Android版的URLConnection并只在wifi的随着3G工作，而不是 [英] Android URLConnection does only work in wifi, not with 3g

问题描述

我写它使用一个URLConnection的得到一个.html文件的应用程序。
一切都通过WiFi工作正常。但在3G上的文件没有正确返回。
当我尝试通过浏览器访问该网站，它工作正常。
任何人有一个建议？

更新：
这里是我的code：

  URL downloadUrl;
URLConnection的downloadConnection;
InputStream的InputStream的;
字节[] inputBytes;
的String []输出;
私人无效downloadSource（字符串金银丝）
{    尝试
    {
        downloadUrl =新的URL（金银丝）;        downloadConnection = downloadUrl.openConnection（）;
        downloadConnection.setConnectTimeout（10000）;
        downloadConnection.setReadTimeout（10000）;
        的InputStream = downloadConnection.getInputStream（）;
        ByteArrayOutputStream结果=新ByteArrayOutputStream（）;        inputBytes =新的字节[10000]
        INT I;
        INT的i1 = 0;
        而（（ⅰ= inputStream.read（inputBytes））大于0）
        {
            result.write（inputBytes，0，I）;
            result.flush（）;
            I1 + =我;
        }
        result.flush（）;
        result.close（）;
        输出= result.toString（）分裂（\\ n）;    }
    赶上（例外五）
    {
        e.printStackTrace（）;
    }
}
 

解决方案

也许这是迟到的回答一点点，但我有同样的问题，与WiFi下载的HTML有一个比随着3G下载不同的空间。

我解决它删除用户代理的连接：

 的URLConnection康恩= url.openConnection（）;
conn.setRequestProperty（用户代理，）;
 

我希望它可以帮助别人！

I have written an app which uses an URLConnection to get a .html file. Everything works fine over wifi. But over 3g the file is not returned correctly. When i try to access the website via the browser it works fine. Anyone has a suggestion?

Update: Here is my code:

URL downloadUrl;
URLConnection downloadConnection;
InputStream inputStream;
byte[] inputBytes;
String[] output;
private void downloadSource(String pUrl)
{

    try
    {
        downloadUrl = new URL(pUrl);

        downloadConnection = downloadUrl.openConnection();
        downloadConnection.setConnectTimeout(10000);
        downloadConnection.setReadTimeout(10000);


        inputStream = downloadConnection.getInputStream();
        ByteArrayOutputStream result = new ByteArrayOutputStream();

        inputBytes = new byte[10000];
        int i;
        int i1 = 0;
        while ((i = inputStream.read(inputBytes)) > 0)
        {
            result.write(inputBytes, 0, i);
            result.flush();
            i1 += i;
        }
        result.flush();
        result.close();
        output = result.toString().split("\n"); 

    }
    catch (Exception e)
    {
        e.printStackTrace();
    }


}

解决方案

Maybe it's a little bit late for answer but I had the same problem, with Wifi the html downloaded had different spaces than the one downloaded with 3G.

I solved it deleting the User-Agent in the connection:

URLConnection conn = url.openConnection();  
conn.setRequestProperty("User-Agent","");

I hope it helps someone!
