Emulator 28.1.10 Canary
Friday, March 8, 2019
Emulator 28.1.10 is now available in the Canary and Dev channels. Changes:
Project Marble
Performance monitoring
. We've added more detailed monitoring to emulator performance and resource usage.
SHOW_PERF_STATS=1
. This environment variable enables tracking CPU and memory usage and also breaks down memory usage of graphics versus total resident memory.
ANDROID_EMU_TRACING=1
. This environment variable enables printing every time an input or graphics operations takes a long time (defined to be >1 ms).
This is to address concerns from users where on Windows, more jank (dropped frames) is experienced versus on macOS/Linux. We're now paying more attention to this issue, and noticed that long graphics operations happen tend to take even longer on Windows, which may point to the cause.
Graphics optimization
. Sped up uniform uploads (
glUniform*
) by 10-20%.
LC_ALL=C
by default
. To address issues with crashes and other problems stemming from different locales, we now set
LC_ALL=C
by default.
Host audio input control for CI setups
. To work better with CI setups that need to use host audio input, we've added a command line flag and console command to allow host audio.
Command line flag:
-allow-host-audio
: Microphone will be activated on startup.
Console command:
adb emu avd hostmicon
,
adb emu avd hostmicoff
: Control whether host audio input is used.
More quality improvements for CI users
.
emulator-headless
now should not depend on system libc++, and properly uses the included libc++ that we ship.
To address issues with
unexpected EOF
when logcat prints a lot, we've increased the logcat buffer size to 2M.
Vulkan
Removed a code path where Vulkan support check was incorrectly ran when the feature flag was not enabled.
We now support
VK_ANDROID_external_memory_android_hardware_buffer
, enabling Skia Vulkan Android UI with a properly set-up system image.
Foldable device
We saw that foldable emulator UI was being activated improperly in some cases. To address this, foldable is now a hardware property in AVD config.ini.

Emulator 28.1.9 Canary
Friday, March 1, 2019
Emulator 28.1.9 is now available in the Canary and Dev channels. Changes:
Project Marble:
To address CPU usage, we now run the following ADB commands on a cold boot when detecting boot complete:
adb shell settings put system screen_off_timeout 214783647
adb shell pm revoke com.google.android.googlequicksearchbox android.permission.RECORD_AUDIO
The first command increases the screen off timeout so the emulator can be used in battery mode without charging.
In battery mode, background CPU usage is greatly reduced.
In AC charging mode, GMSCore background operations such as app updates can take over all CPU cores of the entire device with no warning (and by extension, the user's machine).
We shipped the screen off timeout command in
28.1.7
, but we are adding a second invocation on boot complete in order to address issues with sending the command reliably.
The second command revokes microphone permissions for the Google search app, which greatly reduces background CPU usage on the home screen and in the launcher when the Google search app is active.
In
28.1.4
we disabled host audio input by default.
In
28.1.4
we also described how revoking the microphone permissions would also suppress the request on the Android OS end, which greatly reduces background CPU usage. Now, permission revoking is done automatically by default on every cold boot.
Removed a major source of "VCPU shutdown request" errors on Windows when launching the emulator.
We collected crash data from the Vulkan support check and we noticed that users on AMD GPUs will need to update their drivers to a recent version. We tested the following version on RX 580 and it seems to have resolved a crash on calling
vkCreateInstance
:
Driver version: 25.20.15021.1007
Radeon version: 19.2.2
Due to the issue on AMD GPUs, we have turned off the Vulkan support check for now and will instead use a whitelist of GPUs.
