2.4. Dalvik

Dalvik is a purpose-built virtual machine designed specifically for Android, developed by Dan Bornstein and his team at Google.

The Java virtual machine (VM) was designed to be a one-size-fits-all solution, and the Dalvik team felt they could do a better job by focusing strictly on mobile devices. They looked at which constraints specific to a mobile environment are least likely to change in the near future. One of these is battery life, and the other is processing power. Dalvik was built from the ground up to address those constraints.
