After just over a month since the launch of beta 1, Google announced the release of the second beta version of Android 15 and from the changes compared to the first beta we can find improvements in multitasking on large screen devices, since Improved ability to work with multiple apps simultaneously on devices with large screens. Now, it is possible to add a taskbar to the screen to quickly switch between applications and set shortcuts to the most used programs.

Another of the changes that stands out in this second beta of Android 15 is the ability to define a separate private section with applications, which is only displayed after additional user authentication. Apps in this section are stored in a separate profile and are suspended when access is not unlocked. Additionally, when viewing the application list, the content of the private section is displayed in a separate block. Notifications and settings associated with these private apps are hidden when they are locked, and files created and downloaded with these apps are separate from the main profile.

In addition to that, An OpenGL ES implementation based on the ANGLE layer has been prepared which runs on top of the Vulkan graphics API, marked as the priority interface for interacting with the GPU. This improves compatibility and sometimes performance of OpenGL applications. ANGLE can be enabled via the “Enable ANGLE” option in the “Developer Options/Experimental” settings section.

They have also been made improvements to the photo selection interface to easily tag photos and videosrecently elected, facilitating media management. In addition, the possibility of establishing the user's preferred address in the configurator has been added, adapting the grammar to the addresses issued by the system.

Has Optimized the operation of background services to allow applications to remain active even when the user does not interact with them. Background services that perform data synchronization or media processing automatically stop after running for 6 hours, thus improving resource management.

On the other hand, the second beta of Android 15 presents the ability to use the dav1d library to decode video in AV1 format on devices without hardware acceleration support. This library, developed by participants of the VideoLAN and FFmpeg projects, aims to deliver high performance and quality in multithreaded mode. In tests, dav1d proved to be three times faster than previous software decoders. It will be available as an option for now, but will be included by default in future updates.

Of the other changes that stand out:

  • Support is now available for devices that use 16 KB memory pages, which can improve the performance of memory-intensive applications. This is achieved by rebuilding applications that use NDK libraries. Switching to 16 KB pages has been shown to reduce the startup time of certain programs, power consumption, and overall system startup time.
  • Apps now provide custom thumbnails instead of default placeholders.
  • By default, display is enabled at the system level when navigating using screen gestures.
  • Animations are used to inform the user of upcoming actions, such as swiping left to minimize the app and display the home screen.
  • Added support for the Matrix44 class to transform coordinates using a 4x4 matrix when manipulating 2D surfaces in 3D space.
  • Additionally, the clipShader function was added to overlay a clip with a specific shader, thus improving graphical manipulation.
  • The Health Connect store now supports new types of data for exercise and nutrition management, such as monitoring skin temperature and defining training plans.
  • Correct cropping of written text is guaranteed with fonts that reproduce handwritten text, improving readability and presentation.
