JDK + Eclipse + ADT + SDK = Android development tools
Installing JDK:
Applications are written using the Java programming language and run on Dalvik, a custom virtual
machine designed for embedded use which runs on top of a Linux kernel.(Will be discussed in the
class hours)
First you need a copy of Java. All the Android development tools require it, and programs you write
will be using the Java language.
Note: JRE is not enough you need JDK. Make sure that you have installed the latest version of JDK.
To verify that you have installed java in your computer, run the following command from the
command prompt. Java -version
You should see something like this.

3. Getting started with Android
• If you haven’t installed java in your computer. Follow this link
and download the JDK Click here to download JDK
• Note: Make sure that you have downloaded the correct
version of the JDK. For example: Windows 32 bit.
 Get the Android SDK
• Before we start programming the android application we need
to set up the programming environment. The best resource for
developing Android apps is Android Developers.
• The Android SDK provides you the API libraries and
developer tools necessary to build, test, and debug apps for
Android.

4. Getting started with Android
• With a single download, the ADT Bundle includes everything
you need to begin developing apps:
1. Eclipse + ADT plugin
2. Android SDK Tools
3. Android Platform-tools
4. The latest Android platform
5. The latest Android system image for the emulator
Click here to get the ADT Bundle
• Note: Make sure that you have downloaded the correct
version of the ADT Bundle. For example: Windows 32 bit.
• There exists an option called other platforms where you can
download the ADT for other platforms as well like Mac and
linux.

5. Getting Started with Android
• If you are using an existing IDE you can go to the option Use
an excising IDE where you can download the SDK tools.
• Note: I recommend everyone to install the ADT
bundle, which is already loaded with the Android Developer
Tools plugin and the SDK and is ready to go.
 Setting Up the ADT Bundle
• Unpack the ZIP file (named adt-bundle-<os_platform>.zip)
and save it to a desired location, such as a "Development"
directory in your home directory.
• Open the adt-bundle-<os_platform>/eclipse/ directory and
launch eclipse.
• Now you are ready to build your first application in android.

6. Getting Started with Android
• Note: Don’t move any of the files from the default directory
to different location, if so it may not function properly.
• Eclipse IDE allows you to create and debug your Java
code, and manage the various resources that normally are
used in the making of an Android app.
• ADT (Android Developer Tools) is a plugin for Eclipse that
provides a suite of tools that are integrated with the Eclipse
IDE. It offers you access to many features that help you
develop Android applications quickly.
• SDK (Software Development Kit) that enables developers to
create applications for the Android platform. The
Android SDK includes sample projects with source
code, development tools, an emulator, and required libraries
to build Android applications.

7. Getting started with Android
• Open Eclipse by clicking on the eclipse icon
from the extracted folder.

8. Getting started with Android
• When you click on the Eclipse icon, this screen will appear

Android Virtual Device (AVD):
Defining:
Window-> Android Virtual Device Manager
On Android Virtual Device Tab click on “New” – Then create AVD as shown

16. Keywords
• Plug-in – A hardware or software module that adds a
specific feature or service to a larger system. The idea is that the new
component simply plugs in to the existing system.
For example, there are number of plug-ins for the Netscape
Navigator browser that enable it to display different types of audio
or video messages.
• IDE - A programming environment integrated into a software
application that provides a GUI builder, a text or code
editor, a compiler and/or interpreter and a debugger.
For example, Visual Studio, Eclipse are all examples of IDEs.
