Ultimate 12 months, Google used the Android Beta Program, which helps you to get early Android builds by the use of over-the-air updates on make a selection units. This 12 months, then again, Google isn’t making the primary preview to be had as a beta (you’ll want to manually flash your software). In different phrases, Android 11 isn’t in a position for early adopters to take a look at, simply builders.

If Google sticks to its standard cadence, the corporate will most likely open Android 11 trying out to extra telephones with the second one developer preview. The primary Android 11 developer preview is, then again, to be had on a pair extra telephones (8 Pixels versus six). Nonetheless, that’s a tiny slice of the over 2.Five billion per 30 days energetic Android units — the principle explanation why builders are keen to look what’s new for the platform within the first position.

With Android Q, Google talked up toughen for 5G and foldable units. The corporate is maintaining the ones going, whilst additionally emphasizing system finding out enhancements.

If you wish to have the fast model, listed below are the primary Android 11 developer preview highlights: 5G reviews, other people and conversations enhancements, Neural Networks API 1.three, privateness and safety features, Google Play Machine updates, app compatibility, connectivity, symbol and digicam enhancements, and occasional latency tweaks.

Developer Preview 1 options

Nonetheless now not happy? This is the longer model of the entire new APIs and contours (and there’s extra to return; that is simply the developer preview, in any case):

• Bandwidth estimator API: Google up to date this API for 5G to enable you take a look at the downstream/upstream bandwidth, with no need to ballot the community or compute your personal estimate. If the modem doesn’t supply toughen, the API makes a default estimation according to the present connection.

Symbol replica toughen could also be to be had in Chrome whilst symbol paste toughen will display up in Gboard’s clipboard.
• Neural Networks API (NNAPI) 1.three: Google is increasing the operations and controls for working computationally extensive operations for system finding out on Android units. High quality of Provider APIs toughen precedence and timeout for style execution and Reminiscence Area APIs cut back reminiscence copying and transformation for consecutive style execution. Quantization toughen has received signed integer uneven quantization, the place signed integers are used instead of floating level numbers to allow smaller fashions and quicker inference.
• One-time permission: For essentially the most delicate kinds of information — now not simply location but additionally for the software microphone and digicam — customers can now grant transient get entry to thru a one-time permission. This permission signifies that apps can get entry to the knowledge till the consumer strikes clear of the app, and so they will have to then request permission once more for the following get entry to.
• Scoped garage: Improvements together with opt-in uncooked dossier trail get entry to for media, up to date DocumentsUI, and batch edit operations in MediaStore.
• More secure Location Get admission to: Up to date Google Play Coverage to make certain that apps simplest request location permissions when really important.
• Biometrics: Expanded to fulfill the wishes of a much broader vary of units. BiometricPrompt now helps 3 authenticator varieties with other ranges of granularity — sturdy, susceptible, and software credential. The BiometricPrompt has been decoupled from the app’s Job lifecycle to enable you combine with quite a lot of app architectures, and to give a boost to the transaction UI.
• Platform hardening: Expanded use of compiler-based sanitizers in security-critical parts, together with BoundSan, IntSan, CFI, and Shadow-Name Stack. Google has additionally enabled heap pointer tagging for apps focused on Android 11 or upper, to lend a hand apps catch reminiscence problems in manufacturing. The crew used HWAsan to seek out and connect reminiscence mistakes — builders can now use HWAsan-enabled formula photographs to seek out such problems of their apps.
• Protected garage and sharing of information: Apps can now percentage information blobs simply and extra safely with different apps thru a BlobstoreManager. The Blob retailer is perfect to be used circumstances like sharing ML fashions amongst more than one apps for a similar consumer.
• Id credentials: Android 11 provides platform toughen for protected garage and retrieval of verifiable id paperwork, similar to ISO 18013-Five compliant Cellular Riding Licenses.
• Google Play Machine Updates: Mission Mainline has received 12 new updatable modules, for a complete of 22 modules. New modules come with a permissions module that standardizes consumer and developer get entry to to severe privateness controls on Android units, a media supplier module, and an NNAPI module that optimizes efficiency and promises constant APIs throughout units.
• Minimizing the affect of habits adjustments: Android 11 minimizes behavioral adjustments that might have an effect on apps through intently reviewing their affect and through making them opt-in, anyplace conceivable, till the developer units targetSdkVersion to Android 11.
• More uncomplicated trying out and debugging: Most of the breaking adjustments are toggleable. Builders can thus force-enable or disable the adjustments in my opinion from Developer choices or ADB. There’s thus not a want to trade targetSdkVersion or recompile apps for fundamental trying out.
• Up to date greylists: Up to date the lists of limited non-SDK interfaces.
• Dynamic useful resource loader: A Useful resource Loader framework in Android 11 so much sources and belongings dynamically at runtime.
