Android XMPP registration

To register in XMPP server first of all you need to connect with XMPP server.

For register new user in XMPP server AccountManager class is used

To get account manager below code snippet is used

 
AccountManager accountManager = connection.getAccountManager();

For register new user in XMPP server below method is used.

createAccount("USERNAME", "PASSWORD")

For this example below is the code for xml file.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <Button
        android:id="@+id/btn_Register"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/button1"
        android:layout_below="@+id/button1"
        android:layout_centerInParent="true"
        android:layout_marginTop="38dp"
        android:text="Register" />

</RelativeLayout>

Use below activity for the register new user to XMPP server.

public class DemoActivity extends Activity{
 
 private Button btn_Register;
 XMPPConnection connection ;
 ConnectionConfiguration config;
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.demo_activity);
 
  StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
       .detectAll()
       .penaltyLog()
       .build();
   StrictMode.setThreadPolicy(policy);

  new ConnectToXmpp().execute();
  
  btn_Register = (Button) findViewById(R.id.btn_Register);
  btn_Register.setOnClickListener(new OnClickListener() {
 
   @Override
   public void onClick(View v) {
     try {
       AccountManager accountManager = connection.getAccountManager();
               accountManager.createAccount("USERNAME", "PASSWORD");
    } catch (XMPPException e) {
     // TODO Auto-generated catch block
     e.printStackTrace();
    }
            
   }
  });
 }
 private class ConnectToXmpp extends AsyncTask<Void, Void, Void> {
 
     @Override
     protected Void doInBackground(Void... params) {
           config = new ConnectionConfiguration("YOUR SERVER IP", PORT);
           connection = new XMPPConnection(config);
     try {
          connection.connect();
          connection.login("ADMIN LOGIN", "ADMIN PASSWORD");
     } catch (XMPPException e) {
         e.printStackTrace();
     } 
 
         return null;
     }
 
     @Override
     protected void onPostExecute(Void result) {
 
     }
