Android Dev Challenge: lift off with Jetpack Compose

Link copied to clipboard

Posted by The Jetpack Compose Team

Jetpack Compose is Android’s modern toolkit for building native UI. It enables you to quickly bring your app to life with less code, powerful tools, and intuitive Kotlin APIs. With the Beta of Jetpack Compose released today, this is the perfect time to learn Compose and get ready to adopt it. To help you get started with Jetpack Compose we are launching a new #AndroidDevChallenge!

For the next four weeks, the #AndroidDevChallenge will be launching a series of weekly challenges to help you build better apps faster with Jetpack Compose. Oriented around “lift off insights," each challenge focuses on a new area of Compose, from animations to Material Theming, composables to lists and more! Compete to win new prizes for each challenge, with over one thousand prizes to win including a Pixel 5. 1 The first challenge starts today!

The challenges

Every week brings a new challenge with its own rules and tasks. Every Wednesday starting today we’ll publish a blog post containing the full description of what you need to do and how long you have to complete the task. Each challenge will help you get familiar with the compose mental model and different Compose APIs - from basic Composables like Text and List, to state, animations and more.

Your solution to each challenge 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.

Week #1 - Puppy adoption app

Let’s start the #AndroidDevChallenge with a bang bark: build a puppy adoption app! The app should contain an overview screen that displays a list of puppies, and a detail screen showing each puppy's details. You have until March 2nd, 23:59 PST to submit your entry. 2

Your UI must be fully built in Compose. Your submission will only be judged based on your app’s UI layer. To help you with the implementation, check out the Compose documentation on layouts, lists, text and navigation. For some paws-on learning try out the Compose pathway, with codelabs covering several topics useful in completing this challenge.

Are you a 🐱rather than a 🐶 person? Submissions for any type of pet adoption app are welcomed.

We look forward to seeing what you build!

This week’s prize

Our first challenge kicks off with a prize that makes for the perfect sidekick as you’re flying through Compose: a limited edition trophy of our Jetpack Compose superhero, made of LEGO bricks. The first 500 people to successfully complete this challenge and submit their entry can add this trophy to their collection of Android figurines, showing off how you’re a winner for the first week’s #AndroidDevChallenge.

Week #1 prize: Jetpack Compose superhero
