 What is ADT?
 Android Development Tools (ADT) is a plugin for the Eclipse IDE
that is designed to give you a powerful, integrated environment
in which to build Android applications.
 http://developer.android.com/tools/sdk/eclipse-adt.html
 What is SDK?

Overview
 What is NDK?
 The NDK is a toolset that allows you to implement parts of your
app using native-code languages such as C and C++. For
certain types of apps, this can be helpful so that you may reuse
existing code libraries written in these languages and possibly
increased performance.

 Here is where you declare what is inside your application—the
activities, the services, and so on.
 When you create your application, you will get a starter manifest
generated for you.
 Underneath the manifest element, you will find the following:
• uses-permission
• permission
• Instrumentation
• uses-library
• uses-sdk
