Major Announcements and their Impact on Android Development

Every Android developer must take into account these major announcements, for creating performance-packed, scalable and user-centric apps to cater to 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 faster and easier. Whereas earlier introduced Jetpack Compose is used to simplify UI development.

  • Camera X library enables Android app development companies to build powerful camera applications and integrate the best camera functionality.
  • Lifecycle & LiveData KTX library simplifies how concurrency is tackled within Android applications.
  • Benchmark library lets Android apps companies get the quickest ways of benchmarking their app code, whether it’s written in Java or Kotlin.
  • The Security library implements the right security practices for Android apps. It now balances encryption properly with performance, especially for consumer applications.
  • ViewModel with the SavedState module can remove boilerplate code and earn advantages of using both SavedState and ViewModel with common code. ViewPager2 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.
  • The Biometric library offers users a complete trustworthy experience with an app.
  • Jetpack Enterprise library lets your app avail advantage of backward compatibility with a fully managed configuration.
  • Android for Cars libraries helps you 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 companies can now use Preload and Prefetch to help browsers understand what to prioritize, when it comes to the current page, to improve the performance of the web apps.
  • Developers can improve overall user experience with Lazy Loading, which ensures loading only those images that users browse through. 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 a group of pages of apps can be improved further.
  • Android developers can use Paint Holding to look at the page that’s being loaded and also whether it responds quickly and enough. It can reduce the flash of white when a browser displays that the app page is loading.
  • Google has announced to open up Duplex to the web, which developers can leverage to make more powerful PWAs. For instance, users can easily make a car rental reservation. All they need to say, help me find a rental car through a rental company, and the app will pull up the site and make reservations automatically.
  • Google team has worked to build Performance Budgets directly into Lighthouse, after witnessing the 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 the ‘Install’ button in Chrome UI. Web Perception Toolkit lets developers easily integrate with the device camera. Trusted Web Activities enable developers to integrate website content into Android Apps. Whereas the ‘Install’ button in Chrome UI improves the 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 deal with cookies. The Google team is also planning to help developers in providing better privacy protection for users by limiting the cross-site cookies to HTTPS connections. The team is also planning to improve the 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. Since we have focused on your issues and worked hard to resolve them.” He focused mainly on issues such as System Health, Feature Polish, and Bug Backlog.

Impact on Android App Development

  • Google team has opened up opportunities for Android developers to improve the health of mobile apps with certain major areas of improvements such as UI freeze dashboard, registration infrastructure, out of memory exception dashboard, leak report, client-side heap analysis, automatic leak detection, etc.
  • Android app development will be more focused on Kotlin-first. Developers dealing with new projects have to write code in Kotlin, which will include new Jetpack APIs and then features.
  • Live Caption is an important highlight of Android Q. It uses Android Audio Framework APIs and will enable developers to build apps that can display live caption for video or audio files. Leveraging tools like live transcription lets developers create Android apps that can directly recognize any speech and display it as text.
  • Dark theme is another important improvement that developers can leverage while developing Android apps to easily use the functionality to their application. It has the potential to enable the dark mode when the battery saver-mode gets turned on.
  • To deal with bug backlog, Android developers can now make it easier by developing a complete infrastructure to catch bug.
