Answer 1

I was having this problem, because I was also initializing my list with Arrays.asList:

List names = Arrays.asList("a", "b", "c");

To solve the problem, I used addAll instead:

List names = new ArrayList();
names.addAll(Arrays.asList("a", "b", "c"));

This way you can edit the list, add new items or remove.
