Build an Android development environment

Android Development Environment ConfigurationWindows7 built the Android development environment, integrated several strategies, modified some of these errors, and some configuration omissions to complement.
The work is good to the good, its prerequisite
August 2014 13-Dayby Lilihao q:404536204

1. Installing the JDK and Java environment variable settings

(1). JDK:

Installation package:

Http://www.oracle.com/technetwork/java/javase/downloads/index.html

You need to remember the installation path of the JDK.

(2). Configure environment Variables for Java

The configuration path under Win7 is:

Start >> Control Panel >> System and Security >> Systems >> Advanced system settings >> System variables

Several environment variables that need to be configured are:

Java_home=c:\program Files\java\jkd1.8.0_11 (the path you just installed, the default path)

Java_jre_home=%java_home%\jre

Jre_home=c:\program Files\java\jre8

Path=%android_sdk_home%\platform-tools;%android_sdk_home%\tools;%java_home%\bin;%jre_home%\bin;%java_jre_home %\bin

Classpath=.; %java_home%\lib;%java_home%\lib\tools.jar;%java_home%\lib\dt.jar;%jre_home%\lib;%jre_home%\lib\rt.jar;%java_ Jre_home%\lib;%java_jre_home%\lib\rt.jar

Test environment variables are set correctly or not:

Start >> Run Cmd>>java

Start >> Run Cmd>>javac

The usage hints are displayed

2. Install Eclipse

(1). Eclipse:

Installation package:

http://www.eclipse.org/downloads/

General Select Eclipse Standard Version

(2). Configuring the Eclipse working directory

Eclipse for Java and Android IDE, do not need to install, just set up a working directory

Workspace:e:\developer\android

3. Install the Android SDK

To be exact, download the Android SDK Manager and AVD Manager and download the available SDK automatically by downloading the SDK manager.

(1). Android SDK:

Installation package:

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

The address seems to be a river crab, need to turn over the wall to download, Web page prompts to download a separate SDK

Use an EXISTING IDE

Download the SDK tools for Windows

(2). Install the SDK and remember the installation path

E:\android-sdk

(3). Setting Environment variables

Setup method Same as Step 1 ANDROID_SDK_HOME=E:\ANDROID-SDK

(4). Test the installation of the SDK

Start >> Run cmd>>adb

Tip: Android Debug Bridge version 1.0.31.

4. Install Eclipse Plugin ADT Android provides an ADT plugin for the Eclipse IDE called Android Development Tools (ADT).1. Start Eclipse,help>>install New software>>addFill out ADT Plugin in name and fill in location http://dl-ssl.google.com/android/eclipse/2. Download the Tools window list and click Next.
3, accept the software license Agreement, the Warning window Click OK, restart the prompt window, click, Restart now.
4. Restart Eclipse and configure the ADT plugin. WINDOWS>>PREFERENCE>>ANDROID>>SDK Location
5. Before downloading the SDK, the SDK Manager recommends downloading the latest version from the official website, and there may be some situations where some packages cannot be downloaded or not in the list at all. The SDK can start the download directly from the installed Sdk-manager, or the Sdk-manager is already associated with Eclipse, and is launched through Eclipse. Prior to this, to improve the download speed of the SDK, you can make a partial modification of the Win7 host file(1). Modify the Win7 Hosts file to add the following:C:\Windows\System32\drivers\etc\hosts203.208.46.146 www.google.com
74.125.113.121 developer.android.com
203.208.46.146 dl.google.com
203.208.46.146 dl-ssl.google.com
197.80.128.44 developer.android.com

(2). Eclipse>>windows>>android SDK Manager

The entire download process lasts about 2 hours.

6. Create an Android emulator

1. Open ECLIPSE>>WINDOWS>>AVD Manager

2, new A virtual machine, the parameters are not very strict

Name: Emulator names

Target: Version with ADK

SDcard Size: How large the memory card is

Skin: Screen Size

3, after the creation, Launch, would like to create a mobile phone, the result is such a big Google screen

7. Add Android Application project in Eclipse to open eclipse. Menu barwindows>>customize perspective>>shortscuts>>android Application Project>>OK

8. Create a hello-android program1. Open eclipse,new>> Android application Project
among them:Project name : project NamesContents: Radio box A project or import an existing project
Build Target: Choose which jdk to use
Application Name: Application name
Package Name: Creating Packages
Create activity: Creates an activity if you're a Java EE programmer This is the equivalent of Struts's action class
Min SDK version:jdk version
2, creation success, directory description
SRC: java source file is the file code of the Java suffix name that we wrote, step a Mainactivity.java file created
Gen:android automatically generated a directory and created an R file in this directory
android 4.4W: library file, which is the core file of Android
Res.: directory where resource files are placed
androidmanifest.xml: Project description File
3, launch an Android emulator and put the project file run as Android application.

As a Linux server for four years, I was delighted with the first piece of Android-helloworld.
