Hi Ahlem,
Please try do the next steps

  • get user relations by its id
  • get the value of total objects of the relations
StringBuilder whereClause = new StringBuilder();
whereClause.append( "User[Diplomats].objectId='" ).append( "YOUR_USER_ID" ).append( "'" );


BackendlessDataQuery dataQuery = new BackendlessDataQuery();
dataQuery.setWhereClause( whereClause.toString() );


Backendless.Persistence.of( Diplomat.class ).find( dataQuery,
new AsyncCallback<BackendlessCollection<Diplomat>>()
{
@Override
public void handleResponse( BackendlessCollection<Diplomat> relatedDiplomats )
{
relatedDiplomats.getTotalObjects();
}
@Override
public void handleFault( BackendlessFault fault )
{
System.out.println(fault.getMessage());
}
}
);
