What is APK File and How it works?

APK is the acronym for Android Package Kit (or Android Application Package). It is the file format Android uses to distribute and download apps. Your device needs an APK to install an app correctly, which contains all the necessary components.

APK stands for archive file. It contains multiple files and metadata. You may be familiar with other kinds of archive files, such as ZIP and RAR.

The purpose of an archive file (such as the ZIP format) is to combine multiple files into one file. Accessing them becomes easier or their size decreases.The process of archiving and distributing software creates software packages.

APK files are actually variations of JAR files. This is because a lot of Android is written in Java. It is possible to download APKs as ZIP files, but they must contain additional information to function properly.

All APKs can be considered ZIPs. However, not all ZIPs can be APKs. You can open an APK file to see what it contains if you are curious.

Why would I install APK files manually?

In most cases, Android can be installed through Google Play. Manually installing APKs has many benefits.

One of the greatest benefits is being able to access the latest versions of apps in advance. It can take up to a week for your device (or more) to receive the latest version of a Google app (like Calendar). The APK can be installed yourself so you can get it as quickly as possible.

Installing APKs from outside of Google Play gives you access to apps you are unable to download from the Google Play store. You might want to check out an app that’s not on Google Play or check out an app that a friend is developing.

It is dangerous to download APK files from unknown websites, just as it is to download desktop software. In Google Play, you are protected against dangerous apps, but when you install APKs on your own, you have no such protection.
