sentence: a demo at google i/o 2012 showed samsung galaxy nexus and nexus&nbsp;7 users connecting to the nexus q over wifi and selecting music and video to be played by the q. this functionality is similar to apple 's airplay technology , however , unlike airplay , where content is streamed directly from the controlling device , an android device merely tells the q what content to play , and then the content is streamed directly from google play to the q over the internet .
