APK (Android Package File) is the file format used to distribute and install Android applications. It’s similar to an executable file on Windows or a .dmg file on macOS. APK files contain all the necessary files and code for an Android app to run.
OBB (Opaque Binary Blob) files, on the other hand, are used to store large amounts of data, such as game assets, graphics, and sound files. OBB files are often used in conjunction with APK files to provide a complete gaming experience.
While Call of Duty: Black Ops 2 was not officially released for Android, it’s technically possible to run the game on Android devices using APK and OBB files. However, this method is not supported by the game developers, and it may require some technical expertise to get the game up and running.
