How to make class with multiple Integers and Strings Parcelable?

I have following

Class
and i want to make it
Parcelable

Problem is that when i read
isHidden and Counter
variable from
int[] arraySongIntegers
by method
in.createIntArray()
, i am getting an empty array of size 0 and BTW all the String variables are being read correctly . Please tell me how do i write all variables to
Parcel
and read it back properly.

public class Song implements Parcelable{
public static long firstSongId;
private long id;
private String title ,mimeType, artist , dateAdded ,album;
private int isHidden ,counter; // 0 is false , 1 is true

public Song(Parcel in){
readFromParcel(in);
}

@Override
public void writeToParcel(Parcel dest, int flags) {
int[] arraySongIntegers = new int[2];
arraySongIntegers[0] = isHidden;
arraySongIntegers[1] = counter;
dest.writeIntArray(arraySongIntegers);


dest.writeLong(id);

List<String> l = new ArrayList<>();
l.add(title);
l.add(artist);
l.add(album);
l.add(dateAdded);
dest.writeStringList(l);

}


public void readFromParcel(Parcel in){

id = in.readLong();

int[] arraySongIntegers = in.createIntArray();
isHidden = arraySongIntegers[0];
counter = arraySongIntegers[1];

ArrayList<String> list = in.createStringArrayList();
title = list.get(0);
artist = list.get(1);
album = list.get(2);
dateAdded = list.get(3);
}

public static final Parcelable.Creator CREATOR =
new Parcelable.Creator() {
public Song createFromParcel(Parcel in) {
return new Song(in);
}

public Song[] newArray(int size) {
return new Song[size];
}
};


}

Thanks in advance.

In addition to my comment (there's no reason to make it an array)- you need to read everything in the order you write it. By reading the id first everything gets screwed up.
