How we built user interaction tracking for Jetpack Compose

Knowing the user interactions which happened in your app right before it crashed is crucial context information for fixing errors. Tracking interactions like click and swipes manually can be tedious, so we at sentry looked into ways on how to do that automatically for your Jetpack Compose enabled Android app. Learn how you can intercept any touch event, how to determine Composable identifiers and ultimately how our sentry Android SDK ties it all together.

Code Mappings and Why They Matter
Product Updates

Code Mappings and Why They Matter

Code Mappings connect errors to the source code in a repository. And since errors can have paths that are different from the tree structure of the repository, Code Mappings determines the accurate path through a combination of a repository URL and a path transformation. Sentry uses Code Mappings to serve issue context on the issue details page.
