SAI exists because Android changed how apps are distributed. Google Play now ships most large apps as split bundles — a base package plus separate pieces for your screen density, CPU architecture and language — and Android's own installer will not accept those as a set of loose files. SAI does: point it at an XAPK, APKS or APKM archive, or at a folder of split APKs, and it installs them together the way Play would. It is open source, published on GitHub, and asks for nothing beyond storage access and the permission to install packages. On this site it is the tool that makes any split-bundle download usable.

FAQ
Is SAI open source?
Yes — SAI is free and open source (GPL). The full source code is on GitHub (github.com/Aefyr/SAI); we mirror the unmodified official release and publish its SHA-256 checksum.
Why do I need SAI at all?
Because a plain APK is only part of a modern large app. Google Play splits big apps into a base package plus device-specific pieces, and Android's built-in installer will only take one file at a time. If a download here is marked XAPK rather than APK, tapping it without SAI produces an error rather than an install.
Should I trust SAI with install permission?
SAI is open source and its releases are published on GitHub by the developer, so the build can be compared against the code — which is more than most installers allow. It still needs the permission to install unknown apps, so grant it to SAI specifically rather than site-wide, and revoke it when you are done if you prefer.
The install fails with a signature or parse error
Usually one of three things: an older version of the same app is already installed with a different signature, in which case uninstall it first; the archive is incomplete because the download was interrupted, so check the file size against the one published on the page; or the splits belong to a different CPU architecture than your phone. SAI reports which split failed, which narrows it down quickly.
Is the SAI (Split APKs Installer) APK safe to install?
Yes. We mirror the official Aefyr build and publish its SHA-256 checksum and a VirusTotal scan on this page, so you can verify the file is untouched before installing.
What is the SAI (Split APKs Installer) package name?
The Android application ID is com.aefyr.sai. Check it after installing (Settings → Apps) to confirm you got the genuine app.
