Emulator 30.0.6 is now available in the Canary and Dev channels. Changes:
  • Upgraded protobuf verison to 3.11.4
  • Added experimental car data replay feature for when running Android Auto Embedded system images to the car data page in the extended controls. The feature is flagged off and is called CarVhalReplay. To enable:
    • Launch the emulator from command line with -feature CarVhalReplay
    • Or, add "CarVhalReplay = on" to ~/.android/advancedFeatures.ini
    • More details
  • Fixed kernel version parsing issue when running aarch64 guest kernels.
  • Vulkan
    • Worked around issue that occurs on Windows NVIDIA GPUs when creating/destroying VkPipelineLayouts in multiple threads.
  • Improved support (fixes, performance improvements) for host-side video codecs. Requires a future Android R system image.

Windows performance

We've noticed that the emulator has been running much slower on some Windows 10 systems than others, while some versions of Windows 8.x and below seem unaffected. The issue seems to be due to a recently introduced mitigation for the Foreshadow (L1TF) security vulnerability: https://support.microsoft.com/en-us/help/4073119/protect-against-speculative-execution-side-channel-vulnerabilities-in

Disabling the L1TF mitigation via

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverride /t REG_DWORD /d 3 /f
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverrideMask /t REG_DWORD /d 3 /f

(and then rebooting) will restore performance to its previous state. However, we don't recommend this if you are using the emulator to run arbitrary untrusted code.

Emulator 30.0.5 is now available in all channels. This is primarily a bugfix release with no new features except to be compatible with future Android R Developer Previews. Changes relative to previous stable version, 30.0.0:
  • When using a host webcam on Linux (webcam0 and others), more webcam formats are supported.
  • When running with Android 11 system images, a new protocol is used for the camera that uses host coherent shared memory and async processing.
  • For the Linux emulator, if the user does not have permissions to use /dev/kvm, we now print more informative error messages.
  • Emulator can now be launched from an sshfs mount point.
  • Added support for host-side / hardware H.264 and VPx decode via combinations of ffmpeg, VideoToolbox on macOS, and CUDA if a NVIDIA GPU is used on the host. This requires a future Android 11 system image release.
  • Sensors are now supported through the gRPC channel.
  • Fixed issue in Hypervisor.framework backend where x86 AND/OR instructions were not properly emulated when in long mode.
  • ipv6 port forwarding with SLIRP is now supported as part of the QEMU command line options and QEMU monitor:
    • ipv6_hostfwd_add [hub_id name]|[netdev_id] [tcp|udp]:[hostaddr6]:hostport-[guestaddr6]:guestport
    • ipv6_hostfwd_remove [hub_id name]|[netdev_id] [tcp|udp]:[hostaddr6]:hostport
  • Fixed incorrect timestamps in some metrics sending.
  • WebRTC service now only activates frame sending when needed.
  • 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.
  • Added experimental support in the virtual sensors page for displaying the virtual framebuffer in various states of folding, available via starting the emulator with the environment variable ANDROID_EMU_ABSTRACT_DEVICE_VIEW=1. The "Fold" slider controls folding of the display at various hinge angles (Only vertical fold is supported currently):



Android Studio 4.1 Canary 4 is now available in the Canary and Dev channels.

If you have Android Studio set to receive updates on the Canary or Dev channel, you can get the update by choosing Help > Check for Updates (Android Studio > Check for Updates on macOS). Otherwise, you can download it here.


Native Memory Profiler

The Android Studio Memory Profiler now includes a Native Memory Profiler for apps deployed to physical devices running Android 10 or later. To learn more, see the release notes.

Use TensorFlow Lite models in Android Studio

ML Model Binding makes it easy for you to directly import .tflite model files and use them in your projects. Android Studio generates easy-to-use classes so you can run your model with less code and better type safety. For more information, see the release notes.

General fixes

This update includes fixes for the following public issues:

C++ Build
  • Issue #143411149: Syncing after any change to any Gradle file forces full rebuild of native code

Dependencies metadata

When building your app using Android Gradle plugin 4.0.0-beta02 and higher, the plugin includes metadata that describes the dependencies that are compiled into your app. When uploading your app, the Play Console inspects this metadata to provide you with the following benefits:
  • Get alerts for known issues with SDKs and dependencies your app uses
  • Receive actionable feedback to resolve those issues
The data is compressed, encrypted by a Google Play signing key, and stored in the signing block of your release app. However, you can inspect the metadata yourself in the local intermediate build files in the following directory: <project>/<module>/build/outputs/sdk-dependencies/release/sdkDependency.txt.

To learn more, see Dependencies metadata.
