[dev-dagger] Current filtering state is lost across process death

[Zhuinden]

In

architecture-samples/app/src/main/java/com/example/android/architecture/blueprints/todoapp/tasks/TasksViewModel.kt

Line 64 in 8b028e3

private var _currentFiltering = TasksFilterType.ALL_TASKS

The current filtering is not preserved in any way across process death, even though that is expected behavior. This was originally also a problem on master.

A possible solution would be to use a SavedStateHandle provided to the ViewModel from an AbstractSavedStateViewModelFactory.

I would expect this approach to be displayed in an example that is meant to "show how to use AAC ViewModel with Dagger", while still creating an app that works reliably even when it's put to background for a given period of time.

@Zhuinden Is there any way I can force this process death and observe the issue you are mentioning.
Like using an ADB command or some plugin tool on Android Studio?

Following the steps outlined in https://stackoverflow.com/questions/49046773/singleton-object-becomes-null-after-app-is-resumed/49107399#49107399 should work, although AS 4.0 had some quirkiness where the terminate button behaved differently. In that case, adb shell am kill packagenameis what works.
