New 6.0.0-rc.1 broke Android builds in React Native

[brunofurmon]

Summary

react-native-mparticle@2.7.13 fails to compile on Android because it imports com.mparticle.UserAttributeListener, which was removed in com.mparticle:android-core:6.0.0-rc.1 (published to Maven Central on 2026-05-22).

The library's Android build.gradle declares its mParticle dependency with an open-ended dynamic version range:

compileOnly 'com.mparticle:android-core:[5.9.3, )'

Gradle's dynamic version resolution picks the highest available version — including pre-releases — so every fresh build now pulls in 6.0.0-rc.1 and breaks. Consumers who had a successful build yesterday are now broken with no code change on their side.

Reproduction

1. Create a new React Native project (any RN version supported by the library).
2. Install the library:

   npm install react-native-mparticle@2.7.13

3. Add a minimal mParticle initialization in the host Android app (per the README). Pin any version of com.mparticle:android-core in app/build.gradle — the failure is independent of what the host app pins, because react-native-mparticle's own subproject resolves its compileOnly range separately.
4. Build a release variant:

   cd android && ./gradlew assembleRelease

5. Build fails during :react-native-mparticle:compileReleaseJavaWithJavac.

Expected

Library compiles against a known-good mParticle Android Core version.

Root cause

Two issues compound:

1. Removed API still referenced. MParticleModule.java uses com.mparticle.UserAttributeListener, which is no longer present in the 6.x line of com.mparticle:android-core.
2. Unbounded dynamic version range. The dependency declaration [5.9.3, ) lets Gradle silently jump across major versions (and into pre-releases like 6.0.0-rc.1). Any breaking change in a future major release will retroactively break every existing consumer of this library version.

Suggested fix

Short-term (unblocks consumers immediately):

• Cap the version range to the last known-compatible major:

  compileOnly 'com.mparticle:android-core:[5.9.3, 6.0.0)'

Long-term:

• Migrate the listener usage in MParticleModule.java to the replacement API in com.mparticle:android-core 6.x (e.g. UserAttributeListenerAsync / UserAttributeListenerSync, per the SDK's deprecation history).
• Cut a new release of react-native-mparticle pinned against a specific tested major.

Workaround for affected consumers

Force-pin the SDK in the host app's root android/build.gradle:

allprojects {
    configurations.all {
        resolutionStrategy {
            force 'com.mparticle:android-core:5.79.0'
        }
    }
}

Environment

• react-native-mparticle: 2.7.13
• com.mparticle:android-core resolved: 6.0.0-rc.1 (published 2026-05-22)
• Gradle: 7.x / 8.x (any version that supports dynamic ranges — i.e. all of them)
• Android Gradle Plugin: 7.4.2 (per the library's build.gradle)
