What Exactly is an APK (Android Package Kit)?

The full form of APK is Android Package Kit. Android uses this file format to distribute and install applications not available on Google Play Store. This is a complete package which contains everything an app needs to run on an Android system.

Do you know about Zip files? API resembles them in many formats. Just as a Zip file stores data inside APKs, it also stores resources, images, and code required for the app to install and run inside a system.

When you download an app from the Google Play Store, your phone is actually downloading and installing an Android Package Kit file in the background automatically. You can download APK files easily from the website. APK is a package which contains everything so that you can install and use it to set up your application and run.

Imagine it is your birthday, and your friend gives you a beautifully wrapped gift box.

• The gift box is like the APK file.
• Inside the box, there might be different items:

1. A toy (the app’s main features)
2. Instructions on how to use it (the app code)
3. Stickers and decorations (images and icons)

When you receive the box, you unwrap it (install it on your phone), and now you can play with the toy and use everything inside.

If you get your gift from a trusted friend (Google Play Store), you feel safe and happy. But if a stranger hands you a gift box (an APK from an unknown website), you might wonder: “Is it safe? Is there something harmful inside?”

So, an APK is like a gift box which is a complete package with everything your app needs to work. Once you “unwrap” it on your Android device, the fun begins! You get a lot of cool features which you can use for different purposes.

Example of APK (Android Package Kit)

Suppose we have a Windows laptop where we want to install a simple program i,e. Photoshop or Chrome, then we usually download an .exe file which is the setup file.

• The .exe file contains everything needed to install the program on your computer.
• When you double-click it, it uncovers all the important files and installs them so you can start using the program.

The same happens on Android device when you download an APK file.

• An APK file is like the .exe file for your phone.
• It contains everything your app needs, including code, images, sounds, and other resources.
• When you tap to install it, Android unpacks it and sets up the app for you to use.

So, just like you need a setup file on Windows, you need an APK file on Android to install an app manually. The same process happens automatically when you install an app from the Play Store.

How Does an API File Work?

An Android Package Kit file is like a complete box filled with all necessary components of an app. All you need is install it on your local device and then your smartphone will unpack and assemble the app on your device. Its just that simple.

Suppose you are buying a new piece of furniture from IKEA such as a study chair. Now when you open the box you will get your chair in parts which you need to assemble. Now, use all the pieces, screws, and tools to set up the chair in place. You can use the user manual and follow the instructions to set up the chair.

Now, when it comes to APK it contains all your app needs i,e. Code, images, media, and other instructions to download the application and run it successfully on your device.

When you install the APK on your phone, your Android system acts as a person who is setting up the application using the manual. It arrange everything in place so that application can run easily on the system.

Why Do We Exactly Need APK Files?

We need APK files in our system so that we can download any application using the package. As soon as we download the APK on our device and then install it the app becomes ready to use. It can either be any application, a music app, gaming app, timer app, calendar, editor, etc.

If APK would not have been there every person would have to manage code files to build app on the phone. This might get complex for people having very little knowledge about code. APK tends to increase the accessibility of people by providing us an easy way to get our favorite app on our device.

APK vs App Bundle: Major Differences

Android Package Kit contains every resource important for an app to set up and run on the device, while the App bundle is a smaller and customised format tailored for a specific device.

What is APK?

When you order an APK, it is like getting one big, ready-made meal box, with everything inside already decided by the chef. Every APK has all the code, images, and resources bundled together.

It doesn’t matter if your phone needs some parts or not; you still get the full package. Simple and works on any Android device, but can be big in size.

What Is an App Bundle?

When you order a custom meal kit, it only includes what you need based on your diet, preferences, and portion size. An App Bundle is like that meal kit; it has all the possible parts, but when you download it, Google Play builds a custom APK just for your device.

This APK will include only the necessary code and resources. This makes the app smaller and faster to download, saving storage space and data.
