Answer 1

This is not an answer, but note the signature for the Location constructor is Location(String provider).

i.e. the String you pass to the constructor should be one of LocationManager.GPS_PROVIDER, LocationManager.NETWORK_PROVIDER or LocationManager.PASSIVE_PROVIDER, not "point A" and "point B".
