Documentation

Public documentation for the on-device Android/Java IDE framework. Start with the architecture overview and follow the links into each subsystem.

• architecture.md — the project model, the two-level graph, the build-system abstraction, the concurrency model, and how extension points fit together.
• modules.md — the module map: every module, its package(s), and its responsibility, with the acyclic dependency direction.
• extension-points.md — the extension-point registry and every published extension point (module types, build systems, language backends, indexing, analysis, icons, templates, block mappings), plus the language-backend SPI.
• language-support.md — the backend-neutral DOM, code completion, the Java/XML/ Kotlin backends, indexing, analysis/diagnostics/quick-fixes, and block editing.
• kotlin-completion.md — how on-device Kotlin completion works: parse-only PSI, the framework's own symbols/inference, and classpath metadata decoding.
• block-editing.md — how the projectional (block) editor projects the shared DOM and round-trips block edits back to byte-for-byte source.
• build-system.md — the BuildSystem SPI, the incremental task engine, the native Java and Android pipelines, and the Gradle compatibility layer.
