Major Announcements and their Impact on Android Development

It’s crucial for every Android developer to take into account these major announcements, for creating performance-packed, scalable and user-centric apps to cater custom business needs

Android Jetpack (Alpha version libraries)

Jetpack got a major update in the form of 11 Jetpack libraries that can make Android app development more fast and easy. Whereas earlier introduced Jetpack Compose is used to simplify UI development.

  • Camera X library enables Android app development company to build camera application or integrating the best camera functionality.
  • Lifecycle & LiveData KTX library can simplify how concurrency is tackled within Android Applications.
  • Benchmark library lets mobile apps company get the quickest ways of benchmarking their app code, whether it’s written in Java or Kotlin.
  • Security library implements the right security practices for Android apps. It can balance encryption properly with performance, especially for consumer applications.
  • ViewModel with SavedState module can remove boilerplate code and earn numerous advantages of using both SavedState and ViewModel. ViewPager2 actually provides a quite easier way of listening for page data changes

Android Jetpack (Beta library)

  • Developers can now tackle the complicated transition even without using coding via MotionLayout, which is a part of ConstraintLayout 2.0 that advocates for new optimizations and also the latest way of optimizing the app’s layout
  • Biometric library offers users a complete trustworthy experience with an app.
  • Jetpack Enterprise library lets your app avail an advantage of backward compatibility with a fully managed configuration.
  • Android for Cars libraries help users get a complete driver-optimized version of your app.
  • Jetpack Compose will be created with a couple of principles including Kotlin’s advantages, declarative for defining UI components, offering reusable blocks for creating custom widgets easily, compatible with existing appearance, material design and more.

New in Chrome and Web

Addressed by Ben Galbraith, Dion Almaer and others, this session at Google I/O 2019 majorly talked about certain improvements for web platforms, while primarily focused on three key goals such as Instant, Powerful and Safe

Impact on Web App Development

  • The app development company can now use Preload and Prefetch to help browser understand what to prioritize, when it comes to current page, to improve performance of the web apps.
  • Developers can improve overall user experience with Lazy Loading, which ensures loading only those images that users wish to see. It can automatically manage new images to load, when scrolled by users.
  • Google Search Console got a new speed report that helps developers get a full insight at the URL level. It helps them get aggregated details regarding how group of pages of apps can be improved further.

  • Google has announced to open up Duplex to the web, which developers can leverage to make PWA more powerful. For instance, users can easily make car rental reservation. All they need to say, help me find rental car through rental company’s and the app will pull up the site and make reservation automatically.
  • Google team has worked to build Performance Budgets directly into Lighthouse, after witnessing majority of well-known apps implemented Performance Budget within their development environment.
  • Developers can now make PWA more powerful by leveraging Web Perception Toolkit, Trusted Web Activities and ‘Install’ button in Chrome UI. Web Perception Toolkit lets developers easily integrate with device camera. Trusted Web Activities enable developers to integrate website content into Android Apps. Where as ‘Install’ button in Chrome UI improves discoverability of PWAs and prompts users to install it.
  • The new update at Google IO will also help developers to make PWAs more secure by letting users find details with transparency, regarding how sites actually deal with cookies. The google team is also planning to help developers in providing more privacy protection for users by limiting the cross-site cookies to HTTPS connections. The team is also planning to improve fingerprint option further.
  • Firebase team has expanded successfully the performance monitoring tool, which is set to web apps in beta.

Android Development Tools

Addressing the session at Google I/O 2019, Tor Norbye said, “We are not going to introduce any new tools and technologies for Android development this year.
