没有到主机的路由 - Android 客户端 TCP 连接

发布于 2025-01-07 11:21:38 字数 654 浏览 1 评论 0原文

我正在编写一段代码，其中 Android 手机是客户端，尝试使用 WIFI 连接到我的电脑上的服务器。我按如下方式打开套接字：

try {
  servsock = new ServerSocket(13299);
  System.out.println("Listening :13299");
} catch (IOException e) {
  e.printStackTrace();
}

while (true) {
  Socket sock = servsock.accept();

在客户端：

Socket sock = new Socket("192.168.0.108", 13299);
Log.i("sending","sending");

但是我在 logcat 上收到：“没有到主机的路由”我已在 manifest.xml 中搜索并插入了使用互联网的权限，并使用 ip 从我的手机执行了 ping 操作192.168.0.107 到 ip 192.168.0.108 的 PC 服务器。

我缺少什么？为什么tcp套接字连接没有建立？服务器是用netbeans编写的。跟端口有关系吗？

编辑：我认为问题出在IP 地址上。我根据cmd窗口中“ipconfig”的输出设置服务器的地址（私有地址）。

原文

I am writing a code where the android phone is the client trying to connect to the server on my pc USING WIFI. I am opening the sockets as follows:

try {
  servsock = new ServerSocket(13299);
  System.out.println("Listening :13299");
} catch (IOException e) {
  e.printStackTrace();
}

while (true) {
  Socket sock = servsock.accept();

and on client side:

Socket sock = new Socket("192.168.0.108", 13299);
Log.i("sending","sending");

However I am receiving on the logcat: "No route to host" I have searched and inserted permission to use internet in the manifest.xml and did a ping from my phone with ip 192.168.0.107 to the pc server with ip 192.168.0.108.

What Am I missing? Why isn't the tcp socket connection established ? the server is written in netbeans. Does it have to do with the ports?

EDIT: I think the problem is in the IP addresses. I set the address of the server (private address) according to the output of "ipconfig" in cmd window.
