Dalvik is a purpose built virtual machine designed specifically for android.
which was developed by Dan Bornstein and his team. Strictly it was developed for mobile devices.
The role of dalvik virtual machine is that, In java we write and compile java program using java compiler and run that bytecode on the java virtual machine.
On the other side, In android we still write and compile java source file(bytecode) on java compiler, but at that point we recompile it once again using dalvik compiler to dalvik bytecode(dx tool converts java .class file into .dex format) and this dalvik bytecode is then executed on the dalvik virtual machine.
My History
Started even before Google (Android, a start up California before 2005).
4Americans called Andy Rubin,Rich miner,Chris white and Nick sears started developing android in 2001.
But Android Inc is failed and google decided to buy in 2005.
Google developed the original android O/S with some changes and completed it in 2007
Android Co Founder Andy Rubin him self was the chief of the project.

Virtual Machine
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 byte code.
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.

SDK Software Development Kit
Android
The Android SDK includes a variety of tools that help you develop mobile applications for the Android platform.
The tools are classified into two groups:
SDK tools and platform tools. SDK tools are platform independent and are required no matter which Android platform you are developing on.
Platform tools are customized to support the features of the latest Android platform.
The SDK tools are installed with the SDK starter package and are periodically updated. The SDK tools are required if you are developing Android applications.
The most important SDK tools include the Android SDK and AVD Manager (android), the emulator (emulator), and the Dalvik Debug Monitor Server (ddms).
A short summary of some frequently-used SDK tools is provided below.
