[mono-android] Error in loading the Mono.Cairo Library

[Pritish]

Now this time I am using the *Mono.Cairo*.Matrix dll in my monoandroid
application to load the some System.Drawing.Drawing2D.Matix Class Methods it
works fine at build time  but at run time the Matrix class from Cairo.Matrix
gives an error* "System.NullReferenceException: Object reference not set to
an instance of an object."*
                 when I intialize the Cairo.Matrix Class error is "Exception
in loading dicom filelibcairo-2.dll."  

   This below code I am trying.......... 
using System; 
using System.Drawing; 
using Medsynaptic.Common; 
using Medsynaptic.Imaging1.Mathematics; 
*using Matrix = Cairo.Matrix;*

public class SpatialTransform : ISpatialTransform 
    { 
private * Cairo.Matrix _cumulativeTransform; * 
        private * Cairo.Matrix _transform*; 
public PointF ConvertToDestination(PointF sourcePoint) 
        { 
            double x = 0.0, y = 0.0;               
            this*.CumulativeTransform.*TransformPoint(ref x, ref y);                     
            PointF point = new PointF((float)x, (float)y); 
            return point; 
        } 
 *Here it show Null Ref Exception:Object reference not set to an instance of
an object*
public Cairo.Matrix * CumulativeTransform    *   
        {             
            get 
            {                 
                Calculate(); 
                return _cumulativeTransform; 
            } 
        } 
 protected virtual void Calculate() 
        { 
            if (!this.RecalculationRequired) 
                return; 
           *   ERROR @ if condition:- Object reference not set to an
instance of an object*
            if (*_cumulativeTransform* == null) 
                _cumulativeTransform = new Cairo.Matrix(); 

           // _cumulativeTransform.Reset(); 

            _cumulativeTransform.InitIdentity(); 
} 
} 

these are some screen short for more understanding
