ALWAYS result false from getNativeDialogDidComplete in onComplete for Facebook MessageDialogBuilder in onActivityResult

In Android Facebook SDK 3.20, we implemented the MessageDialogBuilder interface and the onComplete and onError events. ARE is called after the user interacts with Messenger.

The user logged into FaceBook using the FaceBook sign in. But we have NO results from getNativeDialogDidComplete (ALWAYS false) and getNativeDialogCompletionGesture (always NULL).

Has anyone on Android got this to return a result and completion? We have set trackPendingDialogCall now.

We can see that he is working on the Apple Facebook SDK. Not sure what we're missing here, or if it's an unfinished item in the Android Facebook SDK?
