Steps to Reproduce

Description

When upgrading to @sentry/react-native@8.0.0 with the recommended sentry-android-gradle-plugin:6.0.0, the Android app crashes on launch with a "mixed versions" error. The Gradle Plugin 6.0.0 pulls in Sentry Android SDK version 8.31.0, but the React Native SDK expects version 8.32.0 or higher.

Reproduce

1. Upgrade @sentry/react-native from 7.x to 8.0.0
2. Update sentry-android-gradle-plugin to 6.0.0 as per migration guide
3. Run pnpm install
4. Build Android app
5. Launch the app on an Android device

Expected Result

The app should launch successfully with Sentry initialized without version conflicts.

Actual Result

The app crashes immediately on launch with the following error:

  F Sentry  : The Sentry SDK has been configured with mixed versions. Expected maven:io.sentry:sentry-android-fragment to match core SDK version 8.32.0 but was 8.31.0
  F Sentry  : The Sentry SDK has been configured with mixed versions. Expected maven:io.sentry:sentry-compose to match core SDK version 8.32.0 but was 8.31.0

  E AndroidRuntime: java.lang.IllegalStateException: Sentry SDK has detected a mix of versions. This is not supported and likely leads to crashes. Please always use the same version of all SDK modules (dependencies).

  io.sentry.react.RNSentryModuleImpl.initNativeSdk(RNSentryModuleImpl.java:173)
  io.sentry.react.RNSentryModule.initNativeSdk(RNSentryModule.java:42)

Workaround

Add explicit dependency overrides in android/app/build.gradle:

dependencies {
    // ... other dependencies

    // Force Sentry Android SDK versions to match React Native SDK 8.0.0 expectations
    // The gradle plugin 6.0.0 pulls in 8.31.0, but we need 8.32.0+
    implementation("io.sentry:sentry-android:8.32.0")
    implementation("io.sentry:sentry-android-core:8.32.0")
    implementation("io.sentry:sentry-android-fragment:8.32.0")
    implementation("io.sentry:sentry-android-compose:8.32.0")
}

After adding these overrides and running a clean build (./gradlew clean), the app launches successfully.

Hi and sorry for your experience :(
We will investigate what's the best short fix for this for now

[Wiingaard]

I just updated Sentry Android Gradle Plugin 6.1.0 which seems to have fixed the issue without needing the mentioned workaround.
