OnStop Event place the code to clear cache
Java.Lang.Runtime.GetRuntime().RunFinalization();
Java.Lang.Runtime.GetRuntime().Gc();
trimCache(this.ApplicationContext);




public void trimCache(Context context)
       {
           try
           {
               Java.IO.File dir = context.CacheDir;
               if (dir != null && dir.IsDirectory)
               {
                   deleteDir(dir);
               }
               context.DeleteDatabase("webview.db");
               context.DeleteDatabase("webviewCache.db");
           }
           catch (Exception e)
           {
               CostantsLift.WriteTextFile("   trimCache ", e.Message, currDate);
               // TODO: handle exception
           }
       }
       public bool deleteDir(Java.IO.File dir)
       {
           if (dir != null && dir.IsDirectory)
           {
               String[] children = dir.List();
               foreach (string child in children)
               //for (int i = 0; i < children.Length; i++)
               {
                   bool success = deleteDir(new Java.IO.File(dir, child));
                   if (!success)
                   {
                       return false;
                   }
               }
           }
 
           // The directory is now empty so delete it
           return dir.Delete();
       }
