【问题描述】：

我有这段代码供 Android 获取 InputStream

URL myURL = new URL("http://www.echo.msk.ru/interview/rss-audio.xml");
URLConnection ucon = myURL.openConnection();
InputStream is = ucon.getInputStream();

不知何故，对于那个 URL http://www.echo.msk.ru/interview/rss-audio.xml，我总是遇到异常。但是我可以在浏览器中打开那个 URL...

java.net.UnknownHostException: Unable to resolve host "www.echo.msk.ru": No address associated with hostname
libcore.io.GaiException: getaddrinfo failed: EAI_NODATA (No address associated with hostname)
Unable to resolve host "www.echo.msk.ru": No address associated with hostname

有没有办法在 Java for Android 中以其他方式获取该资源/XML？

谢谢！

附：这是我的清单 xml

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="org.developerworks.android"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".MessageList"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
    <uses-sdk android:minSdkVersion="2" />

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

【解决方案1】：

使用 AsyncTask 发出 HTTP 获取请求

HttpClient httpclient = new DefaultHttpClient();
httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
HttpGet request = new HttpGet("http://www.echo.msk.ru/interview/rss-audio.xml");  
HttpResponse response = httpclient.execute(request);
HttpEntity resEntity = response.getEntity();
String  _response=EntityUtils.toString(resEntity); 
 Log.i(".......",_response);
