Firebase Crashlytics is a real-time crash reporting and diagnostics service that helps developers monitor and improve app stability. It collects crash logs, stack traces, device metadata, and custom logging events, allowing teams to quickly identify and fix critical issues. Integrated tightly with Android, iOS, and Unity SDKs, Crashlytics supports alerting, release management, and issue prioritization. It can be connected with Firebase Analytics and Google Play for contextual debugging and tracking crash trends across versions and devices. Crashlytics also supports custom key logging and breadcrumb trails for complex bug analysis.

Firebase Crashlytics is partially functional in China. The SDK can collect crash logs locally, but uploading reports to Firebase servers hosted on Google infrastructure is unreliable due to network restrictions. Depending on user location, device network, and regional firewalls, reports may be delayed, incomplete, or entirely lost. The Firebase Console for viewing reports is inaccessible without circumvention tools, making real-time monitoring impractical for local teams. Developers targeting China often adopt domestic crash reporting services such as Bugly (by Tencent), Baidu MTC, or Aurora’s crash service (极光崩溃分析), which offer similar analytics, alerting, and integration with Chinese device ecosystems. These services support Huawei, Xiaomi, and other local brands more effectively, and comply with China’s network security and data localization laws. For international apps deployed globally, developers often implement dual reporting logic—sending crash logs to Firebase outside China and to a local service when inside China.

The information regarding service availability in China is provided for general reference purposes only. Due to the dynamic nature of network conditions and regulatory environments, the actual accessibility of these services may vary over time and by location. Users are advised to verify the current status independently.
