我有一个小问题，我无法自己解决。 当我在模拟器中启动应用程序时，它工作正常，但当我尝试在设备（SE X10和Galaxy ACE）上启动它时，应用程序运行2秒钟并崩溃。 我认为这是adMob问题但是......
这是logcat：

答案 0 :(得分：1)
看到/127.0.0.1:80？从你试图连接到localhost的东西的外观来看，这在设备的上下文中就是它自己。
Android设备可能没有运行网络服务器，因此看起来您错误配置了广告服务。

确保在网络线程上执行网络连接。这通常是您所描述的奇怪崩溃的原因。您可以阅读更多相关信息here。
您应该始终在单独的线程上执行可能长时间运行/昂贵的操作！
答案 2 :(得分：0)
在模拟器上，您可以使用localhost连接到您的计算机，但在真实设备上，您应该使用计算机的真实IP地址192.168.1.xxx
