--------

1.安装java jdk去oracle公司下载

jdk-7u15-windows-i586.exe
http://www.oracle.com/technetwork/cn/java/javase/downloads/jdk7-downloads-1880260-zhs.html
---

C:\Documents>

package com.example.hello3;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;

import android.widget.*;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView textView = new TextView(this);
textView.setText("Hello Android!");
setContentView(R.layout.activity_main);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}

}

8.运行

选中项目->Run As->Android Application

等待编译链接后，eclipse会自动调用手机模拟器，然后你就可以在模拟器里面找到你刚才编写的程序了，点击运行，看看是否达到你要的效果。（这个过程对电脑配置要求挺高的，时长几分钟不等）

9.打包生成apk

选中项目->右键->Android Tools->Export Signed/Unsigned Application Package

10.卸载手机上安装的调试程序

命令adb>
