This refers to a specific version of the Android Auto application, packaged in the Android Package Kit (APK) format. The version number, 13.5, indicates a particular release within the application’s development cycle. The APK file is used to distribute and install the application on Android devices. For example, a user seeking to manually install or update to this iteration of Android Auto might search for and download this file.
Such a file provides access to a particular iteration of the software, potentially offering new features, bug fixes, or performance improvements compared to earlier versions. Historically, APK files have been a common method for distributing Android applications outside of official channels like the Google Play Store. This allows users greater control over the software versions on their devices, but also carries the risk of installing potentially harmful or unstable software.
