hey,

are you trying to run two emulators?
did you edit you dev.nix file?
from that log, it looks like it was about start another preview.
typically i think the android emulator just runs on localhost:5555
:slight_smile:

Sorry for the late response. It looks like there’s somewhere in your code (or dev.nix) that references emulator-5554, can you find it and change it to “localhost:5555” please ? (as the comment above corrrectly points out)

I’ve noticed localhost:5556 showing up if you try to flutter run a second project in a terminal while the default myapp is running,

Is there a doc for idx describing how to change from default flutter myapp to a new project created with flutter create?
