JavaWhatsApp

This project has been continued by DevSplash on this repo: https://github.com/DevSplash/WhatsApp4Java

Send and listen messages through WhatsApp from a Java Program.

This is done thanks to Yowsup: https://github.com/tgalal/yowsup

This works as is today but it hasn't been tested deeply, I just shared it because it may be helpful for someone.

 Steps

• Register your phone number in yowsup, follow these instructions. https://github.com/tgalal/yowsup/wiki/yowsup-cli-2.0

• Fill the fields in yowsup/yowsup-cli.config

  • cc=
  • phone=
  • id=
  • password=

• The Whatsapp folder is a Netbeans Maven project that contains a package with all the necessary. It also has a demo to show how it works.

  
  package com.nqysit.whatsapp;
  
  import java.util.ArrayList;
  
  public class EchoDemo {
  
      public static void main(String[] args) throws ClientIsNotInit {
  
          boolean run = true;
  
          Client.init("/usr/bin/python", "JavaWhatsApp/yowsup/yowsupclient.py");
  
          while (run) {
  
              Client.ListenIncomingMessages();
  
              ArrayList<Contact> unreaden = Client.getUnseenContacts();
  
              if (!unreaden.isEmpty()) {
  
                  for (Contact ur : unreaden) {
  
                      String from = ur.getNumber();
                      String text = ur.getUnseenMessage();
  
                      System.out.println(from + "-" + text);
  
                      if (text.equals("stop")) {
                          Client.killit();
                          run = false;
                          break;
                      }
  
                      Client.sendMessage(from, text);
  
                  }
  
              } else {
  
                  System.out.println("There are not new messages");
  
              }
          }
      }
  
  }
