Emulator 28.1.8 is now available in the Canary and Dev channels. Changes:

Project Marble:

• There are no direct improvements to CPU/RAM usage in this build, though there are the following compatibility and quality changes:
• Headless emulator build. When using the emulator for CI, it can be hard to set up due to 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 plus QEMU executables that do not depend on Qt. On Linux, there is a remaining 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. We also provide a review other command line options that can be useful for running in such an environment:
• $ANDROID_SDK_ROOT/emulator/[emulator|emulator-headless] -avd avdName [-gpu [swiftshader_indirect|host]] [-no-snapshot[-save|-load]] [-read-only] [-no-accel] [-no-window]
• emulator versus emulator-headless:
• emulator: Run standard emulator with UI if possible. Qt libraries and their dependencies are linked.
• emulator-headless: Run emulator without UI. Qt and its dependencies are not included. For now, only kernels on x86_64 and aarch64 are supported. Though, this should cover all x86 system images, x86_64 or not, back to API 27.
• -gpu option:
• swiftshader_indirect: Use Swiftshader software renderer, which is the most portable across setups.
• host: If the machine has a hardware GPU accessible, use host.
• -no-snapshot:
• Cold boot and exit without saving a snapshot.
• -no-snapshot-save:
• Boot from the last snapshot, if any, but exit without saving a snapshot.
• -no-snapshot-load:
• Cold boot and save a snapshot on exit.
• -read-only:
• Boot from the last snapshot, if any, and allow multiple simultaneous invocations of the emulator launcher on the same AVD. No snapshots are saved on exit and changes to disk are discarded.
• If booting from a snapshot, memory is also shared in a copy-on-write manner between AVD instances, which can save memory.
• -no-accel:
• This can be useful if the environment does not support virtualization which can be common in Jenkins environments.
• -no-window:
• This can be used in conjunction with the normal emulator launcher if Qt libraries are not an issue. Otherwise, run with emulator-headless; the behavior should be identical.
• Quickboot regression fix. Fixed Quickboot not working with -no-window / headless mode.
• Landscape frameless mask fix. Fixed wrong masking when frameless AVDs were booted with 'landscape' initial orientation.
• Qt 5.12. Upgraded Qt libraries to Qt 5.12 LTS.

Emulator 28.1.7 is now available in the Canary and Dev channels. Changes ...

Read more

Emulator 28.1.7 is now available in the Canary and Dev channels. Changes:

Project Marble:

• Added ADB scripts to increase screen-off timeout to INT_MAX milliseconds (~24 days). This is, again, to address high emulator usage at idle. Here is the breakdown:
• To recap, the most significant source of spinning fans when the emulator is seemingly idle, is tasks started by GMScore shortly after cold boot, plus heavy levels of app updates where the user's entire machine is pegged from installing updated apps in the background.
• The emulator typically defaults to being on emulated AC charging. This seems to be the top contributor to this heavy level of background activity, especially on Google APIs / Play images with GMScore. Apps download and update all the time, sometimes bringing the guest down to 0% idle for extended periods.
• If we go to the Extended Controls > Battery page and set the emulator to be without the AC charger ("None" setting) and set the emulator to "Not charging", this greatly decreases background activity.
• However, if the emulator is on battery power, the screen can turn off by itself, which is undesirable.
• Because of this, we've changed the emulator to send an ADB command to increase the screen off timeout to INT_MAX milliseconds (~24 days). This allows users to put the emulator on battery power for a better experience due to lower background activity.
• The exact command is:
• adb shell settings put system screen_off_timeout 2147483647
• However, we cannot also put the emulator on battery mode by default right away, due to the possibility of the adb command being dropped and causing unintended screen off events for users.
• We plan to address this fully by releasing system images with the screen-off timeout setting baked in, so the emulator can safely default to battery mode.
• Snapshots: On snapshot load, the guest clock is now immediately updated to the current time.
• UI: Divider lines in the keyboard shortcuts table have been restored.

Vulkan

• Compressed ETC2/EAC texture support: Our compressed texture emulation now passes all dEQP tests for ETC2/EAC images, allowing Vulkan apps that use compressed ETC2/EAC textures to run on without requiring native support for ETC2/EAC on the host GPU. See 28.1.6 release notes for the current way to get started with Vulkan.

Emulator 28.1.6 is now available in the Canary and Dev channels. Changes:

Project Marble:

• Decreased idle CPU usage on macOS. On macOS, we've switched from select() to kqueue() for the QEMU main loop. kqueue() is a more efficient way to wait on events on BSD-like systems, burning less CPU than select(). This should decrease CPU usage of the main loop, especially when the emulator is idle.
• Fixed hard-to-reproduce freeze on launch. It seems that Qt libraries sometimes lose signals, which resulted in a "Detected a hanging thread" on launch. We have worked around this bug.

Build

Emulator binary size should now be back to normal. We are also building more of our dependencies from source in order to lower risk of ABI incompatibilities and make the build more reproducible.

Vulkan: Experimental Support for ROM Developers

Changes in AOSP master:

• Updated emulator prebuilts in AOSP.
• The prebuilt emulator in AOSP master has been updated to 28.1.6.
• The prebuilt emulator kernel in AOSP master has been updated to a variant of a 4.4 kernel that includes the necessary driver for Vulkan HOST_COHERENT memory.

ROM developers can now run a Vulkan-enabled emulator in the AOSP build environment on the AOSP master branch. This is an experimental level of support, mainly oriented to developers who work on system images, drivers, and game engines. Many extensions are still missing. 

However, https://github.com/googlesamples/android-vulkan-tutorials should be able to run, and HOST_COHERENT memory is supported. Instructions (for a Linux host):

mkdir aosp-master
cd aosp-master
repo init -u https://android.googlesource.com/platform/manifest -b master --depth=1
repo sync -c -j12
. build/envsetup.sh
lunch sdk_phone_x86_64-userdebug
make -j12
emulator -no-snapshot -feature Vulkan,GLDirectMem

Emulator 28.1.5 is now available in the Canary and Dev channels. Changes:

• Project Marble:
• Changed how the default window size of the emulator is calculated so as to fill more of the screen.
• Some users were concerned that the previously smaller size was not changeable; it has always been the case that the emulator window can be resized by dragging near the corners, even if there is no window frame.
• Decreased overhead of the OpenGL emulation driver on the host side to use less CPU per draw call.
• Vulkan Support Check. The emulator now checks the host side Vulkan driver, querying the level of support for Vulkan features. This check is a preliminary step for further Vulkan support in the future, and should not interfere with normal operation.
• If this check on startup ends up crashing or hanging the emulator, please tell us your OS and hardware GPU setup along with whether you are running the emulator with or without a display attached.
• In a future version, we will be tracking metrics from this check.
• Note: This download is bigger than before due to lack of symbol stripping. This is a temporary issue with our build infrastructure and will be resolved soon.
