I have a Google Map fragment on my android application.
I have markers drawn on the map which represent places of interest and I have an extra functionality that draws a circle on the center with a radius defined by the user.
What I want to do is that only the markers which are contained inside this circle shall be displayed on map. I am using the Circle object, from Google maps Shapes, to draw the circle.
The problem is that, although the center of the circle is defined in Latitude/Longitude coordinates, it's radius is defined in meters. So how can I calculate if a position of a place in LatLng is contained within a radius defined in meters?
