Android Facebook events invite

Question

I'm developing an android application where I have to invite facebook friends to an event using Rest API.

Below is the code where I prepare bundle of parameters

   Bundle eventInviteParams = new Bundle();
   eventInviteParams.putString("method", "events.invite");
   eventInviteParams.putString("eid", event.getFacebookEventId());
   eventInviteParams.putString("personal_message", "Sample message");

   String userIds = "";
   for (int i = 0; i < facebookAdapter.getCount(); i++) {
    FacebookUser user = facebookAdapter.getItem(i);
    if (user.isSelected()) {
        userIds += user.getId() + ",";
    }
   }
   if (userIds.length() > 0) {
    userIds = userIds.substring(0, userIds.length() - 1); // to remove last comma
    eventInviteParams.putString("uids", userIds);
   }

Then

response = mFacebook.request(eventInviteParams);

where mFacebook is Facebook api object.

The response is always

{"error_code":200,"error_msg":"Permissions error","request_args":[{"key":"uids","value":"XXXXXXXXX,XXXXXXXXX"},{"key":"method","value":"events.invite"},{"key":"format","value":"json"},{"key":"eid","value":"XXXXXXXXXXX"},....]}

Application has following permissions

"email","publish_stream","read_stream","create_event","offline_access","user_events","friends_events","rsvp_event"

I want also to mention that I'm not event creator. I have searched on FCB docs and google but cannot find a proper answer.

Answer 1

Thank you very much for your response. I continued with research and I found that the error

"error_code":200,"error_msg":"Permissions error"

was because I was not following the event. Once I RSVP to the event, I got the response false (I don't know why) and the error gone. I checked in Facebook and the given people were invited.

thanks
