DESCRIBE THE ISSUE IN DETAIL: The emulator CLI's -dns-server option does not seem to work on API 31 or newer.

STEPS TO REPRODUCE:

Run a local dns server and log queries: dnsmasq -dq
Start an API 31 emulator: emulator -avd emulator31 -dns-server 127.0.0.1
Resolve a domain: adb shell ping www.reddit.com
dnsmasq does not show that domain in the log.

However, on API 30, these same steps will result in the dnsmasq showing the queries to reddit.com:

dnsmasq: query[A] www.reddit.com from 127.0.0.1
dnsmasq: forwarded www.reddit.com to <ip>
dnsmasq: reply www.reddit.com is <CNAME>
dnsmasq: reply reddit.map.fastly.net is <ip>

We need to override some DNS entries in order to test our app in environments that do not have external internet access, but it stopped working in API 31 or newer.

Hi, some users reported that installing "Vulkan SDK" helps with this issue. What is your GPU and its driver versions?

Hi, I have installed the Vulkan SDK on my PC, and my GPU is an NVIDIA GeForce RTX 3060 Laptop GPU with driver version 30.0.15.1274. I also tried deactivating the Vanguard anti-cheat, but the AVD still terminated. I’ve attached the log file after deactivating Vanguard.

Regarding the ADB issue ("ADB location has not been initialized"), I ran the adb version command in Command Prompt and successfully retrieved the version. Could you help me check this again?

Marked as fixed.

Could you please try stating the Emulator from the command line this way

cd C:\Users\crazy\Desktop\CODING\AndroidSDK\emulator
emulator.exe -avd Pixel_9_Pro_XL_API_33 -wipe-data -no-snapshot -verbose -feature -Vulkan

and attach its output? If you notice any popups about missing dlls please include them here.

Hi this is the output txt flle

Thank you, please try adding -gpu swangle (this is a software GPU, it will be slow), I think for whatever reason we can't talk to your GPU.

Please consider trying the latest version we have here:

https://developer.android.com/studio/emulator_archive

The attached TXT file contains the output after adding -gpu swangle. Following that, I manually updated the emulator from Android Emulator (35.2.10) Stable to Android Emulator (35.4.3) Canary. I also deleted the old AVD and created a new one, but it still terminated. I’ve attached the report generated after updating the emulator version.

Could you please check this for me?
