I have two activity (A and B). Activity A launches Activity B using startActivityForResult.
From Activity B, for coming back in the Activity A I used the following code:
ArrayList<Articles> selectedArticlesList =null;
...
Intent data = new Intent();
Bundle bundle = new Bundle();
bundle.putParcelableArrayList("selected-articles", selectedArticlesList);
data.putExtras(bundle);
setResult(RESULT_OK, data);
finish();
where the class Articles implements Parcelable class.
The Activity A overrides the method onActivityResult:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if(data.hasExtra("selected-articles")){
dettServiziListCorrente = new ArrayList<Articles>();
dettServiziListCorrente = data.getExtras().getParcelableArrayList("selected-articles");
Articles a = dettServiziListCorrente.get(0);
Log.i("PRINT DESCRIPTION MEMBER", String.valueOf(a.description));
}
}
I obtain the following error:

My implementation of Articles class is:
public class Articles implements Parcelable{
public int id;
public String description;
public String immagine;
public int quantita;
public Articles (int id,String descriprion, String immagine){
this.id = id;
this.description = descriprion;
this.immagine = immagine;
this.quantita = 0;
}
public Articles (int id,String descriprion, String immagine,int quantita){
this.id = id;
this.description = descriprion;
this.immagine = immagine;
this.quantita = quantita;
}
public Articles (Parcel in){
String[] data = new String[3];
in.readStringArray(data);
this.id = Integer.parseInt(data[0]);
this.description = data[1];
this.immagine = data[2];
this.quantita = Integer.parseInt(data[3]);
}
@Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
// TODO Auto-generated method stub
dest.writeStringArray(new String[] {
String.valueOf(this.id),
this.description,
this.immagine,
String.valueOf(this.quantita)
});
}
public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
public Articles createFromParcel(Parcel in) {
return new Articles (in);
}
public Articles [] newArray(int size) {
return new Articles [size];
}
};
}
the problem is in this function:
public Articles (Parcel in)
{
String[] data = new String[3];// here you defined array of 3 elements it should be 4
in.readStringArray(data);
this.id = Integer.parseInt(data[0]);
this.description = data[1];
this.immagine = data[2];
this.quantita = Integer.parseInt(data[3]);
}
because in this line you are passing four elements:
dest.writeStringArray(new String[]
{ String.valueOf(this.id), this.description, this.immagine, String.valueOf(this.quantita) });
