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. There is no longer a proper “Open app” prompt after installing an app with rooted installer due to internal architecture changes. Optimized installation from zip archives. SAI no longer creates temp copies of all of the files in the archive, but reads them directly instead.
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.
