POProgram proceeds before Facebook Graph API responds -- How can I make it wait?
text
Body
copied!<p>Here's what's happening:</p> <ul> <li>My program updates when there is a state change</li> <li>The handler for the state change needs to know the user's ID before proceeding; it calls findUserID()</li> <li>findUserID() requests the user's ID from the Facebook Graph API</li> <li>The handler for the state change proceeds before that value if found and therefor behaves incorrectly.</li> <li>A few seconds later, the trace (Log.d) displays that the user's ID has been found</li> </ul> <p>If I pause and then resume my program, the user ID is noticed and then my program behaves correctly; however, this should NOT need to be done. How do I make my program wait for the Facebook Graph API's response before proceeding?</p> <pre><code>protected void findUserID(Session session) { //userId = null; // Set initial // If session is open if (session != null && session.isOpened()) { // Make an API call to get user data // and define a new callback to handle the response Request request = Request.newMeRequest(session, new Request.GraphUserCallback() { @Override public void onCompleted(GraphUser user, Response response) { Session session = Session.getActiveSession(); // If current session matches active session if (session == Session.getActiveSession()) { if (user != null) { userId = user.getId(); // set userId Log.d("internal", "UserId issss: " + userId); } // end if user != null } // end if session == Session.getActiveSession() } // end onCompleted }); // end request Request.executeBatchAsync(request); // Request does not execute unless you call this. Log.d("findUserID", "The value after request: " + userId); } // end session open check } </code></pre> <p>Any/all help is appreciated.</p>
