A DEX file is a Dalvik Executable file, a code file for the Android operating system that can also be interpreted by the Dalvik virtual machine. Create DEX files manually as text files in a text editor, or automatically generate DEX files with Java code. Several DEX files combined and archived in a single APK package make up the final application package for the Android device. Create and open DEX files with the Google Android Software Developers Kit, or SDK, or with a text editor such as Notepad. Writer Bio
