Android 14 上下文注册的广播接收器不起作用

Question

我正在 Android 14 设备上试验我的应用程序，我发送本地广播，然后在应用程序内订阅它。但是，当我使用该RECEIVER_NOT_EXPORTED选项时，根本没有收到广播。

下面是我正在使用的代码：

class DashboardFragment : Fragment() {
private var \_binding: FragmentDashboardBinding? = null

    // This property is only valid between onCreateView and
    // onDestroyView.
    private val binding get() = _binding!!
    
    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View {
        val dashboardViewModel =
            ViewModelProvider(this).get(DashboardViewModel::class.java)
    
        _binding = FragmentDashboardBinding.inflate(inflater, container, false)
        val root: View = binding.root
    
        binding.button.setOnClickListener {
            Intent("com.nama.action").also { intent ->
                intent.putExtra("nama", dashboardViewModel.text.value)
                requireContext().sendBroadcast(intent)
            }
        }
    
        val textView: TextView = binding.textDashboard
        dashboardViewModel.text.observe(viewLifecycleOwner) {
            textView.text = it
        }
    
    
        val br: BroadcastReceiver = MyBroadcastReceiver()
        val filter = IntentFilter("com.nama.action")
        ContextCompat.registerReceiver(requireContext().applicationContext, br, filter, ContextCompat.RECEIVER_NOT_EXPORTED)
    
    
        return root
    }
    
    override fun onDestroyView() {
        super.onDestroyView()
        _binding = null
    }

}

当我运行时，RECEIVER_EXPORTED我能够接收广播。根据Google文档，我们不需要导出同一应用程序中使用的本地通知？

我在这里错过了什么吗？

对于具有自定义操作的意图，您需要在发送广播时指定包名称。

intent.setPackage(context.packageName)
