By name: aosp-appendices description: | AOSP Internals — Appendices. Use when looking up a key file path (per-chapter table of the most important AOSP source files: build, init, kernel, HAL, framework services, system apps, infrastructure) or the meaning of an AOSP-specific acronym/term (Treble, VINTF, GKI, APEX, AIDL, HIDL, etc.), why Kotlin is absent from the public API, or what changed from Android 16 to Android 17. Reference material — load when you need a concrete path, a definition, or a changelog rather than narrative explanation. metadata: author: 'utzcoz' version: '2026.06.24' last-updated: '2026-06-24'
