How do I get Mobile IAP to work on Android?

From the Asset Store
An addon collection that provides native mobile features for C3 and C2 game application projects.
  • I am trying to get a non-consumable in app purchase working in C3 for Android and having zero luck.

    I have read the manual, looked at all the forums posts, and youtube videos I could find in order to figure this out, and I am still stuck.

    I have made a minimal project for testing the process, consisting of a few text objects and a button, and the Mobile IAP plugin.

    I exported from C3 to Android (Cordova), choosing a Cordova Project and I downloaded the .zip from the export results screen.

    I am on Windows 8.1

    Using Construct 3 release r131 stable

    I installed NodeJS v10, Cordova 8.1.2, JDK 8 64-bit, Gradle 5.1.1, Android Studio 3.2.1, Android SDK, android platform-27 and tools, set the environment variables ANDROID_HOME, JAVA_HOME, and the appropriate paths were added to the PATH.

    I unzipped the C3 android export file, and opened a command prompt to the directory.

    I then tried to run the "cordova prepare" command and I get the following:

    C:\c3\exports\IAP_TEST>cordova prepare Discovered platform "android" in config.xml or package.json. Adding it to the project Using cordova-fetch for cordova-androidqjn@~7.1.1 Adding android project...

Discovered plugin "cordova-plugin-whitelist" in config.xml. Adding it to the project Installing "cordova-plugin-whitelist" for android This plugin is only applicable for versions of cordova-android greater than 4.0. If you have a previous platform version, you do *not* need this plugin since the whitelist will be built in. Discovered plugin "cordova-plugin-file" in config.xml. Adding it to the project Installing "cordova-plugin-file" for android The Android Persistent storage location now defaults to "Internal". Please check this plugin's README to see if your application needs any c hanges in its config.xml. If this is a new application no changes are required. If this is an update to an existing application that did not specify an "AndroidPersistentFileLocation" you may need to add: "<preference name="AndroidPersistentFileLocation" value="Compatibility" />" to config.xml in order for the application to find previously stored files.

    Here is the c3p file (dropbox because I do not see a way to attach the file here)

    Here is a screenshot of the event sheet.

    Any help would be appreciated.
