Time for action – saving references to Objects in native Store

1. Create a new Java class com.packtpub.store.Color encapsulating an integer representation of a color. This integer is parsed from String containing HTML code (for example, #FF0000) thanks to the android.graphics.Color class:

   package com.packtpub.store;
   import android.text.TextUtils;

       private int mColor;

               throw new IllegalArgumentException();
           }
           mColor = android.graphics.Color.parseColor(pColor);
       }
       @Override
       public String toString() {
           return String.format("#%06X", mColor);
       }
   }

2. In StoreType.java, append the new Color data type to the enumeration:

   public enum StoreType {

       Color
   }
