I have a String Array from a server and I want to save the string array in sharedPreferencesto avoid further server calls to retrieve the string array.

This is my String array below:

String[] names = new String[response.body().getData().size()];

SharedPreferences.Editor editor = prefs.edit();
editor.putStringSet("walletTypes", names);

Unfortunately I can't put the String Array in a StringSet, anybody have an idea how I can save my String array in SharedPreferences.

Do you have any errors? Did you called apply() or commit() on the editor after putting the array? – Cata Aug 29 '17 at 12:54

Convert your string array to json string using GSON and put it in preference – Akshay Bhat 'AB' Aug 29 '17 at 12:55
the error says wrong second argument type. Found java.lang.String[] Required java.util.Set – Lending Square Aug 29 '17 at 13:02
@Cata yes i call commit() – Lending Square Aug 29 '17 at 13:03
BTW, your `names` array still empty?! you only created array with size equal to response size, but no content ?! is that what you want? – Yazan Aug 29 '17 at 13:15

other than that, have you checked this ? https://stackoverflow.com/questions/3064423/how-to-convert-an-array-to-a-set-in-java – Yazan Aug 29 '17 at 13:17
The error says it all, you need a set of String objects and not an array there. You need to change the array to a Set. To do that (if you don't know), take a look here: https://stackoverflow.com/questions/3064423/how-to-convert-an-array-to-a-set-in-java – Cata Aug 29 '17 at 13:23
