Android Facebook SDK 4.0.0 Sharing callback doesn't work properly

Question

I am using following code to share link on facebook. when user click on cancel on Share dialog interface,onSuccess() callback method is called sometimes instead of onCancel(). And getting post id null.Please help me what's going wrong?

ShareButton btn;
CallbackManager callbackManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(this);
    callbackManager = CallbackManager.Factory.create();
    setContentView(R.layout.activity_share);

    btn = (ShareButton) findViewById(R.id.btn_share);

    btn.registerCallback(callbackManager, new FacebookCallback<Sharer.Result>() {
        @Override
        public void onSuccess(Sharer.Result result) {
            Log.e("Tag","Successfully posted");
            Log.e("Post id",result.getPostId());
        }

        @Override
        public void onCancel() {

            Log.e("Tag","Canceled by user");

        }

        @Override
        public void onError(FacebookException error) {

            Log.e("Tag",error.getLocalizedMessage());
        }
    });
    ShareLinkContent content = new ShareLinkContent.Builder()
            .setContentUrl(Uri.parse("My Custom URL"))
            .setContentTitle("Test")
            .build();

    btn.setShareContent(content);

}

@Override
protected void onActivityResult(final int requestCode, final int resultCode, final Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    callbackManager.onActivityResult(requestCode, resultCode, data);
}

I'm having the same issues. Have you been able to resolve this? — cjserio
I'm also have the same problem and can't find a solution anywhere. Looks like a bug in Facebook SDK for Android or something is missing in the documentation. — Vadims Savjolovs

Well, maybe I'm late but I faced the same issue weeks ago. What I've noticed is if you press Cancel in the web-base Share dialog, the onSuccess() method is called but the Share.Result object contains a null postId, so you can control whenever the user pressed cancel or share by checking the Share.Result response.

Another thing I've noticed is that if you share content with native app installed, postId field is always null... so you will have to check if the user has the app installed to check or not the postId field.
