    I'm getting the AmbiguousMatchException spam too, but it's about AndroidResolver.

    I'm getting the same error in 2021.2.0a19 and 2021.2.0a20 as well, which prevents me from testing the Apple Silicon version with my main project.
    Are there any workarounds for this?

    Hi everybody,

    If you're affected by these errors after upgrading, it would be much appreciated if you could submit a bug report with a minimal reproduction project attached so we can investigate.

    Bug reported under case number 1343192.
    This may be as well something for Google to fix, as this SDK does all kinds of funny things after importing, but it certainly was working fine in earlier versions of Unity.

    Probably, but so far I don't even know what change causes this bug. I couldn't find anything good in the patch notes.

    The problem is with the Google Jar Resolver.
    Any package that depends on it, will throw that error (basically everything).

    To reproduce just import the Google Jar Resolver for unity. Or import the latest Facebook Unity Sdk. Or Import the latest Google Mobile sdk for Unity.

    Basically, just import anything interesting on android and the editor will stop working XD

    Welps, hope they fixed this soon. Android dev without Jar Resolver is a hard no.

    Yeah I'm surprised the dev team doesn't load any project during alpha testing that uses Jar Resolver. It's basically impossible if you do any serious dev. It's like testing Unity but not adding cameras.

    Is there any temporary solution/workaround to this for now? I really like 2021.2 and don't wanna downgrade just for this. And yes I do serious projects.

    No, there is none. The only solution is to download the google jar resolver source code, modify it yourself and recompile with it. Not fun.

    Hi all! The problem seems to be that we added a new overload to the GetApplicationIdentifier method that the google jar resolver was accessing through reflection, causing the Ambiguous match error.

    A quick look at their code suggests that they already fixed it. Hopefully that could help you!

    Hello!

    Found workaround:

    1. You need to download latest release from here: https://github.com/googlesamples/unity-jar-resolver/releases (1.2.166 + unity 2021.2.0b works fine)
    2. You need to replace binary files from folder: MyProject/Assets/PlayServicesResolver/.. with files from downloaded archive (/unity-jar-resolver-1.2.166/exploded/Assets/PlayServicesResolver/Editor/..)
    3. Enjoy :)

    Installing the latest External Dependency Manager (v1.2.166) and running a Force Resolve seems to fix the issue for me. (Unity version: 2021.2.0b14)

    Pro tip:     If you are getting a Java SDK issue, Go to Unity Preferences > External Tools > Uncheck then Re-check the "JDK installed with Unity".

    I was about to necro to ask for help, but I thought I would post my solution instead lol

    I wasn't making an Android game, so it was very confusing to my as to why I was getting this error. Turns out, I needed to download the external dependency manager
    And then SWITCH to Android, then force resolve, then switch back to WebGL(or whatever you're building to). This error is so strange, i was getting it from the Facebook SDK.

    You can always download the latest copy of External Dependency Manager aka Unity Jar Resolver from this link.
