Preparation

Even though I did not know a line of Android code, I knew that one could write an Android app in Java. I knew a lot of languages, but didn't know the frameworks for many of them, rendering my knowledge of most of them useless. Learning Android was a chance for me to make Java a useful language for me by getting into mobile app development.

Front End

I started with the XML, of course. The XML layout files were the markup, meaning they didn't really use logic. I made one activity (that's what Android calls a screen) a day, and in around 2 weeks, I had nearly imitated my mockup (except for a lot of the details within, for example, the task screen).

Back End

This was my first time, or so I thought, separating the back end from the front end. I wondered what voodoo magic developers used to create a REST API and an "external API endpoint" and I wanted to make one myself.

API Deployment

I went back and forth between writing new backend code and writing new frontend code for the remaining two months, except for one hiccup. I used Vercel, a great freemium hosting platform, for hosting my API and GoDaddy for the domain.

As I mentioned earlier, I wanted to employ techniques used by professional software developers. One of these was software development testing. I had done a course on EdX that covered how to write unit tests, so I wanted to make this a norm for my programming projects.
