Emulator 30.0.6 Canary, Windows performance

Friday, March 27, 2020

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.

Emulator 30.0.5 Stable

Wednesday, March 25, 2020

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):
