我有一个简单的Facebook登录注销活动,该活动正在成功运行.

但是,在我从应用程序注销后,我尝试再次登录,但facebook提供了无效的密钥哈希错误.

请注意,我第一次成功登录并注销,但在我退出并尝试再次登录后,Facebook会出现该错误.应该做什么？

谢谢你的关注.

这是我的代码:

public class MainFragment extends Fragment {

private static final String TAG = MainFragment.class.getSimpleName();

private UiLifecycleHelper uiHelper;

private final List<String> permissions;

public MainFragment() {
    permissions = Arrays.asList("user_status");
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    uiHelper = new UiLifecycleHelper(getActivity(), callback);
    uiHelper.onCreate(savedInstanceState);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.activity_main, container, false);

    LoginButton authButton = (LoginButton) view.findViewById(R.id.authButton);
    authButton.setFragment(this);
    authButton.setReadPermissions(permissions);

    return view;
}

@Override
public void onResume() {
    super.onResume();
