Build an android environment (Windows)

Preface

I have seen a lot of articles about Android recently, and I am eager to experience android, so I found some articles on how to build android in windows on the Internet. I would like to share with friends who are not getting started and interested in me. I hope you will be helpful.

Body

　　Download

1 download JDK http://www.oracle.com/technetwork/java/javase/downloads/index.html.

2. If there is no eclipse, you also need to download an eclipse http://www.eclipse.org/

3 SDK download http://developer.android.com.nyud.net/sdk/index.html

4 ADT (Android development tools) download the same page

　　Install

1. Install JDK and configure the environment variables.

Configuration method http://tieba.baidu.com/F? Kz= 899066778

2. Install eclipse (if not)

3. Configure/install the android SDK

3.1 Add the installation path to JDK java_home configuration and test the command Android -- help. If any help information is displayed, the configuration is successful.

3.2 open setup.exe in the sdkinstallation directory

Note: perform the following settings before installing the SDK:

　　　　　　　　

Then, click installed packages to install an SDK platform (you can also choose to install it all, but you must install at least one. Otherwise, you cannot create an avd vm)

4. Install ADT

Click Create AVD and then OK.

6. Start the simulator.

Run cmd to go to the tool directory of the SDK and enter the name of step 5 of the command emulator-AVD. The following will appear in a short time:

　　　　　　

7. The above interface indicates that the installation is successful.

1. Create an android project. If the environment is successfully installed, see:

　　　　

2 Sample Code

　　　　　　　　

Code

 package test.android;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class HelloWorld extends Activity {
/** Called when the activity is first created. */
    @Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
        TextView tv = new TextView(this);
        tv.setText("Hello Android");
        setContentView(tv);
    }

Then run the project (CTRL + F11), select androin application, and run. The simulator starts slowly. The following figure appears after waiting patiently:

　　　　

The first Android hello program is finally completed. Wish everyone a smooth job and study!
