Android新手之旅(4) 通过HTTP访问web

manifest中应该增加一个

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

最好通过交互界面添加。代码：

public static String GetWebInfo2()
{
String ret="";
URL url=null;
try
{
url=new URL("http://www.cnblogs.com/jetz/archive/2011/07/11/2102755.html");
}
catch(MalformedURLException e)
{
ret=e.getMessage();
//Log.e("AccessWeb","MalformedURLException");
}
if(url!=null)
{
try
{
HttpURLConnection urlConn=(HttpURLConnection)url.openConnection();
InputStreamReader in=new InputStreamReader(urlConn.getInputStream());
BufferedReader buffer=new BufferedReader(in);
String inputLine=null;
while(((inputLine=buffer.readLine())!=null))
{
ret+=inputLine+"\n";
}
in.close();
urlConn.disconnect();
}
catch(IOException e)
{
ret=e.getMessage();
}
}
return ret;

}
