带有facebook onCompleted函数的java.lang.NullPointerException

Question

我有一个问题

private class SessionStatusCallback implements Session.StatusCallback {
        @Override
        public void call(Session session, SessionState state,
                Exception exception) {
            if (session.isOpened()) {
                getProfileInformation();
                informDB();
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {

                    }
                });
            }
            updateView();
        }
    }



public void getProfileInformation() {
        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) {
                    // String access_token = session.getAccessToken();

                    profilePictureView.setProfileId(user.getId());
                    fbuser = new UserInfo(user.getId().toString(), user
                            .getName().toString(), null, null, null, null, null);

                    name = "dada";
                    us = user;

                    Toast.makeText(getApplicationContext(),
                            "Name: " + user.getName(), Toast.LENGTH_LONG)
                            .show();
                }

            }
        }).executeAsync();
        Log.e("errorrr", us.getName());
            Log.e("errorrr", name);
    }

我有一个函数getInformation（），其中我试图用GraphUser中的args创建一个UserInfo对象。 问题是fbuser变为null并且我有NullPointerException

你可以看到我设置了一个变量'name'，这是一个字符串但是这个我有同样的问题
