How to disable Crashlytics during development
Debugging mobile applications, especially during active development, can be a complex process. Crash reporting tools like Crashlytics are invaluable for catching errors in production, but can become noisy and distracting during development phases. Therefore, understanding how to disable Crashlytics during development is crucial for streamlining your workflow and focusing on immediate debugging tasks. This allows developers to isolate issues they are actively introducing without being flooded with reports from previous states or intentional test crashes. Effectively managing Crashlytics ensures cleaner logs and a more focused development environment, leading to faster iteration and higher quality code. Failing to do so can lead to alert fatigue, missed genuine production issues, and wasted time sorting through irrelevant crash reports.
Why Disable Crashlytics During Development?
The primary reason to disable Crashlytics during development is to avoid cluttering your crash reporting dashboard with irrelevant data. When actively coding and testing new features, developers frequently introduce temporary bugs or intentionally trigger error conditions for testing purposes. These actions generate crash reports that, while useful in production, simply add noise to the development workflow. This “noise” can obscure genuine issues that need immediate attention, making it harder to identify and resolve critical bugs before they reach end-users. Moreover, constantly receiving crash notifications for known issues can be disruptive and decrease developer productivity.
Consider a scenario where a developer is implementing a new API integration. During the initial phase, they may intentionally cause network errors to test the application’s error handling capabilities. These intentional errors would generate crash reports in Crashlytics. If Crashlytics isn’t disabled, these reports would mix with real crashes, making it difficult to discern the actual bugs from the expected test outcomes. Disabling Crashlytics in development allows the developer to focus solely on the immediate debugging tasks at hand, avoiding distractions and ensuring that the crash reporting system remains relevant for production environments.
Furthermore, disabling Crashlytics during development aligns with best practices for maintaining a clean and reliable crash reporting system. A well-managed Crashlytics instance should primarily reflect the real-world user experience, providing actionable insights into production-level issues. By filtering out development-related crashes, you ensure the data in Crashlytics is accurate and representative of the application’s performance in the hands of your users. This, in turn, leads to more effective bug fixing and a better overall user experience.
Methods for Disabling Crashlytics
There are several approaches to disable Crashlytics during development, each with its own advantages and disadvantages. One common method is to use conditional compilation, which involves wrapping the Crashlytics initialization code within preprocessor directives that only execute in specific build configurations. This approach allows you to completely exclude Crashlytics from the debug build, ensuring that no crash reports are generated during development.
Another method involves programmatically disabling Crashlytics based on the application’s build type. This can be achieved by checking the application’s build configuration at runtime and calling a function to disable Crashlytics if the application is running in a debug environment. This approach is more flexible than conditional compilation, as it allows you to easily switch between enabling and disabling Crashlytics without modifying the build configuration. For example, you might want to enable Crashlytics temporarily in a debug build to test a specific error scenario.
A third option is to use different Firebase projects for development and production environments. This approach provides complete isolation between the two environments, ensuring that no development-related crashes ever reach the production Crashlytics dashboard. While this method requires more setup and configuration, it offers the highest level of separation and is often the preferred approach for larger teams with complex development workflows. According to Firebase documentation, “Using separate projects prevents accidental data pollution and allows for more controlled testing.” Firebase Project Types
Step-by-Step Guide to Disabling Crashlytics Using Conditional Compilation
Conditional compilation is a powerful technique to disable Crashlytics during development. This method uses preprocessor directives to include or exclude code based on the build configuration. Here’s a step-by-step guide on how to implement this:
- Define a Debug Flag: In your build settings, define a custom flag (e.g., DEBUG) for your debug build configuration. This flag will be used to conditionally compile the Crashlytics code.
- Wrap Crashlytics Initialization: Surround the Crashlytics initialization code with if DEBUG and endif preprocessor directives. This ensures that the code is only compiled when the DEBUG flag is defined.
- Test Your Implementation: Build and run your application in both debug and release configurations to verify that Crashlytics is disabled in debug and enabled in release.
Here’s an example of how this might look in Swift:
if DEBUG print("Crashlytics disabled in debug mode") else FirebaseApp.configure() // Initialize Crashlytics endif
This code snippet demonstrates how to effectively use conditional compilation to exclude Crashlytics initialization from debug builds. By implementing this approach, you can maintain a clean and focused development environment without being overwhelmed by irrelevant crash reports. It’s a simple yet powerful technique for managing Crashlytics in your mobile application projects.
Best Practices and Considerations
When implementing a strategy to disable Crashlytics during development, consider these best practices to ensure a smooth and effective workflow. First, document your approach clearly in your project’s documentation. This ensures that all team members understand how Crashlytics is managed and can correctly configure their development environments. Consistent documentation reduces confusion and prevents unintentional enabling of Crashlytics in debug builds.
Second, establish a clear policy for when and how Crashlytics should be enabled during development. For example, you might want to temporarily enable Crashlytics in a debug build to test a specific error scenario or to gather data on a particular feature. However, it’s important to disable it again once the testing is complete to avoid cluttering the crash reporting dashboard. A defined policy helps maintain a balance between the benefits of crash reporting and the need for a clean development environment.
Finally, regularly review your Crashlytics configuration and ensure that it aligns with your development workflow. As your project evolves, your needs may change, and you might need to adjust your approach to disabling Crashlytics accordingly. For example, you might want to switch from conditional compilation to using separate Firebase projects if your team grows or if your development process becomes more complex. Regular reviews ensure that your Crashlytics setup remains optimized for your specific needs. According to a study by Raygun, effective crash reporting management can reduce bug resolution time by up to 30%. Raygun Crash Reporting

Question & Answer :
Is there any simple way to turn Crashlytics Android SDK off while developing ?
I don’t want it to send a crash every time I do something stupid
On the other hand I don’t want to comment out Crashlytics.start() and possibly risk forgetting to uncomment it and commit
I found the solution from Crashlytics (with Fabric integration)
Put following code inside your Application class onCreate()
Crashlytics crashlytics = new Crashlytics.Builder().disabled(BuildConfig.DEBUG).build(); Fabric.with(this, crashlytics);
EDIT:
In Crashalitics 2.3 and above, this is deprecated. The correct code is:
CrashlyticsCore core = new CrashlyticsCore.Builder().disabled(BuildConfig.DEBUG).build(); Fabric.with(this, new Crashlytics.Builder().core(core).build());
or
Fabric.with(this, new Crashlytics.Builder().core(new CrashlyticsCore.Builder().disabled(BuildConfig.DEBUG).build()).build());
(copied from Crashlytics deprecated method disabled())
EDIT2:
You can also optionally add this to your buildType in gradle. This command disables sending the crashlytics mapping file and generating an ID for each build, which speeds up gradle builds of those flavors. (It doesn’t disable Crashlytics at run time.) See Mike B’s answer here.
buildTypes { release { .... } debug { ext.enableCrashlytics = false } }
