• Create a new file named cordova_plugins.js in the <path to project>/www folder if it does not exist.
• Edit cordova_plugins.js and add a reference to the plugin to automatically load it:

    cordova.define('cordova/plugin_list', function(require, exports, module) {
    module.exports = [

Common issues

If you have an issue, make sure that you can answer to theses questions:
Did you create your item in the Developer Console?
Is the id for your item the same in the Developer Console and in your app?
Is your item active?
Have you waited at least a few hours since you activated your item and uploaded your apk on the Developer Console?
Are you using a different Google account than your developer account to make the purchase?
Are you testing on a real device, rather than the emulator?
Are you using a signed apk?
Is the version code of your app the same as the one uploaded on the Developer Console?

If any of these questions is answered with a "no", you probably need to fix that.
