Shape Android build logic with Gradle, version catalogs, plugins, convention patterns, and toolchain compatibility.
Implement Clerk authentication for native Android apps using Kotlin and Jetpack Compose with clerk-android source-guided patterns. Use for prebuilt AuthView/UserButton or custom API-driven auth flows. Do not use for Expo or React Native projects.
Provides knowledge and workflows to implement Android's Restore Credentials feature using the androidx.credentials library. Use this skill to create, sign in with, and delete restore keys, enabling silent user sign-in on new devices after a restore. It covers version compatibility, dependencies, server-side prerequisites, and the complete client-side implementation for creating, retrieving, and clearing restore keys.
Audits Android codebases for ANR risks and diagnoses ANR stack dumps. Use this skill when scanning Android code for ANR risks or triaging ANR stack dumps. Don't use for non-ANR crashes, dropped frames, general CPU profiling, or Perfetto system traces.
Analyzes Android codebases to implement ML Kit GenAI Prompt API. Use this skill to send natural language requests on-device to Gemini Nano, use structured output with Prompt API, implement prefix caching, optimize the current prompt, or apply best practices."
Configures and implements LiteRT (.tflite) on-device inference on Android in Kotlin using the CompiledModel API on CPU and GPU. Use this skill for any Android LiteRT or .tflite task, including Gradle setup, image classification or vision/audio/embedding helpers, TensorBuffer reuse, CPU memory optimization, Bitmap preprocessing, AndroidViewModel GPU-to-CPU fallback with warm-up on a single-thread dispatcher, LiteRT in Google Play services (play-services-litert), migrating from legacy org.tensorflow.lite.Interpreter, GpuDelegate, or play-services-tflite, and latency benchmarking. Don't use for running generative text LLMs with .litertlm files or for Python model conversion.
Diagnose and optimize Android Jetpack Compose UI code. Use this skill when analyzing performance bottlenecks of existing code to minimize recomposition overhead and prevent dropped frames and UI lag.
Use this skill to create home screen widgets using Jetpack Glance Canonical Layouts from the Android Platform Samples project, or when asked to implement standard widget layout patterns (including Check List, Image Grid, Snap Scrolling, and Standard Toolbar).
Create, migrate, update, and verify Wear OS widgets using Glance Wear and Remote Compose in an Android project. Use this skill when implementing GlanceWearWidget, GlanceWearWidgetService, WearWidgetDocument, Remote Compose UI primitives (RemoteColumn, RemoteRow, RemoteBox, RemoteText, RemoteImage, RemoteButton), local state with rememberMutableRemoteInt and valueChange, click actions with pendingIntentAction, widget provider XML containers (SMALL and LARGE), rectangular widget picker PNG previews, or migrating legacy ProtoLayout TileService tiles to Wear OS widgets. Don't use for mobile home screen AppWidgetProvider or GlanceAppWidget implementations, watch face complications, or full-screen Wear OS activities.
Upgrades an Android app (Java or Kotlin) that uses the Navigation SDK for Android (com.google.android.libraries.navigation) from 7.x to 8.0. Covers the AGP 9.0.1 / Gradle 9.1.0 toolchain floor, targetSdk 37 and the Play Location Purpose Declaration, removed transitive dependencies (kotlin-reflect, Glide), androidx.car.app 1.3.0, and the 8.0 API changes: removed DisplayOptions.showTrafficLights / showStopSigns and onGpsAvailabilityUpdate, new RouteStatus.ROUTING_TIMEOUT, terrain map type during navigation, and deprecations of ListenableResultFuture, SupportNavigationFragment, setAudioGuidance, FollowMyLocationOptions, and NavigationTransactionRecorder Waypoint overloads. Use when upgrading NavSDK to 8.0, fixing a build that broke after the bump, or auditing what 8.0 changes for an app. Don't use for iOS.
Builds an Android app that runs an open text LLM on the device, on the CPU or the GPU, with the LiteRT-LM Kotlin API (com.google.ai.edge.litertlm:litertlm-android). Use this skill when creating a chat, summarization, or extraction feature with a .litertlm model from Hugging Face litert-community (Gemma, Qwen, Llama, Phi), including the Gradle dependency, the GPU manifest entries, getting the model file onto the device, Engine initialization off the main thread, a streamed multi-turn Conversation with sendMessageAsync, and the AndroidViewModel and Compose screen. Don't use for running .tflite vision, audio, or embedding models with the CompiledModel API, for image or audio input, tool calling, or NPU backends, or for converting models.
Guides the agent through enabling R8 in a Capacitor Android app so that it meets the Google Play DEX code optimization requirement (at least 25% obfuscation, optimization and shrinking from February 2027 for apps with more than 10 MB of DEX code). Covers `minifyEnabled true` with `proguard-android-optimize.txt` in `android/app/build.gradle`, the `-keep @interface com.getcapacitor.** { *; }` rule that prevents the startup crash in R8 full mode, per-plugin keep rules, resolving R8 'Missing class' build errors via `missing_rules.txt`, building a signed release APK with the debug keystore, and verifying with logcat, `mapping.txt` and the `r8.json` file inside the app bundle. Use when Play Console reports a DEX code optimization finding, when a Capacitor app crashes on startup after enabling `minifyEnabled`, or when R8 fails the release build. Do not use for iOS, resource shrinking, Capacitor plugin projects, Capacitor version upgrades, or non-Capacitor mobile frameworks.
