What problem does it solve? Public Android documentation often omits internal implementation details such as @hide APIs, default attribute values, and system service behavior, forcing developers to read the actual platform source code to answer technical questions. ## Core Features & Use Cases - Dual source tree access: Fetches AOSP framework internals from android.googlesource.com (Gitiles) and AndroidX/Jetpack libraries from GitHub raw URLs, with correct URL formats for each. - MCP tool integration: Prefers android-source-explorer MCP tools for class lookup, method reading, hierarchy inspection, and regex search when available, falling back to WebFetch and gh CLI otherwise. - Path inference and search strategy: Maps fully qualified class names to repository paths and provides directory listing via gh api when the exact path is unknown. - Use Case: You need the default value of a View attribute or the signature of a @hide method in ActivityManagerService. The skill infers the path under platform/frameworks/base and fetches the current source from Gitiles. ## Quick Start Fetch the current AOSP source for android.view.ViewGroup and show me its @hide methods.
