buongiorno,
sto cercando di usare ActiveAndroid,ma senza riuscirci.
Il mio progetto รจ composto da delle Activity con View per richiedere i
dati da caricare nel DB, e da una Activity senza View per caricare i dati
sul DB con il metodo save() del package ActiveAndroid.
di seguito il mio codice che va in errore:
package com.example.danilo.genealogia3;
import com.activeandroid.ActiveAndroid;
/**
* Created by danilo on 06/12/16.
*/
public class insert extends android.app.Application{
String nome;
String cognome;
Gana gana;
public insert(){
}
public String setValues(String Value1,String Value2,String Value3,String
Value4,String Value5,String Value6) {
cognome=Value1;
nome=Value2;
System.out.println(cognome);
System.out.println(nome);
System.out.println(Value6);
System.out.println(Value3+"/"+Value4+"/"+Value5);
ActiveAndroid.initialize(this);
gana = new Gana();
gana.tiprec = "N";
gana.cognome = cognome;
gana.nome = nome;
gana.ggN = Value3;
gana.mmN = Value4;
gana.annoM = Value5;
gana.luogoNascita = Value6;
gana.save();
return("FATTO");
}
}
Questo lo stack di errore:
