Application activity events from your friends will be shown on your Home Page and on your Friend Update page. Your Home Page will show a maximun of 50% of application events, and you will compete for this real estate with your fellow application developers. There is not much control you have in this area.

You can also retrieve your events from your own application and show this on the application canvas page or on the profile page. Here is a little code sample that uses some jQuery to render the results:

 <div id="activiesFeed">.</div><div id="feedTxtToHtml">.</div>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"></script>
<script>

   if (showViewer) {
     idspec.setField(opensocial.IdSpec.Field.USER_ID, opensocial.IdSpec.PersonId.VIEWER);
   } else {
     idspec.setField(opensocial.IdSpec.Field.USER_ID, opensocial.IdSpec.PersonId.OWNER);
   }

function processActivities(response){
  try {
   var activitiesData = MyOpenSpace.RequestType.FETCH_ACTIVITIES;
   if (response.hadError() || response.get(activitiesData).hadError()) {
     if (response.get(activitiesData).getErrorCode() == opensocial.ResponseItem.Error.UNAUTHORIZED) {
           $("#status").html("Unauthorized; requesting user for permission.");
           requestUserToReceiveActivities();
           return;
     }

     if (response.get(activitiesData).hadError()) {
         $("#status").html("Error getting activities");
         $("#status").append(response.get(activitiesData).getErrorCode());
         $("#status").append(response.get(activitiesData).getErrorMessage());
     }
     $("#status").append(response.getErrorMessage());
  } else {

var receivedData = response.get(activitiesData).getData();
$("#activiesFeed").append("<ol>");
 for (var item in receivedData.asArray()) {
   var timeTxt = receivedData.asArray()[item].getField("postedTime");
   // note: iconUrl is missing, but that would just be your regular icon for the app.
   var iconUrl = receivedData.asArray()[item].getField("streamFavIconUrl");
   var userId = receivedData.asArray()[item].getField("userId");
   var titleId = receivedData.asArray()[item].getField("titleId");
   var appId = receivedData.asArray()[item].getField("appId");
   var titleTxt = receivedData.asArray()[item].getField("title");
   var bodyTxt = receivedData.asArray()[item].getField("body");
   var oneUpdate = "";
    if (bodyTxt != null && bodyTxt.length > 0){
       oneUpdate = "<li> on " + timeTxt.substring(0,16) + ": <div>" + $("#feedTxtToHtml").html(titleTxt).text() + "<br/>" + $("#feedTxtToHtml").html(bodyTxt).text() + "</div></li>";
    } else {
       oneUpdate = "<li> on " + timeTxt.substring(0,16) + ": <div>" + $("#feedTxtToHtml").html(titleTxt).text() + "</div></li>";
    }

   $("#activiesFeed").append(oneUpdate);
 }

$("#activiesFeed").append("</ol>");

//make sure all hyperlinks get out of the iframe
$("#activiesFeed a").attr("target", "_blank");
 //hide the helper dom object.
$("#feedTxtToHtml").hide();
}

}

catch (any){
  $("#status").html("<span style='color:red'>ERROR with rendering the feed.</span>");
 }

}

function requestUserToSentActivities(){
  opensocial.requestPermission([MyOpenSpace.Permission.VIEWER_SEND_UPDATES_TO_FRIENDS], "Let your friends know what you are doing.", checkPermissionResponseSent);
}

function requestUserToReceiveActivities(){
  opensocial.requestPermission([MyOpenSpace.Permission.VIEWER_SHOW_UPDATES_FROM_FRIENDS], "See what your friends are doing with this app!", checkPermissionResponseReceive);

 Hi Marco,

I am facing the same issue that you have mentioned here for  opensocial.requestPermission. The callback function is not being called. Any idea when this feature will be implemented fully

Regards

Sashi

 I am also having problems with requestPermission not executing my callback.  Is that a known issue that's being fixed?

The call back functions are working fine.

It turned out that the OpenSocial container 'eats' the alert statements. I will modify my code sample.

In my demo app I changed the code to log the meggage to the Firebug console. 

See the app here: http://www.myspace.com/427516622

the app is not working..

 the code below is not working..

 Hi Vishnu,

Are you still having a problem with this?

Rhonda

 Rhonda,

Please confirm whether this is fixed for  opensocial.requestPermission also or for only activities.
