Minor revision 26.0.3 (May 2017)

  • Adds online-updateable feature flags for quickly addressing issues stemming from problematic hardware configurations. This allows Google to roll out fixes and features that are dependent on user configurations by updating server-side flags. If you notice issues with specific hardware, please report a bug so we can investigate the problem.
  • New support for rotary input for Android Wear API level 25 system images. To emulate the rotary input dial on a Wear device, click the Rotary Input tab on the extended window.
  • The Crash Reporting dialog is now resizable and no longer resets When to send crash reports to Ask without input.
  • The 32-bit emulator now requires that the maximum AVD RAM size be less than or equal to 512 MB, in order prevent the emulator from running out of room in the 2 GB virtual address space.
  • Adds support for absolute paths in emulator images.
  • Adds a new tab in the extended window for Google Play Store images that displays the Play Services version and a button to check for updates to Play Services.
  • Adds a dropdown to select the OpenGL renderer on the Emulator Settings page. If you are experiencing issues with the OpenGL driver on a Windows machine, try using the ANGLE (D3D11) or ANGLE (D3D9) options (requires a restart). If you are experiencing issues with the OpenGL driver on a non-Windows machine, try using the Swiftshader software renderer (requires a restart).
  • Fixes a rare crash on exit when the emulator receives both exit and minimize commands.
  • Fixes a scaling issue when changing displays on a Mac machine. (Issue 268296)
  • Fixes an issue where the emulator takes 300% of the CPU and holds it after resuming the host computer from sleep or when the emulator has been running for a long time.
  • Fixes a crash when the emulator is shutting down.

Updates with HAXM v6.1.1 (March 2017)

Note: HAXM v6.1.1 is available for Mac users through the SDK Manager as of March 30th, and will be available for Windows users soon.

Revision 26.0.0 of the Android Emulator supports HAXM v6.1.1, which includes the following updates:

  • Enables Performance Monitoring Units (PMU) emulation. (Issue 223377)
  • Fixes coexistence with VirtualBox and Docker on Macs. (Issue 197915)
  • Revises the installation error message displayed when the installer fails to detect Intel VT-x on Windows, usually because Hyper-V is enabled.
  • Adds support for accelerating the Android Emulator in a Hyper-V-based Windows VM. This update requires that the host Hyper-V instance (the one that manages the Windows VM/guest) use the latest version of Hyper-V with nested virtualization enabled. Hyper-V must be disabled in the guest Hyper-V instance (the Windows VM).


New features and bug fixes

Revision 25.3.0 (March 2017)

As of this release, the Android Emulator will be released separately from the SDK Tools. This release contains a variety of performance improvements, new features, and bug fixes.

Minor revision 25.3.1 (March 2017)

  • Fixed a crash occurring on some GPU configurations by disabling GLAsyncSwap by default. This feature was added in 25.3.0 to improve frame timing and frames per second for games and video, but causes the emulator to fail on some unknown machine configurations. You can manually enable it by opening the android_sdk/emulator/lib/advancedFeatures.ini file and setting GLAsyncSwap = on.
