Google company second test version of the open mobile platform Android 11. Release of Android 11 in the third quarter of 2020. To evaluate new platform features program . Firmware builds for Pixel 2/2 XL, Pixel 3/3 XL, Pixel 3a/3a XL and Pixel 4/4 XL devices. An OTA update has been provided for those who have installed the first test release.
Major changes compared to Android 11:
- Added 5G state API, allowing the application to quickly determine the connection via 5G in modes or .
- For devices with foldable screens API for getting information from the screen halves angle sensor. With the help of the new API, applications can determine the exact opening angle and adapt the output accordingly.
- The API for checking calls has been expanded with features for detecting auto-calls. For applications filtering calls, support for checking the status of an incoming call via for falsified caller ID, and return the reason for blocking the call and change the contents of the system screen displayed after the end of the call to mark the call as spam or add to the address book.
- The Neural Networks API has been expanded, providing applications with the ability to use hardware acceleration for machine learning systems. Added support for activation function , which allows to reduce the training time of the neural network and improve the accuracy of certain tasks, for example, to speed up work with computer vision models based on . A Control operation has been added to allow you to create more advanced machine learning models that support branches and loops. The Asynchronous Command Queue API has been implemented to reduce delays when running through a chain of small related models.
- Added separate types of background services for the camera and microphone, which will need to be requested if the application needs to access the camera and microphone while inactive.
- Added support for migrating files from the old storage model to the vault
, which isolates application files on an external storage device (such as an SD card). With Scoped Storage, application data is limited to a specific directory, and access to shared media collections requires separate permissions. management of cached files. - Added new APIs for displaying application interface elements with the appearance of an on-screen keyboard to organize smoother output animation by informing the application about changes at the individual frame level.
- An API for controlling the refresh rate of the screen, which allows you to set a different refresh rate for windows of certain games and applications (for example, Android uses a refresh rate of 60Hz by default, but some devices allow you to increase it to 90Hz).
- the mode of seamless continuation of work after installing an OTA firmware update that requires a reboot of the device. The new mode allows applications to retain access to encrypted storage without the user having to unlock the device after a reboot, i.e. applications can immediately continue to perform their functions and receive messages. For example, automatic installation of an OTA update can be scheduled at night and carried out without user intervention.
- The Android emulator has added support for simulating the operation of the front and rear cameras. Camera2 API HW implemented for the rear camera with support for YUV processing and capture in RAW mode.
Level implemented for the front camera with logical camera support (one logical device based on two physical devices with a narrow and wide viewing angle).
