Want to install APK files on your Android phone? This guide shows you how, step by step. It works on Samsung, Xiaomi, Pixel, OnePlus and every other Android device, and takes about two minutes.
An APK (Android Package) is the file format Android uses to install apps. Google Play installs APKs for you in the background. When you download an app from ApkSpark, you install the APK yourself — that is called sideloading.
Before you install APK files
Check three things first:
- Free space – the app needs room for the file and the installed app. Twice the APK size is a safe rule.
- Android version – each app page on ApkSpark shows the minimum Android version under App info.
- A trusted source – only download APKs from sources that show where the file comes from. Every download on ApkSpark is a direct file from the developer, GitHub, F-Droid or our own servers.
How to install APK on Android: 5 steps
Step 1: Download the APK
Open the app's page on ApkSpark and tap Download APK. The file downloads straight away — no timers or extra pages. When it finishes, your browser shows a notification.
Step 2: Open the downloaded file
Tap the notification, or open the Files / My Files app and go to Downloads. Tap the file that ends in .apk.
Step 3: Allow installs from your browser
The first time you install APK files, Android asks for permission. Tap Settings, turn on Allow from this source, then go back. You only need to do this once per browser.
On older phones (Android 7 and below) the setting is called Unknown sources under Settings → Security.
Step 4: Tap Install
Android shows the app name and asks if you want to install it. Tap Install and wait a few seconds.
Step 5: Open the app
Tap Open, or find the new icon in your app drawer. That's it — you're done.
How to update an app you installed from an APK
Apps installed from an APK don't always update automatically. To update, download the newer APK from the same page and install it over the old one. Your data stays in place.
Android only accepts the update if it is signed with the same key as the version you have. That is why ApkSpark checks the signing certificate of every upload and shows its fingerprint on the app page.
Is it safe to install APK files?
It is safe when the file comes from a trustworthy source. To stay safe:
- Download only from sites that show where each file comes from.
- Compare the SHA-256 checksum on the app page if you want to be certain the file wasn't changed.
- Read the permissions list before installing. A flashlight app doesn't need your contacts.
- Keep Google Play Protect turned on — it scans sideloaded apps too.

Common problems when you install APK files
"App not installed"
This usually means a version with a different signature is already on your phone. Uninstall the old version first (back up your data), then install again.
"There was a problem parsing the package"
The download didn't finish, or the app needs a newer Android version. Download the file again and check the minimum Android version on the app page.
"Install blocked"
Your phone or a parental-control setting blocks installs from unknown sources. Check Settings → Security or ask the device administrator.
