... I want to fill this collection from data coming from web service because I want to insert this data to my Sqlite database.

Right. The serialization error message is misleading. You are trying to create a foreign collection and you can't call the constructor directly. You should instead be calling

dao.assignEmptyForeignCollection(data, "entitiyCollection");

or

data.entitiyCollection = dao.getEmptyForeignCollection("entitiyCollection");

This wires the appropriate DAO object into the foreign collection. I've improved the javadocs and the error message.
