Android's Process Virtual machine

There is no Java Virtual Machine in the Android platform. Java byte code is not executed. Instead Java classes are compiled into Dalvik executables and run on Dalvik, a specialized virtual machine (VM) designed specifically for Android. Unlike Java VMs, which are stack machines, the Dalvik VM is a register-based architecture.
