Android 无法在TabHost内登录并在facebook上共享

我在我的项目中使用Facebook SDK版本3.5.2。我有一个有三个标签的TabHost，我在其中一个上使用Facebook共享。我正在使用WebDialog进行共享，但当我单击“共享”按钮时，它只会打开一个空白活动，并在2-3秒后自动关闭

以下是使用Facebook共享的活动代码

private void publishFeedDialog() {



    Session.openActiveSession(More.this.getParent(), true,
            new Session.StatusCallback() {

                @Override
                public void call(Session session, SessionState state,
                        Exception exception) {
                    // TODO Auto-generated method stub



                    if (session.isOpened()
                            && !session.getPermissions().contains(
                                    "publish_actions")) {
                        session.requestNewPublishPermissions(new NewPermissionsRequest(
                                More.this.getParent(), "publish_actions"));
                        Bundle params = new Bundle();
                        /*
                         * params.putString("name", titleString);
                         * params.putString("caption", addressString);
                         * params.putString("description",
                         * descriptionString);
                         */
                        params.putString("caption", msgString);
                        // params.putString("link", linkString);

                        params.putString("picture",
                                "live_image_path/logo.jpg");

                        WebDialog feedDialog = (new WebDialog.FeedDialogBuilder(
                                More.this.getParent(), Session
                                        .getActiveSession(), params))
                                .setOnCompleteListener(
                                        new OnCompleteListener() {
