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

概述嗨,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). 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！

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！

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！

解决方法 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");
