[Bug] Unity3D 6.2 can not build with Firebase SDk 13.5 for Meta app

[dorcatty]

Description

hello

these days, i am going to build an Meta App with Firebase Firestorage sdk enabled.
With Unity6.2, we build an app with Meta Core. Interaction SDK v81, build standalone meta app works well without importing firebase SDK,

Once we imported firebase SDK v13.5, we got many errors:
But my script works well via Unity Editor, no issue (no issue of configration). only build for Android has this issue:

Could not find manifest/application tag in android manifest.
UnityEngine.Debug:LogError (object)

and another error:

i am sure that in my Android Manifest, i have these lines:

application field is given in my case.

could anyone help for this issue ? many thanks

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hi @dorcatty, thanks for reaching out. I tried setting up a sample app and following along with the steps you shared, but I didn't encounter any issues with building an Android app. What I did was I used our quickstart app for Firestore as a base, then added these SDKs in order:

• Meta XR Core SDK
• Meta XR Interaction SDK
• Firebase Firestore SDK

After that, I initialized the Firestore SDK and tried running my sample in Unity's Playmode then I built an APK file, but I couldn't reproduce the error you encountered in either scenarios. Though I would like to note that I skipped adding WebRTC for Unity. If I'm missing any other step(s) here or if there's something else I should try, please let me know.

Based on the logs you shared, it looks like the issue may be related to your project's gradle files. I'm thinking they aren't being resolved properly during the build process for your app, or there might be a conflict when the dependencies are being resolved. To give us a better idea of what could be causing the error, could you answer the following:

• Is the EDM4U/Jar Resolver enabled?
• Could you try using the "Force Resolve" function of the EDM4U before building?
  • You can do this via "Assets>External Dependency Manager>Android Resolver>Force Resolve"
• Is the "Custom Main Gradle Template" option enabled in your Player Settings?
  • You may locate this in: Project Settings>Player>Publishing Settings>"Custom Main Gradle Template"
• Have you tried running the command '--warning-mode all'? It might provide us with more insights into the error.
• Lastly, could you also try testing with our Firestore quickstart app then see if you're also getting an error there?

Dear @niccolo-hare , thanks for answering me so quickly.
What i did is very simple: (by the way, i have MacOS M4, using Unity6.2 silicon version, that might the issue ? )

• create a new Unity6.2, URP project,
• enable XR plus-in Management and enable OpenXR,
• change android API level to 34,
• add Meta XR Core SDK, Meta XR Interaction SDK,
• create and register new created Unity App ID with Firebase database via Firebase console, download 'google-services.json' in place it in Unity Assets folder,
• import Firebase Firesotre SDK, v13.5.0 into Unity Editor,
• Open a simple example of Meta Interaction SDK, just 'RayExamples.unity' and try to build, then i have this error

Could not find manifest/application tag in android manifest. UnityEngine.Debug:LogError (object) Meta.XR.Samples.Editor.UpdateManifestWithCodeSample:UpdateManifest (string,System.Collections.Generic.Dictionary2<string, System.Collections.Generic.HashSet1<string>>) (at ./Library/PackageCache/com.meta.xr.sdk.core@d6da9ab40659/Scripts/Editor/Util/SampleMetadata/UpdateManifestWithCodeSample.cs:85) Meta.XR.Samples.Editor.UpdateManifestWithCodeSample:OnPostGenerateGradleAndroidProject (string) (at ./Library/PackageCache/com.meta.xr.sdk.core@d6da9ab40659/Scripts/Editor/Util/SampleMetadata/UpdateManifestWithCodeSample.cs:50) UnityEditor.EditorApplication:Internal_CallDelayFunctions () (at /Users/bokken/build/output/unity/unity/Editor/Mono/EditorApplication.cs:399)

however, i double checked, in my Android manifest, i have application tag for sure

i also tried with Force Resolve, and Custom Main Gradle Template enabled, please double check in my screenshot.

I didn't try with quickstart app, only simple scene from Unity,then i got some error of build.

I am pretty sure that without import Firebase SDK, i can successfully build simple Meta sample project and run on Quest goggle.

importing Firebase SDK introduced some configruation error here in my environment.

do you also have Silicon version of Unity Editor ? sometime, this might be the issue ?

[niccolo-hare]

Hi @dorcatty, thanks for sharing these details. I couldn't find the "RayExamples.unity" sample that you mentioned, so I used this sample from the Unity Asset store as a base for my testing.

After following along the steps you shared, I was able to build an Android app without issue. I also tried this with an empty project and our quickstart sample just to confirm, but I didn't encounter any errors while building.

To answer your question, I also used the Silicon version of the Unity editor (v6000.2.12f1), but on an M1 machine. Though, I'm thinking the error might be leaning more towards dependencies and how they're resolved by Unity (or possibly due to some missing configuration), rather than the Unity editor version. Could you try checking your Meta project settings and see if there's any required fixes that need to be addressed?

For reference, you can check this via the menu: Meta>Tools>Project Setup Tool>Android tab.

Same issue found here. For some reason this script UpdateManifestWithCodeSample is checking all the Manifests of the project and the Firebase SDK includes some files that don´t have the application tag.

Maybe we can try to delete UndateManifestWithCodeSample.cs ....
