ObservableInt causa l'arresto anomalo nella libreria DataBinding

Question

Stavo giocando con la nuova libreria di associazione dati e ho provato a implementare l'interfaccia osservabile. Ma continua a bloccarsi, non importa se imposto la variabile age su textview o meno. Il codice funziona bene se converto la variabile di età in stringa. C'è un modo per farlo funzionare con int?

public class User extends BaseObservable { 

@Bindable 
public final ObservableField<String> name = 
     new ObservableField<>(); 
@Bindable 
public final ObservableInt age = new ObservableInt();} 

registro dei crash:

}

Mettere questo tag dati

È necessario utilizzare @ {String.valueOf (user.age)} in TextView.

O @ {"" + user.age}
