Want Gemini in Android Studio but worried about sharing sensitive IP?
Use .aiexclude files—it's like .gitignore but for AI.
Your private code stays private while you still get contextually rich AI suggestions.

Most Android PDF libraries weigh 10-16MB because they bundle native C/C++ code.
Rajat Mittal built one that's 88 KILOBYTES. 🤯
How? By ditching native deps and using only Android's built-in PdfRenderer.

You peel the carrot, you chop the carrot, you put the carrot in the stew.
You don't suddenly find out that your peeler is several versions behind and they dropped support for carrots in version 4.3 😭😭

We're not chasing new primitives anymore. We're refining and building on a mature foundation. 🧵

Fun fact: toUpperCase() got deprecated because of... Turkey 🦃
Just kidding, not 🦃 but 🇹🇷
In Turkish, uppercase "i" is "İ" (with a dot!), not "I".
Since toUpperCase() relied on Locale.getDefault(), your code could behave differently depending on location.

But the coolest feature? A modifier that tracks visibility WITHOUT killing your performance.

We only scratched the surface with the previous post on Metro. @jingibus.bsky.social peels the onion and helps you understand what it takes to ship a project of this scale
This is fantastic and @zacsweers.dev deserves all the praise but it also is gonna give you a false idea of what Z is like as a maintainer and author, what the project is like, and how you might achieve something like this yourself
Hot take: Dependency Injection on Android just got a huge upgrade!!
Square just moved Anvil to maintenance mode to adopt Metro - a DI framework built by ONE PERSON that's 47-56% faster than Dagger+Anvil.
This is what "individual developers changing ecosystems" looks like 🧵
