Android Developer ChallengeSource: Google

What you need to know

  • Google this week announced the winners of its Android Developer Challenge.
  • The developer competition was aimed at building Android apps using the power of machine learning.
  • The apps specifically use Google's TensorFlow Lite framework, which enables on-device machine learning on Android.

While you may not think about it much, machine learning powers some of the most compelling and most exciting new features in the world of tech; Google Assistant, Live Caption, and the amazing imaging capabilities of Pixel cameras, it's all thanks to machine learning. And as the technology become democratised and more accessible to developers, Google has made a big push toward empowering Android developers, in particular, to benefit from the advances it has made in the field.

To that end, the company has built TensorFlow Lite, a streamlined version of its famous machine learning framework that's designed for on-device inference, the same kind of technology that powers the new Google Assistant's fully local processing, and made it available to Android developers en masse.

To encourage their use of these new tools, the company last year announced the Android Developer Challenge, where it invited Android app makers to use machine learning in their apps to empower users to do everyday tasks more easily and more efficiently. This week, it announced the ten winners of the challenge, hailing all the way from Balochistan, Pakistan and Goma, DRC to San Francisco and Munich.

The top 10 projects, which are now available for download on the Play Store, are:
