java - Why I am gatting getting Parcelable encountered IOException when try to pass an Interface object through intent -

i trying pass interface object through intent.

public interface ilockkeyconfig extends serializable{    public void onkeyconfigchage(); }   // doing in activity  intent intent = new intent(lockscreensettings.this,buttoncustomization.class);             ilockkeyconfig ilockkeyconfig = new ilockkeyconfig() {                  @override                 public void onkeyconfigchage() {                     system.out.println("onkeyconfigchage called");                  }             };             object[] keconfig = {lockscreenkeylist.get(position),ilockkeyconfig};             intent.putextra("keyconfigobj", keconfig);             startactivity(intent);   //and in activity b doing... private void getintentdata() {     object[] keyconfigobj = (object[]) getintent().getserializableextra("keyconfigobj");     keyconfig = (keyconfig) keyconfigobj[0];     ilockkeyconfig = (ilockkeyconfig) keyconfigobj[1]; } 

but above code getting following error:

`06-27 15:18:04.648: e/androidruntime(5483): java.lang.runtimeexception: parcelable encountered ioexception writing serializable object

what going wrong here?

you either implement parcelable or put serialized objecs arraylist. arraylist implements serializable , accept long arraylist have serializable objects.

putextra(string name, serializable value) 

or

public intent putextra (string name, parcelable[] value)
