when using fresh image emulator first time there aren't location coordinates saved device , doesn't use computer's location.

click on "more" option on righthand sidebar, should open "extended controls" window. select "location" tab (it should selected default) , change latitude , longitude inputs heart's desire , click "send". voilà!
