Android TCP客户端套接字
在我的服务器中，我向套接字发送一个无限循环（“编号：%d\n”，I）。在每一个循环中，我增加一个数字。然后，我使用以下代码在android设备（即TCP客户端）中接收它： 而{Android TCP客户端套接字,android,sockets,tcp,client,Android,Sockets,Tcp,Client,在我的服务器中，我向套接字发送一个无限循环（“编号：%d\n”，I）。在每一个循环中，我增加一个数字。然后，我使用以下代码在android设备（即TCP客户端）中接收它： 而{ //receive data through socket BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream())); Log.d

if（nbytesIt确实识别'\n'，但java会删除它，因为您使用的是readLine（）。服务器代码是什么，使用什么语言？您是否正在创建自定义协议？为什么不使用json/web服务等现有技术？我认为您必须创建一个套接字轮询器，并轮询此套接字以获取数据。这里有一些q/a。。此链接也可能有帮助。我已使用服务器代码编辑了问题。它是C.write（）返回写入的字节数。第三个参数应该是字符串的长度。请检查返回值是否等于发送字符串的长度。我在客户端中没有看到接收行的循环。我看到两个readlines（）你只使用一个。android的代码在一个循环中。我忘了添加它。我也将两个读线改为一个读线，但仍然有相同的问题。
