gPhone开发简介

gPhone开发简介
--简单介绍gPhone上的应用软件开发过程

篇首语：准确来说应是“Android开发简介”，因为gPhone只是基于Android平台的一款手机。但gPhone更为大众所知并且是第一款基于Android平台的手机，所以。。。

gPhone OS--Android
Android上的应用软件开发都是用JAVA，IDE用Eclipse（需下载插件）。

HelloWorld
贴HelloAndroid.java的代码在下面：
//HelloAndroid.java
package com.android.hello;

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

public class HelloAndroid 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);
}
}

Eclipse控制台输出：

上面关于Android开发的资料一应俱全啦。。。

结论：
1. 速度奇慢
2. 调试不大方便，感觉Android下的开发还需要待以时日来成熟...
