public async bool request_contact_info_async (Cancellable? cancellable) throws Error
Requests an asynchronous request of the contact info of this.
When the operation is finished, callback will be called. You can then call
request_contact_info_async.end to get the result of the operation.
If the operation is successful, the contact_info property will be
updated (emitting "notify::contact-info" signal) before callback is called. That means you can call
get_contact_info to get the new vCard inside callback
.
Note that requesting the vCard from the network can take significant time, so a bigger timeout is set on the underlying D-Bus call.
cancellable can be cancelled to free resources used in the D-Bus call if the caller is no longer interested in the vCard.
If CONTACT_INFO is not yet set on
this, it will be set before its property gets updated and callback is called.
