Integrate Facebook chat in android with Asmack API

Question

I try to implement chat support as suggested in this blog.

Currently, I\'m using following code to implement chatting interface.

Java Code

Answer 1

I have checked all code of Beem Project and found the solution for connecting with Facebook chat API.

Steps for implementing Facebook chat API in Android:

1. First we have to implement MemorizingTrustManager Library project in existing project.

   => For that you have to copy following three files in existing project

   • MemorizingTrustManager/src/de/duenndns/ssl/MTMDecision.java
   • MemorizingTrustManager/src/de/duenndns/ssl/MemorizingActivity.java
   • MemorizingTrustManager/src/de/duenndns/ssl/MemorizingTrustManager.java

   => And add following values in values/string.xml

   <resources>
       <string name="mtm_accept_cert">Accept Unknown Certificate?</string>
       <string name="mtm_decision_always">Always</string>
       <string name="mtm_decision_once">Once</string>
       <string name="mtm_decision_abort">Abort</string>
       <string name="mtm_notification">Certificate Verification</string>
   </resources>
   

2. Second step, Instead of using SASLAuthentication such as X-FACEBOOK-PLATFORM, You can used following code to connect with Facebook and login using your Facebook Jabber ID (username@chat.facebook.com)

   public void connectToFb() throws XMPPException {
   
   ConnectionConfiguration config = new ConnectionConfiguration("chat.facebook.com", 5222);
   config.setSASLAuthenticationEnabled(true);
   config.setSecurityMode(SecurityMode.required);
   config.setRosterLoadedAtLogin(true);
   config.setTruststorePath("/system/etc/security/cacerts.bks");
   config.setTruststorePassword("changeit");
   config.setTruststoreType("bks");
   config.setSendPresence(false);
   try {
       SSLContext sc = SSLContext.getInstance("TLS");
       sc.init(null, MemorizingTrustManager.getInstanceList(this), new java.security.SecureRandom());
       config.setCustomSSLContext(sc);
   } catch (GeneralSecurityException e) {
       Log.w("TAG", "Unable to use MemorizingTrustManager", e);
   }
   XMPPConnection xmpp = new XMPPConnection(config);
   try {
       xmpp.connect();
       xmpp.login("facebookusername", "****"); // Here you have to used only facebookusername from facebookusername@chat.facebook.com
       Roster roster = xmpp.getRoster();
       Collection<RosterEntry> entries = roster.getEntries();
       System.out.println("Connected!");
       System.out.println("\n\n" + entries.size() + " buddy(ies):");
       // shows first time onliners---->
       String temp[] = new String[50];
       int i = 0;
       for (RosterEntry entry : entries) {
           String user = entry.getUser();
           Log.i("TAG", user);
       }
   } catch (XMPPException e) {
       xmpp.disconnect();
       e.printStackTrace();
   }
   }
   

At last, If you get all the Buddy list of your Facebook account in LogCat View, than you can implement simple Facebook chat using this tutorial.

UPDATE : I'm also working on sample app that work as Facebook Messenger and posted on GitHub soon.
