I've been looking for people with the same problem as me. I tried to follow But I can't solve this problem
I did before :
After I encountered a problem I have tried deleting and reinstalling Unity.
I have tried creating a new project. and copy some of the models.
I created an empty projectใ
I tried installing another unity version.
But there is no way to solve this problem...

Unity FileNotFoundException "launcherTemplate.gradle" when building for Android

When using Unity 2021.3.6f1 I get a an error saying launcherTemplate.gradle file cannot be found. I don't see it referenced in the project anywhere.
I tried using a custom gradle file, modify existing gradle files but nothing has done the trick so far.

It looks like it's related to Unity Hub not installing Android build tooling properly.
From https://forum.unity.com/threads/cant-build-quest-game.1307529/
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.

Xamarin.Forms does not compile an Android Project

I tried to delete bin and obj files but nothing, this problem only manifests in the Android project, while the IOS version works fine.
Env:
Mac OS Catalina
VS 8.9.1
Any hint?

Workaround is now added in prerelease.
https://learn.microsoft.com/en-us/visualstudio/releasenotes/vs2019-mac-preview-relnotes
Workaround:- In some cases, Android projects may fail to build with an error The Java SDK could not be found, please set the path to it in the Xamarin.Android SDKs settings panel. A workaround is to execute the following command in a Terminal:
mkdir -p ~/Library/Android/sdk

Looking at the developer community portal this is a bug introduced in v8.9.1. It also specifies a workaround: manually copy the Android SDK files from the default path (found in the settings screen, see below) to the hardcoded path in the error message. In your case /Users/giulioserra/Library/Android/sdk

A better way for me instead of copying the files is a symbolic link, because I use the Android sdk for multiple applications and users and it takes much disk space.
The symlink solution worked for me:
ln -s /Path/to/real/sdk /Path/from/error/message

Unity won't export for android

After upgrading unity from version 5.3.4 to 2018, can't publish.

What Unity version are you using ? this used to happen due to a Unity bug which has been resolved since then.
Try to migrate your project to Unity 2017.1 to see if that helps.
