please help me!!!

 

me too

 

I found out that you have to downgrade to unity 2020 in order to get it to work since there seems to be a problem with grandle in the latest. now that im not a programmer i cant figure out on how to get it to work on latest version

 

More generally...

Android build not building:

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

If it does NOT build, then go fix your Unity installation, or your other tools, such as Android SDK, NDK, JDK, etc.

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 that subsystem.

 

It's because Unity developers forgot to include Tools folder
c:\Program Files\Unity\Hub\Editor\2021.3.6f1\Editor\Data\Tools\
I copied the Tools folder from another version of Unity there and everything works.

 

Had the same problem just now (word for word exact 3 errors) and fixed it. Cidonix answer didn't work for me as that path is not the same one present in the error, but it put me on the right track. For your case do what I did:

I created a "Tools" folder here:

C:\Program Files\Unity\Hub\Editor\2021.3.6f1\Editor\Data\PlaybackEngines\AndroidPlayer

I then copied the contents of this folder (containing GradleTemplates and a bunch of other stuff)

C:\Program Files\Unity\Hub\Editor\2021.3.6f1\Editor\Data\PlaybackEngines\AndroidPlayer\SDK\cmdline-tools\2.1

Into my newly created Tools folder and it worked since it can now found the correct files at the correct location it is looking for.

Try that - should fix it.

 

Can confirm the Unity Hub installer neglects to install the tools directory to this path:

c:\Program Files\Unity\Hub\Editor\2021.3.6f1\Editor\Data\Tools\

Copying over the directory from another recent Unity Editor installation will allow one to make Quest/Android builds again.

Hopefully Unity fixes the 2021.3.6f1 installer bug ASAP!

 

same, downloading 2021.3.3f with all android tools, then copying from it tools folder to 2021.3.6f fixed it

 

Awesome, that works fine - what a fix xD

 

I reported the bug to unity

 

Looks like this is now fixed with the recent 2021.3.7f1 release

 

damm u really helped me thank you man... holy S*** ppl are smart

 

Thanks a lot !!!
It worked.

 

Thanks a lot, it helped me!
I would like to switch to a new version of the Unity engine...
(This has been fixed in version 2021.3.8f1)

 

Life savior ! Thanks community !
And pls damn Unity, don't call it LTS if you engineers could mess up such simple things
