With the increasing use of AI coding agents it becomes even more important to have UI unit tests for your mobile projects that the agent can run to verify everything still working as expected (or at least for non-UI related changes it's making!).
How to Deep Link Into iOS & Android With Compose Multiplatform youtube.com/watch?v=9XMN2n…
Any recommendations for which Pixel 10 device to get? Was tempted to get the Fold but looks like camera on "normal" Pixel 10 Pro is a good bit better (e.g. 100x zoom).
Mixing the Secret AI Sauce: How to design a flexible, graph-based strategy in Koog by @Ololoshechkkin medium.com/@vadim.brilian… Next article in the series. Nice overview of how to setup strategy graphs (using custom and built-in nodes...and useful subgraphWithTask abstraction)
📹 Recorded a quick video with the great @brwngrldev explaining and demoing MCP support in Android Studio -> youtube.com/watch?v=B-wzYo…
Why JetBrains’ Koog is The Most Advanced JVM Framework For Building AI Agents medium.com/@vadim.brilian…

AndroidX goes multiplatform #KMP youtu.be/jDz_yNZkEzk?si…
I wonder what an advanced alien race would think if they discovered Earth and saw that we intentionally slaughter and starve children.
Koog 0.4.0 Is Out: Observable, Predictable, and Deployable Anywhere You Build blog.jetbrains.com/ai/2025/08/koo… Great to see that it also now supports running on iOS (btw 0.4.1 version out just now that has fix for publication of iOS target)
It's so cool to see the unrelenting progress of Kotlin and Compose Multiplatform....all the moving pieces steadily coming together!
Today's #JetpackReleaseNotes include Wear Compose 1.5.0 with Material 3 Expressive, more KMP targets in Lifecycle 2.9.3, SavedState 1.3.2, Paging 3.4.0-alpha03, and Navigation3 1.0.0-alpha08 plus the first Material3+Navigation3 alpha! developer.android.com/jetpack/androi…
Cool to see Compose Multiplatform version of Navigation 3 library now available (in dev version so far). #CMP github.com/JetBrains/comp…

It's tough competition for the worst of these but how callous and inhumane do you have to be that this is what you try to jump on when you see a picture of a skeletal, starving child. "That starving child is sitting next to a parent who isn’t starving"
