In October of 2021 we released the final unit of Android Basics in Kotlin, our free, self-paced programming course that makes Android development accessible to everyone. It teaches people with no programming experience how to build Android apps. Along the way, students learn the fundamentals of programming and the basics of the Kotlin programming language.
In response to feedback from educators and learners, we've continued to iterate on our course material, adding projects that allow you to apply learnings along with new topics that can prepare students for more advanced material.
With these updates, Android Basics in Kotlin now covers the key material covered in Android Kotlin Fundamentals, so we will be sunsetting the latter course. More advanced learners are encouraged to work through the Basics material, skipping sections that they are familiar with and moving straight to quizzes. Focusing on basics means that intermediate and advanced learners that might be missing a key concept will have what they need to succeed with this material. This also allows our team to focus on making sure our courseware continues to represent our most recent guidance. In addition to courseware, we're continuing to provide codelabs, code samples, documentation, and video content to serve learners at all levels.
Our team is hard at work on the next course that will teach people how to program Android applications using Jetpack Compose. We're looking forward to teaching Android’s modern toolkit for building native UI because of all the ways that it simplifies and accelerates Android UI development.
Taking the current course will teach you the fundamentals of app development, serving as a great starting point should you want to explore the existing Jetpack Compose Learning Pathway, or jump into the upcoming Android Basics with Compose course. You'll have a foundation that you can build on as you continue to explore the world of Android development. Both versions of Android Basics are planned to coexist, giving the option of learning Android with either UI toolkit.
Whether you’ve never built an app before but want to learn how, or just want to brush up on some of our latest best practices, check out the Android Basics in Kotlin course.

Welcome to #IamaGDE - a series of spotlights presenting Google Developer Experts (GDEs) from across the globe. Discover their stories, passions, and highlights of their community work.
Gaston Saillen started coding for fun, making apps for his friends. About seven years ago, he began working full-time as an Android developer for startups. He built a bunch of apps—and then someone gave him an idea for an app that has had a broad social impact in his local community. Now, he is a senior Android developer at Distillery.
After seven years of building apps for startups, Gaston visited a local food delivery truck to pick up dinner, and the server asked him, “Why don’t you do a food delivery app for the town, since you are an Android developer? We don’t have any food delivery apps here, but in the big city, there are tons of them.”
The food truck proprietor added that he was new in town and needed a tool to boost his sales. Gaston was up for the challenge and created a straightforward delivery app for local Cordoba restaurants he named Uh-Lala! Restaurants configure the app themselves, and there’s no app fee. “My plan was to deliver this service to this community and start making some progress on the technology that they use for delivery,” says Gaston. “And after that, a lot of other food delivery services started using the app.”
The base app is built similarly to food delivery apps for bigger companies. Gaston built it for Cordoba restaurants first, after several months of development, and it’s still the only food delivery app in town. When he released the app, it immediately got traction, with people placing orders. His friends joined, and the app expanded. “I’ve made a lot of apps as an Android engineer, but this is the first time I’ve made one that had such an impact on my community.”
He had to figure out how to deliver real-time notifications that food was ready for delivery. “That was a little tough at first, but then I got to know more about all the backend functions and everything, and that opened up a lot of new features.”
He also had to educate two groups of users: Restaurant owners need to know how to input their data into the app, and customers had to change their habit of using their phones for calls instead of apps.
Gaston says seeing people using the app is rewarding because he feels like he’s helping his community. “All of a sudden, nearby towns started using Uh-LaLa!, and I didn't expect it to grow that big, and it helped those communities.”
During the COVID-19 pandemic, many restaurants struggled to maintain their sales numbers. A local pub owner ran a promotion through Instagram to use the Uh-Lala! App for ten percent off, and their sales returned to pre-COVID levels. “That is a success story. They were really happy about the app.”
Gaston has been a GDE for seven years. When he was working on his last startup, he found himself regularly answering questions about Android development and Firebase on StackOverflow and creating developer content in the form of blog posts and YouTube videos. When he learned about the GDE program, it seemed like a perfect way to continue to contribute his Android development knowledge to an even broader developer community. Once he was selected, he continued writing blog posts and making videos—and now, they reach a broader audience.
“I created a course on Udemy that I keep updated, and I’m still writing the blog posts,” he says. “We also started the GDG here in Cordoba, and we try to have a new talk every month.”
Gaston enjoys the GDE community and sharing his ideas about Firebase and Android with other developers. He and several fellow Firebase developers started a WhatsApp group to chat about Firebase. “I enjoy being a Google Developer Expert because I can meet members of the community that do the same things that I do. It’s a really nice way to keep improving my skills and meet other people who also contribute and make videos and blogs about what I love: Android.”
The Android platform provides developers with state-of-the art tools to build apps for user. Firebase allows developers to accelerate and scale app development without managing infrastructure; release apps and monitor their performance and stability; and boost engagement with analytics, A/B testing, and messaging campaigns.
Gaston looks forward to developing Uh-La-La further and building more apps, like a coworking space reservation app that would show users the hours and locations of nearby coworking spaces and allow them to reserve a space at a certain time. He is also busy as an Android developer with Distillery.
“Keep moving forward. Any adversity that you will be having in your career will be part of your learning, so the more that you find problems and solve them, the more that you will learn and progress in your career.”

That’s a wrap! We’ve just finished a new MAD skills series on Gradle and Android Gradle plugin build APIs. In this series we shifted gears and took a look at how you can extend your build by using Gradle and brand new Android Gradle plugin APIs.
We covered how Gradle works, how you can configure the Android Gradle plugin, and learned which APIs to use to help customize your builds and keep your builds fast and efficient. If you missed this series or some of the episodes, here is a quick recap of what to expect.
Gradle is a general purpose build tool which can build specific project types by using plugins. Plugins introduce a way to configure the build and decide which tasks are needed to build that project. Gradle configures and executes these tasks in different phases. Understanding how the build phases work and how to configure the Android Gradle plugin can help you customize your build according to your project’s needs and keep build times efficient.
You can check out the following video or if you prefer, read the article.
Extending your build by writing your own plugin gives you a way to customize your build even further! Starting with version 7.0, Android Gradle Plugin now offers stable extension points for manipulating variant configuration and the produced build artifacts. In this episode we started with writing a custom task and used the new Variant API to initialize and modify properties of Variants.
You can find the same content in article form.
As we saw in previous episodes, keeping your config phase fast and resolving values lazily can help keep your builds efficient. Providers and Properties let you pass inputs and receive outputs from Gradle tasks lazily. In this episode we also take a look at the new Artifacts API to access and modify the app manifest.
Check out the article or the following video.
In the last episode in the series, we feature Alex Saveau, who maintains the Gradle Play Publisher and Version Orchestrator plugins. Alex shares a tip on using modern AGP and Gradle APIs to manipulate Android build artifacts.
To learn more, check out the following video.
Finally, we wrapped up this series with a live Q&A session where we answered your questions. If you missed the Q&A, make sure to check out the following recording.
If you are interested to learn more, make sure to check out the resources and the Gradle recipes repo linked below! See you in the next MAD Skills series.

Android 12 revamps a key feature for many Android users, App Widgets, making them more useful, beautiful, and discoverable (84% use at least 1 widget). Today, we’re making it even easier to build them by releasing the first alpha of Jetpack Glance, a new framework built on top of the Jetpack Compose runtime designed to make it faster and easier to build app widgets for the home screen and other surfaces.
We’d love you to give it a try and share your feedback!
Glance offers similar modern, declarative Kotlin APIs that you are used to with Jetpack Compose, helping you build beautiful, responsive app widgets with way less code.
Glance “Hello World” widget sample
class GreetingsWidget(private val name: String): GlanceAppWidget() { @Composable override fun Content() { Text(text = "Hello $name") } } class GreetingsWidgetReceiver : GlanceAppWidgetReceiver() { override val glanceAppWidget = GreetingsWidget("Glance") }
Glance provides a base-set of Composables to help build “glanceable” experiences. Starting today with app widget components but with more coming. Using the Jetpack Compose runtime, Glance can translate Composables into actual RemoteViews, and display them in an app widget.
Diagram: Glance structure
This means that Glance requires Compose to be enabled and depends on Runtime, Graphics, and Unit UI Compose layers, but it’s not directly interoperable with other existing Jetpack Compose UI elements. However, state or any other logic within your app can be shared to create a glanceable UI.
This initial release introduces the main APIs to enable you to build app widgets in addition to providing interoperability with existing RemoteViews.
Here’s an overview of what the library offers, at a glance:

We are working on bringing even more functionality with default theming, further Android Studio support, and more. Stay tuned for new releases.
Note: while the minSDK is 21, we are currently only supporting compatibility till SDK v23.
Check out the sample on GitHub for a quick start. Glance works with the latest stable Android Studio, although since Glance relies on Compose Runtime, follow the steps on the Jetpack Compose docs to set it up first.
In addition, for a more advanced showcase, checkout the demos in the AndroidX repository.
ResponsiveAppWidget.kt demo
The Alpha version is your opportunity to influence the APIs, so please share your feedback and let us know your experience!
Happy Composing with Glance!

As Android apps grow in size, it's important to design the code with an architecture in place to allow the app to scale, improve quality and robustness, and make it easier to test.
An app architecture defines the boundaries between parts of the app and the responsibilities each part should have. This favors the separation of concerns principle that enables the aforementioned benefits.
In response to community demand for up-to-date guidance on app architecture, we're launching a revamped guide to app architecture. This includes best practices and recommended architecture for building robust, high-quality apps. It also provides a page for each layer of the recommended architecture: UI, domain, and data layers. Within them, you'll find deep dives into more complex topics, such as how to handle UI events.
Each Android app should have at least two layers:
You can add an additional layer called the domain layer to simplify and reuse the interactions between the UI and data layers.
General diagram of a typical app architecture. The UI layer gets the application data from the optional domain layer, or the data layer, that exposes application data.
We have created a learning pathway to help you consume this content in order and in a trackable way. Don't miss the chance to learn all of this and get a badge as recognition!
If you’re a beginner, you should begin by understanding the benefits of having an app architecture and then follow these recommendations as a first approach to the topic. Intermediate and advanced developers can follow these recommendations and customize them to their needs. In fact, our research suggests that most professional developers are already using these best practices.
You might be wondering if you should update your existing architecture to follow this recommendation, and the answer is no… or wait… it's up to you. If your current architecture works for your team, you might want to stick with it. But you might also find patterns in our guides you can benefit from and incorporate into your app.
This is the first batch of documents we're releasing, with more to come in 2022. Help us make the guidance better! If you have any feedback on the current recommendations or if you want to see other architecture-related topics in them, let us know in our docs issue tracker.

Hello there,
Today we are kicking off Notes from Google Play, a new series where several times a year we celebrate your creativity and impact, and share key insights and best practices, to inspire you to be bolder, go further, and build even more innovative apps and games.
Purnima Kochikar addresses our goals behind the 'Notes from Google Play' series.
2021 continued to be a year of challenges and uncertainty, and you inspired us by your ability to turn obstacles into useful and joyful apps and services. Your apps helped over 2.5 billion people using Android devices learn, connect, relax, exercise, laugh, have fun, and so much more. As a result, developers making over 1M USD per month with Google Play’s billing or having 10 million monthly active users grew by 30% this year.
In this inaugural edition of Notes from Google Play we celebrate your creativity and resilience. A developer who exemplified these traits and deeply moved and inspired me and my team is Mohammed Kamara. Thank you, Mo for channeling deep personal loss to create a better world for women of color, providing affordable and customized healthcare through the app. We are humbled to play a small part in making your vision for InovCares a reality.
Mohamed Kamara, CEO and Founder of InovCares, tells the story behind his groundbreaking healthcare app.
A special shout out also goes to the winners of the Best of Google Play Awards and the Indie Games Festival. All of you inspire us to continue to work hard to evolve Play and Android to enable you to build great apps and successful businesses.
This focus on you and your success resulted in many impactful developments in 2021, including the evolution of our business model and new product features and tools. At Google Play we are focused on two key goals - helping you build and grow sustainable global businesses and investing in Android and Play platform features, tools, and ecosystems to enable you to build innovative apps and games.
As the mobile industry has matured, you have created app businesses that have varying needs, so we’ve designed multiple programs to support you. For example, we created the Play Media Experience Program to encourage Video, Audio, and Books developers to build great cross-device experiences, while enabling apps that support authors & musicians by discounting the service fee as low as 10%. A few months ago we announced a new fee structure to support the evolution of the subscriptions business model, allowing all subscription app developers to benefit from lower fees. Due to the innovative changes we announced this year, I’m thrilled to share that 99% of developers globally now qualify for a service fee of 15% or less. Thank you for your thoughtful feedback while we were designing these programs and your vocal support since the launch of the new fee structure.
We have also continued to invest in programs to help you reach, retain, and re-engage your users.
We are committed to empowering you to turn your creative ideas into excellent apps and have created tools and guidelines to help ensure your apps are of high quality. I invite you to pay attention to three key features/guidelines:
Trust and safety are the cornerstones of sustainable business success and key to user loyalty. This year, we continued to invest in platform features and policies that help you build safer apps and strengthen user trust. We also heard your feedback and have invested in educational tools and resources to help you anticipate and understand the new features and policies. The key highlights this year -
Nothing excites me more than finding and nurturing the next generation of talented developers and building local ecosystems around the world that address local needs. Earlier this year we announced a reduced service fee tier of 15% on the first $1M in annual earnings for all developers, helping us continue to foster innovation on Android/Play.
It has been truly humbling to see key influencers, stakeholders, and industry and government leaders co-invest with us in this effort. Our most successful developers invested personal time and energy to mentor, coach, and grow Indies through the Indie Games Accelerator. Government leaders partnered with us to support startup ecosystems in countries like Korea and India - the ChangGoo program in Korea has been created in partnership with Ministry of SMEs and Startups (MSS) and the Korea Institute of Startup & Entrepreneurship Development (KISED), whereas the Appscale Academy in India was established in partnership with the MeitY Startup Hub, an initiative of the Ministry of Electronics and Information Technology (MeitY). Thank you all for your commitment to innovation and the app ecosystem.
Get a snapshot view of Appscale Academy: our growth and development program for startups across India.
I have missed seeing you in person over the last two years. The challenges imposed by COVID-19 helped us find new ways to stay connected. Many of you participated in virtual sessions to learn about new market opportunities and engaged in thoughtful online discussions on topics as diverse as Future of Work, Diversity, Equity, and Inclusion, and Growth and Global expansion strategies. Some of you also told us that you are feeling some online event fatigue, so this year we also invested in content that you can consume at your own pace including thought leadership and best practices, and e-learning courses on Play Academy. We even launched our first certificate to help you get the most out of our store listing tools and features.
Until the next edition, from my team to yours, best wishes for the upcoming year. We hope you will always see Google Play as a partner to help you delight your users, expand your audience, and grow your business.
Happy Holidays.
Purnima Kochikar,
Vice President, Google Play Partnerships
