@sentry/react-native SDK Version

8.9.1

How does your development environment look like?

MacBook Pro M2  v15.7.4 (24G517)
Expo 54 (CNG)
Android SDK 36 + SDK Tools 36+35

Sentry.init()

  Sentry.init({
    integrations: [
      Sentry.breadcrumbsIntegration({ fetch: false, xhr: true }),
      Sentry.graphqlIntegration({ endpoints: [Env.EXPO_PUBLIC_API_URL + '/v2/graphql'] })
    ],
    dsn: Env.EXPO_PUBLIC_SENTRY_KEY,
    environment: Env.EXPO_PUBLIC_SENTRY_ENV,
    enabled: SENTRY_ENABLED_ENVS.includes(Env.EXPO_PUBLIC_NAME),
    sendDefaultPii: true,
    release: `${Application.applicationId}@${Application.nativeApplicationVersion}`,
    dist: Application.nativeBuildVersion || '1',
    appHangTimeoutInterval: 3,
    beforeBreadcrumb: (breadcrumb, _) => {
      if (breadcrumbToIgnore(breadcrumb)) {
        return null;
      }

      return withGraphQLBreadcrumb(withTouchBreadcrumb(breadcrumb));
    },
    denyUrls: [REACHABILITY_URL]
  });

Steps to Reproduce

1. Install only SDK 36 and SDK Tools 36 + 35
2. Update sentry from 7.x to 8.x
3. Try to build with any of available commands (directly gradle or expo ones)

Expected Result

1. Build completes without errors.
2. expo-handler from @sentry/react-native/android/expo-handler uses the safeExtGet to get the values

def safeExtGet(prop, fallback) {
    rootProject.ext.has(prop) ? rootProject.ext.get(prop) : fallback
}

Actual Result

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':sentry-react-native-expo:generateDebugRFile'.
> Failed to find target with hash string 'android-31' in: /Users/<user>/Library/Android/sdk

Error: /Users/<user>/Developer/mobile-app/android/gradlew app:assembleDebug -x lint -x test --configure-on-demand --build-cache -PreactNativeDevServerPort=8081 -PreactNativeArchitectures=arm64-v8a exited with non-zero code: 1

Proposed fix

It's fixed if setting that value to 36 instead of 31. So probably using safeExtGet in that subproject would be enough.
