androidosBuildVERSION

androidosBuildVERSION is a label sometimes seen in Android build processes to denote the version string of the Android operating system being built. It is not an official Android API name, but rather a generic placeholder or variable that can appear in build scripts, manifests, or documentation within AOSP-inspired workflows or vendor customizations. The aim is to carry the OS version identity through the build pipeline so that artifacts, logs, and update mechanisms can reference the exact release.

In typical practice, Android version identity is multi-part. A user-visible version string may reflect the release (for example, a major release such as 13 or 13.0.0), combined with a build or incremental tag. Build systems also expose incremental identifiers, often called a build ID or patch level. At runtime, the Android framework presents properties such as Build.VERSION.RELEASE and ro.build.version.incremental that correspond to the deployed OS, while ro.build.display.id may carry a device- and build-specific label.

Creation and usage: during the build, a version string may be assembled from release data, API level, and incremental components and assigned to properties embedded in the system image as a version token, including forms analogous to androidosBuildVERSION. This token can assist update services, recovery tools, and diagnostics in determining compatibility or selecting appropriate packages.

Notes and scope: because the term is not standardized, its exact syntax and location vary by project or vendor. The authoritative user-visible version is typically provided by ro.build.version.release or the Build.VERSION class at runtime, rather than a single internal token.
