Android SDK 2.2 Development Environment Installation

This document describes the installation process of the android SDK, including: Android SDK 2.2, eclipse 3.5.2 (Galileo), and andoid development tools (ADT) plugin.

One premise is that you have installed JDK 6.0 or JDK. The path contains the JDK bin directory in the system environment variable.

[Install Android 2.2]

1. Download the "start package" of Android 2.2"

Windows: android-sdk_r06-windows.zip Mac edition: android-sdk_r06-mac_86.zip Linux edition android-sdk_r06-linux_86.tgz

You need to know that this zip package is not a complete package. The Android software package adopts the form of "components". You can select components as needed. The preceding ZIP file contains only one component management tool and one basic tool component.

2. run Android SDK and AVD manager.

Decompress the zip package and run the SDK setup.exe to start the andoid SDK and AVD manager. This tool not only manages the android SDK components, but also the android Virtual Device Manager. (For the latter, see the following example ).

Then, you can use this tool to download the complete Android SDK. Note that if the network uses a proxy server, you need to (possibly) configure the proxy server domain name and port in this tool.

[Create a virtual device]

After the development environment is set up, you can write a "hello World" application. However, you still need to create a virtual device.

Run eclipse and select Window> Android SDK and AVD manager.

On the left-side pane, select Virtual Devices.

Click new.

The create new AVD dialog box appears.

Enter the AVD name, for example, "my_avd ".

Select a target. The target is a platform (that is, the android SDK version, such as 2.2)

Temporarily ignore other settings

Click Create AVD.

[Hello world]

1) create a new Android Project

After creating AVD, the next step is to start a new Android project in eclipse.

Run eclipse and select File> New> project.

If the ADT plug-in is correctly installed, there should be an item in "android project": "android ". (After you create one or more Android projects, an "android XML file" portal should also be visible .)

Select "android project" and click Next.

Enter the following project information:

Project name: helloandroid

Application name: Hello, Android

Package name: COM. example. helloandroid (or your own private namespace)

Create activity: helloandroid

Click Finish.

2). CompileCode: Print Hello android

Package com. Android. helloandroid;

Import Android. App. activity;

Import Android. OS. Bundle;

Import Android. widget. textview;

Public class helloandroid extends activity {

@ Override

Public void oncreate (bundle savedinstancestate ){

Super. oncreate (savedinstancestate );

Textview TV = new textview (this );

TV. settext ("Hello, Android ");

Setcontentview (TV );

}

}

3) Run

ADT makes running very simple:

Select Run> Run.

Select "Android Application ".
