android – 如果我的应用程序在API 8模拟器上运行,则Internet连接无法正常工作

嗨,谢谢你的帮助,
我有一个应用程序,我在 Eclipse中针对API 17进行编译.

该应用程序执行一些简单的Internet连接.

现在,当我在使用API​​ 17的仿真器上进行测试时,一切正常.

如果我使用API​​ 8对模拟器进行测试,那么App显然无法执行网络连接(adMob dos显示,HttpGet显然没有检索任何东西……)从我的应用程序(模拟器上的Web浏览器工作正常并正常加载).

并且adMob也不会加载到具有API 8或10的仿真器(它在API 17仿真器上).

非常感谢任何帮助！

这是我的主要活动：

甚至在API 10英特尔加速仿真器上尝试过,没有更好的运气

代理设置正确,

数据传输已启用

……我有点绝望了！

发布整个活动

该应用程序在使用API​​ 10的真实电话上正常工作(不在我的模拟器上使用API​​ 10)！

我抓到的错误是

03-15 13:14:43.299: E/Exception(1318): java.net.UnknownHostException: www.google.com

我确实使用Google REST服务

谢谢你的帮助！

我很确定这是代理设置问题.尝试显式设置代理(从Android系统获取值).

在默认的HttpClient上,这将是：

HttpClient client = new DefaultHttpClient();

//Get the default settings from APN
  String proxyHost = android.net.Proxy.getDefaultHost();
  int proxyPort = android.net.Proxy.getDefaultPort();
//Set Proxy params of client, if they are not the standard
    if (proxyHost != null && proxyPort > 0) {
        HttpHost proxy = new HttpHost(proxyHost, proxyPort);
        client.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);
    }
HttpGet request = new HttpGet("http://www.google.com");
