How to remove an offline emulator from avd devices?

adb remove emulator-5554
device is offline emulator
emulator offline in adb devices
skipping device emulator device is offline
installation failed due to device offline emulator
android offline emulator
adb error more than one device/emulator
skipping device 'emulator-5554' (emulator-5554): device is offline react-native

I've created a couple of AVD-s in Android Studio. They were launching on emulator port 5554. Then I've created another AVD via android avd application, and they are starting on port 5556.

Now with a single emulator running, I get the following output from adb devices -l:

List of devices attached
emulator-5556          device
emulator-5554          offline

I'm using the tooling which cannot supply the -s (specific device) option to adb, so when trying to install an app, I get an error:

error: more than one device/emulator

And I'd like that there be a single connected emulator: the only one that I'm running.

I thought that removing the old Android Studio-created devices would do the trick of removing the emulator-5554, but nope. Even new devices created in Studio will open on 5556. So I've ended up with a forever-offline zombie emulator-5554 that screws up my build tooling.

How can I force the new emulators to be run on port 5554 and/or remove the offline emulator-5554?

(Running Ubuntu 16.04 if it matters.)

When I am facing the same issues than doing like below:

  1. Restart adb by issuing adb kill-server followed by adb start-server in a command prompt
  2. Disable and re-enable USB debugging on the phone
  3. Rebooting the phone if it still doesn't work.

99% of my issues have been resolved with these steps.

  • Thanks, the kill-server and start-server combo worked!
  • I don't know whether this is a solution, but after trying all the three methods suggested by @Chandrama Prasad 1) Restart adb by issuing 'adb kill-server' followed by 'adb start-server' at a cmd prompt 2) Disable and re-enable USB debugging on the phone 3) Rebooting the phone if it still doesn't work. when all the three did not work, I simply changed my USB cable, and nos duplicate device shown after that. Please note that I was not using emulator but personal Android device. Simply put there was a trouble in my data cable.
  • I forgot to mention that I'm running Ubuntu. Thanks for the suggestion though.
  • Normally killing the ADB process do the trick also. You could also try to uncheck "Launch From Snapshot"
  • Thank you for this. I didn't even think BlueStacks was causing the issue.
