Abstract Not so long ago, working with Compose Multiplatform previews could feel… character-building. Previewing composables from common code often meant jumping through awkward hoops. On top of that, the tooling was lacking in features that Jetpack Compose tooling already had in place for a while. Over the past year, that’s changed drastically. We’ve got a new KMP plugin, CMP preview support in common code, Hot Reload, and a lot more refreshing updates.

Debugging user issues gets so much easier when you can see exactly what they experienced. While off-the-shelf solutions exist to integrate screen recording into our apps, they didn’t give us the quality, flexibility, or control we needed. So, our team built our own native, in-app session recording tool for Android. In this talk, we’ll share why we decided to go in-house, how we tackled the technical and UX hurdles along the way, and what we learned about recording high-quality video and audio data.
