Extension(s)	.art

ART (Android Runtime) is a new format for Android executables introduced with Android 5.0 "Lollipop" (with a preliminary version available earlier in Android 4.4 "KitKat"), replacing Dalvik Executable (DEX). It is still "virtual code" independent of the actual machine hardware, but instead of being interpreted on the fly, it is compiled in advance at the time an app is installed on an Android device.

Both ART and DEX executables typically come to the end user embedded in an APK installation archive.
