Crashlytics runs in the background to monitor app crashes and errors. It uses minimal CPU and memory, so it does not affect your app's frame rate or battery life noticeably. However, excessive logging or sending large crash reports can slightly increase network usage and delay app startup if not configured properly.
To keep your app running smoothly at 60fps, initialize Crashlytics asynchronously during app startup. Avoid heavy logging on the main thread. Use Crashlytics' built-in logging methods sparingly and only log essential information. Disable debug logging in production builds to reduce overhead.
Adding Crashlytics increases your app size by a few megabytes, typically under 5MB. This is considered small to medium impact. The SDK is optimized to load quickly, so startup time impact is minimal if initialized correctly. Avoid initializing Crashlytics multiple times or on heavy UI threads to prevent startup delays.
Crashlytics is available on both iOS and Android with similar features. On Android, it integrates with Kotlin or Java and uses Firebase SDK. On iOS, it integrates with Swift or Objective-C and uses Firebase iOS SDK. Both platforms require proper configuration of Google services files and permissions. Crash reporting behavior and network usage are consistent across platforms.
Both Google Play and Apple App Store require apps to handle user data responsibly. When using Crashlytics, disclose crash data collection in your privacy policy. Ensure you comply with data protection laws like GDPR by allowing users to opt out if needed. Crashlytics does not collect personal user data by default, but review your logging to avoid sensitive info.
If Crashlytics is causing slow load, you might be initializing it on the main thread or logging too much data synchronously. Check that Crashlytics initialization is done asynchronously and logging calls are minimal and off the UI thread. Also, verify network connectivity and SDK version to avoid delays.
