    <p>I had the same issue. </p> <p>One call is coming from UiLifecycleHelper when it invokes the callback:<br></p> <pre><code>UiLifecycleHelper callback onSessionStateChange() </code></pre> <p>The other comes from Activity resuming the LoginFragment.</p> <pre><code>LoginActivity.onResumeFragments() LoginFragment.onResume() onSessionStateChange() </code></pre> <p>In many cases, this is fine, but in your case it's obviously a problem due to the AsyncTask.</p> <p>You can cache the session received in onSessionStateChange() and see if its state and tokenInfo changed, and only then invoke your async task. Checking the combination of session state and tokenInfo should suffice:</p> <pre><code>private void onSessionStateChange(Session session, SessionState state, Exception exception) { if (state.isOpened()) { if (mSession == null || isSessionChanged(session)) { mSession = session; LogUtils.LOGFB(TAG, "Logged in using facebook"); LogUtils.LOGFB(TAG, "Access Token: " + session.getAccessToken()); // Run your AsyncTask } } else if (state.isClosed()) { LogUtils.LOGFB(TAG, "Logged out from facebook"); // Display your non-authenticated UI } } private boolean isSessionChanged(Session session) { // Check if session state changed if (mSession.getState() != session.getState()) return true; // Check if accessToken changed if (mSession.getAccessToken() != null) { if (!mSession.getAccessToken().equals(session.getAccessToken())) return true; } else if (session.getAccessToken() != null) { return true; } // Nothing changed return false; } </code></pre>

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).
