An APK file (Android Package Kit) is the file format used by the Android operating system for the distribution and installation of mobile apps and middleware. APK files are a type of archive file, specifically in zip format packages, based on the JAR file format, with .apk as the filename extension. An APK file contains all of a program’s code (such as .dex files), resources, assets, certificates, and manifest file. When you download an app from the Google Play Store, your phone is actually downloading and running an APK file in the background.
How to Install Custom APK Files on Android Devices
Installing APK files allows you to install apps on your Android device that are not available on the Google Play Store. This process is also known as sideloading. Here’s a detailed lesson on how to do it:
- Enable Installation from Unknown Sources:
- Before Android 8: Go to Settings > Security (or Settings > Lock screen and security). Toggle on “Unknown sources.”
- Android 8 and later: The permission is granted on a per-app basis. You’ll be prompted to allow your browser or file manager to install APKs the first time you attempt to do so.
- Download the APK File:
- Download the APK file you want to install. You can use your device’s browser or transfer the file from your computer via USB, email, or other methods.
- Find and Open the APK File:
- Use a file manager app to navigate to the APK file. If you downloaded it using your device’s browser, it should be in the Downloads folder.
- Install the APK File:
- Tap the APK file in the file manager. You’ll see a prompt asking if you want to install the app. Confirm by pressing “Install.”
- After installation, you can launch the app normally from your device’s app drawer.
- Manage Installed Apps:
- Installed APKs will act like any other installed app, and they will update through the Play Store if the app is also available there and the app’s developer used the same signing key.
Safety Precautions
- Only Download from Trusted Sources: To avoid malware, only download APK files from reputable websites or sources.
- Check Permissions: Be wary of apps that ask for permissions that seem unnecessary for their function.
- Keep Unknown Sources Disabled: Re-disable the permission to install from unknown sources after installing your APK to maintain device security.
