java - UnrecognizedPropertyException after changing structure of Firebase data -

-

this question has answer here:

there little problem firebase , firebase snapshot.getvalue(mmodelclass)

i have android app wich contains user list(model class - user.java) , interacts firebase, structure:

-user --$user_id ---name ---surname

i've published app, , want update app, add new field user structure in firebase:

-user --$user_id ... --status

if it, published app crash because old model - user.java doesn't has status field , can't edit pubslished version

crash text: 

caused by: com.fasterxml.jackson.databind.exc.unrecognizedpropertyexception: unrecognized field "status" (class package.user), not marked ignorable (2 known properties: , "name", "surname"])

finally found answer: 

import org.codehaus.jackson.annotate.jsonignoreproperties;  @jsonignoreproperties(ignoreunknown = true)    public class foo {      ... }
