SAI – Split, install, backup and export APKs

In the Android ecosystem, facing the increasing size and complexity of applications, Google Play sometimes adopts a new format when distributing programs - Android App Bundle (with extension name .apks, AKA: split APKs), which enables developers to create multiple APK files that are optimized for different device configurations, such as screen sizes, CPU architectures, and languages. Unlike traditional APK file, which is a standalone package, split APKs are packaged together to create a more efficient distribution mechanism.
