Android中调用urlConnectoin.getInputStream 报错java.io.EOFException
首先，这段代码是我在Android中用程序直接读取百度百科的html页面，然后再到程序中解析，现在的问题是，它还没开始读，就已经报错了！
情况如下：
这是报错信息：

下面贴出来出问题的代码段：
String webUrl = "http://baike.baidu.com/searchword/?word="+nCode+"&pic=1";
//内置的百科页面地址
String contentUrl = "http://baike.baidu.com";
BufferedReader br = null;
String backLine = null;
URL url = null;
try {
url = new URL(webUrl);
Log.d("Avin","webUrl going open...");
URLConnection conn = url.openConnection();
Log.d("Avin","webUrl opened...");
Log.d("Avin","the question is-->"+question);
//异常信息显示是这一行报错
br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
backLine = br.readLine();
Log.d("Avin",backLine);
int clmindex = 1;
while(backLine != null){
backLine = br.readLine();
/*
if(clmindex == 20){
//跟踪到目标页面所在行，跳出循环
break;
}
*/
System.out.println(clmindex+"-->"+backLine);
clmindex++;
}
br.close();
br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
这一行报错！查了一天的资料，就是没进展，
这个异常意思是读取的文件异常结束了，返回的错误状态，但是看报错的代码行此时还没有开始读数据呢，怎么会异常结束呢，百思不得其解！
这段代码放在JavaProject中就没事，到我的手机上就不行！
好像是conn.getInputStream()出错了
我在stackoverflow上看到，有人是这样解的
System.setProperty("http.keepAlive", "false");
而且我们也验证过了，确实好用。
需要再mainFest.xml文件中配置访问网络的权限
<uses-permission android:name="android.permission.INTERNET"/> 其实就是线程的问题
