January 2017 Summaries

Increasing diversity and inclusion in the tech industry is essential for fostering innovation and supporting the global ecosystem. To aid this effort, Women Techmakers has partnered with Change Catalyst to create a comprehensive video series and guides designed to help build inclusive tech hubs, including incubators, community organizations, accelerators, and coworking spaces. These resources can be accessed on the Women Techmakers YouTube channel and the Change Catalyst website. Women Techmakers is a global program by Google that supports women in technology, and those interested in learning more or joining the membership program can visit their official website.

In January 2017, Google announced the acquisition of Fabric, a popular mobile development platform from Twitter, to enhance its Firebase platform. The integration aims to combine the strengths of both platforms to provide developers with a comprehensive suite of tools for building high-quality apps across iOS, Android, and the mobile web. Firebase, which had expanded significantly eight months prior, is focused on simplifying software development and freeing developers to innovate by improving core features like Firebase Analytics, Test Lab, and Cloud Messaging, as well as offering new tools for game developers. Fabric's renowned crash reporting tool, Crashlytics, is expected to become Firebase's main offering in this area, while Twitter will maintain the SMS authentication service, Digits, during the transition. This acquisition reflects Google's commitment to providing a seamless mobile app development experience, allowing developers to concentrate on creating innovative user experiences.

The Android Security team employs a multi-layered approach to enhance device security by identifying and mitigating potentially harmful apps (PHAs) through systems like Verify apps, which checks for PHAs and warns users, allowing them to uninstall such apps. A key metric used in this process is the Dead or Insecure (DOI) score, which evaluates the retention rate of devices after app downloads to detect suspicious apps with unusually low retention rates. This DOI score helps flag apps that may degrade the Android experience, such as those from malware families like Hummingbad, Ghost Push, and Gooligan, which can lead users to factory reset or abandon their devices. By using statistical methods such as the Z-score to identify apps with significant deviations in retention rates, the DOI metric works alongside other security measures to protect users and aid in the early detection of PHAs before they become widespread.

Google is enhancing the Accelerated Mobile Pages (AMP) format to improve loading speeds, particularly for users with slow network connections. Central to this effort is the Google AMP Cache, which brings content closer to users through smart caching, ensuring faster and more consistent page delivery. Recently, Google introduced two key optimizations: improved image delivery and better performance in bandwidth-constrained conditions. The image optimizations involve reducing invisible data, converting images to the WebP format, adding "srcset" attributes, and adjusting image quality based on network conditions, resulting in significant byte reductions without noticeable quality loss. Additionally, optimizations for slow networks include using lower quality images and optimizing external font loading, with these changes being gradually implemented in countries like Vietnam and Malaysia. Overall, these efforts aim to reduce data usage by 45% across optimizations, enhancing AMP experiences for users globally.

In 2017, developers were encouraged to enhance the quality of their mobile apps using Firebase's suite of tools, including Crash Reporting, Test Lab for Android, Remote Config, and Realtime Database. Firebase Crash Reporting allows developers to integrate easily into their apps to track and fix user-reported crashes, while Test Lab helps ensure app functionality across a range of devices by automating tests. Remote Config offers the ability to safely roll out new features incrementally and conduct user experiments, leveraging Firebase Analytics for better engagement insights. The Realtime Database provides a seamless user experience by delivering real-time data updates without manual refreshes, improving user satisfaction and app ratings. These tools collectively aim to boost app performance, user delight, and overall ratings, encouraging developers to adopt these practices for a successful year in app development.
