Android 15 gets its second developer preview with updates to satellite functionality, audio recognition, and more

The Android development team has just announced the release of the second developer preview for Android 15. 

The satellite communication functionality has been updated with new UI elements to provide a better user experience. Apps can also now use ServiceState.isUsingNonTerrestrialNetwork() to detect when a device is connected via satellite, and there is also now support for sending and receiving messages through SMS/MMS or RCS applications over satellite. 

The NFC experience was also updated; Apps can now request a device go into a mode where they listen to NFC readers but don’t send a response. 

PdfRenderer APIs have also been updated with advanced features like rendering password-protected files, annotations, form editing, searching, and selection. The APIs have also moved to a different module where they can now be updated using Google Play system updates, allowing updates to be separated from the platform release.

Audio recognition was also improved, with more fine-tuned capabilities for automatic switching between languages. The hope is that this will cut down on dropped words when switching, which has been an issue since the feature was introduced in the previous version of Android. EXTRA_LANGUAGE_SWITCH_INITIAL_ACTIVE_DURATION_TIME_MILLIS keeps switching to the beginning of an audio session, and EXTRA_LANGUAGE_SWITCH_MATCH_SWITCHES lets developers limit the number of times the language is switched in a session. 

Other new developer features added in this preview release include:

  • Granular line break controls with TextView
  • Support for more precise IntentFilter resolution
  • Expanded OpenJDK API support
  • The ability to show applications on the cover screen of flippable devices
  • Screen record detection
  • The ability for apps to customize Do Not Disturb rules

For efficiency updates, the team released the ApplicationStartInfo API, which gives details on whether an app had been started by a broadcast, content provider, job, backup, boot complete, alarm, or activity. 

Other updates include improvements to the Stopped State function of the PackageManager, more detailed app size information, the introduction of the mediaProcessing Foreground Service type, and new SQLite APIs. 

This release also introduces several media improvements, such as the ability to control the HDR headroom for images, automatic adjustments to volume to compensate for differences in volume between media, and deprecation of the Virtualizer class. 

“Android continues to add features enabling your apps to take advantage of premium device hardware, including the latest telecommunications features, high-end media capabilities, dazzling displays, foldable/flippable form factors, and AI processing,” Dave Burke, VP of engineering for Android, wrote in a blog post.

Difference between Web Designer and Web Developer Neeraj Mishra The Crazy Programmer

Have you ever wondered about the distinctions between web developers’ and web designers’ duties and obligations? You’re not alone! Many people have trouble distinguishing between these two. Although they collaborate to publish new websites on the internet, web developers and web designers play very different roles. To put these job possibilities into perspective, consider the construction of a house. To create a vision for the house, including the visual components, the space planning and layout, the materials, and the overall appearance and sense of the space, you need an architect. That said, to translate an idea into a building, you need construction professionals to take those architectural drawings and put them into practice. Image Source In a similar vein, web development and design work together to create websites. Let’s examine the major responsibilities and distinctions between web developers and web designers. Let’s get going, shall we? What Does a Web Designer Do?

2022: The year of hybrid work

Remote work was once considered a luxury to many, but in 2020, it became a necessity for a large portion of the workforce, as the scary and unknown COVID-19 virus sickened and even took the lives of so many people around the world.  Some workers were able to thrive in a remote setting, while others felt isolated and struggled to keep up a balance between their work and home lives. Last year saw the availability of life-saving vaccines, so companies were able to start having the conversation about what to do next. Should they keep everyone remote? Should they go back to working in the office full time? Or should they do something in between? Enter hybrid work, which offers a mix of the two. A Fall 2021 study conducted by Google revealed that over 75% of survey respondents expect hybrid work to become a standard practice within their organization within the next three years.  Thus, two years after the world abruptly shifted to widespread adoption of remote work, we are declaring 20
