Emulator 30.0.18 Canary

Friday, June 19, 2020

Emulator 30.0.18 is now available in the Canary and Dev channels.
Changes:

Embedded Emulator:

Fixed issue where uppercase characters were delivered as lower case characters in the emulator.

Fixed loading console token from a unicode path in windows.

Fixed SO_REUSEPORT error message on linux.

Updated ANGLE shader translator to keep up with upstream ANGLE. This fixed an issue around memory corruption when translating and constant-folding OpenGL ES shaders that used non-square matrices. The shader translator is now a separate shared library, libshadertranslator.dll.

Added console commands to obtain the emulator AVD directory, discovery file path in the Studio-embedded use case, and path to snapshots:

adb emu avd path # Obtains path to AVD directory

adb emu avd discoverypath # Obtains path to discovery file

adb emu avd snapshotspath # Obtains path to snapshots folder

adb emu avd snapshotpath <snapshotName> # Obtains path to the folder that stores the snapshot for the snapshot with name <snapshotName>

On macOS, SSE 4.1 and 4.2 are now available from inside the Android guest.

Emulator 30.0.17 Canary

Friday, June 12, 2020

Emulator 30.0.17 is now available in the Canary and Dev channels. Changes:

Graphics

More debug info has been added to WGL initialization on Windows in order to trace failures.
Fixed an issue on Vulkan initialization on some GPU drivers, where certain 1.1 device functions were not found.

Media

CUDA VPx decode is now properly supported, if CUDA VPx decode is available in hardware.

Added better support for detecting remote sessions on Windows.

Radio

Added a drop down item in Extended Controls > Cellular to toggle simulation of metered connections, such as for 5G use cases. This requires the latest R system image and is a no-op on previous API levels.

Added console command to control

gsm meter on
gsm meter off

Fixed GPX/KML route playback to follow timestamps.

Fixed bouncing icon on launch for macOS.

Fixed a snapshot corruption issue when sending snapshot commands through gRPC, as well as when pressing the snapshot save button in Android Studio embedded emulator.

Foldables: Configurable hinges and 3D preview
Added the ability to configure hinges for foldable devices along with a 3D preview in Extended Controls > Virtual Sensors. Future system images will be sensitive to the hinge configuration and adapt to a particular set of hinges. Up to 3 hinges can be specified.
Example: Create a Pixel 2 XL AVD and add the following lines to ~/.android/avd/avdName.avd/config.ini:
hw.sensor.hinge = yes
hw.sensor.hinge.count = 2 hw.sensor.hinge.ranges = 0-360,0-360
hw.sensor.hinge.defaults = 180,180
hw.sensor.hinge.areas = 0-987-1440-0, 0-1974-1440-0
hw.sensor.posture_list=1, 2, 3, 4
hw.sensor.hinge_angles_posture_definitions=0-30 & 0-30, 30-150 & 30-150, 150-210 & 150-210, 210-360 & 210-360
