android - Google MapV2 Distance Calculation -

Now I am using Google mapV2 in my application to find out the distance between 2 places (geo-digits) I'm unable and can calculate the period from which I reach the destination (by walking or driving) .. Is there any Google API available? If it does not, please guide me good tutorials? It is possible to exclude distance by using

location and Methods such as methods eg

  Location Location A = New Location ("Point A"); LocationA.setLatitude (number one latitudes); Place A.assathalata (number one songiode); Placement B = New Location ("Point B"); Place B.Setlightidue (number B lateadit); Location B.Satalagatid (number B longeoded); Dual distance = location a distance to (place B);
