This uses the Dropbox Java SDK to share a file at "/test.txt" with a specific user:
List<MemberSelector> newMembers = new ArrayList<MemberSelector>(); MemberSelector newMember = MemberSelector.email("<EMAIL_ADDRESS_TO_INVITE>"); newMembers.add(newMember); List<FileMemberActionResult> fileMemberActionResults = client.sharing().addFileMember("/test.txt", newMembers); System.out.print(fileMemberActionResults);
<EMAIL_ADDRESS_TO_INVITE> should be replaced with the email address of the user to invite. Also,
newMembers is an array and can contain multiple users.
