Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. This article explains how to use your computer's hardware acceleration features to maximize Android Emulator performance.

Visual Studio makes it easier for developers to test and debug their Xamarin. Android applications by using the Android emulator in situations where an Android device is unavailable or impractical. However, the Android emulator runs too slowly if hardware acceleration is not available on the computer that runs it. You can drastically improve the performance of the Android emulator by using special x86 virtual device images in conjunction with the virtualization features of your computer.

Hyper-V is a virtualization feature of Windows that makes it possible to run virtualized computer systems on a physical host computer. The Android emulator will automatically make use of hardware acceleration if the following criteria are met:.

You must run the Android emulator directly on your system hardware. For information about launching and debugging with the Android emulator, see Debugging on the Android Emulator. Before enabling Hyper-V, read the following section to verify that your computer supports Hyper-V. Hyper-V runs on the Windows Hypervisor Platform.

To use the Android emulator with Hyper-V, your computer must meet the following criteria to support the Windows Hypervisor Platform:. Your computer must be updated to Windows 10 April update build or later. You can verify that your Windows version is up-to-date by using the following steps:. Scroll down in the About dialog to the Windows specifications section.

To verify that your computer hardware and software is compatible with Hyper-V, open a command prompt and type the following command:. For example:. If your computer meets the above criteria, use the following steps to accelerate the Android emulator with Hyper-V:. Enter windows features in the Windows search box and select Turn Windows features on or off in the search results. Install Visual Studio Install the Android Emulator package Select the Tools tab and ensure that the Android emulator version is at least When you create a virtual device see Managing Virtual Devices with the Android Device Manager , be sure to select an x86 -based system image.

The value of mode can be set to one of the following options:. The following mode options are deprecated:. Skia helps the emulator render graphics more smoothly and efficiently. VM acceleration uses your computer's processor to significantly improve the execution speed of the emulator. A tool called a hypervisor manages this interaction using virtualization extensions that your computer's processor provides. This section outlines the requirements for using VM acceleration and describes how to set up VM acceleration on each operating system.

To use VM acceleration with the emulator, your computer must meet the general requirements in this section. Your computer also needs to meet other requirements that are specific to your operating system.

In addition to the development environment requirements, your computer's processor must support one of the following virtualization extensions technologies:. Most modern processors support these virtualization extensions. If you're not sure whether your processor supports these extensions, check the specifications for your processor on the manufacturer's site.

If your processor doesn't support one of these extensions, then you can't use VM acceleration. Without a hypervisor and VM acceleration, the emulator must translate the machine code from the VM block by block to conform to the architecture of the host computer. This process can be quite slow. With a hypervisor, the VM and the architecture of the host computer match, so the emulator can run code directly on the host processor using the hypervisor.

This improvement drastically increases both the speed and performance of the emulator. The hypervisor that will work best for you depends on your computer's operating system and configuration.

For more information, see one of the following sections:. You can use the emulator -accel-check command-line option to check if a hypervisor is currently installed on your computer. The following examples show how to use the emulator accel-check option.

Quite a few features in Windows 10 will enable Hyper-V implicitly. Users may not even know Hyper-V is activated when they enable one of these features. This list is not exhaustive, please notify us on our bug tracker if you find an item that should be included here. Double-check that the features listed above are also disabled when disabling Hyper-V.

Reference Microsoft documentation and the examples below to find out how each individual feature can be disabled. Some platforms fail to immediately disable Hyper-V when it is switched off. Please file a bug on Microsoft's issue tracker when this occurs. After installing Intel HAXM, confirm that the virtualization driver is operating correctly by entering the following command in a Command Prompt window:. You can adjust the amount of memory available to the Intel HAXM kernel extension by running the installer again.

To install from the SDK Manager , follow these steps:. After installation, confirm that the driver is operating correctly by entering the following command in a Command Prompt window:. Successfully completing a new installation would have the following output:. Upgrading an installation would result in the following output, which includes messages regarding the old driver's uninstallation:.

On Mac OS X v Framework fails to initialize. After installation finishes, confirm that the new kernel extension is operating correctly by opening a terminal window and running the following command:.

You should see a status message containing the following extension name, indicating that the kernel extension is loaded:. Before you uninstall it, shut down any x86 emulators that are currently running, then run the following command in a terminal window:.

Running KVM requires specific user permissions. Make sure that you have sufficient permissions as specified in the KVM installation instructions. You can use the emulator -accel-check command-line option to check whether you have KVM installed. Alternatively, you can install the cpu-checker package containing the kvm-ok command. An output of 1 or greater means that virtualization is supported. An output of 0 means that your CPU doesn't support hardware virtualization.

If you get the following error, it means that you can still run virtual machines. Your virtual machine will be slower without the KVM extensions. Cosmic Lucid Karmic 9.
