You shouldn't rely on those services. Instead you should try building your own apk's using the cordova command line tool.
Here is a tutorial I've made on the topic : https://www.scirra.com/tutorials/9432/h ... ng-cordova
It is all about the config.xml file, which holds all the configuration settings of your game and the plugins that will be downloaded by the cordova cli to be used in your game.
By default, C2 adds a couple of lines to the file so that cordova installs the webview plugin alongside the file and http plugins.
Do a search on how to include cordova plugins in the config.xml.
