android - 清除 ViewModel 抛出 IllegalArgumentException

Question

我有一个ViewModel由一个Activity初始化并由多个Fragments共享，所以我有一个仅存在于一个Activity的应用程序。

当我删除我当前的设备时，我也会手动清除我的ViewModel

activity?.viewModelStore?.clear()

在此之后，我回到另一个片段并调用

bleDeviceViewModel = ViewModelProvider(requireActivity()).get(BleDeviceViewModel::class.java)

抛出以下错误->
