I downloaded the version of Unity you are using. Unity 2020.2.0f1, I can’t get it to build for android. Kept telling me the SDK was not installed. I definitely installed the SDK and JDK with the install. Went and downloaded the SDK and JDK and Java’s JDK. Pointed the folders towards them and now I’m getting a Gradle build failed. See the Console for details.
Again I am super frustrated. I had already deleted my previous project and started over to get the Unity version you were using because the Input System commands you were using don’t work on newer versions of unity and of course we’re using a deprecated version of Unity where Android building is completely messed up at this point. Oh I forgot to mention that I even downloaded Android Studio and tried to point unity at their SDK and it said it couldn’t find it.
