Mastering @Stable in Jetpack Compose for Better UI Performance

Görkem Kara — Wed, 23 Oct 2024 07:23:37 +0000

Mutable objects often lead to unexpected UI updates in Jetpack Compose. By using @Stable, you can control when and how recompositions happen, ensuring a smoother experience.

But how exactly does @Stable work, and when should you use it over @Immutable?

Logcat is a staple in every Android developer’s toolkit. However, many devs might not know all its hidden features that can drastically improve their debugging efficiency. Let's explore some tips to make your Logcat debugging super smooth!

💡 Advanced Filtering for Better Focus

Stop getting lost in endless lines of logs! Utilize filters like package:yourapp and tag~:User to isolate the logs you actually care about. This will make your debugging process much more manageable.

🚨 Master the Log Levels

Do you know when to use warn vs. error? Understanding Logcat’s log levels (e.g., info, debug, verbose) can help you quickly catch the most important logs and track down issues faster.

🛠️ Key Shortcuts for Quick Debugging

Save time by learning shortcuts like Ctrl + Space to auto-complete filters and Alt + Enter to quickly toggle between different log levels. These little tricks can make a world of difference when you're debugging under pressure.

By following these tricks, you'll be able to optimize your Logcat debugging process and write more efficient code! 💡👨‍💻

Handling null + null in Kotlin: What Happens?

Handling `null + null` in Kotlin: What Happens?

When developing in Kotlin, you're bound to run into scenarios involving null values. Kotlin's approach to null safety is well-known, but what happens when you try to add null + null? Let's explore this seemingly simple yet thought-provoking situation!

Kotlin and Null Safety

Kotlin’s compiler is strict when it comes to handling nulls. It doesn't let you add null values without clear handling. But what if you attempt to add null + null? 🤔 The compiler won't just sit back—it will prompt you to handle it, either by using safe calls (?.) or the Elvis operator (?:). This is part of Kotlin's type safety design.

For a deeper understanding of Kotlin null safety and best practices, check out my blog post:

The Case of `null + null`

When you try to add null + null in Kotlin, an error will occur. The language enforces clear handling of nulls to prevent unexpected behaviors or crashes in your application. This is especially important in Android development.
