android - Nested Parcelling : RuntimeException - Unmarshalling unknown type code 3211319 at offset 440 -

i need send data activity, may running in different context. created class a, has arraylist of datatype b 1 of instance member . declared class b class a's inner class. send class a's instance through intent, made class , b both parcelable.

class structure (this not include complete code e.g. code written make classes parcelable):

public class implements parcelable{     public class b implements parcelable{          public arraylist<string> value;          ....          ....            public void writetoparcel(parcel dest, int flags) {             dest.writelist(value);            }         ....         ....    }     public list<b> group;    public string name;     ....    ....      public void writetoparcel(parcel dest, int flags) {         dest.writelist(group);         dest.writestring(name);        }    ....    .... } 

i used putextra (string name, parcelable value) function put data.

but on receiving side, got following exception:

then moved class b, outside class (as thought may problem of inner class, , declared creator static. static declaration not present when class b inner class of class a). did not helped.

this seems problem due nested parceling.

any suggestion ??

note: when used android.os.bundle.putparcelable(string key, parcelable value) function of bundle class, , unmarshalled using android.os.bundle.getparcelable(string key) fine. seems problem respect intents only.

did include creator in both?

public static final parcelable.creator<a> creator = new parcelable.creator<a>() {    public createfromparcel(parcel in) {       return new a(in);       }     public a[] newarray(int size) {       return new a[size];       } }; 

& constructors take parcel:

public a(parcel parcel) {    name = parcel.readstring();    //etc.. } 

?
