.DEX File Extension

A DEX file is an executable file saved in a format that contains compiled code written for Android, Google's Linux-based mobile phone platform. It is technically referred to as a "Dalvik Executable," and can be interpreted by the Dalvik virtual machine.

DEX files can be created manually or by automatically translating compiled Java programs. Multiple DEX files are zipped into a single .APK package, which serves as the final Android application file.
