Leveraging MCP Servers to Supercharge My Android Development Routine
Building A Local-First AI Memory Agent In Rust
My Android Release Checklist: Zero Bad Releases in 2 Years
I explain how I integrate a local MCP server into my Android workflow for instant code suggestions, automated test generation, and seamless CI/CD triggers, showing concrete Kotlin examples and performance gains.
How RustMarrow stores personal work context locally with SQLite, provider pullers, Obsidian mirroring, Claude queries, and JSON backup or restore.
A detailed, battle-tested checklist for solo Android developers to ensure stable, secure, and high-performance releases. Covers automated testing, CI/CD, performance monitoring, and final sanity checks.
This post shares 7 critical Room Database practices I've refined over 13 years of QA and building 22+ apps at SudarshanTechLabs. Focused on avoiding crashes, data loss, and performance pitfalls in production.
Amazon's Fire OS shares Android's codebase but diverges in ways that will surprise you. These are the specific behavioral differences — background restrictions, JavaScript timers, WebView versions, permission models — that break apps built for Android and deployed on Fire OS devices.
Monetizing with in-app purchases requires more than integrating the Play Billing Library. Here's how to handle purchase flows, verify purchases securely, restore purchases, and avoid the common mistakes that cause rejected apps and failed payments.
Learn how to use Android Keystore to protect API keys, tokens, and passwords in your Kotlin apps, with step‑by‑step code, best‑practice patterns, and common pitfalls to avoid.
Loading a thousand-item list all at once is how apps run out of memory and feel sluggish. Paging 3 loads data in chunks as the user scrolls. Here's how it fits together with Compose, Room, and a network source.
Material You lets your app adopt colors from the user's wallpaper while still keeping a brand identity. Here's how dynamic color works in Compose, how to support it without losing your brand, and the dark-theme details that matter.
Jetpack Glance lets you build home-screen widgets with a Compose-like API instead of clunky RemoteViews. Here's how it works, the constraints that make widgets different from app UI, and how to keep them updated efficiently.
Accessibility isn't a feature you bolt on at the end — it's a set of small habits during development. Here's how I make Compose apps work with TalkBack, large fonts, and switch access without much extra effort.
Ktor is a clean, coroutine-native HTTP client that shines especially in Kotlin Multiplatform projects. Here's how I set it up for Android — serialization, auth, retries, and error handling — and when I'd still pick Retrofit.
When Row, Column, and Box can't express your design, Compose's Layout composable and custom modifiers let you measure and place children yourself. Here's how the measure-and-place model works and when to reach for it.
Getting a build into testers' hands shouldn't require the Play Store review queue. Here's how I use Firebase App Distribution for fast beta cycles, how it compares to Play's internal testing, and when to use each.
KMP lets you share business logic between Android and iOS while keeping native UI on each. Here's what's actually worth sharing, what to leave native, and the realistic trade-offs from shipping it.
Root and tamper detection raises the cost of attacking your app, but it's a deterrent, not a wall. Here's a realistic look at what to check, how to respond proportionally, and why Play Integrity beats DIY checks.
Any API key you ship in an APK can be extracted — full stop. Here's how I actually handle keys in Android: which ones can live in the app, which must go behind a backend, and how to keep them out of git either way.
R8's obfuscation won't stop a determined reverse engineer, but it removes the easy wins and raises the cost of attacking your app. Here's what it actually protects, its limits, and how to configure it without breaking your build.
Certificate pinning hardens your app against man-in-the-middle attacks, but done wrong it can brick your app on a cert rotation. Here's when it's worth it, how to implement it safely, and the backup-pin discipline that prevents outages.
SharedPreferences and DataStore are where small but sensitive values quietly accumulate. Here's how I keep that local storage secure — what to encrypt, what to keep in the Keystore, and what not to store at all.
