Android emulator - dummy emulator-5554 and AVD … is already running

Solved! by building multiple instances of the phone emulator I wanted.


I've been trying to run this down for two days now and I am absolutely stumped. Running on Windows 10. Project builds fine. I hit run, select Nexus 5x API 28 virtual device, the emulator boots, and the Nexus 5X runs without the app.

Run 'app' again and now my deployment options are a dummy Emulator-5554[Offline] and the Nexus. Selecting the Nexus gets me the "AVD Nexus_5X_API_28 is already running. If this is not the case..." error. Selecting the unwelcomed Emulator-5554 returns an "error launching app" from Android Studio.

So here's what I've tried:
Deleting the Nexus 5x files-- all of them.
Installing a Pixel 2 instead-- problem is the same.
Cold booting Nexus 5x-- no effect.
ADB kill-server.
ADB start-server.
Tracing 5554 to the qemu-system-etc.exe application and killing it.
Deleting local/android/sdk, and reinstalling Android Studio without saved settings.
Different phones and different APIs.
Switching on Developer Mode on the Nexus 5x.

The next step is formatting the hard drive and scorching the earth around it.

Has anyone seen this before?
