If a foldable device is configured, the emulator now sends hinge angle sensors updates and posture changes to the guest. Existing foldable devices will now update hinge sensor angle and posture when the toolbar's fold or unfold buttons are pressed. Snapshots may also not be working add -no-snapshot to the command line. Added console commands to obtain the emulator AVD directory, discovery file path in the Studio-embedded use case, and path to snapshots:. Added a drop down item in cellular page to turn on and turn off meterdness support, this is a no-op for older system images that do not support the 5G meterdness toggle.
You can check the status of the corresponding issue in the Chrome issue tracker. This requires a cold boot of those emulators. This update includes support for running the emulator directly in Android Studio and virtual devices with Freeform Window Mode activated by default.
The Android Emulator can now be run directly in Android Studio. Use this feature to conserve screen real estate, to navigate quickly between the emulator and the editor window using hotkeys, and to organize your IDE and emulator workflow in a single application window.
This hardware profile requires a system image with Android 11 Developer Preview 3 or higher. Resizing freeform windows is currently broken due to issues transferring focus to the Window Manager. This will be addressed in a future Android 11 system image release.
If you were previously unable to use the Android Emulator because your app depended on ARM binaries, you can now use the Android 9 x86 system image or any Android 11 system image to run your app — it is no longer necessary to download a specific system image to run ARM binaries.
These Android 9 and Android 11 system images support ARM by default and provide dramatically improved performance when compared to those with full ARM emulation. If you are using Windows bit, you cannot upgrade to version This update continues our work on the Project Marble initiative that was announced at the Android Developer Summit in November The following sections describe the Project Marble improvements that are included with this update:.
Starting with version This option is automatically disabled whenever the emulator is restarted. If you are using the command line, you can also enable host audio using the -allow-host-audio option, and you can use the following ADB commands to turn host audio data on or off, respectively:.
You can use headless builds to help you set up the emulator for Docker and continuous integration CI workflows. On Linux, headless builds no longer include the pulseaudio or libX11 libraries.
The system-dependent shared libraries that are not packaged with the emulator has been reduced to the following list:. To address CPU usage, the emulator now runs the following ADB commands on a cold boot after it receives a boot complete signal:.
This update also includes the following general improvements that are part of the Project Marble initiative:. This update also includes the following general fixes that are part of the Project Marble initiative:. The emulator now includes hardware profiles for foldable devices. To use these new hardware profiles, you must be using Android Studio 3. When you run the emulator using one of these hardware profiles, you can fold and unfold the device using the fold and unfold actions in the emulator toolbar, console commands , or the following keyboard shortcuts:.
The emulator now includes AR macros that can help you test common AR actions. For example, you can use a macro to reset all the device's sensors to their default state. For more information, see Test common AR actions with macros. This support is still experimental and is mainly for developers who work on system images, drivers, and game engines.
Many extensions are still missing. You can experiment with these APIs by setting the following environment variables:. HAXM can sometimes fail to map Vulkan coherent memory to the guest and shuts down the emulator. This is addressed in an upcoming HAXM update. Our CI and remote desktop users have the following long-standing issues:. To address this, when running on a Linux machine, the emulator now serves a gRPC service. Once the service is started, gRPC commands can then be issued from clients.
The current set of commands allows both sending input events and receiving screenshots. These commands help address the following issues:. For a complete list of the commands that are available, see this protobuf. The emulator has been difficult to set up with Docker and other continuous integration CI workflows due to the implicit expectations of the system being able to support Qt along with its shared library dependencies among other issues.
As a first step to address this, we've introduced a variant of the emulator launcher with QEMU executables that does not depend on Qt. On Linux, there is still a link to libX11 , but we hope to remove that soon as well. To use the headless emulator, run the emulator from the command line as usual, but replace the emulator binary invocation with emulator-headless. For more information, see the A recent post on Reddit detailed how the guest Android OS would always be using the host microphone's audio, and thereby allowing "Ok Google" to work unexpectedly.
We're sorry about this and will work with the Android team to make sure hotword detection is disabled in the system image as well. During our Project Marble investigations, we've noticed that high CPU usage on the emulator generally falls into the following three categories:. We found that at random intervals, all apps installed get updated, even when the user is not logged in. You can mitigate this issue by disabling auto app updates in the Play Store app.
This is caused by hotword detection that constantly pings the host. You cannot mitigate this issue by disabling host audio input because the CPU cost is primarily caused by the time that it takes to travel to the guest from the host.
However, you can mitigate this issue by revoking microphone permissions from the Google app. The third source of high CPU usage is animations. We have found that by optimizing the graphics driver stack we can also reduce CPU usage even when the emulator is not idle. We will be rolling out graphics driver optimizations incrementally as part of Project Marble. These system images include improved memory usage for guest-side graphics drivers.
You can now launch multiple instances of the same AVD and run them concurrently. Instances that you launch after the first instance are read-only, and their changes to the guest virtual disk are discarded on exit. To run multiple instances of the same AVD at the same time, launch any instances after the first instance from the command line using the -read-only flag.
This feature is made possible by copying the QCOW2 files associated with the writable parts of the Android image. To help you manage disk space, we have also bundled the qemu-img command line tool to allow you to pre-commit QCOW2 files before launching multiple instances. This property means that the instances share much of their RAM in common. Use this feature to run tests that require multiple devices to run in parallel.
We appreciate your feedback on possible use cases that are part of your normal interactive or CI workflow. Please create or upvote issues in Issue Tracker. By pre-allocating and mapping guest RAM as a file, the emulator can now save Quickboot snapshots during runtime, instead of doing all of the work on exit. If you currently experience long save times when closing your emulators, enable this feature to improve your Quickboot performance.
By default, a Quickboot snapshot is saved on exit and loaded again every time, like suspending and waking a real device. Because Android guest RAM is now auto-saved by default, if you want to define a device state and repeatedly load from that state, you need to tell the emulator to discard changes after each session. You can do this in the following ways:. Snapshots that are taken and loaded through the Snapshots UI function as they did before, with no file mapping.
Because this is a large change to how Quickboot works, we would greatly appreciate your feedback on whether it improves Quickboot performance and what kind of issues you encounter when using it. When you start the emulator from a snapshot either using the -snapshot command line option, or launching from a snapshot in the AVD manager the emulator disables both auto-saving for Quickboot snapshots and saving Quickboot snapshots on exit.
This reduces the chances that the Quickboot snapshot will be unintentionally overwritten, and avoids slow fallback paths that do not use file-backed Quickboot snapshots. This update includes the following QEMU changes:. On Windows, more webcams are now supported because the emulator dynamically resizes the camera frames that are delivered from the webcam.
This feature also prevents errors in frame delivery from causing the emulator to hang. To address issues with running out of disk space on Play Store images, the emulator now automatically resizes the userdata partition to 6 GB when running with a fresh Play Store AVD.
We would like to mention HAXM 7. HAXM 7. Due to low usage and high maintenance costs, we are planning to deprecate the bit version of the Android Emulator that runs on Windows. We will roll out a transition plan before removal and end-of-life for the bit version of the Android Emulator. However, we are actively seeking any feedback or concerns with this future change.
Please let us know in Issue Tracker if you currently rely on the bit version of the Android Emulator that runs on Windows and tell us how we can best work with you going forward. Some users reported that the emulator has been running slow.
If your AVD's config. You can find the config. To help you diagnose these issues, we have added more informative error messages. You can enable these error messages by running the emulator from the command line using the -verbose flag.
You can now save multiple AVD snapshots for a given device configuration and choose which of the saved snapshots to load when you start the emulator. Starting with Android Studio 3. To accommodate this expansion of the snapshot features, we have added a Snapshots category to the Extended controls dialog. This new pane contains controls for saving and loading AVD snapshots, including the controls for saving and loading the quick-boot snapshot that had previously been in the Settings pane.
This update includes bug fixes and improved support for large amounts of RAM. This change should greatly decrease the time needed to load a snapshot. For details, see Configuring VM acceleration. The screen recording controls are in the Screen record tab of the Extended Controls window.
To begin screen recording, click the Start recording button in the Screen record tab. To stop recording, click Stop recording. Controls for playing and saving the recorded video are at the bottom of the Screen record tab. You can also record and save a screen recording from the emulator using the following command on the command line:.
Developing and testing augmented reality apps AR with ARCore is now even easier with the new virtual scene camera, which allows you to experiment with your AR experience within a virtual environment. For information on using the virtual scene camera in the emulator, see Run AR apps in Android Emulator. You can now load a Quick Boot snapshot without restarting the emulator. To load a snapshot, open the Extended Controls window to the Settings page and click the Load Now button. We have made many improvements to the loading and saving of snapshots to improve efficiency of resource usage and to minimize the time that each operation takes.

CoolMind CoolMind Thank you, it seems to be working with your workaround. I hope there will be no any incompatibilities. You know, currently I have more problems with emulators, than had before.
But probably it may be connected with moving avd folder to another disk. Awesome, thanks a lot for the detailed explanation. I don't get why Google makes this so confusing by showing Android Q available on the stable channel even though you need to switch to canary channel for some dependencies, that's ridiculous SimonNinon, agree with you! But I think, this is a chance for us to play with different combinations of SDK tools. Many developers never try to install unstable tools, so they can try to update at least the emulator.
You have to use the Android Studio Canary build to get an updated emulator. It provides the fastest performance for Android gaming, supports. Android SDK Platform-tools revision 24 or later. Swiftshader as a pure software renderer on the host. Initial IPV6 support. Voice assistant button for Car AVDs is now hidden. Reduced download size due to optimizing ffmpeg build. Fixed crash when closing the emulator with editable slider widgets active in the extended UI.
When running the emulator in -no-window mode and screenshots are repeatedly taken, the screenshots should now better follow the state of the device.
