DatabaseObjectNotClosedException：应用程序未关闭此处打开的游标或数据库对象

Question

当我通过Twitter在Digits中使用Firebase时，我遇到了这个例外。我正在使用来自twitter的数字。我找到了一个解决方案，但到现在为止我没有任何成功。 `

digitsButton.setCallback(new AuthCallback() {
        @Override
        public void success(DigitsSession session, String phoneNumber) {
            // TODO: associate the session user ID with your user model

            firebaseReference.addListenerForSingleValueEvent(new ValueEventListener() {
                @Override
                public void onDataChange(DataSnapshot dataSnapshot) {
                    if (dataSnapshot.hasChild(phoneNumber)) {
                        if (!dataSnapshot.getValue(String.class).equals(phoneNumber)) {
                            firebaseReference.setValue(phoneNumber);
                            firebaseReference.removeEventListener(this);

                            startActivity(new Intent(LoginActivity.this, SignupActivity.class));

                        } else {
                            firebaseReference.removeEventListener(this);
                            startActivity(new Intent(LoginActivity.this, MainActivity.class));

                        }
                    }
                }

                @Override
                public void onCancelled(DatabaseError databaseError) {

                }
            });

        }

        @Override
        public void failure(DigitsException exception) {
            Log.d("Digits", "Sign in with Digits failure", exception);
        }
    });

我已经被困在这几个小时，无法理解它是如何导致问题的
