PRE APP TALKS Last month i set a goal for myself. Making Android app in one week. But after i choose application context, I and my friend talk about code and UI design. We want to make a "Currency -Simple Converter" app. We looked Markets for other apps in same category, we realized nearly all of then have ugly UI, bad UX. I think a mobile app has to be simple as possible an easy to use for everyone. I always want to make simple, clean UI. So we draw some sketch and started a web search for how we can get exchange rate datas for FREE :) After this quick search, we choose to use Yahoo. In that pre coding section, we decide to make an experiment about app's language. I wanted to add as many as possible language options and see what happens :) I hoped coding will take maximum 10 hours. (Actually it takes 11-12 hours to finish coding, bug fixing, adding theme option, UI and UX adjustments) All process goes like this; FIND IDEA THINK ABOUT IT DESIGN UI AND
