See what's happening in your app before your first line of code can even run.

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.

Jetpack Compose, a new declarative UI toolkit by Google made for building native Android apps, is rapidly gaining traction. The main advantage of using Jetpack Compose is that it allows you to write UI code that is more concise and easier to understand. This leads to improved maintainability and reduced development time.

The mobile development ecosystem has always been very diverse, arguably more diverse than the web development ecosystem. Both React Native and Flutter have a declarative approach from the start, but with Android and iOS now joining the declarative bandwagon, we can see that the future of mobile development is declarative.

Profilers measure the performance of a program at runtime by adding instrumentation to collect information about the frequency and duration of function calls. They are crucial tools for understanding the real-world performance characteristics of code and are often the first step in optimizing a program. In this post, we’ll walk through how we built Sentry’s iOS profiler, which is capable of collecting high quality profiling data from real user devices in production with minimal overhead.
