Return Squlite Value Android

I want to return the value of sqlite insert. In my code when the insert operation fail return -1 (API sqlite said: "the row ID of the newly inserted row, or -1 if an error occurred"). The problem is that always the insercion fail I recive other value in my code.

//Function in my class DAtabase
    public int insert(HashMap<String, String> queryValues,String table) {
            SQLiteDatabase database = this.getWritableDatabase();
            ContentValues values = new ContentValues();
            long result = 0;
            switch (table) {

            case "Log":
                values.put("relacion", queryValues.get("relacion"));
                values.put("objetoPadre", queryValues.get("objetoPadre"));
                values.put("objeto", queryValues.get("objeto"));
                values.put("interaccion", queryValues.get("interaccion"));
                values.put("tiempo", queryValues.get("tiempo"));
                values.put("sincro", queryValues.get("sincro"));
                result=database.insert("Log", null, values);    
                database.close();
                System.out.println("Value:"result);
                return (int) result;//result here is -1
            case "Conf_spinner":
                values.put("relacion",queryValues.get("relacion"));
                values.put("interaccion",queryValues.get("interaccion"));
                database.insert("Conf_spinner", null, values);
                database.close();
                System.out.println("Value:"result);//result here is -1
                return (int) result;

            default:
                database.close();
                return 1;
                break;
            }
        }

This part of the code return -1 if the insercion fail or other value in other case.

Here is where i have problems

//Code of my android activiy
    int value = myDatabase.insert(queryValues, "Conf_spinner");

    if(value==-1) //value always set other number that isn't -1.
       showMessaging();
    else
    Log.e("MyTag","FAIL INSERCION");

Tkans for the help
