[Bug]: OneSignal 5.7.1 causes OkHttp runtime incompatibility crash in React Native app (NoClassDefFoundError okhttp3/internal/Util) #2575

What happened?

After upgrading react-native-onesignal from 5.3.2 to 5.3.3, our Android app started crashing at startup with:

java.lang.NoClassDefFoundError: Failed resolution of: Lokhttp3/internal/Util;

Sentry points to:

• okhttp3.JavaNetCookieJar.decodeHeaderAsJavaNetCookies
• com.facebook.react.modules.network.ReactCookieJarContainer.loadForRequest

The crash happens on the OkHttp dispatcher thread shortly after launch when network/cookie handling runs.

Environment:

• React Native: 0.84.1
• react-native-onesignal: 5.3.3 (problematic), 5.3.2 (works)
• OneSignal Android SDK transitively used by RN plugin:
  • 5.7.1 via RN OneSignal 5.3.3 (crashes)
  • 5.6.2 via RN OneSignal 5.3.2 (stable)

What we observed in dependency resolution:

• ./gradlew :app:dependencyInsight --configuration mojakrkaReleaseRuntimeClasspath --dependency com.squareup.okhttp3:okhttp
• Selected by conflict resolution: com.squareup.okhttp3:okhttp:5.2.1 (between 5.2.1, 4.9.2, 3.14.9)
• React Native networking stack still includes okhttp-urlconnection:4.9.2

This appears to create a runtime-incompatible mix that triggers the crash.

Steps to reproduce?

1. Use a React Native 0.84.x Android app with OneSignal integrated via react-native-onesignal.
2. Set react-native-onesignal to 5.3.3.
3. Build/install Android release app.
4. Launch app and let first network requests run (cookie handling path).
5. Observe crash: NoClassDefFoundError: okhttp3/internal/Util
6. Run dependency insight and observe resolved OkHttp 5.2.1.
7. Downgrade to react-native-onesignal@5.3.2 (OneSignal Android 5.6.2) and rebuild.
8. Crash disappears; OkHttp resolves to 4.9.2.

What did you expect to happen?

Upgrading OneSignal should not introduce a transitive dependency combination that causes runtime crashes in a standard React Native Android networking setup. The app should start and handle network/cookies without crashing.
