Google Inc. the second test version of the open mobile platform Android 11. Release of Android 11 in the third quarter of 2020. To evaluate the new capabilities of the platform program . Firmware builds for devices Pixel 2 / 2 XL, Pixel 3 / 3 XL, Pixel 3a / 3a XL, and Pixel 4 / 4 XL. An OTA update is available for those who installed the first test release.
Major changes compared to Android 11:
- Added 5G state API, allowing applications to quickly determine the connection through 5G in modes or .
- For devices with folding screens API to retrieve information from the angle sensor of the screen halves. With the new API, apps can determine the exact opening angle and adapt the output accordingly.
- The call screening API has been expanded with features to identify robocalls. For call screening apps, support for checking the status of incoming calls through to detect spoofing of caller ID, as well as returning the reason for call blocking and changing the contents of the system screen displayed after the call ends to mark the call as spam or add it to the address book.
- The Neural Networks API has been expanded, providing applications with capabilities to leverage hardware acceleration for machine learning systems. Support for the activation function , which helps reduce the training time of neural networks and improve the accuracy of certain tasks, for example, speeding up work with computer vision models based on . Added a Control operation that enables the creation of more advanced machine learning models that support branching and loops. An Asynchronous Command Queue API has been implemented to reduce latency when chaining small related models.
- Separate types of background services have been added for the camera and microphone, which will need to be requested if the application needs to access the camera and microphone while inactive.
- Support for migrating files from the old storage model to
isolating application files on external storage (for example, on an SD card). When using Scoped Storage, the application data is limited to a separate directory, and accessing shared collections of multimedia files requires specific permissions. management of cached files. - New APIs have been added for rendering application interface elements with the emergence of the on-screen keyboard to organize smoother animation by informing the application of changes at the frame level.
- An API for managing screen refresh rate, allowing certain games and applications to set a different refresh rate (for example, by default, Android uses a refresh rate of 60Hz, but some devices allow it to be increased to 90Hz).
- a mode for seamless operation continuation after an OTA firmware update that requires the device to be rebooted. The new mode allows applications to retain access to encrypted storage without the user needing to unlock the device after a reboot, meaning applications can immediately continue their functions and receive messages. For instance, automatic installation of an OTA update can be scheduled for nighttime and conducted without user involvement.
- The Android emulator has added support for simulating the operation of both front and rear cameras. The rear camera has implemented Camera2 API HW. with support for YUV processing and RAW capture mode.
The front camera has implemented with support for a logical camera (one logical device based on two physical devices with narrow and wide viewing angles).
