In GmailAdapter.java line 261, instead of
new NameValuePair
("ac", "Add+Contact&operation=Edit")
if I use :
new NameValuePair("ac", URLEncoder.encode
("Add+Contact", "UTF-8")),
new NameValuePair("operation", "Edit")
It is working.
But there is an issue with the email address encoding.
Ciao,
Richard.
