Last month, our friends at Android launched the Android Developer Challenge, and asked you to submit your ideas focused on helpful innovation, powered by on-device machine learning.

ML Kit for Firebase helps power many of these experiences, including adidas’ new in-store shopping experience for their London store. Shoppers can 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.

If you’ve used ML Kit for Firebase to create a great user experience, or if you’ve got a great idea for how you might use it, submit your idea by December 2! You can also check out more examples on the Android Developers blog.
