SAI (Split APKs Installer)

What is SAI?
SAI (Split APKs Installer) is an app that lets you install multiple APKs as if it was a single package. This is useful for installing apps that are distributed as App Bundles since Android provides no built-in way to install them from sources other than Google Play.
How to use SAI?
Click "Pick APKs" button and select base APK as well as additional configuration-specific APKs then click "Select" button to start installation process.
