How to Fix 1 APK Not Found Error on Android
If you are an Android user, you might have encountered the frustrating error message "1 APK not found" when trying to install an app from a .apk file. This error means that your device cannot find or recognize the app package file that you are trying to install. In this article, we will explain what an APK file is, why you need it, what causes the error, and how to fix it with seven easy methods.
What is an APK File and Why Do You Need It?
APK File Definition and Format
An APK file stands for Android Package Kit. It is a file format used by the Android operating system for distributing and installing mobile applications, games, and middleware. An APK file contains all of the app's code, resources, assets, certificates, and manifest file. It is similar to other software packages such as .exe files in Windows or .app files in macOS. An APK file usually has a .apk extension, but it can also have other extensions such as .apks, .aab, .xapk, .apkm, or .akp.

APK File Benefits and Uses
An APK file has many benefits and uses for Android users. Some of them are:
You can install apps that are not available on Google Play Store or your region.
You can install older versions of apps that are no longer supported or updated by the developers.
You can install modified or customized versions of apps that have extra features or functions.
You can backup or restore your apps and data without using Google services.
You can test your own apps before publishing them on Google Play Store.
What Causes 1 APK Not Found Error on Android?
Common Reasons for the Error
There are many possible reasons why you might get the "1 APK not found" error on your Android device. Some of the common ones are:
Your APK file is corrupted, incomplete, or damaged.
Your APK file is not compatible with your device's OS version, hardware specifications, or screen resolution.
Your APK file is not signed by the developer or has been tampered with by a third-party source.
Your device does not have enough storage space to install the app.
Your device does not have the proper permissions to install apps from unknown sources.
Your device has a security feature that blocks the installation of apps from untrusted sources.
How to Check if Your APK File is Valid and Compatible
Before you try to fix the error, you should first check if your APK file is valid and compatible with your device. Here are some steps you can follow:
Download your APK file from a reputable source such as Google Play Store, APKPure, or APKMirror. Avoid downloading from unknown or suspicious websites that may contain malware or viruses.
Check the file size and extension of your APK file. A normal APK file should have a .apk extension and a reasonable file size depending on the app. If your file has a different extension or a very small or large file size, it may be corrupted or fake.
<li Use an online tool such as APK Analyzer or APK Editor to inspect the contents of your APK file. You can see the app's name, version, package name, permissions, resources, assets, and code. You can also compare the APK file with the original one from Google Play Store or the developer's website. If you find any discrepancies or anomalies, your APK file may be invalid or incompatible.
How to Fix 1 APK Not Found Error on Android?
If you have verified that your APK file is valid and compatible, but you still get the error, you can try the following methods to fix it. Note that some of these methods may require you to have root access or a custom recovery on your device.
Method 1: Change App Codes or Sign the Unsigned App
One of the possible reasons for the error is that your APK file is not signed by the developer or has been modified by a third-party source. This can cause a mismatch between the app's codes and signatures, which prevents the installation. To fix this, you can either change the app's codes or sign the unsigned app using a tool such as APK Editor or ZipSigner. Here are the steps:
Download and install APK Editor or ZipSigner from Google Play Store or another trusted source.
Open the app and select your APK file from your device's storage.
If you are using APK Editor, tap on "Common Edit" and change the app's name, version, package name, or permissions as you wish. Then tap on "Save" and wait for the app to rebuild the APK file.
If you are using ZipSigner, tap on "Choose In/Out" and select your APK file as both input and output. Then tap on "Sign the File" and wait for the app to sign the APK file.
Once done, try to install the new APK file on your device and see if the error is gone.
Method 2: Reset App Permissions or Clear Package Installer's Data and Cache
Another possible reason for the error is that your device does not have the proper permissions to install apps from unknown sources. This can happen if you have denied or restricted the permission for some apps or system processes. To fix this, you can either reset the app permissions or clear the package installer's data and cache. Here are the steps:
Go to your device's Settings and tap on "Apps" or "Applications".
Find and tap on the app that you are trying to install from an APK file. It could be a file manager, a browser, or a downloader.
Tap on "Permissions" and make sure that all of the permissions are enabled for the app. If not, toggle them on.
Go back to the Apps list and find and tap on "Package Installer".
Tap on "Storage" and then tap on "Clear Data" and "Clear Cache".
Reboot your device and try to install the APK file again.
Method 3: Do Not Install from Untrusted Sources other than Google Play Store
A third possible reason for the error is that your device has a security feature that blocks the installation of apps from untrusted sources. This can happen if you have enabled Google Play Protect, which scans your device for harmful apps and warns you before installing them. To fix this, you can either disable Google Play Protect or only install apps from trusted sources such as Google Play Store or official developer websites. Here are the steps:
Go to your device's Settings and tap on "Google".
Tap on "Security" and then tap on "Google Play Protect".
Toggle off the option "Scan device for security threats".
Alternatively, you can also tap on the gear icon at the top right corner and toggle off the option "Improve harmful app detection".
If you want to keep Google Play Protect on, you can also whitelist your APK file by tapping on it and selecting "Install anyway (unsafe)".
However, it is recommended that you only install apps from trusted sources such as Google Play Store or official developer websites.
Method 4: Delete Unnecessary Applications and Files
A fourth possible reason for the error is that your device does not have enough storage space to install the app. This can happen if you have too many apps, files, photos, videos, or music on your device. To fix this, you can either delete some of the unnecessary applications and files or move them to an external storage device such as a SD card or a USB drive. Here are the steps:
