Error: Emulator didn't connect within 60 seconds

[MaisGurbanov]

When I am trying to launch an Android emulator through the VS Code, I am receiving the following error:

"Failed to launch flutter emulator: Error: Emulator didn't connect within 60 seconds".

Below is the output for "flutter doctor -v" command outside of the VS Code:

I can launch an emulator through the terminal by executing the "emulator -avd flutter_emulator" command and it launches successfully. Then VS Code also detects that emulator and displays it in the devices bar at the bottom part.

[rasreee]

same here, but for iOS - don't really care for Android.

My error in VSCode Debug Console looks like:
Exception attempting to connect to the VM Service: SocketException: OS Error: Connection refused, errno = 61, address = 127.0.0.1, port = 58050

My emulator works - doesn't matter what device I use (saying this b/c someone mentioned using iPhone SE is relevant b/c it's not new enough?).

I've made sure to:

• add Google-Service.plist by right-clicking Runner and Add Files... in the ios/Runner XCode workspace
• uncommenting platform number 13.0 in Podfile
• running pod repo update
• losing my mind w/ a bunch of other attempts i'll try to remember everything i've tried...

@MaisGurbanov when you launch the emulator from VS Code and get this message, do you see the emulator launch and appear? If so, does it show up in flutter devices once it is loaded? (The output of flutter doctor you posted says no connected devices, but it's not clear if you ran it after launching the emulator). Could you try capturing a log using the Dart: Capture Logs command (you can untick Analysis Server, but leave everything else ticked).

@rasreee this seems like a different problem with a different message, could you file a separate issue and also include a log captured with the above command? Thanks!

You can try to wipe the data of the particular device.

Go to -> Android Studio -> Tools -> AVD Manager -> [Select the down triangle on your chosen device] -> Wipe data.

Now retry.

This one works well for me

It worked for me too, thank you.

This does works but it keeps happening often. Any permanent fix on this?

I'm working on a MacBook Air with M1 processor. If I run the iPhone Simulator, I can successfully use it in VSCode for debugging a Flutter app.

But I cannot get VSCode to connect to the Android Emulator. The Emulator launches when I choose to Start Pixel 3 API S. But I then get the error "Error: Emulator didn't connect within 60 seconds".

Any thoughts on how to get VSCode to connect to the Android Emulator from a Mac with M1 processor?

[DanTup]

@lukertaylor does the Android emulator show up when you run flutter devices from a terminal after starting it?

[lukertaylor]

Thanks for responding so quickly Danny.

`1 connected device:

Chrome (web) • chrome • web-javascript • Google Chrome 91.0.4472.114

• Device emulator-5554 is offline.`

[lukertaylor]

And if I start the iOS Simulator, I get:

`luke@Lukes-MacBook-Air ~ % flutter devices
2 connected devices:

iPhone 12 Pro Max (mobile) • 92D4EACC-982F-45CE-8AA2-33312D303A32 • ios
• com.apple.CoreSimulator.SimRuntime.iOS-14-5 (simulator)
Chrome (web) • chrome •
web-javascript • Google Chrome 91.0.4472.114

• Device emulator-5554 is offline.`

[DanTup]

@lukertaylor

• Device emulator-5554 is offline

That looks like the problem. VS Code gets the device information from Flutter, so if Flutter believes the device is offline it won't provide it to us.

There are a few reports of this in the Flutter issue tracker you might want to read through to see if any of their solutions work (for example this one). Hope that helps!

[lukertaylor]

Thanks Danny. I've got it sorted now. There were two things I needed to do:

1. kill the process running on 5554 (https://stackoverflow.com/questions/3152681/android-emulator-5554-offline/26423404#26423404)
2. downgrade the emulator from release 3 to release 2 (https://stackoverflow.com/questions/67230200/emulator-appearing-offline-on-m1-mac-after-the-last-update-of-arm64-v8a)

[DanTup]

Great, glad you sorted it!

[DanTup]

@harguilar have you tried any of the suggestions above, or confirmed that the device shows up in flutter devices?

[harguilar]

Hi @DanTup,
Thanks for the quick reply, I tried the above suggestions, when I run flutter devices I only see the below devices:
macOS (desktop) • macos • darwin-x64 • Mac OS X 10.15.7 19H524 darwin-x64
Chrome (web) • chrome • web-javascript • Google Chrome 91.0.4472.114
However, if I run flutter emulators
4 available emulators:

apple_ios_simulator • iOS Simulator • Apple • ios
Android_ARMv7a_Nougat • Android ARMv7a Nougat • • android
Android_Accelerated_Nougat • Android Accelerated Nougat • • android
Nexus_6_API_R • Nexus 6 API R • Google • android

I see all the above ones. But When I tried to run then I get the error as the title of this tread.

[DanTup]

flutter emulators shows emulators that have not been started, so it's expected they'd show up there.

If the device isn't showing in flutter devices, that will be why VS code isn't detecting it - VS code is using Flutter's device list to tell when a device finishes starting up.

I would probably try deleting the emulator and recreating it through Android Studio, and see if that makes any difference (launch it from Android Studio and then see if that shows up in flutter devices).

Thank you so much man! I've been stuck at this for 3 days.
The downgrade did the job for me!
Finally I have a working Android emulator with Flutter on my M1 macbook pro.

[lukertaylor]

Hey @alimirmohammad, really glad you got it sorted. Thanks go to @DanTup who helped me out.

Good luck with your Flutter development!

Have the same Issue, follow the steps you provided and everything works fine!! thanks for sharing the solution

[labcerouno]

@lukertaylor's workaround did the trick, but... does anybody at flutter team know that?

[AlemsegedT]

It launches the emulator but displays the Failed to launch Pixel 2 XL API 25: Error: Emulator didn't connect within 60 seconds

[DanTup]

@AlemsegedT after it's started, does it show up if you run flutter devices from the terminal?

[AlemsegedT]

Hey Danny @DanTup thanks for the response it didn't show up but I wipe the data of emulator and cold booted it and I also updated the flutter version it now works thank you again

[MGBarri]

@VicCislari fix worked for me!
