Building a Android Development Environment

Note: This article provides a summary of the simple process of installing the android Development Environment on my host by referring to relevant online tutorials.

1. Official setup steps:

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

2. Download the related development software (taking android4.0 as an example ):

2.1 Jave related software:

Install the Java Runtime Environment JRE (this eclipse cannot run) and JDK.

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

Install JRE first and then JDK.

Android SDK 2.2

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

Android SDK is a free-of-Installation Software. After downloading the software package, extract the software package directly to a directory on the disk.

After the package is decompressed, three related folders or files are visible in the first-level Directory: Eclipse folder, SDK folder, and SDK manager.exe executable file.

Attacked

To C: \ windows \ system32 \ drivers \ etc hosts to join # Google homepage 203.208.46.146 www.google.com # This line is to facilitate opening the android development official website. Now it seems that no Fan Qiang can open 74.125.113.121 pai.android.com download the URL 203.208.46.146 DL. google. com203.208.46.146 dl-ssl.google.com

If the message is "failed to fetch URL ..." So you need to change the HTTPS mode to the http mode, as shown in the following figure:

Go to SDK maneger.exe and run packages-> reload to reload all versions of Android platform, as shown in:

After the installation is complete, you need to restart eclipse. After the restart, eclipse will automatically pop up the path of the specified SDK, select use existing sdks, existing
Location is the SDK path in step 2,

Next> finish.

　　

　　ADT installation is complete ....

Different from previous versions, SDK management and ADT management are separated and have two icons

4. Configure the android Simulator

Click the button on the right (like a mobile phone), open the AVD manager, click New to create a simulator, enter name avd4.0, specify target to select android4.0, then the size of the SD card is allocated to 256 MB, and then create AVD.

　　

　　AVD created ....

 

5. Our Hello World (we run it together !)

Select File> New> Android project and name it helloworld.

Write code:

 

1 package Allen. Liu. helloworld;

2

3 Import Android. App. activity;
