In last tutorial, I shared the installation steps for Android ADT toolkit in windows machine. Then we learnt about creating the AVD (virtual devices or emulators) and we deployed our hello world app onto emulator. One thing you must have noticed that emulators are dead slow by default. I mean they are so much slow that you can take your lunch in the mean time and they will be loading all the time. Can we improve this slow emulators? Ye, we can. Let’s see how.

• Android Studio does consume memory and when coupled with an emulator it might slow down. As an alternative to the Android emulator I would suggest you could use the Geny Motion emulator. Its really simple to set up and has lesser lags as compared to the default emulator by android.

Speed up a slow android emulator

Step 1) Download HAXM Driver using SDK Manager

To improve the performance of an emulator first thing you will need is installing the “Intel Hardware Accelerated Execution Manager Driver” from SDK Manager you get with Android ADT. Look at the screen shot below.

Step 2) Execute IntelHaxm.exe to install the HAXM driver

This will create the IntelHaxm.exe inside “extra” folder in your android ADT package. Execute this file to install the HAXM Driver which is responsible for virtualization in your system.

Step 3) Update BIOS if driver installation failed

There are chances that above installation process failed and you are advised to update the BIOS configuration related to “Intel Virtualization Technology“. Go ahead and do it. For related information to this step, read the manual received with motherboard when you purchased it.

Generally, when you go to BIOS options by pressing “DEL” key during boot process, you can easily find the menu option “Intel Virtualization Technology” in third tab. Enable this option and restart the machine.

Step 4) Use Host GPU Option

Once Virtualization Technology is enabled, you can use this feature while creating the Emulator by checking the checkbox “Use Host GPU“. This will enable the system’s native support for virtualization for emulator.

Step 5) Test the configuration changes

Now start the emulator and see the major performance gain you obtained using above steps.

This article explains how to use your computer's hardware accelerationfeatures to maximize Android Emulator performance.

Visual Studio makes it easier for developers to test and debug theirXamarin.Android applications by using the Android emulator insituations where an Android device is unavailable or impractical.However, the Android emulator runs too slowly if hardware accelerationis not available on the computer that runs it. You can drasticallyimprove the performance of the Android emulator by using special x86virtual device images in conjunction with the virtualization featuresof your computer.

Accelerating Android emulators on Windows

The following virtualization technologies are available foraccelerating the Android emulator:

1. Microsoft's Hyper-V and the Windows Hypervisor Platform (WHPX).Hyper-Vis a virtualization feature of Windows that makes it possible to runvirtualized computer systems on a physical host computer.

2. Intel's Hardware Accelerated Execution Manager (HAXM).HAXM is a virtualization engine for computers running Intel CPUs.

For the best experience on Windows, it is recommended that you use WHPX toaccelerate the Android emulator. If WHPX is not available on yourcomputer, then HAXM can be used. The Android emulator willautomatically make use of hardware acceleration if the followingcriteria are met:

• Hardware acceleration is available and enabled on your developmentcomputer.

• The emulator is running a system image created foran x86-based virtual device.

Important

You can't run a VM-accelerated emulator inside another VM, such asa VM hosted by VirtualBox, VMware, or Docker (unless using WSL2). You must run the Androidemulator directly on your system hardware.

For information about launching and debugging with the Androidemulator, seeDebugging on the Android Emulator.

Accelerating with Hyper-V

Before enabling Hyper-V, read the following section to verifythat your computer supports Hyper-V.

Verifying support for Hyper-V

Hyper-V runs on the Windows Hypervisor Platform. To use the Androidemulator with Hyper-V, your computer must meet the following criteriato support the Windows Hypervisor Platform:

• Your computer hardware must meet the following requirements:

  • A 64-bit Intel or AMD Ryzen CPU with Second Level Address Translation (SLAT).
  • CPU support for VM Monitor Mode Extension (VT-c on Intel CPUs).
  • Minimum of 4-GB memory.

• In your computer's BIOS, the following items must be enabled:

  • Virtualization Technology (may have a different label depending on motherboard manufacturer).
  • Hardware Enforced Data Execution Prevention.

• Your computer must be updated to Windows 10 April 2018 update(build 1803) or later. You can verify that your Windows versionis up-to-date by using the following steps:

  1. Enter About in the Windows search box.

  2. Select About your PC in the search results.

  3. Scroll down in the About dialog to the Windows specificationssection.

  4. Verify that the Version is at least 1803:

To verify that your computer hardware and software is compatible withHyper-V, open a command prompt and type the following command:

If all listed Hyper-V requirements have a value of Yes, then yourcomputer can support Hyper-V. For example:

Enabling Hyper-V acceleration

If your computer meets the above criteria, use the following stepsto accelerate the Android emulator with Hyper-V:

1. Enter windows features in the Windows search box and selectTurn Windows features on or off in the search results. In theWindows Features dialog, enable both Hyper-V and WindowsHypervisor Platform:

   After making these changes, reboot your computer.

Important

On Windows 10 October 2018 Update (RS5) and higher, youonly need to enable Hyper-V, as it will useWindows Hypervisor Platform (WHPX) automatically.

2. Install Visual Studio 15.8 or later(this version of Visual Studio provides IDE support forrunning the Android emulator with Hyper-V).

3. Install the Android Emulator package 27.2.7 or later. Toinstall this package, navigate to Tools > Android > Android SDKManager in Visual Studio. Select the Tools tab and ensure thatthe Android emulator version is at least 27.2.7. Also ensure thatthe Android SDK Tools version is 26.1.1 or later:

When you create a virtual device (seeManaging Virtual Devices with the Android Device Manager),be sure to select an x86-based system image. If you use an ARM-based system image,the virtual device will not be accelerated and will run slowly.

Hyper-V should now be enabled and you can run your accelerated Android emulator.

Accelerating with HAXM

If your computerdoes not support Hyper-V, you may use HAXM to accelerate the Android emulator. You mustdisable Device Guardif you want to use HAXM.

Verifying HAXM support

To determine if your hardware supports HAXM, follow the steps inDoes My Processor Support Intel Virtualization Technology?.If your hardware supports HAXM,you can check to see if HAXM is already installed by using thefollowing steps:

1. Open a command prompt window and enter the following command:

2. Examine the output to see if the HAXM process is running. if it is,you should see output listing the intelhaxm state as RUNNING. Forexample:

   If STATE is not set to RUNNING, then HAXM is not installed.

If your computer can support HAXM but HAXM is not installed, use thesteps in the next section to install HAXM.

Installing HAXM

HAXM install packages for Windows are available from theIntel Hardware Accelerated Execution Manager GitHub releasespage. Use the following steps to download and install HAXM:

1. From the Intel website, download the latestHAXM virtualization engineinstaller for Windows. The advantage of downloading the HAXMinstaller directly from the Intel website is that you can be assuredof using the latest version.

2. Run intelhaxm-android.exe to start the HAXM installer. Acceptthe default values in the installer dialogs:

When you create a virtual device (seeManaging Virtual Devices with the Android Device Manager),be sure to select an x86-based system image. If you use an ARM-based system image,the virtual device will not be accelerated and will run slowly.

Troubleshooting
