Android Question Please help in GPS

[agasca]

Hello I need some help in GPS please.
Based on good examples on "GPS Tutorial / Library" and "GPS Example". I builded an APP that records for each event every 5 seconds coordinates lat, long and altitud, these data are saved into a kml file.

For one hour setup (720 events) for some unknown reason the coordinates respond rare. i.e. "When I do a dog walk" (image 1) for a short distance I can see detailed coordinates on a KML visualizer, but if I jump into the car and go "merry go round" in the city (image 2) for a longer distance I can see the detailed coordinates as straight line

Please help me to find out How could get the same "detailed coordinates" shown in a kml visualizer but not as "straight line"?
Thanks in advance.

I think you probably lost the gps fix inside the car. Try to do the same experiment keeping the device outside the windows or in a better position.

I guess that @marcick is correct. The GPS signal was lost.
