Socket client = new Socket("http://192.168.1.1/call", port);
System.out.println("Just connected to " + client.getRemoteSocketAddress()); 
OutputStream outToServer = client.getOutputStream();
DataOutputStream out = new DataOutputStream(outToServer);
out.write(bData);

"http://192.168.1.1/call" is an URL, "192.168.1.1" is an IP. so you are passing wrong argument, the program cannot understand...

“http://192.168.1.1/call”是一个URL,“192.168.1.1”是一个IP。所以你传递错误的论点,程序无法理解......
