By the way, shall we keep the option --avd or use --emulator instead? Just like connect --emulator.

By the way, shall we keep the option --avd or use --emulator instead? Just like connect --emulator.

To me, even putting --avd under the install subcommand does not make much sense because we are not installing anything but "creating" a virtual device out of the things we've already installed. But I guess creating a new "create" subcommand just for this does not make much sense, so the "install" subcommand is fine for now.

Coming to your question, install --emulator might strike as if it will install the emulator software/binary which is not true here. The command is for creating an Android Virtual Device, so --avd is correct here.

Superb work on this, works brilliantly! Just need to do better error handling.
