Bind and Listen for Incoming Connections

See more Socket/SSL/TLS Examples

Demonstrates Socket.BindAndListen, which binds a TCP listener to a port and places it into listening mode, then accepts an incoming connection.

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
package com.test;

import android.app.Activity;
import com.chilkatsoft.*;

import android.widget.TextView;
import android.os.Bundle;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    boolean success = false;

    CkSocket socket = new CkSocket();

    //  Bind a TCP listener to a port and place it into listening mode.  The 2nd argument is the backlog,
    //  the maximum number of pending connections allowed to queue.
    success = socket.BindAndListen(5000,25);
    if (success == false) {
        Log.i(TAG, socket.lastErrorText());
        return;
        }

    //  After the listener is established, accept the next incoming connection into a new Socket.
    CkSocket connectedSock = new CkSocket();
    success = socket.AcceptNext(20000,connectedSock);
    if (success == false) {
        Log.i(TAG, socket.lastErrorText());
        return;
        }

    Log.i(TAG, "Accepted a connection.");

  }

      System.loadLibrary("chilkat");

      // Note: If the incorrect library name is passed to System.loadLibrary,
      // then you will see the following error message at application startup:
      //"The application <your-application-name> has stopped unexpectedly. Please try again."
