Building Android App in 24 Hours with Claude Code

Why is adding a library to an Android project still a manual chore? We’ve moved to modern tools like Version Catalogs and specialized compiler plugins, but the setup process hasn't caught up. Every time you want to try a new library, you’re forced into a ritual: 1. Finding the right version for your current environment. 2. Manually editing multiple blocks in your configuration files. 3. Solving the compatibility puzzle (KSP ↔ Kotlin ↔ AGP). 4. Repeating the same setup across modules. It’s not complex work, it’s just friction that breaks your creative flow. I decided to solve this by building the "Android Dependency Resolver" an IntelliJ & Android Studio plugin designed to turn minutes of configuration into a single click. 🚀 🛠 What makes it different: ✅ Project-aware suggestions: It analyzes your SDK, AGP, Gradle, and Kotlin setup to recommend versions that actually work. ✅ Automated setup: Updates Version Catalogs and Gradle files using structured IDE actions (no messy string replacements). ✅ Compiler alignment: Handles tricky cases like KSP where versions must match exactly. ✅ Up-to-date suggestions: Fetches the latest library metadata so you don’t have to manually track versions. The goal is simple: 👉 Move setup work into the background 👉 Let developers focus on building features 🚧 Still improving: I’m actively refining the logic, fixing edge cases, and expanding library support. If you try it out and something feels off or you want support for a specific library, I’d really appreciate the feedback.

Android Dev Series – Day 1: Why You Should Stop Writing Everything in Activities When I started Android development, I used to write everything inside Activities. API calls? Activity. Business logic? Activity. UI updates? Activity. It worked… until it didn’t. As apps grow, this approach leads to: - Hard-to-debug code - Massive classes - Difficult testing - Poor scalability ✔ So what’s the better approach? → MVVM (Model-View-ViewModel) Here’s the idea: => Activity/Fragment (View) Handles only UI (what user sees) => ViewModel Handles business logic and state => Repository Handles data (API, database, etc.) ----- Why this matters ----- When you separate concerns: ✔ Your code becomes cleaner ✔ Bugs are easier to track ✔ Features become easier to add ✔ You can reuse logic ✔ Testing becomes much simpler 🧠 Real Example Instead of doing this in Activity: val response = api.getData() textView.text = response.data Do this: => ViewModel handles API call => Activity observes the result Now your UI doesn’t care how data comes it just displays it. 🧠 Golden Rule If your Activity is doing too much… it’s doing it wrong. --- In this series, I’ll cover: ➤ Clean architecture ➤ Kotlin best practices ➤ Performance optimization ➤ Debugging crashes like a pro ➤ Modern Android tools (Flow, DI, etc.) #AndroidDevelopment #Kotlin #CleanCode #MVVM #MobileDevelopment

🔥 Big News for Android Developers: Room 3.0 has Arrived! 🔥 If you build on Android, you know Room. It's been our go-to persistence library for years. But the landscape is shifting, and Room just took a massive leap forward. I’ve been diving into the documentation for the new Room 3.0 (currently in 3.0.0-alpha01), and this isn't just a minor version bump—it's a foundational rewrite. Here are the game-changing shifts every developer needs to know: 🌍 1. Kotlin Multiplatform (KMP) Support This is the headliner. Room is no longer bound to Android! You can now write your persistence logic once and share it across Android, iOS, JVM (Desktop), Web, and WASM. This is a huge win for code-sharing and development efficiency. 🚫 2. Goodbye KAPT & Reflection (KSP Only!) Room 3.0 is a modern, Kotlin-first library. It has dropped support for KAPT and Java AP. You must use KSP. This change, combined with the removal of reflection, leads to faster build times and a significantly more optimized runtime experience. 📦 3. Out-of-the-Box Modern Types Less boilerplate, more productivity. Room now provides built-in support for: Kotlin Collections (List, Map, etc.) Kotlin Serialization (@Serializable objects) Modern java.time APIs (LocalDateTime, Instant) ⚡ 4. Mandatory Coroutines The days of blocking database calls are gone. All DAO operations are now non-blocking by default. You must use suspend functions or reactive types like Flow. 🛠️ Important Note: New Namespace! To prevent major migration conflicts, Room 3.0 uses the new maven group androidx.room3 and the package name androidx.room3.*. Keep this in mind when updating dependencies! Check out my summary graphic below for a visual breakdown of the key changes. 👇 Have you tried the Room 3.0 alpha yet? What feature are you most excited about?

𝗧𝗵𝗲 𝘀𝗶𝘁𝘂𝗮𝘁𝗶𝗼𝗻 Our app was stuck on React Native 0.66.4 — 17 versions behind the latest (0.83.1).

𝗪𝗵𝗮𝘁 𝗮𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝘄𝗼𝗿𝗸𝗲𝗱 Created a fresh React Native 0.83.1 project from scratch Moved just the src/ folder (business logic + UI) into it Reinstalled and reconfigured dependencies cleanly Done. No Gradle nightmares. 𝗧𝗵𝗲 𝗿𝗲𝗮𝗹 𝗶𝗻𝘀𝗶𝗴𝗵𝘁 For large version jumps, you don't need an upgrade — you need a migration strategy. Your actual app lives in src/ — that's what matters The project scaffold is disposable — start it fresh Keep deps updated regularly to never land here again Android / Gradle is almost always the biggest blocker If you're stuck in upgrade hell right now — skip the pain. Start fresh, move your code. You'll be done before the incremental approach even compiles. 𝗛𝗮𝘃𝗲 𝘆𝗼𝘂 𝘁𝗿𝗶𝗲𝗱 𝗮 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁 𝗮𝗽𝗽𝗿𝗼𝗮𝗰𝗵?

Faster development + production-ready apps 🚀 Android development is evolving fast… The question is — are you evolving with it? 👀 #AndroidDevelopment #Kotlin #Jetpack #MVVM #Developers #Tech #MobileApps #Programming #AndroidDev

Android Development Evolution (2008 → Now) Android development hasn’t just changed in terms of language or UI—it has evolved into a complete shift in architecture, thinking, and development style. Let’s break down how Android has evolved over time 👇 1. Early Android Era (2008–2012) 👉 It all started with very basic Java-based development Activity + XML UI Manual UI handling using findViewById No fixed architecture Everything was tightly coupled 📌 Main Issues: Code became messy very quickly Hard to maintain Almost no reusability 2. Support Library & Fragment Era (2013–2016) 👉 Efforts began to improve UI structure Introduction of Fragments Support Libraries for better device compatibility Shift from ListView to RecyclerView 📌 What Changed: UI started becoming more modular 📌 Still Missing: No clear, standard architecture yet 3. MVP / MVVM Era (2016–2019) 👉 Architecture thinking entered Android development MVP (Model View Presenter) MVVM (Model View ViewModel) Introduction of DataBinding 📌 Big Change: 👉 Separation of business logic from UI 📌 Challenge: Too much boilerplate code 4. Jetpack Library Era (2018–2021) 👉 Google officially introduced modern Android development tools LiveData ViewModel Room Database Navigation Component WorkManager 📌 Result: 👉 A standard architecture foundation was established 5. Kotlin First Era (2017–Now) 👉 Major shift from Java to Kotlin Null safety Coroutines for async operations Extension functions 📌 Impact: 👉 Code became shorter, cleaner, and safer 6. Single Activity Architecture Era (2020–Now) 👉 App structure evolved significantly One main Activity as a container Multiple screens handled via Fragments or Compose 📌 Why It Matters: 👉 Navigation became more controlled and cleaner 7. Jetpack Compose Era (2021–Now) 🔥 The biggest shift in Android UI development XML replaced by Compose Declarative UI system State-driven UI updates 📌 Core Idea: 👉 Instead of manually updating UI, just update the state—UI updates automatically 📌 Final Thought 👉 Android development is no longer just about coding 👉 It’s about system thinking, architecture, and scalability If someone wants to learn Android today, focus on: Kotlin + Coroutines Jetpack Compose Navigation + State Management Clean Architecture basics #AndroidDevelopment #JetpackCompose #Kotlin #AndroidDev #CleanArchitecture #MobileDevelopment #BuildInPublic
