I updated today the macOS to Big Sur 11.3, the android emulator can not work any more:

My Computer: Macbook Pro 2019

Android Studio Version: 4.1.3

Android Simulator Version: 30.5.5

Message: The emulator process for AVD xxx was killed.

I tried reinstall the android studio and restart, but the error is still the same. I can not start the android Emulator... :(

Error is here, It somehow related to GLDirectMem/Vulkan:

Do you have idea, how to fix it?

This error occurs because Apple has made changes to the hypervisor entitlements. What you want to do is:

  1. Use /Users/<username>/Library/Android/sdk/emulator/qemu/darwin-x86_64/qemu-system-x86_64 as the directory for qemu

  2. Add the entitlement to the qemu-system-x86_64 binary by:

    • First create an xml file named entitlements.xml (does not matter where) with this content:
    <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" 
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>com.apple.security.hypervisor</key>
    <true/>
</dict>
</plist>
    • Then sign the qemu binary with it:
    codesign -s - --entitlements entitlements.xml --force /Users/<username>/Library/Android/sdk/emulator/qemu/darwin-x86_64/qemu-system-x86_64

    I am very confused, this problem I just got after the update to the latest version. Before the update everything was fine util yesterday. However, the solution link you showed me is already nearly 5 months ago... Somehow, my time is slower than the author 5 months... – xirururu Apr 28 '21 at 22:04

Check 1:

If you have a Docker installed, stop that. It interrupt the emulator.

Check 2:

Try to launch your emulator from the command line, type:

  1. cd $ANDROID_SDK_ROOT
  2. tools/emulator -list-avds
  3. tools/emulator @name_of_avd -verbose

The ANDROID_SDK_ROOT environment value should point to the android SDK location. You can find this in android studio under the menu tools -> sdk manager.

Check 3:

  1. Delete all AVD's that you currently have.
  2. Go to Preferences >> Android SDK >> SDK Tools
  3. Uninstall Android Emulator
  4. Restart Android Studio
  5. Re-install Android Emulator from the same place.
  6. And finally create a new emulator

Sidenote:

I made a documentation for AMD processors facing emulator issue on Windows systems. Probably something from there could help also. Give it a shot and let me know if it worked. Cheers!

PS: Make sure you installed the latest Vulkan driver for MacOS (Intel CPU) Download the driver from my other Intel documentation or try this usefull post I found.

  • Hi thanks for the answer, but what is vulkan? How can I install it? – xirururu Apr 28 '21 at 21:03
  • I tried to start from console, it reported missing the emulator engine for x86 cpu: ```emulator:Looking for emulator-x86 to emulate 'x86' CPU emulator:Probing program: /Users/yinggu/Library/Android/sdk/tools/emulator64-x86 emulator:Probing program: /Users/yinggu/Library/Android/sdk/tools/emulator-x86 PANIC: Missing emulator engine program for 'x86' CPU.``` – xirururu Apr 28 '21 at 21:07
  • Alright now I know what the problem is. Your Macbook uses an Intel CPU and the acceleration is missing for the Emulator. Please download the vulkan driver from my Link under "PS:" in my answer. Did you tried the written "Checks" before? – Ole Pannier Apr 28 '21 at 21:12
  • I added another Link for macOS I found. Now you should definetely get the problem fixed. :) – Ole Pannier Apr 28 '21 at 21:15
  • I did the all the check 1, 2, 3. Just finished the check 3. After reinstall emulator, it is the same error, so i think, I should install the vulkan as you suggested. Will do it now. :D – xirururu Apr 28 '21 at 21:15
  • I just tried to install the MoltenVK, but too many steps to follow... need to figure out. For short I followed @Mayokun suggestion, solved this problem. Anyway, thanks so much for the help! I think, the installation of the Vulkan should be also a solution. *^_^* – xirururu Apr 28 '21 at 21:55
  • You are welcome. Glad that Mayokun and I could help you! :) – Ole Pannier Apr 29 '21 at 14:02

30.5.6 is out and it works fine. Apparently there has been any incompatibility between 30.5.5 and previous with Big Sur 11.3.
