    <p>With Facebook's new Android SDK 3.0 (that was released a few days ago), the process of authentication has changed.</p> <p>So how do you request a read permission such as "friends_hometown"?</p> <p>The following code is how I am trying to do it - but I'm quite sure it's not the way you should do this:</p> <p><strong>Version 1:</strong></p> <pre><code>protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Session.openActiveSession(this, true, new Session.StatusCallback() { // start Facebook login @Override public void call(Session session, SessionState state, Exception exception) { // callback for session state changes if (session.isOpened()) { List&lt;String&gt; permissions = new ArrayList&lt;String&gt;(); permissions.add("friends_hometown"); session.requestNewReadPermissions(new Session.NewPermissionsRequest(FBImport.this, permissions)); Request.executeGraphPathRequestAsync(session, "me/friends/?access_token="+session.getAccessToken()+"&amp;fields=id,name,hometown", new Request.Callback() { ... }); } } }); } </code></pre> <p><strong>Version 2:</strong></p> <pre><code>protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Session currentSession = Session.getActiveSession(); if (currentSession == null || currentSession.getState().isClosed()) { Session session = Session.openActiveSession(this, true, fbStatusCallback); // PROBLEM: NO PERMISSIONS YET BUT CALLBACK IS EXECUTED ON OPEN currentSession = session; } if (currentSession != null &amp;&amp; !currentSession.isOpened()) { OpenRequest openRequest = new OpenRequest(this).setCallback(fbStatusCallback); // HERE IT IS OKAY TO EXECUTE THE CALLBACK BECAUSE WE'VE GOT THE PERMISSIONS if (openRequest != null) { openRequest.setDefaultAudience(SessionDefaultAudience.FRIENDS); openRequest.setPermissions(Arrays.asList("friends_hometown")); openRequest.setLoginBehavior(SessionLoginBehavior.SSO_WITH_FALLBACK); currentSession.openForRead(openRequest); } } } </code></pre> <p>What I'm doing is to request the permission as soon as the session is open - but at this point the code is already starting a Graph API request, thus the permission request comes to late ...</p> <p>Can't you request a permission at the same time you initialize the session?</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
