If you directly try to Install the APK you will see ‘App not Installed’ Error. In simple terms, APK is split in different APKs which include Base.APK, Config-Archi.APK and other Files which can only be installed using a 3rd party split installer. You need to use a split APK installer to install app bundles if you have downloaded multiple APK files. While the above links can be helpful if the APK files are compressed as a single AAB.

If it is a bundle then you need to install it using a Split Installer. Make sure the File is Not Split APK App Bundle.

If the APK file is Split into App bundles, ‘ App Not Installed‘, is the error you will face if you try installing APK. Uninstall the similar pre-installed app and install the modified App from APK Editor.
