Issues in Geofencing in Android

I am working with Geo-fencing in Android. I am able to draw a polygon on a map and get the latitude and longitude values of the vertices. My question is how can I determine when the user enters the polygon? Is there any way to determine whether the user is inside or outside the polygon?

A bit late answer but you might use android-maps-utils which has a PolyUtil class containing the following method:

// Computes whether the given point lies inside the specified polygon.
static boolean containsLocation(LatLng point, List<LatLng> polygon, boolean geodesic)

You can use the Google Play Services Geofencing API launched in IO 2013 to do this quite easily.

Check out creating and monitoring geofences in the developer docs for a complete tutorial. Especially the handle geofence transitions section.
