Emulator 27.2.4 is now available in the Canary channel. It contains the following changes:
  • Fixed an issue that caused the rotate buttons to not work unless the Extended controls window was open. https://issuetracker.google.com/issues/77258337
  • Some changes have been made to improve the speed of saving an AVD snapshot. If you still experience unusually long saves, please file an issue in Issuetracker, providing details of your CPU, RAM, and settings of any antivirus / firewall / security software that is running.

Avast Issues

We have found that if Avast is installed and Hardware virtualization is enabled or "Enable nested virtualization" is disabled, the emulator will not be able to launch due to conflicts with HAXM. We recommend disabling hardware virtualization features of Avast if Avast is installed. In addition, after Avast hardware virtualization is disabled, please ensure that HAXM is set up properly again with a full re-install of the latest HAXM from the SDK Manager.
