Copied From Android's Developer Site:
Creating an AVD
To create an AVD configuration, execute:
$ android create avd --name my_avd_name --target 1
--name is the name you'd like to give the AVD and target is the ID of a target listed by android list targets.
The AVD name is purely an identifier used to refer to the AVD later. Since it is used as directory name, please avoid using shell or path specific characters.
To learn the various options available when creating an AVD, simply type:
$ android create avd
The android tool will automatically print an explanation of required arguments.
