Improving Accessibility in the Android Ecosystem




Posted by Ian Stoba, Program Manager, Accessibility Engineering




With billions of Android devices in use around the world and millions of apps available on the Play Store, it might seem difficult to drive change across the entire ecosystem, but the Accessibility Developer Infrastructure team is doing just that.



Every time a developer uploads an APK or app bundle to the open or closed tracks, Play tests this upload on various device models running different versions of Android and generates a pre-launch report to inform the developer of issues.



One year ago, the team added accessibility suggestions to the report based on industry best practices and Google’s own experience. These tests check for common issues that can make an app harder to use by people with disabilities. For example, they check that buttons are large enough to be comfortable for people to press, and that text has enough contrast with the background to be easier to read.



Since launching in July 2018, more than 3.8 million apps have been tested and over 171 million suggestions have been made to improve accessibility. Along with each suggestion, the developer gets detailed information about how to implement it. Every developer, from a one-person startup to a large enterprise, can benefit from the accessibility suggestions in the pre-launch report.



We are already seeing the real-world impact of these efforts. This year at Google I/O, the number of developers signing up for in-person accessibility consultations was four times the number from 2018. Googlers staffing these sessions reported that the developers had specific questions that were often based on the suggestions from the pre-launch report. The focused questions allowed the Googlers to give more actionable recommendations. These developers found that improving accessibility isn't just the right thing to do, it also makes good business sense by increasing the potential market for their apps.



Accessibility tests in the pre-launch report are just one way Google is raising awareness about accessibility in the global developer community. We partnered with Udacity to create a free online course about web accessibility, released our Accessibility Scanner for Android on the Play Store, and published iOS Accessibility Scanner on GitHub, allowing iOS developers to easily instrument apps to accessibility tests. Together, these efforts support Google's mission to organize the world's information and make it universally accessible and useful.

Posted by Oli Gaymond, Product Manager Android Machine Learning On-Device Machine Learning enables cutting edge features to run locally without transmitting data to a server. Processing the data on-device enables lower latency, can improve privacy and allows features to work without connectivity. Achieving the best performance and power efficiency requires taking advantage of all available hardware. Android Neural Networks API 1.3 The Android Neural Networks API (NNAPI) is designed for running computationally intensive operations for machine learning on Android devices. It provides a single set of APIs to benefit from available hardware accelerators including GPUs, DSPs and NPUs. In Android 11, we released Neural Networks API 1.3 adding support for Quality of Service APIs, Memory Domains and expanded quantization support. This release builds on the comprehensive support for over 100 operations, floating point and quantized data types and hardware implementations from partners acro

Posted by Stephanie Cuthbertson, Director, Product Management Android 11 is here! Today we’re pushing the source to the Android Open Source Project (AOSP) and officially releasing the newest version of Android. We built Android 11 with a focus on three themes: a People -centric approach to communication, Controls to let users quickly get to and control all of their smart devices, and Privacy to give users more ways to control how data on devices is shared. Read more in our Keyword post . For developers, Android 11 has a ton of new capabilities. You’ll want to check out conversation notifications, device and media controls, one-time permissions, enhanced 5G support, IME transitions, and so much more. To help you work and develop faster, we also added new tools like compatibility toggles, ADB incremental installs, app exit reasons API, data access auditing API, Kotlin nullability annotations, and many others. We worked to make Android 11 a great release for you, and we can’t wait to se

Posted by Erica Hanson , Global Program Manager, Google Developer Student Clubs Google Developer Student Clubs , a program of university based community groups for students interested in Google developer technologies, recently started hosting study groups called Android Study Jams . The goal? Learn Android app development through hands-on codelabs in an online curriculum provided by Google. There are two tracks: one for students who are new to programming, and one for those who already have experience. Interested in participating? Facilitator materials are available for anyone to host Android Study Jams in their community - take a look and get to building. Google Developer Student Clubs are dedicated to helping students learn programming together, among peers, in a fun and interactive setting. While over 50 thousand students from all over the world have participated in these Android workshops, we wanted to highlight the exciting work from groups in Indonesia, Turkey, and Nigeria. F
