Instabug is a crash reporting tool that provides detailed reports on app crashes, including stack traces and symbolicated/deobfuscated frames. To access these reports, developers need to upload reference files such as Debug Symbol files (dSYM) for iOS or mapping files for Android. These files are used to attribute memory addresses in the crash report to their corresponding functions and methods. The process of uploading these files can be automated, and Instabug also provides a sandbox and demo options to help developers get started with its features. Once the reports are uploaded, they provide detailed information on the app's conditions leading up to the crash, including network request logs and steps to reproduce the crash, which helps in diagnosing issues and maintaining industry-leading apps.
