Resolved UnityPlayerActivity.java uses or overrides a deprecated API

Whenever I try to build I get this error

I have tried every solution on this post https://forum.unity.com/threads/unityplayeractivity-java-uses-or-overrides-a-deprecated-api.875770/ but none of them have worked. This error appeared at random after I unimported an asset from the asset store that I was sure I wasn't using. Also even if I restore the entire game from a backup, it still gives me the error.

 

How to troubleshoot build failures:

First, make a blank project with a single blank scene and prove that it builds successfully.

If the blank project does NOT build, go fix your Unity installation or your other tools, such as Android SDK, NDK, JDK, etc. It may even be necessary to change to a different version of Unity3D. It is generally best to stay with LTS versions of Unity3D.

Until you can build a blank project to the target platform, don't fiddle with anything else.

Once you can build a blank project, now bisect the problem by bringing over parts of your current project and building it one subsystem at a time, perhaps stubbing things out that might trigger compiler errors.

Most often things that prevent building are third-party libraries such as Firebase.

Once you identify the subsystem, go to the documentation for it and make sure you are doing it correctly.

It may also be helpful to work through a tutorial or two for whatever subsystem is making the build fail.

Android build not building:

Recently (circa July 2022) there have been reports of Unity's installer failing to install the Android Tools.

Here was how I brought up Unity2020.3.41 and the Android SDK 31 on October 30, 2022:

Thank you for responding. I tried building on an empty project and got a different error than last time, but I simply tried building again and the error went away somehow. I then tried building on my main game and it also somehow worked with no errors. No idea how.
