Go To Path: Click Right (on the upper bar) - Copy Address

Step 2 : Install Android SDK (ADT Bundle)

You can download SDK from here: (Notice your OS 64bit (x64) or 32bit (x86))

http://developer.android.com/sdk/index.html

- You will get “ adt-bundle-windows-x86-20130514 “ zip folder for 32bit OS. - Installation will be done by unpacking the zip folder. - Resultant folder contains three items which are as the following:

1. eclipse 2. sdk 3. SDK Manager

(All the specifications of these items and other tools will be shown later)

Step 3 : Eclipse

- Open “eclipse” folder and launch “eclipse” (Type: application).

Main window will appear like

Step 4 : Prepare AVD (Android Virtual Device)

AVD is a simple tool that used to create Android emulator which represents the virtual

machine for a mobile device that enables the user to run his programs and to see his

results by very simple and friendly way. AVD will be created and edited by AVD Manager

Let’s start!

- Select Window >> Android Virtual Device Manager.

- Click New button. - AVD creation form will appear, fill it as the figure in the following page shows.

Notes:

- In the lab, we will use Android 4.2.2 Jelly Bean (API level 17) version.

- With AVD Manager, we can use any existent device with its own features as we need, or we can create our own device with needed features.

- Generally used device is 4.0 WVGA (400*800) screen resolution.

Directional pad (Control Pad) is not activated! >> Because of the hardware features of

the chosen device ….

Solution

We must edit the features of the device in order to enable the DPAD

1. Go to the AVD main form >> click New

2. Go to Device Definitions tab >> Choose 4.0 WVGA >> Click Clone

7

3. Give it any name you want >> in Input choices : choose DPAD

4. Your new device will be ready to be used

(You can click Create AVD and fill the form, or go to step 5)

5. Go to Android Virtual Devices tab >> click New >> fill the form like this

Choose your new device (with edited features)

6. Your emulator is ready to be used >> click Start

Part 2: What Does it Mean ?

- SDK (ADT bundle)

The Android Software Development Toolkit (SDK) provides you the API libraries and developer tools necessary to build, test, and debug apps for Android. For new Android developer, ADT Bundle is recommended to be used to quickly start developing apps. It includes the essential Android SDK components and a version of the Eclipse IDE with built-in ADT (Android Developer Tools) to streamline the Android app development.

With a single download, the ADT Bundle includes everything you need to begin developing apps:

Eclipse + ADT plugin Android SDK Tools Android Platform-tools The latest Android platform The latest Android system image for the emulator

The Android SDK is composed of modular packages that you can download separately using the

Android SDK Manager.

- Eclipse

Eclipse is an open-source IDE (integrated development environment) for Java development. Code will be written within it.

- ADT plugin

Android Development Tools is a plugin for the Eclipse IDE that provides a

powerful, integrated environment in which to develop Android apps. It extends the capabilities of Eclipse to let you quickly set up new Android projects, build an app UI, debug your app, and export app packages (APKs) for distribution.

The used release of the ADT Plugin in the lab is 22.0.0.

- DALVIK VM

DALVIK VM is the process virtual machine in android operating system; it is the software that runs the apps on android devices.
