Use parcelable to store item as sharedpreferences?

Question

I have a couple objects, Location, in my app stored in an ArrayList and use parcelable to move these between activities. The code for the object looks like this:

Answer 1

Since parcelable doesn't help to place your data in persistent storage (see StenSoft's answer), you can use gson to persist your Location instead:

Saving a Location:

val json = Gson().toJson(location)
sharedPreferences.edit().putString("location", json).apply()

Retrieving a Location:

val json = sharedPreferences.getString("location", null)
return Gson().fromJson(json, Location::class.java)

In case you're still using Java, replace val with String, Gson() with new Gson(), ::class.java with .class and end each line with a semicolumn.
