CodePudding user response:
of course you can launch an Android virtual device outside of any IDE, you just want to run:
\path\to\android\sdk\emulator> emulator -avd <avd_name>
To get a list of AVD names, enter the command:
\path\to\android\sdk\emulator> emulator -list-avds
Once the virtual device starts, the ADB should be able to connect to it.
