What Skills Are in Claude Code Once you’ve used Claude Code for a while you’ll notice you repeat the same prompts. “Create a new feature screen with a ViewModel and UiState.” “Add a Room entity and DAO for this model.” “Write a Hilt module that provides this repository.” These are perfect candidates for skills — […]
Claude Code hooks let you run your own shell commands automatically at specific points in Claude Code’s lifecycle — for example, after it edits a file or finishes a command. Imagine every Kotlin file Claude touches getting formatted and linted on the spot, or your test suite kicking off the moment a test file changes.
Automating Android Root Cause Discovery with AI: Crashlytics, MCP, and Claude 4.8 Every Android app that ships crashes. Users hit unexpected states, device configurations trigger edge cases, and third-party libraries fail in mysterious ways. The traditional approach to bug fixing is manual: you read the stack trace, search for the failing line, mentally reconstruct the
What Is Android Credential Manager? Android Credential Manager is the new unified authentication framework that replaces the aging SmartLock and Autofill APIs. If you’ve been relying on those legacy systems, now’s the time to migrate. Credential Manager gives your users a modern, secure way to authenticate — and it’s simpler for you to implement than
What Is MediaPipe LLM Inference? If you’re building an Android app that needs to run large language models (LLMs) on-device, MediaPipe LLM Inference API is one of the most accessible ways to get there. It handles model loading, quantisation, and hardware acceleration so you can focus on the experience — no cloud dependency, no server
What Is the Predictive Back Gesture? Android 13 introduced the predictive back gesture — a system-wide feature that lets users preview their navigation destination by long-pressing the back button before fully committing to the action. It’s a powerful UX improvement that gives users confidence in their navigation choices, but it requires your app to handle
The Stack Trace Triage Problem Every app that ships crashes. Users hit unexpected states, device configurations trigger edge cases, third-party libraries fail in mysterious ways. When a crash report lands in Firebase Crashlytics, you’re looking at a stack trace, maybe some breadcrumbs or custom logs, and you need to decide: Is this a high-priority bug?
Why Your App Feels Slow on First Launch You’ve optimized your layouts, trimmed your dependency graph, and profiled your Compose recompositions. Yet users still report that your app feels sluggish the first time they open it after install or update. The culprit is usually JIT compilation — the Android Runtime compiles your app’s bytecode to
From Shared Logic to Shared UI If you’ve been following the Kotlin Multiplatform story, you’ve probably already shared networking with Ktor in a KMP shared module and persistence with SQLDelight across platforms. The next logical question is: can you share the UI too? With Compose Multiplatform, the answer in 2026 is a confident yes. JetBrains’
Why On-Device AI Matters for Android Developers Every AI feature you ship today probably depends on a network call. The user types something, your app hits an API, waits for a response, and displays the result. It works, but it comes with latency, server costs, and the uncomfortable fact that your app is useless without
The Gap That Claude Code Fills in Code Review Code review is one of the most valuable things a team does — and one of the most time-consuming. Reviewers catch real bugs, but they also spend energy on things that could be automated: spotting forgotten null checks, flagging coroutine scope misuse, noticing that a ViewModel
What Is the WallpaperColors API? Android 8.1 (API 27) introduced the WallpaperColors API, and it remains one of the most underrated tools for building personalized Android experiences. It lets you extract the dominant, secondary, and tertiary colors from your user’s system wallpaper and apply them to your app’s theme in real time. On Android 12+
Why Android Keyboard Animation Matters When your app shows a text input and the soft keyboard slides up, that moment sets the tone for user experience. A jarring jump or a laggy animation feels cheap. A smooth, synchronized transition where your content slides up in perfect sync with the IME (Input Method Editor) feels polished
What Is the Choreographer API? The Choreographer API is Android’s internal frame timing system — the heartbeat of smooth animation. Every frame your app draws, the Choreographer orchestrates the timing. It synchronizes with the device’s VSYNC signal (the vertical refresh of your screen), and it exposes a callback mechanism so you can hook into that
