Smells like you have a broken JDK or Gradle or perhaps even the Android SDK.

To isolate that, make an empty new Unity project and get it building for Android first. Don't try anything else until you can successfully build an empty project.

If that does NOT build, something went wrong with your Unity installation and you must fix that first,.

If that DOES build, then something is un-kosher in your project above.

 

Ok, I created and built a new project and it got the exact same error.

 

Excellent, safe to ignore your project and work through all the docs on setting up Unity properly to compile for Android. Always best to use the SDK, NDK, JDK and Gradle that comes with the specific version of Unity you are using.

 

Ok, i use 2020.1.3f1
Should I update unity too or what I have to do?

 

I mean, should I now investigate what exactly is wrong with the error or what exactly?

 

u should re install unity

 

Ok, thank you!
I installed a newer version and it works fine!

 

If we install a different version of unity and work it out on an existing project, won't it misbehave? please clarify my doubt here.

 

Hi,
you should make a duplicate of your project and then fix the errors. If everything done, you can do the same thing on your main project. Hope that helps. You should install a LTS version. Works the best for me!

 

i have the sane problem and i didnt find anything to past it

 

Same problem , I fixed that by a downgrade to a lower SDK version
