I am trying to send data from a C#.NET (Windows Application) program to a Java (Android App) program and vice versa, via TCP connection through Wifi. Till now I am success to send data from Java to C#, but unable to do so from C# to Java.
Following is the Java code, I used to create a connection and receive data:
ServerSocket serverSocket = null;
DataInputStream socketInputStream;
while (true) {
try {
String localIPAddr = getLocalIPAddress();
InetSocketAddress ipEndPoint = new InetSocketAddress(
InetAddress.getByName(localIPAddr), 8222);
serverSocket = new ServerSocket();
serverSocket.bind(ipEndPoint, 4);
workerSocket = serverSocket.accept();
socketInputStream = new DataInputStream(
workerSocket.getInputStream());
inputText.setText(socketInputStream.readUTF());
} catch (Exception ex) {
throw ex;
}
}
Here
getLocalIPAddress()
method returns the IP Address of the Android Device.
Following is the C# code in Windows Application to connect to the Android's IP Address (192.168.1.6) and send data to it:
Socket clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
void button1_Click(object sender, EventArgs e)
{
try
{
if (!clientSocket.Connected)
clientSocket.Connect(IPAddress.Parse("192.168.1.6"), 8222);
clientSocket.Send(Encoding.UTF8.GetBytes(txtInput.Text));
}
catch (Exception ex)
{
throw ex;
}
}
Well, client (C#) is failing to connect to the server (Java) That means data is not leaving from client. But it will, if it get connected.
Please tell me what am I missing and where am I mistaken. :)
