Why 2 versions? Did you try to remove one of them?

I am sorry, I mean upgrade to 1.0.0-rc1 from 1.0.0-preview05, I also tried 1.0.0-preview06 and it didn't work either.
All dependency libraries about androidx are below:

<ItemGroup>
    <PackageReference Include="Xamarin.AndroidX.Browser">
      <Version>1.0.0-preview02</Version>
    </PackageReference>
    <PackageReference Include="Xamarin.AndroidX.Legacy.Support.V4">

@Carl-Wen

Did you manually write this code snipett:

<PackageReference Include="Xamarin.AndroidX.Migration">
      <Version>1.0.0-preview05</Version>
      <Version>1.0.0-rc1</Version>
</PackageReference>

?

Try removing <Version>1.0.0-preview05</Version>

moljac · 2020-01-20T12:00:03Z

@Carl-Wen
Can you provide minimal repro sample please? I use Xamarin.AndroidX.AppCompat.Resources in 20+ samples and was not able to reproduce this issue.

... or maybe provide exact steps how to reproduce this issue.

Carl-Wen · 2020-01-21T08:26:21Z

@moljac Now I replace AndroidX with support libraries, I did reproduce it with other projects. But it works with below config a few days ago, I try to upgrade all libraries to the newest, but it isn't work either:

   <ItemGroup>
     <PackageReference Include="Xamarin.AndroidX.Browser">
       <Version>1.0.0-preview02</Version>
     </PackageReference>
     <PackageReference Include="Xamarin.AndroidX.Legacy.Support.V4">
       <Version>1.0.0-preview02</Version>
     </PackageReference>
     <PackageReference Include="Xamarin.AndroidX.Lifecycle.Extensions">
       <Version>2.0.0-preview02</Version>
     </PackageReference>
     <PackageReference Include="Xamarin.AndroidX.MediaRouter">
       <Version>1.0.0-preview02</Version>
     </PackageReference>
     <PackageReference Include="Xamarin.AndroidX.Migration">
       <Version>1.0.0-preview05</Version>
     </PackageReference>
     <PackageReference Include="Xamarin.AndroidX.VectorDrawable.Animated">
       <Version>1.0.0-preview02</Version>
     </PackageReference>
     <PackageReference Include="Xamarin.AndroidX.Work.Runtime">
       <Version>2.0.1-preview02</Version>
     </PackageReference>
     <PackageReference Include="Xamarin.AndroidX.ExifInterface">
       <Version>1.1.0-preview06</Version>
     </PackageReference>
     <PackageReference Include="Xamarin.Google.Android.Material">
       <Version>1.0.0-preview02</Version>
     </PackageReference>
   </ItemGroup>

I would like to point out that I was also experiencing this issue, tried everything, without any avail. It has something to do with older project configurations. For Example, the old project did not have packages.config, various differences in the .csproj file.

The solution I found was to create a new project, add all the same dependencies, copy over all the code and voilà, unable to reproduce the issue.

moljac · 2020-02-02T20:26:39Z

Yes. Older stale projects can produce issues.

General guidelines:

Migrate from packages.config to <PackageReference />

Visual Studio for Windows has option for migration.
Update all packagest to latest versions and test application

Manage NuGet packages for Solution in Visual Studio for Windows can consolidate all packages for
solution.
Change options for Android application (all configurations) [TODO]
1. aapt2
2. d8
3. r8
Add Xamarin.AndroidX.Migration package to the Android application and rebuild.
Fix issues reported by migration package (packages)

In Visual Studio for Windows unload project and edit project file (*.csproj) by adding code snippet
from migration package error.

In Visual Studio for Mac unloading is not necessary - project files can be edited directly.
Save, load/reload and rebuild application

This step will most likely fail with numerous errors due to source code not being migrated (namespaces,
fully qualified typenames).
Fix source code (build errors) from step 5.

This is manual step where Android.Support namespaces and [fully qualified] typenames must be replaced
with AndroidX counterparts. Use tooltips available in both IDEs (Visual Studio for Windows and Mac).

Do not forget migrating Android.Support packagenames in layout files (*.axml). Failing to do so will
cause runtime errors (inflation of binary XML file).

Closing this one

DevEddy · 2020-03-03T08:29:08Z

For me this issue only happens when I add the following configurations to my Android.csproj...

    <EnableLLVM>true</EnableLLVM>
    <AotAssemblies>true</AotAssemblies>
    <BundleAssemblies>true</BundleAssemblies>

I get error when build release, I just add Xamarin.AndroidX.Migration package. When I set true, it crash with error System.IO.FileNotFoundException: Could not load file or assembly 'Xamarin.AndroidX.AppCompat.Resources

I set fakse. My App Ok. How to resolve with option BundleAssemblies is true.

nhdanh · 2020-03-26T02:00:50Z

Same here 4.5.0.495 - still not working for me
