Some more context regarding this issue: https://stackoverflow.com/questions/73417527/android-emulator-initial-network-call-delayed-by-several-seconds/

It's happening on 31.3.10. Reverting to 31.2.10 fixes the problem.

It seems like we can repro the issue with embedded emulator. I used a stopwatch to record how long it takes for Google Sign-In page to load for the first time.

1, stand-alone emulator version (31.3.10): 4 seconds

2, embedded emulator (31.3.10): 15 seconds.

I am using Windows 10 with Intel Core i7-11850H@ 2.50GHz with 32GB RAM.

Ranjit is also able to repro the issue on Windows with Intel CPU. The problem is essentially in the first network connection. I asked Ranjit to help me with bisection mentioned in #3.

Time taken to show the Gmail Sign In page when AVD launched in embedded mode (Used Pixel_4a_API_31)

Emulator Version : 31.3.9-8716652 about 17 seconds
Emulator Version : 31.3.10-8779787 about 18 seconds
Emulator Version : 31.3.10-8803787 about 20 seconds

RE#6 Thanks Ranjit for helping out with bisecting. I think the issue probably existed before I checked in the network related CLs. We will keep bisecting.

wd...@google.com <wd...@google.com> #8Aug 31, 2022 07:41PM

Maybe the issue is caused by this CL. Let's try if build (8376731) still has the problem and how does it compare with build (8408262).

wd...@google.com <wd...@google.com> #9Aug 31, 2022 10:36PM

According to ranjitkumar@, "It took about 28 seconds with Emulator version 31.3.6-8376731 and It took about 35 seconds for me with Emulator version 31.2.10-8420304" So we are probably chasing down a problem that might just be lingering for very long time.

And our observation is somewhat contradictory to what the user had reported because they believe it's a regression from 31.2.10.

The issue should be fixed with CL, which will be release in canary next week.

Marked as fixed.

@ranjitkumar

Here is the verification steps for this bug.

Host Operating System: Windows 10

Set up: Disable ipv6 manually in Windows by referring to the link. To confirm that ipv6 is not in use, go to http://test-ipv4.com/ and make sure that ipv6 is not supported.

Repro step: 1, Create AVD with API 31 and wipe data before each run.

2, Run AVD and make sure it is cold boot.

3, Immediately after the device boot completes, go to Gmail or Google and try to load the Google Sign In page.

4, Google Sign In page should take more than 1 minute to load for the buggy version (32.3.10). Google Sign in page should take less than 20 seconds for the new version (with fix in CL to load.

Thanks for the steps Weilun.

When I tried to load the sign in page after disabling the ipV6 manually it takes more than 2 minutes for the sign in page to show up with stable Emulator 31.3.10.

I will verify the fix in the upcoming Emulator build.

ra...@google.com <ra...@google.com> #13Sep 13, 2022 09:51PM

Verified by ra...@google.com.

This bug has been verified as fixed with the latest Emulator build that is shared with QA.

It takes about 20 seconds for the Gmail sign in page to show up on AVD(Pixel_4a_API_31) with Emulator 31.3.11-9032202 using ipv4 in stand alone mode.

OS : Windows 10
