And for those who had never heard the name "Dalvik" before
(like yours truly):

"Dalvik is the process virtual machine (VM) in Google's Android
operating system. It is the software that runs the apps on Android
devices. Dalvik is thus an integral part of Android, which is typically
used on mobile devices such as mobile phones and tablet computers.
Programs are commonly written in a dialect of Java and compiled
to bytecode. Then they are converted from Java Virtual Machine-
compatible .class files to Dalvik-compatible .dex (Dalvik Executable)
files before installation on a device. The compact Dalvik Executable
format is designed to be suitable for systems that are constrained
in terms of memory and processor speed."
