How to pass a SortedSet as an Intent's extra?
<p>I have a service that produces as result a <code>SortedSet</code> object. I need to pass it to another <code>Intent</code> that will use it. First is put in the notification area, then when the user actions it it will need to fire the activity.</p>

<p>As it it's own SortedSet is not <code>Parcelable</code> nor <code>Serializable</code> so it won't work. One single item in <code>SortedSet</code> is already parcelable and it's used fine, but I need the whole set.</p>

<p>How to pass a <code>SortedSet</code> as an Intent's extra?</p>
