 You can calculate the distance using this code. Here in the distance meter you can call this function and check whether the location is or not. 
 
  Private Boolean check Fourieria (Intra rad, wave long form position, wave long to position) {place location A = new location ("Point A"); LocationA.setLatitude (fromPosition.latitude); LocationA.setLongitude (fromPosition.longitude); Location Location B = New Location ("Point B"); LocationB.setLatitude (toPosition.latitude); LocationB.setLongitude (toPosition.longitude); Int distance = (int) locationadress to (location b); If (distance / 1000 & lt; = rad) is right back; Second false return; }
