Builds a new ACTION_CHOOSER Intent that wraps the given target intent, also optionally supplying a title. If the target intent has specified FLAG_GRANT_READ_URI_PERMISSION or FLAG_GRANT_WRITE_URI_PERMISSION, then these flags will also be set in the returned chooser intent, with its ClipData set appropriately: either a direct reflection of getClipData() if that is non-null, or a new ClipData built from getData().
Parameters:
target - The Intent that the user will be selecting an activity to perform.
title - Optional title that will be displayed in the chooser.
Returns a new Intent object that you can hand to Context.startActivity() and related methods.
