Question

我有一个大问题。我无法从android模拟器连接到Java服务器套接字。我有日志和代码：

我正在使用2.1版（Eclair）模拟器来运行我的Android应用程序。

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错误：

我需要更多权限吗？

Answer 1

127.0.0.1是模拟器的ip。 10.0.2.2是您正在寻找的（模拟器运行的主机）

Answer 2

首先确保你在你的清单文件中添加了Internet权限，然后确保你的主机和端口号都正确，最后检查你是否有权访问该主机+端口。

无法连接到互联网，拒绝连接
