Emulator 29.0.0 is now available in the Canary and Dev channels.

Fixes

• On some remote desktop setups, it was possible to get a black screen when launching the emulator on Linux. We now explicitly configure MESA_RGB_VISUAL to avoid this. Details
• Fixed incorrect usage of SO_REUSEADDR. Details
• Fixed issue where rotate buttons would appear on TV AVDs. https://issuetracker.google.com/127956599
• Fixed issue where if emulator was set always on top, the extended controls window would mysteriously appear every time the emulator was rotated. https://issuetracker.google.com/128455869
• To address issues with some Linux installs containing incompatible versions of some Qt dependent libraries, we now package libfreetype, libsoftokn, and libsqlite3 with the emulator.
• Fixed failure to snapshot load on GLES1 apps and API 15 and 16.

AR Macros

The emulator can now play back from a set of preset motions in order to make it easier to test AR apps on the emulator.

The controls can be found in Extended Controls > Record and Playback > Macro Playback. When a macro is played back, the emulator's virtual sensors will generate values that reflect the motion, and the virtual scene camera will update according to the motion.

RAM Usage Metrics

In continuing to address emulator resource usage, the emulator now sends RAM usage metrics in a 10 second interval for opt-in users, in order for us to get a clearer picture of how the emulator is typically used.

Emulator in CI

We're still working to make life easier for our CI users. On Linux, the headless build now does not use pulseaudio nor X11, enabling running in an even wider variety of environments. The system dependent shared libraries that are not packaged with the emulator are now reduced to:

1. linux-vdso.so.1
2. libutil.so.1
3. libm.so.6
4. libdl.so.2
5. librt.so.1
6. libpthread.so.0
7. libgcc_s.so.1
8. libc.so.6
9. ld-linux-x86-64.so.2

Graphics

• Added support for the GLES extensions GL_EXT_texture_format_BGRA8888 and GL_APPLE_texture_format_BGRA8888 if supported on host.
• Vulkan is now supported experimentally on Windows and Linux given a host GPU that supports Vulkan and upcoming Q images (or the latest AOSP master system image). To enable the Vulkan driver and testing Vulkan apps:
• echo "Vulkan = on" >> ~/.android/advancedFeatures.ini
• echo "GLDirectMem = on" >> ~/.android/advancedFeatures.ini

Emulator 28.0.25 is now available in the Stable channel.

• Users were experiencing "unauthorized" emulators due to an incompatible change in adb from platform-tools 28.0.2.
• ADB from platform-tools 28.0.2 can now be safely used with the emulator.
• If you are experiencing issues with "unauthorized" emulators:
• Exit all emulators
• Delete ~/.android/adbkey and ~/.android/adbkey.pub
• adb kill-server
• adb devices
• Wipe data of AVD
• Relaunch emulator
• Fixed twitching, incorrect frame display on Intel GPUs when running Q system images.
• Fixed black screen when using Q system images with Pixel 2 XL skins.
• The latest BIOS binaries are now used to start up the emulator, which can help reduce "vCPU shutdown request" errors that happen sometimes when launching the emulator on Windows.
• Backported fix for wrong display when resuming Q system images from a snapshot.
• Backported headless build. More info on headless builds

Emulator 28.1.10 is now available in the Canary and Dev channels. Changes:

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

Read more

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.
