How to Implement Xmpp chat android

I want to imaplement xmpp connection in my application i refered lot of tutorials in google,but i cnnot get clear idea.
please some one help me out this problem,give suggetion how to implemnt xmpp connection.
thank you.

first You Have to add build.gradle
compile "org.igniterealtime.smack:smack-android:4.1.0-rc1"
compile "org.igniterealtime.smack:smack-tcp:4.1.0-rc1"
compile "org.igniterealtime.smack:smack-im:4.1.0-rc1"
compile "org.igniterealtime.smack:smack-extensions:4.1.0-rc1"
then create LocalBinder class
public class LocalBinder<S> extends Binder {
private final WeakReference<S> mService;
public LocalBinder(final S service) {
mService = new WeakReference<S>(service);
}
public S getService() {
return mService.get();
}
}
Then Create service class
public class XmppService extends Service {
public static MyXMPP xmpp;
private String ServiceName = "", HostAddress = "";
private String USERNAME = "";
private String PASSWORD = "";
private SessionManager sessionManager;
#Override
public IBinder onBind(final Intent intent) {
return new LocalBinder<XmppService>(this);
}
#Override
public boolean onUnbind(final Intent intent) {
return super.onUnbind(intent);
}
#Override
public void onCreate() {
sessionManager = new SessionManager(XmppService.this);
ServiceName = Your Service Name ;
HostAddress = Your Host Address;
USERNAME = your xmpp server user name;
PASSWORD = Your xmpp server pwd;
xmpp = MyXMPP.getInstance(XmppService.this, ServiceName, HostAddress, USERNAME, PASSWORD);
xmpp.connect("onCreate");
}
#Override
public int onStartCommand(final Intent intent, final int flags,
final int startId) {
return Service.START_NOT_STICKY;
}
#Override
public void onDestroy() {
super.onDestroy();
MyXMPP.instance=null;
MyXMPP.instanceCreated=false;
xmpp.connection.disconnect();
System.out.println("--------------Xmpp Service Stopped-----------");
}
}
create xmpp class

add to manifest

Start xmpp service
startService(new Intent(myclass.this, XmppService.class));
stop xmpp service

You can integrate Quickblox API it has multiple features like User Management, Chat, Group Chat, Video & Audio Calling.

Android Chat app XMPP

I have created an android chat application using XMPP server (openfire) and smack lib. When open my application i get connect =>connecting than a Oncreat SMACK exception appears. Which means that i can't establish a connexion with the server my code looks right but i cant figure out where is the probleme

You are getting the exception because in class ObdGatewayService your class member mChatservice is not the same as mChatservice in class LiveFragment
They are just different member variables
mChatservice gets assigned like this in your Fragment
mChatService = new BluetoothChatService(getActivity(), mHandler);
You need to pass this reference to ObdGatewayService 's startService() like this where ever you are instantiating/invoking it:-
ObdGatewayService ogs;
....
ogs.startservice(mChatservice); // This is fragment's member reference
And in ObdGatewayService you have to assign it accordingly:-
public void startService(BluetoothChatService _mChatservice) throws IOException {
Log.d(TAG, "Starting service..");
bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
mChatservice = _mChatservice //Assignment YOU ARE MISSING THIS
.......
.......

This is doable

http://androidexample.com/Incomming_Phone_Call_Broadcast_Receiver__-_Android_Example/index.php?view=article_discription&aid=61

Make a broadcast receiver to know about incoming call
write that code in AndroidManifes.xml
<receiver android:name=".ServiceReceiver" >
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
and make a new a class like that.
public class ServiceReceiver extends BroadcastReceiver {
#Override
public void onReceive(final Context context, Intent intent) {
TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
telephony.listen(new PhoneStateListener(){
#Override
public void onCallStateChanged(int state, String incomingNumber) {
if(state.equals(TelephonyManager.EXTRA_STATE_RINGING)){
// Run the flash in that line
}
}
},PhoneStateListener.LISTEN_CALL_STATE);
}

I'm trying too login to the android app that i have created whose authentication will be done using the username and password registered in ejabberd. The connection is successfully established but i'm not abe to login. It gives an error namely -
