This identifier refers to a specific build of the YouTube application for Android operating systems. It delineates the package name (com.google.android.youtube), the file type (APK, or Android Package Kit), a particular iteration of the software (version 19.45.38), and the target processor architecture (arm64-v8a). A similar identifier might be “com.example.app version 2.0 x86,” indicating a different application, version, and processor support.
The specification provides crucial information for developers, distributors, and users. Knowing the version allows for verifying updates, identifying compatibility issues, and ensuring the correct software is installed for a given device’s hardware. It also plays a vital role in security audits and vulnerability assessments, as specific versions may be known to contain certain exploits. Historically, such detailed identification has been essential for managing the fragmented Android ecosystem and addressing device-specific software challenges.
