I'm trying to create an app for Andriod and IOS, but i have no clue how to do the front-end and have a hard time deciding to use HTML5, CSS & JS or Objective objective C/Java.
I'ts going to be use network options, checkout-features, joined checkout-features. Maps api, facebook api.
I've got expierence in HTML5, CSS3, SASS, PHP and JS.
I've tried looking online, but i've still got no clue how to do the front-end for app.
I started developing native apps years ago. The last 2 years I've been using only hybrid possibilities. Designing and developing an app in HTML / CSS / JS is much easier and more efficiently.
I recommend taking a look at Phonegap, Ionic, Framework7. These are open source and there are already some templates.
