BoundingBox Shape

Issue

In my Android mapping activity, I have a parallelogram shaped area that I want to tell if points (ie:LatLng) are inside. I've tried using the:

 bounds = new LatLngBounds.Builder()
                   .include(latlngNW)
                   .include(latlngNE)
                   .include(latlngSW)
                   .include(latlngSE)
                   .build();

and later

 if (bounds.contains(currentLatLng) {
    .....
 }

but it is not that accurate. Do I need to create equations for lines connecting the four corners?

Thanks in advance.

Solution

The LatLngBounds appears to create a box from the points included. Given the shape that I'm trying to monitor is a parallelogram, you do need to create equations for each of the edges of the shape and use if statements to determine which side of the line a point lies.

Not an easy solution!
