Android Dev Challenge: Week 2 – Countdown timer

Posted by Florina Muntenescu, Developer Relations Engineer

3…2…1… Time for another challenge! Welcome to the second week of the #AndroidDevChallenge! We loved seeing your creative submissions in week #1 so we can’t wait to see what you’ll build in week #2. Here’s your challenge:

Week #2 – Countdown timer ⏲️

Create a working, single screen countdown timer. You have until March 9th, 23:59 PST to submit your entry.¹

Your UI must be fully built in Compose. To help you with the implementation, check out the Compose documentation on state and animation. For some hands-on learning try out the Compose pathway, with codelabs covering several topics useful for completing this challenge.

Your solution must be implemented in a GitHub repository. Make a copy of this Github repository template and follow the instructions in the README. The template contains a basic Hello World! in Compose and a continuous integration setup.

This week’s prize: a Compose poster pack!

Our second week’s prize is a work of art, where the Composing is a collaboration with you! The first 500 people to successfully complete this challenge will receive a Jetpack Compose poster and a set of Android pencils, your own stress relieving coloring experience. Plus, you’ll get a limited edition Jetpack Compose comic strip poster, charting how Team Jetpack saves the galaxy from bad UI.
