SDK Tools Not Unzipping Properly

[KnightRiderGuy]

I’ve been trying to follow this tutorial here:

Learn game development w/ Unity | Courses & tutorials in game design, VR,...

On how to build an app for Android devices. The tutorial was going fine up until I got to the part where you download and install the SDK tools
It says in the tutorial to download:

• Download the Android SDK Tools (also referred to on the site as “the command line tools”), rather than the full download of Android Studio.

Which I did, only when I open up the folder and double click on the "Android: file

I do NOT get the pop up window they say I should all I get instead is a terminal window that reads an error?

Can someone please help me out as to why this is happening? I followed every step exactly as the tutorial laid out, the project file downloaded and installed just fine but just getting nowhere with the SDK tool

I even tried downloading Android studio and in unity pointing the external tools folder address to the SDK address in Android studio:
/Users/michaelknight/Library/Android/sdk
And it tells me in the unity console that it’s wrong!! WTF??

If I try and do a build I get this BS:

The Unity console just spits out these errors:

Error:Invalid command android

UnityEditor.HostView:OnGUI()

And

ommandInvokationFailure: Unable to list target platforms. Please make sure the android sdk path is correct. See the Console for more details.
