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

Question

I'm unable to debug using VSCode for Flutter. I'm using Windows and I'm trying to use an Android emulator.

I have attempted to reinstall Flutter, Android SDK and VSCode to fix the issue, as well as tried setting environment variables.

This is the error that I get when launching debug mode. Failed to launch emulator: Error: Emulator didn't connect within 60 seconds

Are there any better emulators that I can use for both Android and IOS, because I don't even know where to begin with IOS emulators. I'm new to app development and want to get started making applications for both devices.

and restart.

Solution 5

Adding the following variables to $HOME/.bash_profile solved my problem

export ANDROID_HOME=$HOME/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools

flutter emulators to see available devices

1. Restart 'terminal' windows 2. Restart Android Studio, stop emulator, wipe data, run again 3. Make sure you are getting some output or error in terminal windows, if not start with step 1 and 2.

It doesn't say any devices are connected despite having like 5 emulators.

I'm not sure why this was marked down? For anyone else like me who could not get the emulator to start - it would hang at the popup loading screen about 30% through and the qemu process would also hang - this was the solution. In my case I didn't have HAXM installed at all.

If you is using linux, you should give the user permission from the directory /dev/kvm.

This could have been a comment on the question, not an answer.

I'd same problem and "Cold Boot Now" option works fine. No need to wipe device data.

[Boaz]

This is a valid answer. While not an ideal solution, this is the only thing that currently works for me whenever VS Code fails to connect to the emulator, with the message "Emulator didn't connect within 60 seconds"

[MJ33]

worked well for me when other solutions couldn't

I killed qemu process from task manager :D seems easier

Where do you run the command (2)? My standard windows terminal does not know adb.

Why can't flutter launch hardware accelerated devices?

[Merritt]

@PatrickGeyer In general Flutter can and does, this just happened to be an issue. I haven't had this problem myself in some time now.
