Hello, I am a Korean novice developer.
Everything was originally smooth, but suddenly an error appears on top, and no Android build or normal build.
That error continues to work even if you run an empty project.
I deleted and re-installed UNITY too, but I think it’s not a problem with the project but a problem of its own.
I’ve looked it up in other communities, but it’s hard to see the same things or the solution is not clearly written.
Sometimes just a reimport-all will fix things. Other times more drastic steps may be required.
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 (edited on August 23, 2023 to include Android SDK 33…):
