Abstract

You want to introduce a dark theme throughout your app and you think it should be easy enough. However, once you dive into it, you realize it’s not that straight-forward. It’s easy to get lost with the turns you have to take to make it work.
Adding theming capability to an existing application involves a lot of thought process. Not only the existing UI has to be modified, a lot of design work is also needed. This involves keeping in sync with design team and working with tools of trade such as Sketch and achieving more automation with internal tools.
This talk will be focussed on how we can develop a system to make our app theme-able using a set of component libraries and a few xml tricks. We’ll go through various phases of theming which involves colours, icons and images inside the app and also on how to deal with the nightmare of making it work in older versions of Android.
We’ll also see challenges in implementing the same especially in a large application spread across multiple teams and how to maintain and test these components.
