Introduction to Android

• Open software platform for mobile development.

• Written in C(core), C++, Java(UI).• An Open Handset Alliance (OHA) project

powered by Linux operating system.• Fast application development in Java.• Open source under the Apache 2 license.

What is the Open Handset Alliance (OHA)?

→ It's a consortium of several companies

ANDROID APPLICATION DEVELOPEMENT

PREPAIRING TO DEVELOPE APPS IN ANDROID

• Must have Eclipse IDE installed.• Must have Android SDK installed.• Must have knowledge of Java.• Must have the external Google Maps library

installed in your SDK environment.• The Maps library is included with the Google APIs

add-on , which you can install using the Android SDK and AVD Manager.

DEVELOPMENT TOOL

• Android Emulator -A virtual mobile device that runs on our computer -use to design, debug, and test our applications in an actual Android run-time environment

• Android Development Tools Plugin -for the Eclipse IDE – adds powerful extensions to the Eclipse integrated environment

• Dalvik Debug Monitor Service (DDMS) -Integrated with Dalvik-this tool let us manage processes on an emulator and assists in debugging

Create an Android Virtual Device (AVD)

To create an AVD in Eclipse:1. Select Window > Android SDK and AVD Manager.

The Android SDK and AVD Manager displays.

2. Make sure the entry for Virtual Devices is selected and click New.The Create new AVD window displays.

3. Enter a Name for the AVD.4. Select Google APIs (API level 3) as the Target.5. Click Create AVD.6. Close the Android SDK and AVD Manager.
