    <p>I'm writing a chat app which is connecting to a XMPP server, and if the user chooses, I want to give them the option to connect to their google chat account, without having to enter the credentials... I used google's javascript api to popout the google login form and after successful login access token will generate. Now using that access token and users email id i want to communicate with xmpp server so that users can chat with their gtalk friends.</p> <p>I searched a lot but didn't found the solution. Whatever i found required users password but i want to use access token. </p> <pre><code>SASLAuthentication.registerSASLMechanism("X-OAUTH2", GoogleConnectSASLMechanism.class); SASLAuthentication.supportSASLMechanism("X-OAUTH2", 0); config = new ConnectionConfiguration(server, 5222, 'gmail.com'); config.setSASLAuthenticationEnabled(true); config.setSecurityMode(SecurityMode.enabled); config.setReconnectionAllowed(true); connection = new XMPPConnection(config); connection.connect(); connection.login(username, session_key, "Chat"); setServer(SERVER_TYPE.GTALK); </code></pre> <p>GoogleConnectSASLMechanism.java code is as follows:-</p> <pre><code> package org.jivesoftware.smack; import java.io.IOException; import java.net.URLEncoder; import java.io.UnsupportedEncodingException; import java.security.MessageDigest; import java.security.NoSuchAlgorithmException; import java.util.GregorianCalendar; import java.util.HashMap; import java.util.Map; import javax.security.auth.callback.CallbackHandler; import javax.security.sasl.Sasl; import org.jivesoftware.smack.SASLAuthentication; import org.jivesoftware.smack.XMPPException; import org.jivesoftware.smack.packet.Packet; import org.jivesoftware.smack.sasl.SASLMechanism; import org.jivesoftware.smack.util.Base64; public class GoogleConnectSASLMechanism extends SASLMechanism { public static final String NAME="X-OAUTH2"; public GoogleConnectSASLMechanism(SASLAuthentication saslAuthentication) { super(saslAuthentication); } @Override protected String getName() { return NAME; } static void enable() { } @Override protected void authenticate() throws IOException, XMPPException { String authCode = password; String jidAndToken = "\0" + URLEncoder.encode( authenticationId, "utf-8" ) + "\0" + authCode; StringBuilder stanza = new StringBuilder(); //stanza.append( "&lt;auth mechanism=\"" ).append( getName() ); //stanza.append( "\" xmlns=\"urn:ietf:params:xml:ns:xmpp-sasl\"&gt;" ); // stanza.append( new String(Base64.encode( jidAndToken.getBytes( "UTF-8" ), Base64.DEFAULT ) ) ); stanza.append( "&lt;auth xmlns=\"urn:ietf:params:xml:ns:xmpp-sasl\" mechanism=\"" ).append( getName() ); stanza.append( "\" auth:service=\"oauth2\"" ); stanza.append( "\" xmlns:auth=\"http://www.google.com/talk/protocol/auth\"&gt;" ); stanza.append( "\" base64(\"\\0"+user_name+"\\0" + authCode+")" ); stanza.append( "&lt;/auth&gt;" ); //Log.v("BlueTalk", "Authentication text is "+stanza); // Send the authentication to the server getSASLAuthentication().send( new Auth2Mechanism(stanza.toString()) ); } public class Auth2Mechanism extends Packet { String stanza; public Auth2Mechanism(String txt) { stanza = txt; } public String toXML() { return stanza; } } /** * Initiating SASL authentication by select a mechanism. */ public class AuthMechanism extends Packet { final private String name; final private String authenticationText; public AuthMechanism(String name, String authenticationText) { if (name == null) { throw new NullPointerException("SASL mechanism name shouldn't be null."); } this.name = name; this.authenticationText = authenticationText; } public String toXML() { StringBuilder stanza = new StringBuilder(); stanza.append("&lt;auth mechanism=\"").append(name); stanza.append("\" xmlns=\"urn:ietf:params:xml:ns:xmpp-sasl\"&gt;"); if (authenticationText != null &amp;&amp; authenticationText.trim().length() &gt; 0) { stanza.append(authenticationText); } stanza.append("&lt;/auth&gt;"); return stanza.toString(); } } } </code></pre> <p>But I got an Exception from connection.login() that "username or password are not correct"</p> <p>To do this, I'd get the permission to use the google account, get the token and authenticate to google talk (XMPP server, using Smack) using the token..</p> <p>The problem is.. how do I do that? I mean, how do I authenticate to the GTalk server if I know the login and the token?</p> <p>Any help would be highly appreciated...:)</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
