Android Developers Blog: Introducing Android Q Beta

Posted by Dave Burke, VP of Engineering

In 2019, versatile advancement is more grounded than at any other time, with new innovations from 5G to edge to edge shows and even foldable screens. Android is directly at the focal point of this development cycle, and gratitude to the wide biological system of accomplices crosswise over billions of gadgets, Android’s helping push the limits of equipment and programming conveying new encounters and abilities to clients.

As the portable biological community advances, Android is centered around helping clients exploit the most recent developments, while ensuring clients’ security and protection are dependably a top need. Expanding over endeavors like Google Play Protect and runtime authorizations, Android Q brings some of extra security and security highlights for clients, just as upgrades for foldables, new APIs for network, new media codecs and camera abilities, NNAPI expansions, Vulkan 1.1 help, quicker application startup, and the sky is the limit from there.

Today we’re discharging Beta 1 of Android Q for early adopters and a see SDK for engineers. You can begin with Beta 1 today by enlisting any Pixel gadget (counting the first Pixel and Pixel XL, which we’ve broadened support for by famous interest!) Please told us what you think! Peruse on for a sample of what’s in Android Q, and we’ll see you at Google I/O in May when we’ll have considerably more to share.

Expanding over security insurances in Android

Android was structured with security and protection at the middle. As Android has developed, we’ve included a wide scope of highlights to ensure clients, similar to document based encryption, OS controls requiring applications to demand authorization before getting to delicate assets, securing camera/mic foundation get to, lockdown mode, scrambled reinforcements, Google Play Protect (which look over 50 billion applications every day to distinguish conceivably destructive applications and expel them), and substantially more. In Android Q, we’ve made significantly more improvements to secure our clients. A considerable lot of these improvements are a piece of our work in Project Strobe.

Giving clients more authority over area

With Android Q, the OS enables clients to have more authority over when applications can get area. As in earlier forms of the OS, applications can just get area once the application has approached you for authorization, and you have allowed it.

One thing that is especially delicate is applications’ entrance to area while the application isn’t being used (out of sight). Android Q empowers clients to give applications consent to see their area never, just when the application is being used (running), or constantly (when out of sight).

For instance, an application requesting a client’s area for sustenance conveyance bodes well and the client might need to allow it the capacity to do that. Yet, since the application may not require area outside of when it’s presently being used, the client might not have any desire to concede that get to. Android Q currently offers this more prominent dimension of control. Peruse the engineer direct for subtleties on the best way to adjust your application for this new control. Search for more client driven upgrades to come in up and coming Betas. In the meantime, we will probably be delicate to dependably give designers however much notice and backing as could be expected with these changes.

More security insurances in Android Q

Past changes to area, we’re making further updates to guarantee straightforwardness, give clients control, and secure individual information.

In Android Q, the OS gives clients much more command over applications, controlling access to shared records. Clients will almost certainly control applications’ entrance to the Photos and Videos or the Audio accumulations by means of new runtime authorizations. For Downloads, applications must utilize the framework record picker, which enables the client to choose which Download documents the application can get to. For engineers, there are changes to how your applications can utilize shared zones on outer capacity. Make a point to peruse the Scoped Storage changes for subtleties.

We’ve likewise observed that clients (and engineers!) get resentful when an application out of the blue bounces into the forefront and assumes control over core interest. To diminish these interferences, Android Q will keep applications from propelling an Activity while out of sight. In the event that your application is out of sight and needs to stand out enough to be noticed rapidly -, for example, for approaching calls or alerts – you can utilize a high-need warning and give a full-screen purpose. See the documentation for more data.

We’re constraining access to non-resettable gadget identifiers, including gadget IMEI, sequential number, and comparable identifiers. Peruse the prescribed procedures to enable you to pick the correct identifiers for your utilization case, and see the subtleties here. We’re likewise randomizing the gadget’s MAC address when associated with various Wi-Fi organizes as a matter of course – a setting that was discretionary in Android 9 Pie.

We are conveying these progressions to you early, so you can have however much time as could be expected to get ready. We’ve additionally endeavored to give designers itemized data in advance, we suggest auditing the point by point docs on the protection changes and beginning with testing immediately.

Better approaches to draw in clients

In Android Q, we’re empowering better approaches to bring clients into your applications and streamlining the experience as they change from different applications.

Foldables and imaginative new screens

Foldable gadgets have opened up some imaginative encounters and use-cases. To help your applications to exploit these and other extensive screen gadgets, we’ve made various enhancements in Android Q, including changes to onResume and onPause to help multi-continue and tell your application when it has center. We’ve likewise changed how the resizeableActivity show quality functions, to enable you to oversee how your application is shown on foldable and huge screens. To you begin building and testing on these new gadgets, we’ve been working diligently refreshing the Android Emulator to help numerous showcase type exchanging – more subtleties not far off!

Sharing alternate routes

At the point when a client needs to share content like a photograph with somebody in another application, the procedure ought to be quick. In Android Q we’re making this speedier and simpler with Sharing Shortcuts, which let clients bounce straightforwardly into another application to share content. Designers can distribute share focuses on that dispatch a particular action in their applications with substance joined, and these are appeared to clients in the offer UI. Since they’re distributed ahead of time, the offer UI can stack in a split second when propelled.

The Sharing Shortcuts component is like how App Shortcuts functions, so we’ve extended the ShortcutInfo API to make the joining of the two highlights simpler. This new API is additionally bolstered in the new ShareTarget AndroidX library. This permits applications to utilize the new usefulness, while permitting pre-Q gadgets to work utilizing Direct Share. You can locate an early example application with source code here.

Settings Panels

You can now additionally demonstrate key framework settings legitimately with regards to your application, through another Settings Panel API, which exploits the Slices highlight that we presented in Android 9 Pie.

A settings board is a skimming UI that you conjure from your application to indicate framework settings that clients may require, for example, web network, NFC, and sound volume. For instance, a program could show a board with availability settings like Airplane Mode, Wi-Fi (counting close-by systems), and Mobile Data. There’s no compelling reason to leave the application; clients can oversee settings as required from the board. To show a settings board, simply fire an aim with one of the new Settings.Panel activities.

Availability

In Android Q, we’ve expanded what your applications can do with Android’s network stack and included new availability APIs.

Network authorizations, protection, and security

The greater part of our APIs for checking systems as of now require COARSE area consent, yet in Android Q, for Bluetooth, Cellular and Wi-Fi, we’re expanding the security around those APIs by requiring the FINE area authorization. On the off chance that your application just needs to make shared associations or recommend systems, look at the improved Wi-Fi APIs underneath – they disentangle associations and don’t require area consent.

Notwithstanding the randomized MAC tends to that Android Q gives when associated with various Wi-Fi systems, we’re including new Wi-Fi standard help, WPA3 and Enhanced Open, to improve security for home and work arranges just as open/open systems.

Improved distributed and web availability

In Android Q we refactored the Wi-Fi stack to improve security and execution, yet in addition to improve normal use-cases like overseeing IoT gadgets and recommending web associations – without requiring the area consent.

The system association APIs make it simpler to oversee IoT gadgets over neighborhood Wi-Fi, for shared capacities like designing, downloading, or printing. Applications start association demands in a roundabout way by determining favored SSIDs and BSSIDs as WiFiNetworkSpecifiers. The stage handles the Wi-Fi checking itself and showcases coordinating systems in a Wi-Fi Picker. At the point when the client picks, the stage sets up the association naturally.

The system proposal APIs let applications surface favored Wi-Fi systems to the client for web availability. Applications start associations in a roundabout way by giving a positioned rundown of systems and accreditations as WifiNetworkSuggestions. The stage will consistently interface dependent on past execution when in scope of those systems.

Wi-Fi execution mode

You would now be able to demand versatile Wi-Fi in Android Q by empowering superior and low dormancy modes. These will be of extraordinary advantage where low inertness is essential to the client experience, for example, continuous gaming, dynamic voice calls, and comparable use-cases.

To utilize the new execution modes, call WifiManager.WifiLock.createWifiLock() with WIFI_MODE_FULL_LOW_LATENCY or WIFI_MODE_FULL_HIGH_PERF. In these modes, the stage works with the gadget firmware to meet the necessity with least power utilization.
