Overview
 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?
 The Android SDK provides you the API libraries and developer
tools necessary to build, test, and debug apps for Android.

11. Android Programming
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.

Project Structure
 Inside the Manifest
 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

Running and Debugging
 Create a new Android Virtual Device (AVD) if you do
not have any.
 From the Window menu, select AVD Manager
 From the AVD Manager window, click New button
 Input
• Name: API-16
• Target: Android 4.1 – API Level 16

Running and Debugging
 From the Run menu, select Run or Debug
 If you’ve using the ADT plug-in, running or
debugging your application:
 Compiles the current project and converts it to an Android
executable (.dex).
 Packages the executable and external resources into Android
package (.apk).
 Starts the emulator (if it’s not already running).
 Installs your application onto the emulator.
 Start your application.
