無法連接到互聯網，連接拒絕

Question

我有一個大問題。我無法從android模擬器連接到Java服務器套接字。我有日誌和代碼：

我使用的是2.1版本（埃克萊爾）模擬器來運行我的Android應用程序。

System.out.println("Sup"); 
try{ 
    Socket socket = new Socket("127.0.0.1", 26753); 
    PrintWriter out = new PrintWriter(socket.getOutputStream(), true); 
    out.println("e:ask"); 
    out.println("p:pass"); 
    out.println("EOF"); 
    socket.close(); 
} catch (Exception e){ 
    e.printStackTrace(); 
} 

logcat的錯誤：

我需要更多的權限？

Answer 1

127.0.0.1是模擬器的IP。 10.0.2.2是你在找什麼（在模擬器上運行的主機）

Answer 2

首先，確保你把網上的權限在您的清單文件，並確保您的主機和端口號是正確的，並最後檢查你是否有權訪問該主機+端口。
