Hi I updated the mac os big sur 11.2 to 11.3 today.

Android Emulator not opening, but it opens in docks from avd manager. I tried Big sur update from Stack Overflow. But it didn't work for me I used command as per given

~/Library/Android/sdk/emulator/emulator -gpu host -feature HVF -avd PIXEL_3A_API_30

emulator: Android emulator version 30.5.5.0 (build_id 7285888) (CL:N/A)

Anyone know how to solve this problem.

Solution

Based on this post this appears to be an issue with some hypervisor entitlements that got updated in OSX 11.3.

Till an official fix is provided in the emulator app, it can be fixed by creating an entitlements.xml file with the following 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>

and then running

codesign -s - --entitlements entitlements.xml --force ~/Library/Android/sdk/emulator/qemu/darwin-x86_64/qemu-system-x86_64

(the path to qemu might need to be adjusted depending on Android SDK's installation path)

This solution was also suggested on other similar posts, I repeated it here for convenience.
