Answer 1

您忘记了清单文件中的互联网权限。

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

之后，您将获得networkonmainthreadexception，因为您正在主线程中执行Web请求使用另一个AsyncTask或其他线程。

Answer 2

您必须为清单文件添加互联网权限：

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

Android也不会让你在主线程中进行http连接，以获取更多信息：

http://developer.android.com/reference/android/os/AsyncTask.html

Answer 3

你确实忘记了添加

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

中的

。

但之后您将收到networkmainthreadexception，为避免这种情况，您需要使用AsyncTask或额外的thread。如果您在使用这些内容时遇到问题，请阅读post，这可能会对您有所帮助。
