這是仿真器還是真實設備？我會懷疑你沒有網絡連接。 – techiServices 2010-12-19 10:08:12

UnknownHostException是我每次在沒有連接的情況下發出HTTP請求時在代碼中獲得的內容。來自仿真器的 – 2010-12-19 10:14:45

，來自真實設備的認證窗口進入和離開不執行任何操作。 – om252345 2010-12-19 10:17:38

您需要添加使用互聯網的應用程序的權限。如果你不這樣做，應用程序會拋出這個錯誤。

進入清單，並加入這一行：

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