Deleting a record

Android
1

Hellow,
My function “borraContrato” for delete a record of DatosContactos table have a problem in the second “AsyncCallback<DatosContactos>()” :
" Class ‘Anonymous class deriven from AsyncCallback’ must either be declaren abstract or implementa abstract method ‘handleResponse(T)’ in AsyncCallback’ "
void borraContacto(DatosContactos resultado) {
Backendless.Persistence.save(resultado, new AsyncCallback<DatosContactos>() {
public void handleResponse(DatosContactos nuevoResultado) {
Backendless.Persistence.of( DatosContactos.class ).remove( nuevoResultado, new AsyncCallback<DatosContactos>() {
Globales global = new Globales();
public void handleResponse(Long response) {
}
public void handleFault(BackendlessFault fault) {
System.out.println(fault.getCode());
global.error = 9;
miscontactos.finish();
global.pantallaDeRegreso = “MisContactos”;
Intent intent3 = new Intent(“apps.jmm.cat.sharemyneeds.errores”);
startActivity(intent3);
}
});
}
public void handleFault(BackendlessFault fault) {
Globales global = new Globales();
System.out.println(fault.getCode());
global.error = 9;
miscontactos.finish();
global.pantallaDeRegreso = “MisContactos”;
Intent intent3 = new Intent(“apps.jmm.cat.sharemyneeds.errores”);
startActivity(intent3);
} });
}What can I do for this problem?Thanks,

Hello!

The problem is in calling “remove” method. Change signature from remove( nuevoResultado, new AsyncCallback<DatosContactos>{…} ) to remove( nuevoResultado, new AsyncCallback<Long>{…} )
