Android application package file (APK)

Android application package file (APK) is the file format used to
distribute and install application software and middleware onto
Google's Android operating system. To make an APK file, a program for
Android is first compiled, and then all of its parts are packaged into
one file. This holds all of that program's code such as (.dex files),
resources, assets, certificates, and manifest file. As is the case
with many file formats, APK files can have any name needed, but must
end with the four character, three letter extension, .apk.[1][2][3][4]
APK files are ZIP file formatted packages based on the JAR file format.
