I've completed the challenge and published my first android app, Spender
In 30 hours over 30 days, you can go from a complete novice android developer to publishing an app on the Google Play Store.
So there you have it, my first app, done. Reactions from family and friends have been "Wow. Really? You're writing an app.. What does it do?". My response is "It won't make any money and its more about going through the process". I wanted to write any app rather than just thinking about writing an app.
