What's new in Beta 2?

Privateness options for assessments and feedback

As we shared it throughout the beta 1, we’re investing closely in privateness safety in Android Q, along with the work we’ve got performed in earlier releases. Our objectives are to enhance transparency, give customers extra management, and additional safe private knowledge on the platform and functions. We all know that to attain these objectives, we should collaborate with you, our software builders. We perceive that supporting these options can also be an funding for you. We are going to do all the pieces attainable to attenuate the affect in your functions.

For options like Scoped Storage, we share our plans as quickly as attainable to present you extra time to check and provides us suggestions. To generate extra normal feedback, we’ve got additionally enabled Scoped Storage for brand spanking new software installations in Beta 2 so as to extra simply see what’s affected.

With Scoped Storage, functions can use their personal sandbox with out permission, however they want new permissions to entry shared collections of photographs, movies, and sound. Functions that use recordsdata in shared collections (for instance, picture and video galleries, selectors, media navigation, and doc storage) might behave in a different way underneath Restricted Storage.

We suggest that you simply get began rapidly with Scoped Storage – the Developer's Information comprises detailed data on managing key use circumstances. For testing, make certain to allow Scoped Storage in your software with the assistance of the adb command.

We admire the superb feedback you will have already given us. It is a worthwhile assist for the event of this characteristic.

Bubbles: a brand new option to do many issues directly

In Android Q, we add a platform assist for bubbles, a brand new approach for customers to multitask and get again in contact along with your apps.

The bubbles will enable customers to carry out a number of duties concurrently they transfer from one exercise to the opposite.

Bubbles assist customers prioritize data and act in depth in one other software, whereas sustaining their present context. Additionally they enable customers to take with them the performance of an app once they swap from one exercise to a different on their gadget.

Bubbles are nice for messaging as a result of they permit customers to maintain essential conversations at their fingertips. Additionally they present a handy view of present duties and updates, reminiscent of cellphone calls or arrival instances. They will present fast entry to a conveyable consumer interface, reminiscent of notes or translations, and may also be visible reminders of duties.

We created bubbles above the Android notification system to offer builders with a well-known and simple to make use of API. To ship a balloon through a notification, you need to add a BubbleMetadata by calling setBubbleMetadata. Within the metadata, you’ll be able to point out that the exercise is displayed as content material within the balloon, with an icon (disabled in Beta 2) and the related individual.

We’re simply beginning to use bubbles, however strive them out and inform us what you assume. You’ll find an instance of implementation right here.

Foldable emulator

Because the ecosystem evolves quickly to foldable units, new use circumstances are opening up in your functions to make the most of these new screens. With Beta 2, you’ll be able to create collapsible units with enhanced assist for the Android Q platform, together with a brand new collapsible gadget emulator, accessible as an Android digital gadget in Android Studio three.5 accessible within the canary diffusion channel.

7.three "foldable AVD switches between folded and unfolded states

On the platform facet, we’ve got made various enhancements in onResume and onPause to assist a number of resumes and to inform your app when it’s energetic.

You may learn extra within the Developer's Information

To arrange a runtime atmosphere in your software, now you can configure a collapsible emulator as a digital gadget (AVD) in Android Studio. The Foldable AVD is a reference gadget that lets you check normal configurations, behaviors, and circumstances as they are going to be utilized by our gadget producers companions. To make sure compatibility, the AVD complies with CTS / GTS necessities and CDD compliant fashions. It helps runtime configuration modifications, a number of resumes, and new resizeableActivity behaviors.

Use the canary model of Android Studio three.5 to create a collapsible digital gadget that helps considered one of two configurations: 7.three "(four.6" folded) and eight "(6.6" folded) with Beta 2. In every configuration, the emulator controls the display screen to set off the fold / unfold, change the orientation and fast actions.

Android Studio – AVD Supervisor: Foldable Gadget Configuration

Strive at this time your collapsible emulator software by downloading the canary model of Android Studio three.5 and configuring a collapsible AVD file utilizing the Android Q Beta 2 system picture.

Improved sharing sheet

After the preliminary shortcut sharing APIs for Beta 1, now you can preview shared content material by offering an additional EXTRA_TITLE for the aim of the title or by setting the clipData of intent for a thumbnail picture.
