construct 2 is a cool game engine , which lets you create html5 game with drop and down editor and visual coding.
But exporting your game to android and ios version can be very tricky and at times very frustration (bugs , crash ,back screen , etc)
you need to use third party Services like cocoon.io and intel xdk to convert your html5 games into mobile app ie apk and IPA . which you can then published to App store.
both those service works great and speed up the game performance , but upload testing and build can take lots of times
You can create app file within your and own computer with the use of Cordova command-line
npm install -g Cordova.
create your project by typing project name bundle id and app name
Cordova create santa com.mobilezdeveloper.santa SantaRun
go into your project and add platform (android , ios, window , etc)
Cordova platform add android
open android studio and import your project
click ok to use Gradle wrapper
go to construct 2 > export > Cordova
open your exported file , copy all the file and paste in the www folder of your project and can test your project.
