Google has just introduced an Android 11 trial version, in which various changes and novelties are presented that Google has in mind for the stable version of Android 11, which is expected to arrive during the last months of the year.
This previous version Android 11 It is prepared for some devices, which are the following: Pixel 2/2 XL, Pixel 3/3 XL, Pixel 3a / 3a XL and Pixel 4/4 XL. While for other devices that update by OTA, it is expected that they can test Android 11 in May.
Main news of Android 11
Of the main novelties that stand out in the announcement of this release, it is mentioned that for Android Emulator the experimental ability to run 32-bit and 64-bit application code has been added compiled for the ARM architecture, surrounded by the Android 11 system image created for the x86_64 architecture running on the emulator.
Another of the changes that stand out is the expanded support for the 5G mobile standard, which provides higher bandwidth and less latency. Applications that create a large network load and perform actions such as watching streaming video in 4K quality and download game assets in high resolution can now work not only when connected via Wi-Fi, but also when working via a mobile network operator's network.
To simplify the adaptation of applications with respect to 5G communication channels, the dynamic measurement API has been extended, which is used to verify if the connection is charged for traffic and if it is possible to transfer large amounts of data through it. This API now covers cellular networks and allows you to determine the connection to a provider that provides a truly unlimited rate when connecting over 5G.
Moreover support for new "pinhole" and "waterfall" screen types is also mentioned. Applications can now determine the presence of additional visible and blind areas on these screens using the standard screen clipping API. To cover the side faces and organize the interaction in the areas near the edges of the "waterfall" screens, new calls are proposed in the API.
Wifi suggestion API was improved y allows the application (network connection manager) influence algorithm to choose preferred wireless networks by transmitting a ranked list of networks, and also taking into account additional metrics when choosing a network, such as information about the bandwidth and quality of the communication channel during the last connection.
Added the ability to manage wireless networks that support the Hotspot 2.0 standard (Passpoint), including accounting for user profile expiration and the ability to use self-signed certificates in profiles.
It has been realized Changes to Simplify Migration of Applications to Scoped Storage, which allows you to isolate application files on an external drive (for example, on an SD card). When using Scoped Storage, the application data is limited to a separate directory and access to shared collections of media files requires separate permissions. Android 11 implements support for optional media access mode via full file paths, updated the DocumentsUI API, and added the ability to perform batch operations in the MediaStore.
Enhanced ability to use biometric sensors for authentication. The BiometricPrompt API, which offers a universal dialog for biometric authentication, has added support for three types of authenticators: trusted, weak, and device credentials.
BiometricPrompt integration simplified with various application architectures, not limited to the use of the Activity class.
To simplify testing for compatibility of applications with Android 11, the interface of «Developer Options »and the adb utility provide settings to enable and disable capabilities that affect compatibility. Gray lists of restricted software interfaces that are not provided in the SDK have been updated.
