Build Failure Due to Duplicate libreactnative.so File in Realm and React-Android

[Jean-Diniz]

How frequently does the bug occur?

Always

Description

When building the app with Gradle, the build process fails due to a duplicate libreactnative.so file. I expected the app to build and install without issues, but instead, the build fails with an error indicating that there are two instances of libreactnative.so, one from the realm library and another from react-android. This conflict prevents the app from installing.

Stacktrace & log output

Execution failed for task ':app:mergeDebugNativeLibs'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.MergeNativeLibsTask$MergeNativeLibsTaskWorkAction 
> 2 files found with path 'lib/arm64-v8a/libreactnative.so' from inputs:

For temporary fixing it, you can do this:

./node_modules/realm/binding/android/build.gradle

Add this one line in the excludes array.
packagingOptions {
excludes = [
"META-INF",
"META-INF/",
"/libc++_shared.so",
"/libfbjni.so",
"/libjsi.so",
"/libreactnativejni.so",
"/libturbomodulejsijni.so",
"**/libreactnative.so", //Add this line
]
}

For whatever reason I also had to change "/libjsi.so" to "**/libjsi.so".
