Developers like you have always played an important role in Android innovation. Over 10 years ago, when we first launched the Android SDK, we also announced the Android Developer Challenge to reward model apps and highlight new ways of solving user problems. As Android pushes the boundaries of machine learning, 5G, foldables, and more, developers continue to help shape these new frontiers. To celebrate this work, we revived the challenge in 2019, with a focus on “Helpful Innovation,” powered by on-device machine learning.
We received hundreds of creative projects, and at the end of last year, picked 10 winners who each combined a strong idea and a thirst to bring it to life. Since then, we’ve been working with those winners to help turn their ideas into reality. And today, we’re announcing the 10 winners. Some are still at the beginning of their journey but but their apps are now ready for you to download and try out! !

Making on-device machine learning more accessible, with ML Kit and TensorFlow Lite
Increasingly, machine learning is becoming a more accessible tool to developers with limited to no background in the technology. In fact, for most of the winners of the Android Developer Challenge, this was their first foray into machine learning. That’s thanks in part to two key offerings from Google, which bring on-device machine learning into reach for millions of developers around the world.
The first isML Kit. ML Kit brings Google’s on-device machine learning technologies to mobile app developers, so they can build customized and interactive experiences into their apps. This includes tools such as language translation, text recognition, object detection and more. Eskke, for instance, uses offline text recognition and barcode scanning from ML Kit so users can scan the QR code at a mobile money kiosk and quickly withdraw money. And MixPose uses ML Kit's forthcoming Pose detection API to detect each user’s yoga positions and movements, so teachers can provide feedback.
The other Google resource that many of the Android Dev Challenge winners used was TensorFlow Lite. This powerful machine learning framework can help run machine learning models on Android, iOS and IoT devices that would never normally be able to support them. Its set of tools can be used for all kinds of powerful neural network-related applications, from image detection to speech recognition, bringing the latest cutting-edge technology to the devices we carry around with us wherever we go. Trashly, for instance, uses a custom TensorFlow Lite model to report if an object is recyclable and how to recycle it.
Helpful innovation, such as the 10 winning apps in the Android Developer Challenge, has the potential to change the way we access, use, and interpret information, making it available when we need it, where we need it most. By working with these developers focused on helpful innovation, we hope to inspire the next wave of developers to unlock what’s possible with this new technology.
What’s next in Android Machine Learning week?
As we kick off the second week of #11WeeksOfAndroid, focused on Machine Learning, we will highlight new tools and resources available to Android developers. Here’s a taste of the rest of this week:
Tuesday - ML Kit, the turnkey ML SDK went through a major overhaul with its new on-device offering this month. Check out the substantial improvement in developer usability, CameraX support and where the platform is going next.
Wednesday - Custom Models. When prepackaged SDK doesn’t quite satisfy your need, tools from Android Studio, TensorFlow Lite and ML Kit might just be the answer. Aside from individual offerings, we will also highlight how they can be used together.
Thursday - ML design. Learn some best practices for making ML product decisions from the People + AI Guidebook. We will go behind the scenes of the Read Along app, an on-device ML app that helps grow universal literacy. Bring your whole team because everyone, including UXers, engineers, and product managers are invited!
On Tuesday and Wednesday, we will also have a “codelab of the day” so get your Android Studio 4.1 beta today, block off an hour in your schedule and take this ML journey with us!
*The apps presented here are the projects of the developers individually, and not Google.

Using machine learning to tackle Fall Armyworm
Take Nazirini Siraji. When she and a team of developers noticed a crop-pest threatening the livelihood of Ugandan farmers, they taught themselves TensorFlow to combat this pest. They collected training data from nearby fields in the form of images. With TensorFlow, they re-trained a MobileNet, a technique known as transfer learning and then used the TensorFlow Converter to generate a TensorFlow Lite FlatBuffer file which they deployed in an Android app. With the app, a farmer can snap a picture of their crop and the image frame is analysed to look for Fall armyworm damage. Depending on the results from this phase, a suggestion of a possible solution is given. It’s pretty cool!
Helping doctors detect respiratory diseases using machine learning
Tambua Health is helping doctors determine the likelihood of respiratory diseases by turning any smartphone into a powerful non-invasive screening tool. They developed an app using TensorFlow Litethat can help doctors analyze lung sounds for the presence of abnormal sounds like wheezes, crackles, stridor, and other adventitious sounds.
adidas uses machine learning to make the shopping experience easier
Even brands are tapping the power of machine learning. Take adidas, who recently launched a new “Bring It to Me” experience for their London store. Shoppers can use Visual Lookup to scan products on their phones while they are in the store, and the app lets them check stock and request their size without the need for queues. Under the hood, ML Kit is helping power the experience. It’s another way machine learning is helping users get things done more quickly.
The benefits of on-device machine learning
Running machine learning on a user’s device comes with a number of benefits. First, you reduce the amount of data you send to your server, enhancing user privacy. And because it runs on device, it can also work offline - perfect for inaccessible areas such as the middle of a rainforest, a desert or the London Underground. Last but not least, the most exciting aspect of running your model on device is low latency and this can enable all kinds of new user experiences. Machine learning is not just for automating tasks, it can work alongside your users and give them super powers too!
At Google, we offer a number of different technologies to help you take advantage of this:
ML Kit offers a turnkey SDK to help you tackle tasks with powerful Google Machine Learning models
There’s also the infrastructure of Firebase / Google Cloud, which can help you train on-device models using AutoML Vision Edge for specific model types or give you the raw processing power to train your own model
If you’ve got a great idea that can help users get things done, we want to hear from you! We’ll pick 10 concepts and provide expertise and guidance to those developers to help in their plans to bring their ideas to fruition. And once the app is ready, we’ll help showcase it in front of the billions of users on Google Play, through a collection and more. You can read more about all of the prizes here.
There’s still time to submit your idea before the December 2 deadline. We can’t wait to hear what you come up with, and to work with you on bringing helpful innovation powered by on-device machine learning to more and more users!
Developers like you have always played an important role in shaping the direction of Android, fueling the wave of Android innovation. It’s the reason that when we first launched the SDK for Android 10+ years ago, we simultaneously announced the Android Developer Challenge: a way to help reward model apps and show us what user problems you wanted to solve. As Android continues to push the boundaries into emerging areas like ML, 5G, foldables and more, we need your help to bring to life the consumer experiences that will define these new frontiers.
As we kick off this challenge, the first area we’ll be focusing on is On-Device Machine Learning. At Google, we’re big believers in how this new technology can open up a world of helpful innovation so you can get things done in ways you never thought possible. Take Live Captions: for the almost 500 million people who are deaf and hard of hearing, Live Captions bring content to life and is exactly the type of machine learning-powered innovation we expect to see more of someday, and with your help we can turn someday into today!
Bringing your idea to life in front of billions of eyes
Got an idea? Whether it’s still a concept or ready for users, tell us how you could use Google’s help, and how it supports the mission of using machine learning to help people get something done. Join the #AndroidDeveloperChallenge topic on GitHub, and share your idea as a repository under this topic. Don’t forget to come back here and officially submit your concept.
We’ll pick 10 concepts and provide expertise and guidance to those developers to help in their plans to bring their ideas to fruition. And once the app is ready, we’ll help showcase it in front of the billions of users on Google Play, through a collection and more. Here’s what those 10 developers will get:
