If you've ever wanted to try an app not available in the default app store, you’ve probably encountered APK files. In this guide, you’ll learn exactly how to install APK on Android—whether it's on an Android phone, Android TV, or even an older version of Android—with clear installation steps and safety tips.
APK stands for Android Package Kit, a type of file used for distributing and installing apps on Android devices. Think of it as a zip file for apps, used by the package installer on your device.
When using the app store, you don’t see this file—it's handled in the background. But when sideloading, you work directly with the downloaded APK file using a file manager app or browser.
There are various reasons you might want to do this instead of using the Google Play Store:
The app is not available on the default app store.
You want an older version of an Android app.
You're testing a beta release.
You're using a device like Android TV that limits app availability.
Enable APK installations by modifying settings:
Go to Settings > Security.
Turn on Unknown Sources to allow non-Play Store installs.
Android uses a more secure, per-app permission system known as Install unknown apps, which limits access for security purposes.
Attempt to open the downloaded APK file using your web browser or file manager.
Grant that specific app permission to install APKs.
Use your web browser or transfer it from your PC via a USB cable.
Make sure it’s a valid APK installer file.
If prompted, allow the necessary app permission for the APK installer or package installer.
Open your file manager app (like ES File Explorer).
Navigate to the downloaded APK file.
Tap the file to begin the installation.
Confirm any app permission requests.
Click Install.
Wait for the APK to install, then tap Open or Done.
This is often the easiest way to sideload an APK onto your device.
