APK expansion files are the asset splitting solution for the APK publishing format. They enable an application to split its assets into:
The core assets go in the main APK file and the additional assets go in APK expansion files.
Digital distribution services often have an application size limit. This makes it necessary for APK applications that are larger than the size limit to use APK expansion files. For example, Google Play requires applications that are larger than 100MB to use APK expansion files. It allows you to use two APK expansion files, the main APK expansion file, and the patch APK expansion file, which can be up to 2GB each. For more information, see APK Expansion Files.
