Issue setting up BabylonJS on RN

Questions
1

Hey guys, I’m new to the framework and having some issues setting it up on RN(@babylonjs/react-native). The problem seems to be related to a conflict between Babylon and Viro React(https://github.com/ViroCommunity/viro) due to ArCore versions i guess. On a fresh project it works just fine, but Viro React is a must for my project.

Thats the error i’m getting:

[:arcore_client] /project/node_modules/react-viro/android/arcore_client/build/.transforms/8a1c382d15b6830d95b4fffc34498914/jetified-core-1.10.0/AndroidManifest.xml Warning:
Package name ‘com.google.ar.core’ used in: :arcore_client, com.google.ar:core:1.14.0.

See http://g.co/androidstudio/manifest-merger for more information about the manifest merger.

Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0.

Suggestion: add ‘tools:replace=“android:value”’ to element at AndroidManifest.xml:33:9-35:41 to override.

FAILURE: Build failed with an exception.

What went wrong:
Execution failed for task ‘:app:processDebugMainManifest’.
Manifest merger failed with multiple errors, see logs

Adding ‘tools:replace=“android:value”’ doesn’t seem to fix the issue. Is there anything i can do on the babylonjs end to fix it? i don’t need the webxr functionality for now. Thank you!

It looks like a different version of Android SDK between arcore in BabylonNative and viro.
I’ve found some infos here : add 'tools:replace="Android:value"' to <meta-data> element at AndroidManifest - Stack Overflow
note, tools:replace=“android:value value is an expected Android sdk version.
Also, you can try to change the arcore version in BabylonNative
BabylonNative/build.gradle at 9af6fcc36f3ff60ba0feb75957cad7dd112f8ca4 · BabylonJS/BabylonNative · GitHub
With the same version as viro. Other versions that 1.14 have not been tested with BabylonNative.

All the code that uses the ARCore SDK is precompiled, so do we actually even need to reference ARCore in the build.gradle file? @mihuron if you go to the root directory of your React Native app, open node_modules/@babylonjs/react-native/Android/build.gradle and comment out the line that says implementation 'com.google.ar:core:1.14.0' do you get different errors?

Thanks for the help @Cedric and @ryantrem , commenting out implementation 'com.google.ar:core:1.14.0' from Babylon build.gradle as @ryantrem said, fixed the issue, everything working great now.

Thanks!

Ok, great! We should do some more testing and see if this breaks any other scenarios, and if not remove it from the source. @mihuron it would be great if you could log in issue on GitHub! Issues · BabylonJS/BabylonReactNative (github.com)
