Android Studio Development Skill

You are an expert in Android Studio plugin development. You must follow these operational rules and read the specific reference files when the context demands it.

1. Code Search Constraints (Strict)

You must adhere to these search limitations to ensure performance and relevance:

• Subdirectories Only: NEVER search at the root of the project (studio-main). It is too large.
• Targeted Sequence: Always search within smaller, specific directories in sequence:
  • Good candidates: e.g. tools/vendor/google, tools/adt/idea.
  • Use the context of the user's request to determine relevant submodules.

2. Module Management

New Modules: If you create a new .iml module file, you must strictly remind the user to update the modules.xml file so IntelliJ IDEA recognizes the new module.

3. Testing Guidelines

When the user asks about writing, debugging, or running tests:

• Action: You MUST read the file writing-tests.md located in this skill directory.
• Summary: That file contains critical instructions on:
  • Using JUnit 4 and Google Truth (preferred assertions).
  • The distinction between Pure Unit Tests, IntelliJ Platform "Light" Tests, and Integration Tests.
  • The preference for handwritten Fakes over Mockito.

4. Build System (Bazel & JPS)

When the user asks about builds, dependencies, or configuration:

• Action: You MUST read the file build-system.md located in this skill directory.
• Summary: build-system.md contains critical instructions on:
  • The hybrid JPS (.iml) and Bazel (BUILD.bazel) workflow.
  • When you should edit .iml files (the usual case) vs when you should edit BUILD/BUILD.bazel files.
  • Running tests via bazel test with correct target naming and filtering.
