고 한다.

[Github:Play Unity Plugins v1.7.0] https://github.com/google/play-unity-plugins/releases/tag/v1.7.0

[Google Play:Play Asset Delivery] https://developers.google.com/unity/archive?hl=ko#play_asset_delivery

위 Play Asset Delivery 링크에서 1.7.0버전 UnityPackage를 다운로드해서 Import하고,

정상 빌드 되는 것을 확인했다.

[결론]

Unity 2021 이하는 Play Asset Delivery 1.7.0을 사용하고,

Unity 2022 이상은 Play Asset Delivery 1.8.2(2023-05-12 기준 최신)을 사용하자.

(Unity 2021에서도 gradle 4.2.0을 적용하면 Play Asset Delivery 1.8.2 이상을 사용할 수 있다.

  2024-03-27 기준 1.9.0이 나와있으니 1.9.0을 사용하자.)

그래도 다시 이리저리 검색해보다보니 해결했다는 글이 아래와 같이 있다.

UnayOzan commented on Feb 5
Fixed this error with changing the version in "GoogleSignIn.podspec.json" file.

Firebase/Auth (= 10.4.0) was resolved to 10.4.0, which depends on
FirebaseAuth (~> 10.4.0) was resolved to 10.4.0, which depends on
GTMSessionFetcher/Core (< 4.0, >= 2.1)

GoogleSignIn (~> **5.0.2**) was resolved to **5.0.2**, which depends on
  GTMSessionFetcher/Core (~> **1.1**)
I found the file in {user}.cocoapods/repos/cocoapods/Specs and then just search for "GoogleSignIn.podspec.json".
Find the folder with the same version with the error, in my case 5.0.2.
And then change its dependencies with the version 7.0.0 or something that works with the other packages.
In my project the solution was this;

 "dependencies": {
    "AppAuth": [
      "~> 1.5"
    ],
    "GTMAppAuth": [
      ">= 1.3",
      "< 3.0"
    ],
    "GTMSessionFetcher/Core": [
      ">= 1.1",
      "< 4.0"
    ]
After that I exited Xcode, deintagrated pods, cleaned cache and installed it again.
Everything works fine now.

글을 보면 아래와 같은 내용이 있다.

In my project the solution was this;

에러도 나와 거의 같아서 확인해보니 GoogleSignIn 버전이 현재 6.0.2여서 GTMSessionFetcher/Core (~> 1.1)를 지원하는데,

설치한 FirebaseAuth 10.6.0은 GTMSessionFetcher/Core (< 4.0, >= 2.1)을 사용하고 있어서

GTMSessionFetcher/Core 버전이 서로 호환이 안되는 것 같다.

위 링크의 내용대로

GoogleSignIn 버전을 7.0.0(2023-03-27 기준 최신) 버전으로 변경하고 빌드를 다시해보니 깔끔하게 빌드가 잘 된다.

[추가]

빌드는 잘 되는데 회사 플랫폼에서 사용하는 GoogleSignIn이 6.0.2여서 7.0.0으로 올리면서 API 호환이 안돼서 로그인 시도할 때 Crash가 나면서 앱이 강제종료 된다.

6.2.4
  2.x 버전을 허용하도록 GTMSessionFetcher 종속 항목을 업데이트했습니다. (#207)

GoogleSignIn에서 해당 빌드 오류 이슈를 해결한 버전은 6.2.4여서 6.2.4로 버전을 내렸다.

나처럼 다른 이슈로 7.0.0으로 못올리는 사람은 6.2.4로 한 번 시도해 보면 좋을 것 같다.

Unity 2021.3.11f1

I2 Localization(app_name 로컬라이징 용도)

I2 Localization 에셋으로 app_name Localization을 하고 있었는데,

Unity 2021.3.11f1으로 업데이트 한 후에 Android에서 로컬라이징이 되지 않고 기본 설정된 App Name만 나오는 문제가 생겼다.

(대충 검색해보니 Unity 2021.3부터 나오는 이슈 같다)

그래서 생성된 res 폴더를 ../Assets/Plugins/Android/ 하위에 직접 넣고 빌드해보니 아래와 같은 에러가 나온다.

Exception: OBSOLETE - Providing Android resources in Assets/Plugins/Android/res was removed, please move your resources to an AAR or an Android Library. See "AAR plug-ins and Android Libraries" section of the Manual for more details.

app_name 로컬라이징에 사용되던 /res/ 폴더 하위에 넣는 방식을 Unity 2021.3 이후에는 더이상 지원하지 않나보다.

그래서 검색해보니 아래 링크에 해결방법이 적혀있다.

[링크] https://develop.hateblo.jp/entry/android-res-error

해결방법은 링크의 res.androidlib 폴더를 만드는 방법을 참조하면 된다.

링크의 xml 파일등이 띄어쓰기등이 좀 문제 있어서 겸사겸사 간단히 요약해서 적어 둠.

  [해결방법]

1. ../Assets/Plugins/Android/ 하위에 res.androidlib 폴더 생성

2. res.androidlib 폴더에 아래 파일을 다운받아서 추가하거나 AndroidManifest.xml 파일 직접 생성해서 입력

[참조] AndroidManifest.xml 파일 내용

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="custom.android.res" android:versionCode="1" android:versionName="1.0">
</manifest>

2. res.androidlib 폴더에 아래 파일을 다운받아서 추가하거나 project.properties 파일 직접 생성해서 입력

[참조] project.properties 파일 내용

target=android-9
android.library=true

3. 기존에 있던 res 폴더(하위에 values/values-en/values-ko 등 포함)를 res.androidlib 폴더로 이동

4. 위의 순서 진행하면 아래와 같이 된다.

5. 이제 빌드 하면.. 된다!!
