启用proguard后片段无法正常工作

Question

我有包含 recyclerview 的片段。如果未启用 progaurd，则一切正常。如果我启用 progaurd，则来自 API 的数据不会设置。如果我放置断点，它不会到达构造函数，但片段正在设置，recyclerview 显示空数据。

我添加了progaurd规则也请查看

class NotificationListFragment : Fragment {

    private lateinit var notificationListViewModel: NotificationListViewModel
    private lateinit var notificationListFragmentBinding: NotificationListFragmnetBinding
    private var roles: String = ""
    constructor()
    constructor(roles: String) {
        this.roles = roles
    }
    override fun onCreateView(
            inflater: LayoutInflater,
            container: ViewGroup?,
            savedInstanceState: Bundle?
    ): View? {
        notificationListViewModel = NotificationListViewModel(requireActivity().application, requireActivity(), roles)
        notificationListFragmentBinding = DataBindingUtil.inflate(inflater, R.layout.notification_list_fragmnet, container, false)
        notificationListFragmentBinding.notificationListViewModel = notificationListViewModel
        notificationListFragmentBinding.lifecycleOwner = this
        setHasOptionsMenu(true)
        getNotificationList()
        return notificationListFragmentBinding.root
    }

    private fun getNotificationList() {
        notificationListViewModel.notificationListData.observe(viewLifecycleOwner, Observer {
            if (!it.isNullOrEmpty() && it.size > 0) {
                Log.d("TAG", "value::" + it.size)
                val notificationListAdapter = NotificationListAdapter(it, requireActivity(), notificationListViewModel.refresh)
                rvNotificationList.layoutManager = LinearLayoutManager(activity, RecyclerView.VERTICAL, false)
                rvNotificationList.adapter = notificationListAdapter
            }
        })
    }
    interface Refresh {
        fun refreshRecyclerView();
    }
}

am calling this fragment from my main activity like this

setFragment(new NotificationListFragment(Constant.name));



private void setFragment(Fragment fragment) {
        try {
            FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
            fragmentTransaction.replace(R.id.main_container_wrapper_sales, fragment);
            fragmentTransaction.commit();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

我发现了问题。及其解决。当启用 progaurd 时，firebase class 文件被删除，所以我添加了一个规则，然后它被解决了。

-keep class com.google.firebase.** { *; }
