jetpack-compose

adaptive

Instructions to make or update an app's UI so that it adapts to different Android devices including phones, tablets, foldables, laptops, desktop, TV, Auto and XR.

It includes how to handle different window sizes, pointing devices (such as mouse) and text entry devices (such as keyboard) using the Compose MediaQuery API. It also covers multi-pane layouts using Navigation3 Scenes, adaptive UI components (such as buttons) with varying target sizes, and adaptive layouts (including navigation areas - nav rails and nav bars) using the Compose Grid and FlexBox APIs.

migrate-xml-views-to-jetpack-compose

Provides a structured workflow for migrating an Android XML View to Jetpack Compose.

This skill details the step-by-step process, from planning and dependency setup, to theming and layout migration, validation and XML cleanup. Use this skill when you need to migrate an XML View to Jetpack Compose in an Android project. It solves the problem of converting the UI of a legacy XML View into modern, declarative Compose components while maintaining interoperability.

styles

Use this skill to integrate the Jetpack Compose Styles API into an Android project.

This skill guides you through upgrading dependencies, setting up component themes, making custom components styleable, and migrating existing layout properties to use unified styles. Migrate custom design system components, replace hard coded parameters with Style attributes, and use Modifier.styleable for interaction states.

media

media3-cast-integration

Implements Google Cast support in Android apps using Jetpack Media3.

Handles adding build dependencies, updating manifest, configuring OptionsProvider, and managing CastPlayer or RemoteCastPlayer for playback in both Compose and View-based UIs. Use when adding Cast functionality or migrating from legacy Cast SDK to Media3 Cast.

Learn how to install and migrate to Jetpack Navigation 3, and how to implement features and patterns such as deep links, multiple backstacks, scenes (dialogs, bottom sheets, list-detail, two-pane, supporting pane), conditional navigation (such as logged-in navigation versus anonymous), returning results from flows, integration with Hilt, ViewModel, Kotlin, and view interoperability.

Intercept back gestures and run Predictive Back animations using the NavigationEvent (androidx.navigationevent) library in Compose Android.

Handles Activity setup, parent-child dispatcher scoping in ViewPagers or tabs, Compose NavigationBackHandler, and migration from legacy BackHandler on SDK 36+.

performance

r8-analyzer

Analyzes Android build files and R8 keep rules to identify redundancies, broad package-wide rules, and rules that subsume library consumer keep rules.

Use when developers want to optimize their app's size, remove redundant or overly broad keep rules, or troubleshoot Proguard configurations.

play

engage-sdk-integration

Helps developers integrate, debug, and resolve Play Engage SDK implementation issues.

Use when adding Engage SDK support, generating publishing code, mapping data classes to entities, or fixing SDK-related errors.

play-billing-library-version-upgrade

Use this skill when upgrading or migrating an Android project from any legacy Google Play Billing Library (PBL) version to the latest stable version of PBL.

play-policy-insights

Automated auditor designed to verify Android applications against Google Play Policy domains.

It cross-references static code analysis with Play Store declarations to generate deterministic compliance reports, identifying undeclared data collection, architectural risks, and missing disclosures across Permissions and APIs Hygiene, User Account and Identity, and Data Safety and Privacy domains.

profilers

android-profiler

Manages Android performance profiling and debugging.

Triggers when the user asks to record or analyze Android performance data, such as system traces, heap dumps, method recordings, callstack samples, memory allocations, or investigate bottlenecks, jank, memory leaks, and app startup issues on Android, or when the user asks to write, debug, or execute ad-hoc SQL queries.
