The Android Package with the file extension apk[1] is the file format used by the Android operating system, and a number of other Android-based operating systems for distribution and installation of mobile apps, mobile games and middleware. A file using this format can be built from source code written in either Java or Kotlin.

APK files can be generated and signed from Android App Bundles.[2]
