"Gradle Sync failed" with 'Google Inc.:Glass Development Kit Preview:19' not found

Question

I know it's been awhile for glass development, but I'm hoping someone out there has solved this problem recently because I'm at a lost. I'm trying to get a clean, base immersion activity to compile and run on Google Glass using Android Studio and gdk. But, I'm getting an error when trying to run the Hello World immersion activity with Android Studio.

Error:Module 'app': platform 'Google Inc.:Glass Development Kit Preview:19' not found.

This is with no changes to base code, just a clean creation of a module following the quickstart guide. I have the gdk from 19 installed from sdk 19, and am using build tools version 26. I've tried installing and reinstalling pretty much everything. I know that the glass develop kit (gdk) is installed:

$ ls ~/Library/Android/sdk/add-ons/addon-google_gdk-google-19/libs/
gdk.jar

Here is what sdkmanager says about what else is installed (Android studio shows the same tools in it's interface):

$ ./sdkmanager --list

This is the relevant part of my build.grandle file

android {
    compileSdkVersion "Google Inc.:Glass Development Kit Preview:19"
    buildToolsVersion "26.0.0"
    defaultConfig {
        applicationId "com.example.xxx.glasstest"
        minSdkVersion 19
        targetSdkVersion 26
        //...

}

I've also tried setting the sdk version all to 19 and 19.1.0 as in other posts, but nothing seems to work.

And, I'm running this on Mac OSX Sierra and Android studio version 2.3.3

I think this question is related but I did try that answer already (which was down voted, not by me ...) — Adam A.

Turns out the latest version of gradle is not compatable with building using the Glass Development Kit (gdk). To get it comepile, open the top level build.gradle, and change

dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'

    }

to (note the 3 turned into a 2 --- easy to miss!)

dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'
    }

Then in your application build script, you can use the latest build version and target SDK 19.

android {
    compileSdkVersion 'Google Inc.:Glass Development Kit Preview:19'
    buildToolsVersion '26.0.0'
    defaultConfig {
        applicationId "com.example.xxx.glasstest3"
        minSdkVersion 19
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

Now, my glass device is so old, I need to get that fancy new upgrade before I can still run the app.
