@ColtonIdle are agents bad at it?

[Jose Alcérreca @ppvi]

We're constantly evaluating the official Android skills but we don't only look at correctness. If a skill gets you there in less time or using fewer tokens, it's a win.

More about how we think about skills in https://t.co/ceJLpWACSz

[Rebecca Franks @riggaroo]

We've just released a new official Android skill that can be used to statically analyse your #JetpackCompose code for performance improvements. ⚡️

Install it, and ask your agent to run the skill on your code. 🧑‍💻

We've seen some good results running it internally - give it a try and let us know any feedback!

This is based on an old project that required 50GB of RAM (all of @openstreetmap 's data) to run. I created a road simplifier in Rust to keep each region below 10MB of WASM. This was extremely fun to build.

[Jose Alcérreca @ppvi]

I made a convergence roadmap generator that works in the browser and lets you download printable, high-res images of 15 different regions.

That video was created by Claude just from screenshots and in two prompts, and it's definitely unoriginal and derivative, but so good for a tweet.

[Jose Alcérreca @ppvi]

@uecchi No, it's a different implementation, curated, and runs locally.

[Jose Alcérreca @ppvi]

@csinco @hamen @FMuntenescu So it's a collection of tools tailored to a specific PHP framework, including vectorized docs? Neat idea :P

📹 Recorded a quick video with the great @brwngrldev explaining and demoing MCP support in Android Studio -> https://t.co/mqoLn4NWkL

[Jose Alcérreca @ppvi]

@ColtonIdle @AndroidDev Thank you @ColtonIdle !

[Jose Alcérreca @ppvi]

📹 The second video talks about specific techniques and tools that you can use, like screenshot testing or GMD.

🧪 Why do we test? 📹 Scalable Testing Strategies I recorded these videos to help beginners understand the importance of testing, providing a starting point for useful tests that give the right amount of feedback at the right time.

Any recommendations for open-source dashboards that show test results and test history? Allure Report maybe? It hasn't been updated in 6 months and I'm struggling to generate reports for instrumented tests.

[Jose Alcérreca @ppvi]

@okatrych It doesn't work from the X app but it does from the website.

Anyway, my handle is https://t.co/XbYyWnCSDZ

Am I punished by 3L0n if I recommend every #AndroidDev to move to another, more open, social network?
