IssueTracker

Seems to be a DNS problem with systems that have 'obtain DNS server address automatically'. Changed my system to a manual setting and the browser etc now work. SDK 2.2 didn't seem to mind the auto setting though.

Could you please describe how/where you changed your system to a manual setting?

Based on its date, this issue was originally reported before Android 2.3. Because of the many changes that existed in Android 4.x compared to previous versions, it's very likely that this issue doesn't exist in recent versions of Android like 4.2.2 or newer. Because of the high likelihood that this issue is obsolete, it is getting closed automatically by a script, without a human looking at it in detail. If the issue still exists on a Nexus 4 or Nexus 7 running Android 4.2.2 and is not related to Google applications, please open a new report accordingly.

    Use default factory for navGraphViewModels()
   
    Ensure that navGraphViewModels() works as
    expected with SavedState ViewModels so that it
    uses the correct default factory associated
    with the navigation graph.
   
    Test: new test passes

As part of this change:
- the SavedStateViewModelFactory(Fragment) and SavedStateViewModelFactory(FragmentActivity) constructors have been removed (as viewmodel-savedstate no longer depends on Fragments)

- When you use the ViewModelProvider(ViewModelStoreOwner) constructor or ViewModelProviders.of() with an Activity / Fragment / Navigation Graph ViewModelStoreOwner, you'll be using the correct SavedStateViewModelFactory - no custom factory is needed

- When you use the Kotlin property delegates such as 'by viewModels()', 'by activityViewModels()' or 'by navGraphViewModels()', you'll be using the correct SavedStateViewModelFactory - again, no custom factory needed

This will be part of:
- androidx.lifecycle viewmodel 2.2.0-alpha03
- androidx.lifecycle viewmodel-savedstate 1.0.0-alpha03
- androidx.activity 1.1.0-alpha02
- androidx.fragment 1.2.0-alpha02
- androidx.navigation 2.2.0-alpha01

It seems like this change causes an exception such as:

Fatal Exception: java.lang.IllegalArgumentException
SavedStateProvider with the given key is already registered

Using the latest fragment/architecture component dependencies.

I am using "by activityViewModels" to get my viewModel, and "requireActivity().viewModelStore.clear()" to destroy it. Then, when getting the viewmodel is called again, it crashes because of the mentioned exception.

Re #10 - please file a new bug with a sample project that reproduces your issue.
