APK is a term that’s commonly used among Android users, but not many people necessarily understand what it stands for or what it represents. If you’re new to the world of Android or simply curious about this term, here’s a quick breakdown of what APK means and how it works.

What is an APK file?

APK stands for Android Package Kit. It’s the package file format used by the Android operating system for the distribution and installation of mobile apps. An APK file contains all of the elements that an app needs in order to be installed on an Android device, such as its code, resources, and manifest file.

What’s included in an APK file? What’s not included in an APK file?
App code User data
App resources (images, audio files, etc.) Device-specific configuration
Manifest file App updates or patches

How do you install an APK file?

Typically, Android devices are set up so that you can only download and install apps from the Google Play Store. However, it is possible to install apps from other sources, such as third-party app stores or directly from a website. To do this, you will need to enable installation from unknown sources in your device’s settings.

To install an APK file, you will need to download the file onto your device, either through a browser or via a file manager app. Once the file is downloaded, you can open it to begin the installation process. You may need to grant permissions for the app to access certain features on your device, such as your camera or microphone.

What are the risks of installing an APK file?

Since APK files can be downloaded from sources other than the Google Play Store, there is a greater risk of installing malware or other malicious software onto your device. It’s important to be cautious when downloading and installing APK files, and to only download files from trusted sources.

  • Make sure you trust the source of the APK file before downloading.
  • Use a reputable antivirus app to scan the file before installation.
  • Keep your device’s security settings up to date to help protect against malware.

What’s the difference between an APK file and an app bundle?

Recently, Google introduced a new distribution format called the Android App Bundle, which is designed to make app downloads more efficient and smaller in size. An app bundle contains all of the necessary elements for an app to be installed, but it delivers only the specific parts that a user’s device needs in order to run the app. This can help reduce the size of app downloads by up to 50%.

While APK files are still in use today, Google has recommended that developers switch over to using app bundles instead due to their efficiency and smaller size.


APK files are an essential part of the Android ecosystem, allowing developers to distribute and install their apps onto devices around the world. While installing APK files does come with certain risks, with proper precautions and common sense, you can still enjoy the benefits of installing apps from outside of the Google Play Store.
