I am using facebook 3.15 android SDK. I am using following code to get the username and other details of the logged in user:
private final String[] PERMISSIONS = new String[] { "public_profile", "email" };
//this function gets called when user clicks on facebook login button
public void onFbButtonClick(View v) {
Session session = Session.getActiveSession();
if (!session.isOpened() && !session.isClosed()) {
session.openForRead(new Session.OpenRequest(this).setPermissions(Arrays.asList(PERMISSIONS)).setCallback(callback));
} else {
Session.openActiveSession(this, true, callback);
}
}
private Session.StatusCallback callback = new Session.StatusCallback() {
@Override
public void call(Session session, SessionState state, Exception exception) {
onSessionStateChange(session, state, exception);
}
};
private void onSessionStateChange(Session session, SessionState state, Exception exception) {
if (state.isOpened()) {
Log.i("Logged in...");
// make request to the /me API
Request.newMeRequest(session, new Request.GraphUserCallback() {
// callback after Graph API response with user object
@Override
public void onCompleted(GraphUser user, Response response) {
if (user != null) {
Log.d("user.getName : " + user.getName());
Log.d("user.getUsername : " + user.getUsername());
Log.d("user.getId : " + user.getId());
String email = user.getProperty("email").toString();
Log.d("user.email : " + email);
}
}
}).executeAsync();
} else if (state.isClosed()) {
Log.i("Logged out...");
}
}
My code is working fine except the part that where i am printing the username. It is showing null in the logs. Any idea why this is happening? I have provided the necessary permissions.
The field username is no longer existing in the Graph API v2.0, so you can't use it.

/me/usernameis no longer available
