Android uses Dalvik VM

-
How many people know that the Android runs on the Dalvik Virtual Machine  ???


Dalvik is the virtual machine on Android mobile devices.
It runs applications which have been converted into a compact Dalvik Executable (.dex) format suitable for systems that are constrained in terms of memory and processor speed.
Dalvik was written by Dan Bornstein, who named it after the fishing village of Dalvík in Eyjafjörður, Iceland, where some of his ancestors lived.[1][2]

Unlike most virtual machines and true Java VMs which are stack machines, the Dalvik VM is a register-based architecture.

check http://www.dalvikvm.com/ for details of the .dex decompiled.
