GPS Route Simulator seems to fit the bill.
it is used to simulate routing when developing other software.
The description says:
Are you tired of developing location aware apps and having to program your own
GPS simulator? Do you want to cheat on foursquare, facebook, Tinder and whatsapp?
Use this application to simulate gps locations, routes or even KML files.
-Define a static point location or a radius to jump on intervals
and watch how other apps believe that the position is correct.
-Search for a route between two points and simulate
that you are following it.
-Upload a KML file to /sdcard/kml and simulate it's route
in the time specified.
Of course, if anyone is seriously looking at your location data, then after awhile they are going to notice the repetitiveness ...
