If the APK file is Split into App bundles, 'App Not Installed', is the error you will face if you try installing APK. Make sure the File is Not Split APK App Bundle. If it is a bundle then you need to install it using a Split Installer. Google introduced a new way to distribute Android apps called app bundles.

While the regular apps contain all necessary resources like screen size, manifest, XML, Config, and architecture in a single APK. The app bundles only include the components that your specific device needs, organized into split APKs. While app bundles help save storage space and data usage, they are not one-size-fits APK files.

The Android Apps Bundle (AAB) Files can come in a compressed format like XAPK, APKS, APKM, or AAB. You can use any of the following methods to install the App Bundles on Android.

Google Play Protect is Google's built-in malware protection for Android. It scans the installed apps or apps to be installed for any virus and if it finds any harmful code or nature, blocks the installation. The play protects not only works or apps installed from the play store but also for 3rd party apps.

So, if you face any install error it is better to disable play protect and give it a try.

Here look for Play Protect
Click on the Settings icon
Disable Play Protect.

4. Sign the Unsigned App

5. Reset All the App Preference

Go to Settings on your Android device.
Open Apps or Apps manager.
check for All Apps.
Tap on the menu icon.
Click on 'Reset App Preferences.'

Reset App preferences

6. Avoid Installation from SD Card

If the APK is downloaded or if you are trying to install it from an external mount than in many cases it would be not possible due to contamination of the file. The installer may not completely parse the package from mounted storage.

The best solution, in this case, is to download the APK onto your internal storage and try installing the App. Your mobiles package installer will accept the files without any errors.

7. Use an older version of the App

Any latest version of the App may not support your device due to system limitations. Just download any older version of the App. If this works then your device is not capable to read the latest APK.

8. Clear Data and Cache of Package Installer

Open setting on your Android device.
Look for the option called Apps or Manage appsand tap on it.
Check for the Package Installer App under system Apps
You will find two option of Clear data and Clear cache. (For Android Marshmallow 6.0 users check for option Storageto clear data and cache)
Clear the data and cache to solve the problem.

9. Allow Apps from Unknown Sources

This is the most common issue which could cause the error on mobile or tablet.

Go to Settings → Security → Unknown Sources. Enable Unknown Sources. And then try installing App.

10. For Root Devices

If you have a rooted phone then the success rate increases manifolds.

Download and open any root explorer app on your rooted device.
Copy the Apk then go to system >app and grant permissions to the app.
You will see the App installed on your device.

Using Lucky Patcher

Download, install and open Lucky Patcher (Google Search to Download File)
Tap the option Toolbox
Click Patch to android
Check "Signature Verification status always true" and "Disable apk Signature Verification" and Apply.
Reboot your device if not automatically rebooted.

10. Clear Storage/Set Path

Clear some storage space on the device. Make sure SD Card has properly mounted if the file in located in SD Card.

I also recommend downloading the file in internal storage as downloading some types of APK files in external storage may sometimes cause issues due to improper read by package installer of Android OS.

Download the file from any other source in case the file itself is corrupted.

11. Other Miscellaneous Fixes

Delete .android_secure/smdl2tmpl.asec file from your SD Card.
Reboot the phone and even remove the battery if possible.
Uninstall all previous versions of the app or apps with the same resemblance currently installed on your device.
Remove the SD card and also do not connect your device to a PC while you install the apk.
Free up some space, uninstall unnecessary apps.
