From the author

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.

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides a systematic methodology for converting Android XML Views into declarative Jetpack Compose components. It emphasizes maintaining visual parity and functional integrity through a rigorous process that includes project analysis, dependency setup, theming alignment, and validation. The workflow is designed for incremental adoption, ensuring that legacy XML and new Compose code can coexist through interoperability APIs while preparing the codebase for a full transition to Compose.

What it does

  • Analyzes existing XML layouts and project infrastructure for migration readiness.
  • Guides the setup of Compose dependencies and compiler configurations.
  • Facilitates the migration of XML themes to Material 3 Compose theming.
  • Provides a structured approach to replacing XML View usages with Compose components.
  • Ensures visual parity through automated screenshot testing and Compose Previews.
  • Manages the safe removal of legacy XML files and associated resources.

When to use it

  • When modernizing an Android application's UI layer from XML to Jetpack Compose.
  • When you need to perform an incremental migration of specific UI components.
  • When you need to ensure visual consistency between legacy XML and new Compose code.
  • When integrating new Compose features into an existing View-based Android project.

Advantages

  • Reduces risk by following a validated, step-by-step migration methodology.
  • Maintains project stability through interoperability best practices.
  • Ensures visual fidelity using baseline screenshot comparisons.
  • Promotes clean code by systematically removing redundant legacy XML resources.

Usage examples

“Help me migrate my login_screen.xml to Jetpack Compose.”
The agent will initiate the 10-step workflow, starting with an analysis of the login_screen.xml structure and project dependencies to create a migration plan.
“How do I handle theming when moving from XML to Compose?”
The agent will guide you through mapping XML color attributes and styles to Material 3 semantic roles within a Compose MaterialTheme.

Documentation by Google LLC

This skill guides through the process of migrating an existing Android XML View to Jetpack Compose. It performs a stable, safe and visually consistent transition by following a structured, 10-step methodology. This skill migrates UI (XML to Jetpack Compose) only.

Objective

To systematically convert a single legacy XML layout into modern, declarative Jetpack Compose UI while maintaining pixel-perfect visual parity and functional integrity.

Summary of the 10-step migration process

  1. Identify the optimal XML candidate for migration

  2. Analyze the project and layout

  3. Create a plan

  4. Capture the XML View UI

  5. Set up Compose dependencies and compiler

  6. Set up Compose theming

  7. Migrate the XML layout to Compose

  8. Validate the migration

  9. Replace usages

  10. XML code removal

Detailed steps

Step 1: Identify the optimal XML candidate for migration

If the user has explicitly specified a target XML layout, proceed to Step 2. Otherwise, analyze the codebase to identify the best candidate for migration by following the logic in references/identify-optimal-xml-candidate.md.

Step 2: Analyze the project and layout

Analyze the identified XML View's structure, hierarchy, and implementation details. Use references/analysis-of-the-project-and-layout.md to guide your technical audit of the layout and surrounding project context.

Step 3: Create a plan

Using the outputs and analysis done in the Step 1 and 2, generate a step-by-step plan for the migration. If you support user interaction, present to the user and ask for approval before proceeding. If user interaction is not supported, proceed to Step 4 following the generated plan.

Step 4: Capture the XML View UI

IF you support user interaction, ask the user to upload a screenshot of the XML View UI or provide an absolute path to a file. Use this image as a visual reference for the layout migration in Step 7. ELSE IF you are able to run an Android emulator, locate an existing screenshot test for the XML candidate. If none exists, create one using the existing project testing framework. If no framework exists, use UI Automator or Espresso to create a screenshot test with minimum required setup. Run the test and take a baseline screenshot of the XML UI. ELSE proceed to Step 5.

Step 5: Set up Compose dependencies and compiler

Check build.gradle or libs.versions.toml for Compose dependencies and compiler setup. If missing, use Setup Compose Dependencies and Compiler. Run a sync to ensure dependencies resolve without errors.

Step 6: Set up Compose theming

If the project already has Compose theming set up, proceed to Step 7. If Compose theming is missing, initialize it. For Material-based projects, follow Material 3 migration guidelines. For custom design systems, apply expert judgment to migrate XML theming and match existing styles. Constraints: Do not migrate the entire theme. Implement only the minimum theming required for the specific XML candidate. Maintain original XML themes for interoperability. Maintain existing project code conventions, patterns, names and values.

Step 7: Migrate the XML View to Compose

Convert the XML candidate to Jetpack Compose code, referencing references/xml-layout-migration.md and the image from Step 4. You must include a Compose Preview for the newly created composable to facilitate visual verification.

Step 8: Replace usages

Replace the usages of the migrated XML layout to use the new Compose component.

Step 9: Validate the migration

Compare the baseline screenshot image from Step 4 with the rendered Compose Preview of the new composable. Ignore string content; focus on layout and styling. Iterate on the Compose code until visual parity is achieved. Once verified, write a Compose UI test for the new composable.

Step 10: XML code removal

Delete the migrated XML file and its associated legacy tests. Caution: Only remove code and resources that are not referenced by other parts of the project.
