feat(core): Expose `pauseAppHangTracking` and `resumeAppHangTracking` APIs by antonis · Pull Request #6192 · getsentry/sentry-react-native

📢 Type of change

Bugfix
New feature
Enhancement
Refactoring

📜 Description

Exposes the Cocoa SDK's SentrySDK.pauseAppHangTracking() and SentrySDK.resumeAppHangTracking() APIs to React Native users.

These methods allow temporarily pausing app hang detection — useful when showing system dialogs (e.g., permission prompts) that block the main thread but are not real hangs.

iOS: calls through to SentrySDK via SentrySDKWrapper
Android: no-op (app hang tracking is iOS-only; required by TurboModule spec)

New public API:

import { pauseAppHangTracking, resumeAppHangTracking } from '@sentry/react-native';

pauseAppHangTracking();
// ... show system dialog ...
resumeAppHangTracking();

💡 Motivation and Context

Closes #3909

The Cocoa SDK added pauseAppHangTracking / resumeAppHangTracking in v8.30.0 (we depend on 9.13.0). Without this, the SDK reports false-positive app hangs when the OS shows system dialogs that block the main thread.

💚 How did you test it?

Added wrapper unit tests (enabled/disabled paths)
All existing tests pass
Build, lint, circular dep check, and API report all green

📝 Checklist

I added tests to verify changes
No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled
I updated the docs if needed docs(react-native): Add pause/resume app hang tracking API sentry-docs#17817
I updated the wizard if needed.
All tests passing
No breaking changes
