How to implement Firebase Crashlytics with React Native apps

While there are official documentations about implementing Firebase Crashlytics, our focus here is to highlight the key factors to consider when implementing it in React Native. These insights will help you seamlessly integrate Crashlytics into your React Native application, ensuring you get the most out of its powerful crash reporting and monitoring features.

Here are some key things to know about implementing and using Firebase Crashlytics in a React Native mobile application:

1. Setup and installation

• Install necessary packages: You need to add Firebase and Crashlytics packages to your project.

• Configure Firebase: Set up Firebase in your project by adding configuration files for both Android and iOS.

• Follow platform-specific steps: Each platform (Android and iOS) has specific steps you need to follow to complete the setup.

2. Automatic crash reporting

• Automatic capture: Crashlytics automatically captures and reports crashes in your app.

• Data collection: It collects information like error details, device type, and app version to help you understand the crash.

3. Manual error logging

• Log non-fatal errors: You can manually log errors that don't crash the app but are still important.

• Useful for debugging: This helps you catch and report issues that you handle within your code.

4. Custom keys and logs

• Add context: You can add custom information to crash reports, like user actions or specific app states.

• Detailed logs: This additional context helps you understand what was happening in the app before the crash.

5. User identification

• Track specific users: You can set user IDs to see if specific users are experiencing issues.

• Helps with support: This is useful for customer support and debugging user-specific problems.

6. Opt-out mechanism

• User privacy: Provide an option for users to opt-out of crash reporting if they prefer.

• Compliance: This helps you comply with privacy regulations and respect user choices.

7. Testing crash reporting

• Test crashes: You can force crashes to test if Crashlytics is working correctly.

• Verify setup: Ensure that crashes appear in the Firebase Console to confirm proper setup.

8. Performance considerations

• Minimal impact: Crashlytics is designed to have a minimal impact on your app's performance.

• Asynchronous operations: It works in the background, so it doesn't slow down your app.

9. Versioning

• Keep updated: Always use the latest version of the Crashlytics SDK for new features and fixes.

• Compatibility: Ensure compatibility with your React Native version.

10. Dashboard usage

• Analyze crashes: Use the Firebase Console to view and analyze crash reports.

• Prioritize issues: Identify and prioritize issues based on their impact on users.

11. Symbolication

• Readable reports: For iOS, ensure you upload dSYM files, and for Android, ensure ProGuard is configured, so crash reports are readable.

• Automatic uploads: Set up automatic uploads of these files to make the process easier.

12. Integration with other Firebase services

• Enhanced insights: Combine Crashlytics with other Firebase services like Analytics for deeper insights.

• Comprehensive monitoring: Use Performance Monitoring to track app performance alongside crash data.

13. Handling JavaScript errors

• Global error handling: Set up a global error handler to catch and report JavaScript errors.

• Complete coverage: This ensures that both native and JavaScript errors are reported.

Enhancing crash analysis with UXCam

To enhance your crash analysis capabilities in React Native, integrating UXCam can provide you with deeper insights into user behavior and app performance leading up to crashes. Here’s a focused guide on how to combine these powerful tools effectively.

Integrate UXCam into your mobile app

To get started with UXCam, follow these steps:

• Register and set up your account on UXCam for free.

• Install UXCam by adding the UXCam SDK to your project. You can do this using npm or yarn.

• Configure UXCam in your project by initializing it with your app key. This can be done in your main app file.

Link UXCam with Firebase Crashlytics

Enhancing Firebase Crashlytics with UXCam data involves ensuring that critical user actions and crashes are logged accurately:

• Log Important User Actions: Use UXCam to log significant events in your application. This could include button taps, page views, or other interactions.

• Record Sessions: UXCam automatically records user sessions, but you can tag specific user actions or crashes with custom event logs to provide context to the recordings. These recordings can be invaluable for reproducing and understanding the user actions leading up to a crash.

• Sync UXCam with Crash Reports: Ensure that each crash report in Firebase Crashlytics is accompanied by a UXCam session URL. You can achieve this by capturing the URL from the current session right before logging a crash.

Analyze crashes with enhanced data

Access and review enhanced crash reports

Once you have integrated UXCam with Firebase Crashlytics, your crash reports will be enriched with additional contextual data from UXCam. Here’s how to access and utilize this enhanced data:

• Access crash reports in Firebase console: Begin by viewing the crash incidents reported in the Firebase console. Each report will now include custom logs that contain UXCam session URLs.

• Review UXCam sessions: Follow the UXCam session URLs embedded in the crash reports to watch video recordings of user sessions leading up to the crash. These recordings can reveal user interactions, screen transitions, and the sequence of events that triggered the crash.

Deep dive into user interactions

UXCam’s recordings allow you to observe firsthand the user's actions that preceded the crash. This can be particularly useful for identifying non-obvious UI issues or replicating specific scenarios that are difficult to deduce from traditional logs alone.

• Identify UI elements and interactions: Look for any interactions with UI elements that might have been misbehaving or causing an overload, such as a button that users repeatedly tapped with no response.

• Monitor for UI freezes: UXCam can help identify any UI freezes that occur before a crash. These events are crucial for understanding if the crash was due to UI thread blockages or other performance bottlenecks.

Leverage UXCam’s analytical tools

UXCam offers tools that go beyond simple session recordings:

• Heatmaps: Utilize UXCam’s heatmap feature to see which areas of your app receive the most interaction. This could help in pinpointing if a frequently used area of your app is prone to crashes.

  

  

• User journeys: Analyze the paths users take within the app to see if certain journeys lead to crashes more often than others. This analysis can reveal design flaws or points where the app’s performance starts degrading.

Correlate UX Insights with technical logs

Integrate the insights gained from UXCam with the technical data provided by Firebase Crashlytics:

• Cross-reference data: Compare UXCam’s qualitative data with the quantitative data from Firebase. For instance, if a crash consistently occurs after a particular type of interaction recorded by UXCam, you can cross-reference this with the logs collected at the moment of the crash in Firebase.

• Analyze trends: Look for trends over time in both UXCam and Firebase data. Are there specific releases or updates after which the frequency of certain crashes increased? This can guide future development priorities and testing.

Act on the insights

Finally, use the insights gained from this enriched crash analysis to make informed decisions:

• Prioritize bug fixes: Identify which crashes are affecting the most users or causing the most significant disruptions, and prioritize these for fixes.

• Improve UX design: Adjust your app’s design and user flow based on the user behavior insights from UXCam to prevent future crashes.

• Enhance performance monitoring: Regularly review the combined insights from UXCam and Firebase Crashlytics to keep a pulse on your app’s performance and stability.

Comparing UXCam and Crashlytics data for better insights

When working with both UXCam and Crashlytics, understanding the capabilities and benefits of each can help you harness their combined power for more comprehensive app insights.
