Emulator 27.1.10 is now available in the Canary channel.

This version of the emulator includes various tweaks and stability improvements applied on top of Emulator 27.1.7 in the Stable channel.

Changes:

• When using an attached webcam, 720p is now available as a capture resolution. Going forward, this will be required in API 27 images and any attached webcam used will need 720p support.
• Fixed an issue where webcam capture from attached webcam would sometimes output a distorted / all-green image.
• Fixed an issue where it was possible to spuriously trip "emulator: ERROR: detected a hanging thread 'Qt event loop'. No response for 15000 ms" without an actual hang.

If you are still experiencing hangs or other instabilities, please file an issue here: https://issuetracker.google.com/issues?q=componentid:192727

A new version of the Android 8.1 system image is now available for the Android Emulator. You can get it from the SDK Manager as "Google Play Intel x86 Atom System Image", API 27, revision 3.

We're excited to bring you this update to the Android 8.1 system image because it is now a CTS compliant image that includes the Play Store!

We've also fixed the following major issues:

https://issuetracker.google.com/issues/70919913 - API 27 images have no ro.opengles.version set

https://issuetracker.google.com/issues/73230983 - E/Google Maps Android API: Google Maps Android API v2 only supports devices with OpenGL ES 2.0 and above

https://issuetracker.google.com/issues/70823706 - 27 API emulator is very laggy.

This API 27 image also contains a working implementation of Camera HAL3 (https://source.android.com/devices/camera/camera3), allowing developers to use the latest camera APIs.
