Android Package (APK) is a container file format for distribution and installation of applications for the Android operating system. It is an extension of both the Java Archive format and the ZIP container format.

File format identification signatures
The format can be identified because it contains a file named AndroidManifest.xml at the root level. Note that it should have priority over both the ZIP format (x-fmt/263) and the Java Archive format (x-fmt/412).
