Gps

I'll try to find wha't wrong with GPS options.

Geocoder implementation seems to be buggy. 

To save your position GPS and INTERNET active. Are you sure you have it enabled?

If you don't have internet connection Geocoder in Android cannot find city name based on latitude. 

I found one bug in my implementation. I'll try to release fix within next version of Fuelio (this will be 2.4).

I can confirm. There is something wrong with GPS. I'm rewriting the whole GPS classes. I hope I'll be able to fix it.
