c# - TelecomManager：AddNewIncomingCall() 上的异常

Question

我正在尝试在我的 Xamarin.Forms 应用程序中使用电信功能。当调用 AddNewIncomingCall() 时，抛出异常：

Java.Lang.SecurityException: 包 com.android.phone 不属于 10134

这是代码：

        Xamarin.Forms.Device.BeginInvokeOnMainThread(async () =>
        {            
            TelecomManager telecomManager = (TelecomManager)Application.Context.GetSystemService(TelecomService);

            // https://docs.microsoft.com/en-us/xamarin/essentials/permissions?tabs=android
            PermissionStatus status = await Permissions.CheckStatusAsync<ReadPhoneStatePermission>();
            if (status != PermissionStatus.Granted)
            {
                status = await Permissions.RequestAsync<ReadPhoneStatePermission>();
            }

            PhoneAccountHandle phoneAccountHandle = telecomManager.CallCapablePhoneAccounts.FirstOrDefault();
            
            telecomManager.AddNewIncomingCall(phoneAccountHandle, new Bundle());
        });

我该如何解决这个问题？
