Android java.net.UnknownHostException:无法解析主机；谷歌网站“；

我正在Galaxy选项卡（v1）上运行我的应用程序。
我添加了

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

我运行它，它抛出异常：

你试过使用google.com而不仅仅是google.com吗

正如@SLaks所说，您的方法是错误的，因为您在启动线程后返回，需要使用回调（类似于您在iOS中对代理所做的操作）。

您的方法从根本上被破坏了；您将在线程运行之前返回该值。如果你等待线程，你会冻结你的应用程序，这正是你应该避免的。你需要使用回调或承诺。我会在它运行之前返回它吗？I

.start（）

将其关闭，然后在关闭后返回no。你

.start（）

，然后立即返回。还有其他人也有类似的问题；
