For writing the usb image files, likes the one mentioned at ftp://ftp.freebsd.org/pub/FreeBSD/releases/amd64/amd64/ISO-IMAGES/10.3/,  to usb drives on a mac, see this link https://people.freebsd.org/~seanc/freebsd/create-memstick-osx/ .

The usb images are differentiated from the normal ISO files by the presence of “memstick” in the file name.

Trying to run a android build from Cordova cli requires that all the environment variables are properly set, otherwise it would exit with error. See this page for all the variables that need to be set: http://cordova.apache.org/docs/en/latest/guide/platforms/android/index.html#setting-environment-variables .
