Reading and writing integer array to parcel

Question

I could not find any solution for how to treat with integer array in case of parcel (I want to use these two functions dest.writeIntArray(storeId); and in.readIntArray(storeId);).

Here is my code

public class ResponseWholeAppData implements Parcelable {     private int storeId[];      public int[] getStoreId() {         return storeId;     }      public void setStoreId(int[] storeId) {         this.storeId = storeId;     }      @Override     public int describeContents() {         return 0;     }      public ResponseWholeAppData(){         storeId = new int[2];         storeId[0] = 5;         storeId[1] = 10;     }      public ResponseWholeAppData(Parcel in) {          if(in.readByte() == (byte)1)               in.readIntArray(storeId);  //how to do this storeId=in.readIntArray();  ?                                   }      }      @Override     public void writeToParcel(Parcel dest, int flags) {         if(storeId!=null&&storeId.length>0)                            {             dest.writeByte((byte)1);             dest.writeIntArray(storeId);         }         else             dest.writeByte((byte)0);      }     public static Parcelable.Creator<ResponseWholeAppData> getCreator() {         return CREATOR;     }      public static void setCreator(Parcelable.Creator<ResponseWholeAppData> creator) {         CREATOR = creator;     }      public static Parcelable.Creator<ResponseWholeAppData> CREATOR = new Parcelable.Creator<ResponseWholeAppData>()             {         public ResponseWholeAppData createFromParcel(Parcel in)         {             return new ResponseWholeAppData(in);         }         public ResponseWholeAppData[] newArray(int size)         {             return new ResponseWholeAppData[size];         }             };       }

When I use "in.readIntArray(storeID)", I get an error:

"Caused by: java.lang.NullPointerException at android.os.Parcel.readIntArray(Parcel.java:672)".

Instead of using "readIntArray" I used the following:

storeID = in.createIntArray(); 

Now there are no errors.
