Sentry.init()

init({
      dsn: SENTRY_DATA_SOURCE_NAME,
      environment: getEnv(),
      onReady: options.onReady,
      debug: true,
    });

Steps to Reproduce

1. In a React component, call a non-function property to force a crash:

export const ProfileScreen = () => {
  const { data: userData } = useValidateTokenQuery();
  // force a crash
  userData.data.phoneNumber();
  return <Text>Profile</Text>;
};

2. Run the app in release build on Android.
3. App crashes immediately.
4. Event is not visible in Sentry dashboard.

ios works as expected.

Sentry.nativeCrash() successfully sends crash reports on both Android and iOS. This shows that the Sentry setup (initialization, DSN, integrations) is working correctly, and the issue is most likely specific to handling fatal JS exceptions on Android.

Expected Result

Crash should be reported to Sentry dashboard (same as on iOS).

Actual Result

App crashes on Android, but no event is reported to Sentry.

RN-346 [android] Some fatal JS crashes not reported to Sentry dashboard (working on iOS)

[MarkusTrb]

Facing same issue on production Android app (SDK 6.19.0)

[philprime]

Thank you for raising this issue.

Can you reproduce the issue also with the next major version v7.1.0?
We already did quite some updates in between, so maybe it's already resolved there.

[bestofaIl]

Thank you for the quick response.

I tested the same scenario with v7.1.0, but unfortunately the result is the same — the crash on Android is still not reported to the dashboard (while on iOS it works as expected).

I also ran ./gradlew clean before building to make sure it’s not related to cached build artifacts.
