Question

i have 2 activities that share data between them:

Activity B (child)

@Override
public void onBackPressed(){
    if (miItem != null){
        Intent data = new Intent();
        Sharable sh = new Sharable(miItem);
        data.putExtra("item",sh);
        setResult(RESULT_OK, data); 
    }
    super.onBackPressed();
}

Sharable is a class that extend Parseable

Activity A (Parent)

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    if (requestCode == REQ_DIRECCIONES) //actualizamos la direccion
    {
        if (data != null){
            Sharable sh = (Sharable)data.getExtras().getParcelable("item");
            OElement item = (OElement) sh.getObject();
            //HERE!! "item" is NULL in runtime mode but not in debug mode
        }
    }
}

What is your implementation of Parcelable? I’d suggest you try using Serializable interface together with putExtra(String, Serializable) instead.
