The phrase describes the action of acquiring the installation file, in APK format, for the fourth installment of a particular video game. This typically involves obtaining the file from a website or app store for use on an Android operating system device. An example would be a user searching online and locating a website offering this file for direct device installation.
The significance stems from the desire to access and play the game on Android devices. Benefits could include portability and accessibility, allowing play on smartphones or tablets.
