Giving users more control over place

Android Q introduces the ART runtime which help apps start faster and consume less memory, without requiring any work and a few developments.

One thing that’s particularly sensitive is programs’ accessibility to location while the program isn’t in use (from the background). Android Q allows users to give apps permission to view their location never, only when the app is in use (operating ), or all of the time (when in the background).

We are expanding our efforts to have all apps take full advantage of the security and functionality features in the most recent edition of Android. Later this year, Google Play will need you to set your program’s targetSdkVersion to 28 (Android 9 Pie) in new programs and upgrades. In line with these modifications, Android Q will warn users using a dialog when they first run an app that targets a stage sooner than API degree 23 (Android Marshmallow). Following is a checklist of tools to help you migrate your app.

The network proposal APIs let programs surface preferred Wi-Fi networks to the user for connectivity. Programs initiate connections by providing a ranked list of programs and credentials as WifiNetworkSuggestions. When in range of those networks, the system will join based on performance.

Wi-Fi performance mode

For apps that perform their sound processing in C++, Android Q presents a native MIDI API to communicate with MIDI devices through the NDK. This API lets MIDI information to be retrieved inside a sound callback employing a non-blocking read. Give it a try using the sample program and source code here.

Starting in Android Q, apps can ask a Dynamic Depth image which consists of a JPEG, XMP metadata related to thickness related elements, along with a depth and optimism map embedded in precisely the exact same document on devices that promote support.

This allows media suppliers to stream high quality video content to Android apparatus with less bandwidth.

With significant privacy characteristics which will probably affect your programs, we recommend getting started with testing right away. Specifically, you will want to empower and test using Android Q storage changes place permission conditions, limitations on desktop app launch, and limitations on device identifiers. Watch the privacy documentation for details.

You can now request flexible Wi-Fi in Android Q by enabling high performance and low latency modes.

As the ecosystem evolves, Android is focused on helping users make the most of the latest innovations, while ensuring users’ privacy and security are always a top priority.

We’re also shifting the ecosystem toward readiness for apparatus. Later this year, Google Play will require 64-bit support in all apps. Keep in mind you’ll want to offer compliant versions of libraries or those SDKs if your app uses libraries or native SDKs. Watch the developer guide for information about the best way best to get ready.

To utilize the new performance styles, call WifiManager.WifiLock.createWifiLock() using WIFI_MODE_FULL_LOW_LATENCY or WIFI_MODE_FULL_HIGH_PERF. In these manners, the platform functions to meet with the requirement.

Camera, media, graphics

Dynamic thickness format for photos

By way of example, an app asking for a user’s location for food delivery makes sense and the user may want to grant the ability to accomplish this to it. But since the app may not require location outside of when it is currently being used, the user may not need to grant that access. Android Q now provides this level of control. Read the developer guide for details about the best way to accommodate your program to get this new controller. Look for developments to come in upcoming Betas. At precisely the same time, our objective is to be somewhat sensitive to always give developers as much notice and support as possible with those changes.

The MediaCodecInfo API presents an easier way to determine the video manufacturing capabilities of an Android apparatus. For any specific codec, you can obtain a list of supported sizes and frame rates utilizing VideoCodecCapabilities.getSupportedPerformancePoints(). This allows you to select the best high quality content to leave on any device that is particular.


We’ll expand the execution with performance optimizations, and OpenGL performance, bug fixes. Watch the docs for information on the present ANGLE service in Android, the way to utilize it, and our strategies moving forward. You are able to start testing with our first support by. Give it a try today!
If you’d like the newest fixes for Android Q related alterations, we recommend you utilize Android Studio 3.5 or higher.

Devices have opened up use-cases and some revolutionary experiences. To assist your programs to take advantage of those and other large-screen apparatus, we have made a number of improvements in Android Q, such as changes to onResume and onPause to encourage multi-resume and notify your program when it’s focus. We have also changed how the resizeableActivity exemplify feature functions, so you can manage how your app is displayed on foldable and large screens. To you begin building and testing on those new devices, we have been hard at work updating the Android Emulator to support multiple-display type shifting — more information coming soon!

Now you can also show key system settings right in the context of your program, through a new Settings Panel API, which benefit from the Slices feature that we introduced in Android 9 Pie.

The program should operate and look great, and handle the Android Q behavior changes for many apps properly. If you find problems, we advocate fixing them without changing your level. Have a peek at the migration guide for steps and a recommended timeline.

When a user would like to share content such as a photo with someone in another program, the procedure should be fast. With Sharing Shortcuts, which let users jump into another app to share content we’re making this faster and simpler in Android Q. Developers can print share targets that establish a particular action within their apps with articles attached, and these are shown to users at the share UI. Since they are published in advance, the share UI can load when launched.

In Android Q, we have expanded what your apps can perform with Android’s connectivity stack and additional new connectivity APIs.

Our purpose is to make Vulkan on Android a consistent and broadly supported developer API for images. We are working together with our device manufacturer partners to make Vulkan 1.1 a necessity on all 64-bit apparatus running Android Q and greater, and a recommendation for most 32-bit devices. This will help provide a uniform graphics API for games and programs to utilize.

Neural Networks API 1.2

In Android Q, we’re enabling new methods to entice users into your apps and streamlining the experience as they transition from different apps.

We’re bringing these changes to you early, which means you can get as much time as possible to prepare. We have worked hard to provide developers detailed advice up front, we recommend reviewing the detailed docs on the solitude changes and getting started with testing right away.

New approaches to engage customers

SDK throughout the trailer and we plan to upgrade the preview system images. We will have more attributes as the Beta program goes ahead to talk about.

We are also continuing to make improvements in ART itself. By way of instance, at Android Q we have optimized the Zygote process by transferring it to a security container and starting your program’s process sooner, so it’s ready to start instantly. We’re saving more information from the heap image, such as classes of the app, and using threading to load the image faster. Generational CC is more efficient as it collects young-generation objects individually, incurring much lower price as compared to full-heap GC, while nonetheless reclaiming a fantastic quantity of space. This makes garbage collection more efficient in terms of time and CPU, helping apps run on apparatus and reducing jank.

Security for programs

Android has been created at the middle with privacy and security. As Android has developed, we’ve added a wide range of features to protect consumers, like file-based encryption, OS controls requiring apps to request consent before accessing sensitive tools , locking down camera/mic desktop access, lockdown mode, encrypted backups, Google Play Shield (which scans over 50 billion apps a day to identify potentially harmful programs and remove them), plus even more. We’ve made even more enhancements to secure our users. A number of these enhancements are a part of our job in Project Strobe.

Upgrade your app’s targetSdkVersion into’Q’ as soon as possible. This lets you test your program with all the privacy and security attributes in Android Q, in addition to some other behaviour changes for apps targeting Q.

Explore the new features and APIs

It’s easy – it is possible to register here to acquire Android Q Beta updates over-the-air, on almost any Pixel device (and this year we are supporting three generations of Pixel — Pixel 3, Pixel 2, and even the original Pixel!) . Downloadable system graphics for those devices are also available. If you don’t possess a Pixel apparatus, the Android Emulator can be used by you, and get the emulator system images through the SDK Manager.

To empower more consistency for game and graphics programmers, we’re working towards a standard, updateable OpenGL driver for all devices assembled on Vulkan. In Android Q we’re adding experimental support for ANGLE along with Vulkan on Android devices. ANGLE is a graphics abstraction layer created for high performance OpenGL compatibility across implementations. During ANGLE, the many programs and games with OpenGL ES can benefit from the performance and stability of Vulkan and take advantage of a constant, vendor-independent execution of ES on Android devices. In Android Q, we’re likely to support OpenGL ES 2.0, together with ES 3.0 next on our roadmap.

In Android Q, the OS provides more control over apps access to shared documents to users. Users will have the ability to control programs’ accessibility to the Photos and Videos or the Audio collections through fresh runtime permissions. For Downloads, programs need to use the machine file picker, which allows the user. For programmers, there are adjustments to your apps can use places on external storage. Make sure to read the Scoped Storage changes for information.

We’re restricting access to device identifiers, such as device IMEI, serial number, and identifiers. Read the best practices that will help you choose the right identifiers for your use case, and see the facts here.

As always, your feedback is critical, therefore please let us know what you think — the earlier we hear from you, the more of your comments we can incorporate. When you find problems, please report them . We have different hotlists for filing platform issues, app compatibility problems , and third party SDK issues.

Since introducing the Neural Networks API (NNAPI) at 2017, we’ve continued to enlarge the amount of operations supported and enhance existing functionality. In Android Q, we’ve added 60 new ops such as ARGMAX, ARGMIN, LSTM that was quantized, alongside a range of performance optimisations. This lays the foundation for accelerating a greater range of versions — such as those for image segmentation and object detection. We are working with hardware vendors and popular machine learning frameworks such as TensorFlow to Boost and roll out service for NNAPI 1.2.

BiometricPrompt is our unified authentication frame to support biometrics at a platform level. For passive authentication methods like face we are extending support in Android Q, and adding explicit and implicit authentication flows. In the explicit stream, the consumer must confirm the transaction in the TEE. The implicit flow is designed for a alternative for transactions with authentication. The fallback for device credentials improved when needed.

The network link APIs make it easier to manage IoT devices over local Wi-Fi, for peer-to-peer functions like printing, downloading, or downloading. The platform handles the scanning itself also displays networks. The system sets up the connection automatically, when the user chooses.

Using Android Q, the OS helps customers have control over when apps can get location. When the program has asked you for permission as in prior versions of this OS, apps can get place, and you have granted it.

They capture thickness metadata for a variety of points in the image and apply a static blur into the image, and they discard the depth metadata.

It’s important to examine your apps for uses of non-SDK interfaces. Even if the APIs are exempted (grey-listed) at this time, it’s best to plan for the future and remove their use to decrease compatibility problems. For more details about the restrictions in Android Q, visit the developer guide.

We have also seen that users (and developers!) Get angry when an app requires over focus and suddenly jumps to the foreground. Android Q will prevent apps from launching a Task whilst at the background to reduce these interruptions. If your program is in the background and needs to find the user’s attention quickly — such as for incoming calls or alarms — you can utilize a high-priority notification and provide a full-screen intent. See the documentation to learn more.

Since Android Nougat, ART has offered Profile Guided Optimization (PGO), which rates app startup over time by identifying and precompiling frequently executed parts of your code. Profiles are being now delivered by Google Play together with APKs to assist with first app startup. These are anonymized, aggregate ART profiles that let ART parts of your app before it’s run, providing a significant jump to the optimization procedure. All apps are benefited by cloud-based profiles and they are already accessible to devices running Android P and higher.

If your app only needs to make peer-to-peer connections or suggest networks, check out the improved Wi-Fi APIs below — they simplify connections and don’t demand location consent.

Foldables and advanced new displays

Requesting a JPEG + Dynamic Depth picture makes it possible that you offer blurs and bokeh options . You can use the data to create 3D pictures or support AR photography. We’re making Dynamic Depth an open format for the ecosystem, and we are working together with our partners that are device-maker to ensure it is available across devices running Android Q and later.

New audio and video codecs

We’re releasing Beta 1 of Android Q for early adopters and a trailer SDK for programmers. You can begin using Beta 1 today by registering any Pixel device (including the first Pixel and Pixel XL, which we have extended assistance for by popular demand!) Please let us know what you believe ! Continue reading for a taste of what is in Android Q, and we’ll see you in Google I/O in May when we’ll have more to share.

Construction on top of privacy protections in Android

In addition to the randomized MAC addresses which Android Q supplies when linked to different Wi-Fi networks, we are adding new Wi-Fi benchmark support, WPA3 and Enhanced Open, to boost security for work and home networks as well as open/public networks.

Improved peer reviewed and net connectivity

A settings panel is a floating UI which you invoke from your app to show system configurations that users may need, such as web connectivity, NFC, and sound volume. There is no need settings as needed can be managed by users . To exhibit a preferences panel, simply fire an intent with a few of those new Settings.Panel activities .


The Sharing Shortcuts mechanism is comparable to how App Shortcuts works, so we’ve expanded the ShortcutInfo API to earn the integration of both features simpler. This new API is supported in the ShareTarget AndroidX library. This permits programs to use the new functionality, while allowing apparatus that are pre-Q to operate using Immediate Share. It is possible to find an early sample app with source code .

Settings Panels

Our benchmarks indicate that stable connections could be established up to 40% faster with TLS 1.3 compared to TLS 1.2. TLS 1.3 is allowed by default for all TLS connections. See the docs for specifics.

Compatibility through public APIs

We’re making further updates give command to users to ensure transparency, and secure data.

In Android Q we are restricting access to more non-SDK ports and asking you to use the people equivalents instead. To help you make the transition and also prevent your apps from breaking, we’re enabling the restrictions only when your app is targeting Android Q. We will keep on adding public choice APIs according to your requests; in most scenarios where there isn’t any public API that fulfills your use situation, please let us know.

Another thing most of us care about is ensuring that apps run as the OS changes and evolves. Apps utilizing APIs hazard crashes for emergency and users rollouts for programmers. In Android Q we are continuing our long-term attempt begun in Android P to move programs toward only using public APIs.

Vulkan anyplace

When you are prepared, dive into Android Q and find out about the new features and APIs you can use in your programs. Take a peek at the API diff report, the Android Q Beta API reference, and developer guides as a starting point. Additionally, on the Android Q Beta developer site, you will discover release notes and support tools for reporting issues.

In Android Q we refactored the Wi-Fi stack to boost privacy and functionality, but also to enhance common use-cases like managing IoT apparatus and indicating internet connections — without needing the location permission.
