Dalvik is a process virtual machine in Google's Android operating system that executes applications written for Android.

dalvik-exchange is the tool that takes in class files and reformulates them for consumption in the VM. It also does a few other things.

This program is officially named "dx" but in order to avoid naming conflict with OpenDX in Debian it is renamed to "dalvik-exchange".

This package also provides the "mainDexClasses" program.
