在AndroidViewModel中使用BroadcastReceiver

Question

有人知道为什么我无法在ViewModel上下文中收听任何BroadcastReceiver吗？如果我在Activity，Fragment或Application本身内执行相同的代码，那么它将起作用。但是，从使用相同应用程序实例的ViewModel这样做，是行不通的。

这是基本代码：

class MyViewModel(application: Application) : AndroidViewModel(application) {
    init {
        registerBroadcastReceivers(application)
    }

    /**
     * Register for required broadcast receivers.
     */
    private fun registerBroadcastReceivers(application: Application) {
        application
            .registerReceiver(
                mLocationProviderChangedReceiver,
                IntentFilter(LocationManager.MODE_CHANGED_ACTION)
            )
    }

    /**
     * Broadcast receiver to monitor the changes in the location provider.
     */
    private val mLocationProviderChangedReceiver = object : BroadcastReceiver() {
        override fun onReceive(context: Context, intent: Intent) {
            Log.d("", "Received!") // <-- Never triggered when switching location
        }
    }
}

我发现an example可以完美地用Java编写，可以在AndroidViewmodel中使用相同的BroadcastReceiver，但是我仍然看不到虚拟项目中下面的代码有什么问题。
