Android Question Check GPS-Location

Hi,

I have on a route specific GPS coordinate I must necessarily go. How can I check if I have reached the individual point while driving by car?

I know you can measure the distance with location1.distanceTo (location2) - but is not so safe. For example, if the point is after a curve, then the distance from point to point is less than the real distance.

Thanks in advance

Unfortunately, this is inaccurate for a car race. :(
Can I use the library "GoogleMaps" and measure the distance to the point at each GPS1_LocationChanged?
Or is it not recommended?

Is the race route the same as Google Maps route?
Maybe you consider a timer and then poll your new location and measure the new distance.
exactly like you did with the red route.

Yes, it should be the same and I need to check it out as well. ;)
I am currently doing it with the web service.
When testing with 2 participants and it works quite well, I do not know how the web service, with 50-70 Teilnemer, behaves. :(
