i was wondering if an android user can help me out just switched from iPhone never used an android at all how do you go about downloading onto it threw computer threw the phone teach me please lol
Android apps are in APK format (which is going to be replaced by AAB format in the future but that isn't something you should be concerned about right now)
APK is a package file.
It decrypts & installs on your android automatically by device installer when you download & click to install .apk file.
There is another file that is called OBB file. It's usage has decreased over the year but let me tell you what it is.
OBBs are big ass data file for android apps. It can be 1GB~3GB+. If you devcrypt those files you'll find necessary data & assets if its a game.
You maybe confused how APK & OBB work. Well, if you ever download GTA SA on your android phone, you'll find 2.5 GB OBB file & a 30MB APK.
You have to place that OBB file in android folder of your internal storage & install that APK of 30MB which is like the launcher. The APK & OBB there, are interconnected with XMLs inside. Once you install the APK, if you placed the OBB properly, it will detect that OBB & open up your game.
But nowadays APKs are created in such a way, you don't need a separate OBB file anymore.
