How do you handle React Native app crashes?

Question

Accepted Answer

**Error tracking setup:**
```tsx
import * as Sentry from "@sentry/react-native";

Sentry.init({ dsn: "YOUR_DSN" });
```

**Global error handler:**
```tsx
import { ErrorUtils } from "react-native";

const defaultHandler = ErrorUtils.getGlobalHandler();

ErrorUtils.setGlobalHandler((error, isFatal) => {
  if (isFatal) {
    Sentry.captureException(error);
    // Show crash dialog
  }
  defaultHandler?.(error, isFatal);
});
```

**Crash reporting:**
- Sentry: error tracking and performance
- Bugsnag: crash reporting
- Firebase Crashlytics: mobile-specific

**Best practices:**
- Log breadcrumbs before errors
- Attach user context
- Monitor crash rates
- Set up alerts for critical errors
