Hyper-V compatible Android emulator now available

An annoying issue for Android developers on Windows is that the official Android emulator uses Intel’s HAXM hypervisor platform, which is incompatible with Microsoft’s Hyper-V.

The pain of dual-boot just to run the Android emulator is coming to an end. Google has announced that the latest release of the Android Emulator will support Hyper-V on both AMD and Intel PCs. This a relief to Docker users, for example, since Docker now uses Hyper-V by default.

Google Product Manager Jamal Eason has made a rather confusing post, positioning the new feature as mainly for the benefit of developers with AMD processors. Intel HAXM does not work with AMD processors.”Thanks to on-going development by Intel, the fastest emulator performance on Windows is still with Intel HAXM,” says Eason, stating that HAXM remains the default on Intel PCs and is recommended.

However the new Hyper-V support works fine on Intel as well as AMD PCs. The official docs say:

Though we recommend using HAXM on Windows, it is possible to use Windows Hypervisor Platform (WHPX) with the emulator. Situations in which you should use WHPX with the emulator are the following:

  • You need to use Hyper-V at the same time.
  • You are using an AMD CPU.

The new feature is “thanks to a new Microsoft Windows Hypervisor Platform (WHPX) API and recent open-source contributions from Microsoft,” says Eason.

It is another case of Microsoft doing the hard work to make Windows a better platform for developers, even when they are targeting non-Windows platforms (as is increasingly the case).
