This designation refers to a specific build of the YouTube application for Android devices. “com.google.android.youtube” is the application’s package name, uniquely identifying it within the Android operating system. “apk” signifies that it’s an Android Package file, the format used for distributing and installing apps. “version 19.44.39” is the application’s version number, indicating a particular release with a defined set of features and bug fixes. “arm64-v8a” specifies the Application Binary Interface (ABI) architecture, targeting devices with 64-bit ARM processors. This combination of elements precisely pinpoints a distinct iteration of the YouTube application tailored for compatible Android devices.
The specificity of this designation is crucial for several reasons. It allows users to install the correct version of the application for their device’s architecture, ensuring optimal performance and compatibility. Knowing the version number is important for identifying which features are available, understanding if security patches are up-to-date, and troubleshooting issues. Historically, APK files allowed users greater control over app installations, allowing sideloading (installing outside of the Google Play Store) to access older versions or versions not yet available in their region. This also gives users a detailed look into the build structure for the given application and helps developers troubleshoot device specific installations.
