Tweaking Paged Items after they load can be overwhelming in Paging 3. Most advice suggests changing the data source, but for small tasks, it's overkill. Tap the article to check out a way to do it without data source modifications. medium.com/p/223f0bea603b #AndroidDev #Kotlin
"Do I need to learn XML or go straight into Compose?" I got this questions quite often in DM. Let's answer it once and for all. Now, I get it. Jetpack Compose is the new hotness. It's declarative, it's sleek, and it promises to make UI development smooth and easy. But let's pump the brakes for a moment and look at the bigger picture. Firstly, if you're getting into Android development today, it's pretty tempting to want to jump straight into the latest and greatest tech. Trust me, I feel you. But – and it's a big but – you've got to consider the ecosystem you're stepping into. You see, XML-based layouts have been around for YEARS. That means there are literally thousands of projects out there, sitting in repositories, being maintained and updated, that are built with XML. What happens when you land a job and they're like, "Hey, can you fix this bug in our 5-year-old app?" That's right, you're gonna work with XML. Real talk: learning XML is about practicality. It's about being the dev who can handle whatever's thrown their way, not just the shiny new stuff. You're gonna work with legacy projects. That's not a possibility; that's a guarantee. So here's the deal: don't sell yourself short by focusing only on what's new and trendy. Be the complete Android developer. Learn XML, get good at it, and then, by all means, dive head-first into Jetpack Compose. That way, whether you're dealing with an app that's been around since the Ice Age or creating something fresh and new, you've got all the tools you need to succeed. To sum it up: Do you need to learn XML or go straight into Compose? The answer, my friends, is a resounding "both."
