Split APKs Installer (SAI) 4.2 Apk + Mod (Untouched) for android
SAI is an app for installing split APKs – apps that consist of multiple APKs. It has both rootless and rooted installation methods.
SAI is an open-source app, you can get the source code on its GitHub repo – github.com/Aefyr/SAI
Please note that SAI only installs user-provided files and is not responsible for those apps behavior.
Please also note, that some devices/ROMs aren’t supported by SAI, that has to do with bad Android API implementation in said ROMs and can’t be fixed on app side.
