android - fragment 中未调用 registerForActivityResult

Question

我最近迁移到用于注册请求权限的最新回调机制但是从未触发用于注册请求回调的最新 api 我正在附加代码 fragment ，任何人都可以帮助我找出问题所在，

        @AndroidEntryPoint
class ManageTeamFragment : Fragment(), View.OnClickListener {

    @Inject
    lateinit var manageTeamViewModel: ManageTeamViewModel

    private var requestMultiplePermissions:ActivityResultLauncher<Array<out String>>? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        requestMultiplePermissions =
            registerForActivityResult(ActivityResultContracts.RequestMultiplePermissions()) {
                println("DEBUG $it")
                if (allPermissionsGranted()) {
                    btnAddUser.showLoading(true)
                    btnAddUser.postDelayed({
                        (activity as? DashboardActivity)?.navToFragment(AddUserFragment(), true)
                    }, 10)
                } else {
                    if (addOrEditUserBottomSheet == null) {
                        addOrEditUserBottomSheet =
                            AddOrEditUserBottomSheet(toolbar.context, addOrEditUserInteractionsListener)
                    }
                    addOrEditUserBottomSheet?.showBottomSheet()
                }
            }

    }


    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {



        return inflater.inflate(R.layout.fragment_manage_team, container, false)
    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        initViews()
        initViewModels()
        // Inflate the layout for this fragment

        btnAddUser.setOnClickListener {
            println("DEBUG requesting")
            requestMultiplePermissions?.launch(REQUIRED_PERMISSIONS)
        }
    }
}

梯度依赖

implementation 'androidx.activity:activity-ktx:1.2.0-alpha05'
implementation 'androidx.fragment:fragment-ktx:1.3.0-alpha05'

我遇到的问题是给定的 Activity 在 AndroidManifest.xml 文件中被标记为 android:noHistory="true"。
它应该是这样的:

<activity
            android:name=".activity.PaletteAddActivity"
            android:noHistory="false" />
