For Intel XDK
onesignal-cordova-plugin instead if you NOT using Intel XDK.
This adds required Android dependencies needed by OneSignal. Use this plugin along with
onesignal-cordova-plugin-pgb-compat when building with Intel XDK.
Why this is required
This was created as the main branch of the OneSignal Cordova plugin
onesignal-cordova-plugin uses a gradle script which Intel XDK does not allow. Using older .jar Cordova projects for Google Play services and Android Support library were recommended in the past but they are not compatable with newer plugins that use .aar sytle gradle compile entires. This is due to duplicate Java classes being defined which creates Cordova build errors durning the dex step.
