🧟♂️The 7 Silent Killers of Android Memory. The Zombie Leaks That Refuse to Die🚨 🧠 Even with Jetpack Compose and Coroutines, memory leaks are still haunting Android apps (*_*) just sneakier than ever. If your app slows down or crashes over time, you might be bleeding memory. ⚠️7 Leak Culprits (and Fixes) 1️⃣ Static Contexts & Singletons 🏛️ ❌ Holding an Activity in a static field = permanent leak. ✅ Use applicationContext for non-UI tasks. 2️⃣ Coroutines Gone Wild 🚦 ❌ Using GlobalScope for UI work keeps jobs alive after destroy. ✅ Use lifecycleScope or viewModelScope. 3️⃣ Flow Collection Leaks 🔄 ❌ Collecting without lifecycle awareness. ✅ Use repeatOnLifecycle(State.STARTED) or collectAsStateWithLifecycle(). 4️⃣ Compose Side Effects 🌀 ❌ Listeners without cleanup. ✅ Use DisposableEffect with onDispose. 5️⃣ Listeners & Receivers 📡 ❌ Forgot to unregister = leaked context. ✅ Always unregister in onPause() / onDestroy(). 6️⃣ Inner Classes 🏡 ❌ Non-static inner class holds Activity reference. ✅ Make it static + WeakReference. 7️⃣ Heavy Bitmaps 🖼️ ❌ Full-size images blow up memory. ✅ Use Coil or Glide to handle scaling & caching. 🔥Pro Tip: Memory leaks don’t crash your app overnight, & Memory leaks don’t appear on day one 💪. 👉 They quietly kill your app’s performance 👉 Stay clean.

Ever built an Android app that turned into a 𝙈𝙖𝙨𝙨𝙞𝙫𝙚 𝘼𝙘𝙩𝙞𝙫𝙞𝙩𝙮 doing everything? Its the core problem with early MVC architecture. Everything from UI to logic to data lived inside one class. Apps became messy, hard to test, and even harder to maintain. That’s when 𝗠𝗩𝗣 (𝗠𝗼𝗱𝗲𝗹-𝗩𝗶𝗲𝘄-𝗣𝗿𝗲𝘀𝗲𝗻𝘁𝗲𝗿) came into the picture. It was Android’s way of taking control back. In my previous article, I talked about how MVC shaped Android’s beginnings. Now, in this new one, I explore how MVP refined those ideas, fixed MVC’s pain points, and brought clarity, testability, and structure to Android apps. 🔗 Read it here: https://lnkd.in/ggQHv_uN #AndroidDevelopment #MVP #MVC #CleanArchitecture #AndroidArchitecture #MobileDevelopment

Just published a new article on why MVI is a better choice than MVVM for large-scale Android apps. Especially with Jetpack Compose. One of the biggest advantages? ✅ Compose is state-driven, and MVI gives you a single immutable UIState instead of juggling multiple LiveData or mutable fields. No partial recompositions, no LiveData observers, no event wrappers—just predictable state → UI rendering. If you're working with Compose or building modular apps, MVI scales cleaner, debugs more easily, and eliminates UI inconsistency. #android #kotlin #coroutine #mvi #mvvm

🧠 How to Decrease App Hangs in Android using the Latest Architecture If your Android app hangs or freezes, it’s not always the UI’s fault — it’s the architecture. Most developers still mix UI, logic, and data calls in one place. That’s a performance trap. Here’s how modern Android architecture fixes it 👇 1️⃣ Use Jetpack Compose with MVVM (or MVI) Separate UI from logic. Keep your composables stateless and manage state via ViewModel using Kotlin Flows or StateFlow. 2️⃣ Leverage Coroutines for Asynchronous Work Never block the main thread. Use withContext(Dispatchers.IO) for network/database calls and Dispatchers.Main.immediate only for UI updates. 3️⃣ Adopt Room with Paging 3 Large data sets shouldn’t freeze UI. Paging loads content gradually, keeping memory and CPU usage light. 4️⃣ Use WorkManager for Background Tasks Avoid manually managing threads — WorkManager ensures reliability even if the app restarts. 5️⃣ Measure with Android Profiler Detect jank, skipped frames, and heavy allocations. Optimize where it actually matters. 💡 Modern architecture isn’t about structure — it’s about smooth, responsive UX. #Android #JetpackCompose #Kotlin #Architecture #AppPerformance #ZiaShahid

🔴 From Views to Compose — Modernizing Android UI: Over the years, I’ve built Android apps with both the traditional View system and Jetpack Compose, and the difference is striking. With the View system: • UI is defined in XML and updated imperatively. • Works reliably but can become verbose and hard to maintain, especially with dynamic layouts. Switching to Jetpack Compose changed how I think about UI: • Declarative and state-driven, making UI reactive and predictable. • Reduces boilerplate — no more findViewById or manual view updates. • Integrates naturally with Kotlin and coroutines, making async UI flows seamless. • A simple, readable, and reactive UI — no XML, no manual updates. What I learned: Compose makes building dynamic, reactive UIs much easier and cleaner. The traditional View system still works for legacy apps, but it can slow down development. Embracing Compose improves readability, maintainability, and reduces bugs. For modern Android apps, Compose isn’t just a tool — it’s a paradigm shift. #Android #JetpackCompose #Kotlin #ViewSystem #CleanCode

🟣 remember vs rememberSaveable in Jetpack Compose Both look similar — but behave very differently 👇 ⚡ remember → Keeps state only in memory. Lost on screen rotation or process kill. ⚡ rememberSaveable → Persists state across configuration changes and process death using a Bundle. 💡 Rule of thumb: Use remember for temporary UI state. Use rememberSaveable for user input or data that should survive recreation. Example: var name by rememberSaveable { mutableStateOf("") } Simple, powerful — and essential for modern Jetpack Compose apps. 🚀 #Android #JetpackCompose #Kotlin #AndroidDevelopment #StateManagement #MobileDevelopment #ComposeTips
