Inserting Firebase Date Field On SQLite As String With SimpleDateFormat

I am receiving a child change from Firebase, but when I insert into SQLite, it gives me a warning. The insertion was success, but how do I fix this warning? W/ClassMapper: No sette

Solution 1:

It looks like you're expecting this Firebase object:

"data_validade" : {
  "date" : 29,
  "day" : 0,
  "hours" : 10,
  "minutes" : 34,
  "month" : 0,
  "seconds" : 36,
  "time" : 1485693276834,
  "timezoneOffset" : 120,
  "year" : 117
}

To map to this field:

private Date data_validade;

The warnings come from the fact that Date has no setDay() and no setTimezoneOffset() to match those fields in the object. Really, this is not the best way to store a date in Firebase.

If you want to store a date in Firebase, just use a long integer. If you then need to convert that to a Date, just create a new Date with "new Date(long)". If you need to convert a Date into a long, use date.getTime().
