Java convert ArrayList to string and back to ArrayList?

Question

I wanted to save an ArrayList to SharedPreferences so I need to turn it into a string and back, this is what I am doing:

// Save to shared preferences
Shared         


        

Answer 1

I ended up using:

ArrayList appList = new ArrayList(Arrays.asList(appsString.split("\\s*,\\s*")));

This doesn't work for all array types though. This option differs from:

ArrayList array = Arrays.asList(arrayString.split(","));

on that the second option creates an inmutable array.
