What is the fastest way to save set of strings in SharedPreferences?

Question

I have 2 data sets

String[] wordsArray;
Queue<String> wordsQueue;

They store the same data, around 500 strings each, 1-3 words per string. I need to save one of them to SharedPreference. What is the best (fastest) way to do it?

Now I just use

Set<String> mySet = new HashSet<String>(wordsQueue);
edit.putStringSet("Words", mySet);

But it works slower than I want.

i'm new to java and still not familiar with threads. Anyway, I will try to do it in this way thanks for advice. — Gaijin, Jan 14 '17 at 16:55

Use apply() instead of commit() which will save the preference in a background thread (i.e. asynchronous).

Set<String> mySet = new HashSet<String>(wordsQueue);
edit.putStringSet("Words", mySet).apply();

For saving the array of String in SharedPreference you might consider doing something like this stated in this answer.

Thank you! I guess I just need to read official docs more attentively, ha-ha. – Gaijin Jan 14 '17 at 17:06
But is there any way to do the same thing without copying original list to HashSet? – Gaijin Jan 14 '17 at 17:06
