The setup mirrors .gitignore syntax: Gemini won't see those files, but still understands the rest of your codebase. Fine-grained control. Best of both worlds. For more tips like these — www.jetpackcompose.app/newsletter

When does onAbandoned happen? When the effect was never successfully "remembered" - rare, but possible. If correctness is critical, you need to handle both cases explicitly:

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. Thread on lightweight library design 🧵 #AndroidDev

Key lesson: In hot code paths, the compiler can't always optimize for you. Sometimes you need to get your hands dirty and inline manually. Tools like Kotlin Explorer help you peek at generated code and find opportunities.

Romain rewrote it as one inline helper (resetToPivotedTransform) and slashed the cost to: 168 instructions, 1 branch Just 15% of the original work. 6× faster

As Android OG @ryan.harter.us puts it: "While AI can help solve some development problems, the real difference between mediocre apps and great apps isn't something I believe AI will be able to tackle in the foreseeable future."

JetpackCompose.app @jetpackcomposeapp.bsky.social · 18/11/2025

The difference between mediocre apps and great apps isn't code quality. It's understanding your customer and the problems they need solved. Thread on where Android developers still have the most leverage in this new era of software engineering 🧵 #AndroidDev

Why Android developers like cooking: 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 😭😭 #AndroidDev

"For the first time, an app built in 2021 would look nearly identical to an app built in 2025" This from Gabriel Peal perfectly captures where Android is now. We're not chasing new primitives anymore. We're refining and building on a mature foundation. 🧵 #AndroidDev

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. #AndroidDev

Finally, Compose is catching up to what designers have been doing in Figma for years. Beautiful UI shouldn't require a PhD in Canvas drawing. Want to know about feature like these, early? Read Dispatch www.jetpackcompose.app/newsletter

Compose 1.9 alpha just dropped two modifiers that'll make your designer's heart skip a beat: Modifier.dropShadow() Modifier.innerShadow() No more hacky Canvas drawing or third-party libraries. Native shadows are HERE. 🧵 #AndroidDev #JetpackCompose

The August '25 Compose release dropped 2D scrolling, better prefetching, and autoSize text. But the coolest feature? A modifier that tracks visibility WITHOUT killing your performance. Thread on onLayoutRectChanged 🧵 #AndroidDev #JetpackCompose

🤯 Mind-blowing fact: Both OpenAI's and Anthropic's official JAVA SDKs are written entirely in Kotlin. Let that sink in. Companies building SDKs FOR Java developers chose Kotlin as the implementation language. The Kotlin takeover is real 🫡 #AndroidDev

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 🧵 #AndroidDev

JetpackCompose.app @jetpackcomposeapp.bsky.social · 05/11/2025

Even better: Built-in DI support (Hilt & Koin extensions) and works across all Compose Multiplatform targets. Plus it's Chris Banes approved, which is basically a seal of quality in the Android world.

Use cases are endless: Dialog ViewModels that clean up when dismissed LazyColumn items with their own business logic Reusable components with isolated state Multi-pager screens with per-page ViewModels

Resaca lets you scope ViewModels to individual composables:

JetpackCompose.app @jetpackcomposeapp.bsky.social · 05/11/2025

ViewModel scoping in Compose has been broken from day one. You can only scope to Activity or navigation graphs, but Compose wants fine-grained components. Enter Resaca - the library that fixes this beautiful mess 🧵 #AndroidDev #JetpackCompose
