warning XA4214: The managed type `xxxx` exists in multiple assemblies

[LeoJHarris]

I have just bumped into this annoying issue that seems to have come out of now where. Previously up to a week ago this was working and now its not working and I have done nothing to change the binding library, the only thing that changed was VS did an update and now I am having a problem with retrofit2 as per below. I have a binding library that need this library and so I used the jars to create the bindings library I also had included the nuget Square.Retrofit2.ConverterMoshi which resolved a exception I was getting also... All of this was working until a week ago and now out of no where I cannot build my application...

The the error log below....

[LeoJHarris]

If I remove the Square.Retrofit2.ConverterMoshi nuget then I can run the application again but when I try to use the binding library from my application it throws an exception:

Java.Lang.NoClassDefFoundError: 'Failed resolution of: Lcom/squareup/moshi/Moshi$Builder;'

This was exactly the reason why I had the Square.Retrofit2.ConverterMoshi nuget installed so that this exception did not get thrown but now I cant even build the application so I am not sure what to do.

[jpobst]

Your error is caused by having 2 bindings of the same library, causing the duplicate types.

The NuGet Square.Retrofit2.ConverterMoshi has a dependency on Square.Retrofit2, so it is pulling in a binding of Retrofit2 already.

Are you able to use this binding of Retrofit2 instead of writing your own?

[LeoJHarris]

@jpobst to be honest I would much rather use the binding of Retrofit included in the NuGet Square.Retrofit2.ConverterMoshi then write my own (I had both earlier without issue), but if I remove the binding library I wrote for Retrofit (I think I would also need to remove Moshi, MoshiAdapter and Moshi Converter binding library to I think as there get included in the NuGet Square.Retrofit2.ConverterMoshi also?

Even after I remove all of these and only include the nuget I still get this issue:

You might want to try removing the projects from your solution. I think Unloading just keeps Visual Studio from loading them, they are still used when you build your solution.

@jpobst

This is all fixed now :) I ended up removing the following binding libraries: Retrofit, OkHttp3 and OkIO that I wrote as they now get included in the following nugets Square.OkHttp3 (has dependency to OkIO) and Square.Retrofit2.... however I reincluded the following binding libraries Moshi, MoshiAdapter and MoshiConverter.... I really have no idea why this became an issue when it worked perfected a week a go for quite while but these changes make sense now as I was previously using the nuget for retrofit but also had these in binding libraries I wrote earlier so this is probably better anyway!

[LeoJHarris]

@jpobst sorry one last thing I am just getting an issue with the MoshiAdapters binding library and wasn't experiencing this earlier (possibly introduced with the above changes and hit it as soon as I tried doing release build) but the error is:

4>  C:\SquareBindingLibrary.Android\MoshiAdapters\obj\Debug\generated\src\Com.Squareup.Moshi.Rfc3339DateJsonAdapter.cs(11,30,11,52): error CS0534: 'Rfc3339DateJsonAdapter' does not implement inherited abstract member 'JsonAdapter.ToJson(JsonWriter, Object)'

But looks like its already implemented here:

same here for ToJSON:

The actual jar file and method:

EDIT: I notice now the keyword override does not exist on the ToJson method

@jpobst

I resolved the above and debug the application builds fine but not in release mode would there be a reason for this?

I can probably resolve these the same way I did with the above but as the errors are similar but 68 errors to go through... at this stage unsure if I am fixing or breaking things

[LeoJHarris]

@jpobst Okay sorry for all the messages but I spent all day and finally got this working! My initial 68 errors went to about 20 errors after maybe doing a rebuild or fixing one issue that was causing other issues. That being said I fixed the error using the managedReturn, managedOverride and managedType. So it was a matter of adding the override and changing return types and param types to Object so weird I started getting these issues but if the project is working fine then I assume its fixes! I am convinced however this was working on debug and then I got to release config and boom the errors hit me!

[jpobst]

Yeah, looks like you hit covariant return types and managed to fix them. 😄

Glad you were able to get it all working!
