WorkerParameters not working after upgrading to 4.3.0.819712-pre2

[jrahma]

Hi,

Why I am started getting this error:

The type 'WorkerParameters' exists in both 'Xamarin.Android.Arch.Work.Runtime, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' and 'Xamarin.AndroidX.Work.Runtime, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'

Everything was working before and I don't have the Xamarin.AndroidX.Work.Runtime in my installed Nuget packages.

This happend after installing the latest Xamarin Forms preview 4.3.0.819712-pre2

How can I resolve this please?

Thanks,
Jassim

After adding Xamarin.AndroidX I am now getting:

Program type already present: androidx.versionedparcelable.CustomVersionedParcelable

I believe this is due to the fact that Google decided to name the api's for work manager using the androidx package name in the Android Support library, so having both the old Xamarin.Android.Arch.Work.Runtime and Xamarin.AndroidX.Work.Runtime packages installed is unnecessary and in this case problematic.

Can you try removing Xamarin.Android.Arch.Work.Runtime from your project and rebuilding?

Since the .NET managed API should be the same in both packages, this should still allow you to 'migrate' without changing your managed .net code.

I already tried that but did not work

I had to downgrade by opting out the preview version

@jrahma do you have a repro sample you could share?

[jrahma]

nope, but I will try to make it and update you

@mattleibow i suspect we're going to need to update the mapping files for the migration package to account more appropriately for this scenario...
