A new feature added to Chrome for Android in 2016 provided developers an ability to let users add their site to Home screen for fast and convenient access by using Android shortcut.
Since, these web apps like installed native apps don’t show up throughout Android, and developers been asking for web app to show up in the app drawer—Google is rolling out a new version of this experience in Chrome beta that will integrate Progressive Web App to Home screen much deeper than before. For example, “Progressive Web Apps will now appear in the app drawer section of the launcher and in Android Settings, and will be able to receive incoming intents from other apps,” writes Google.
When long pressesed their notifications, “will also reveal normal Android notification management controls rather than notification management controls for Chrome.”
Even more, Google says they’ll ensure this same mechanism for installing Progressive Web Apps are available to all browsers on Android.
The newest Chrome 57 beta channel release for Android, Chrome OS, Linux, Mac, and Windows brings features such as CSS Grid Layout, improved add to Home screen, and Media Session API.
CSS Grid Layout is now available providing developers to arbitrarily place web elements on a grid with full control over their flow, sizing behavior and responsiveness to fit current screen size.
If you’re not aware, “CSS Grid suuports a two-dimensional grid-based layout system, optimized for responsive user interface design. Elements within the grid can be specified to span multiple columns or rows. Elements positioned in a CSS grid can also be named, making layout code easier to understand.”
Improved add to Home screen as mentioned above, “will now make PWAs appear in the app drawer section of launcher and in Android Settings, and will be able to receive incoming intents from other apps.”
Media Session API let developers customize lock screen UI and notifications with media content. By providing “metadata to browser about the content being played, developers can create rich lock screen messaging with included information such as title, artist, album name, and artwork,” says Google. Additionally , “site is now able to respond to user actions taken on the notification itself, such as seeking or skipping.” See the full changelog under the post.
While on Android, a new Associate Android Developer Certification by Google, that was announced at I/O 2016, has certified over 322 Android developers spanning 61 countries.
“Google Certified Associate Android Developer certification allows developers to proven their competency and earned the title.” The certification process consists of a performance-based exam and an exit interview.
Here’s how this works? “The cost for certification is $149 USD, and this fee includes three exam attempts. After making payment, the exam will be available for download, and you have 48 hours to complete and submit it for grading.”
In the exam, “you’ll implement missing features and debug an Android app using Android Studio. Those who pass this exam, will undergo an exit interview and will be asked questions about your exam and you’ll need to demonstrate your knowledge of Associate Android Developer competencies.”
