[android-developers] LocationManager speed

I have a KML file that I feed to the emulator through the DDMS
emulator control. The latitude and longitude values come through just
fine, but the thing never has any speed (doing a
LocationManager.hasSpeed() is always false as is getSpeed() always
0.0).

Is there some sort of trick you have to use to get the emulator to
recognize speed?

Note that I added a method to calculate the speed based on the math
involved between the last lat/long coordinate and the current one
along with the change in time in between the two readings, but I
THOUGHT this wouldn't need to be done and that I should be able to
rely on LocationManager.hasSpeed and getSpeed in the real world.
