Google Glass Timeline notifications for In built actions and custom actions are not working after updation(of XE-16 glass update)

Question

We have developed a google glass ware(timeline based) app. In that first we will send some timeline cards to the glass with some inbuilt menu items and custom menu items.

and we have configured the proxy url for getting notifications for time line.

It worked fine for so many days.

But After Google Glass XE-16 update we are not getting the timeline notifications

Can you please guide us inresolving the issue.

Hi Prisoner,

for inserting timeline we have used the following code:

global $base_url="http:\/\/mysite.com\/mirror"; 

$client = get_google_api_client(); 

$client->setAccessToken(get_credentials($_SESSION['userid'])); // A glass service for interacting with the Mirror API 

$mirror_service = new Google_MirrorService($client); 

    $new_timeline_item = new Google_TimelineItem();
    $new_timeline_item->setText('Hey I am testing new');

    $notification = new Google_NotificationConfig();
    $notification->setLevel("DEFAULT");
    $new_timeline_item->setNotification($notification);

    $menu_items = array();
    $custom_menu_item = new Google_MenuItem();
    $custom_menu_value = new Google_MenuValue();
    $custom_menu_value->setDisplayName("Add Item");
    $custom_menu_value->setIconUrl( $base_url . "/static/images/tulip.jpg");
    $custom_menu_item->setValues(array($custom_menu_value));
    $custom_menu_item->setAction("CUSTOM");
    $custom_menu_item->setId("add_to_cart_item"); // This is how you identify it on the notification ping
    array_push($menu_items, $custom_menu_item);
    $new_timeline_item->setMenuItems($menu_items);


    insert_timeline_item($mirror_service, $new_timeline_item, "image/jpeg", file_get_contents($base_url . "/static/images/tulip.jpg"));

for this we are trying to add new custom menus and built in menus like (pin,delete,share,send)

To subscribe to notifications we have used the Google glass Php mirror api function.

subscribe_to_notifications($mirror_service, "timeline", $_SESSION['userid'], $base_url . "/notify.php"); 

All these are working fine before XE-16 version update. After updation we are not able to get notification for time line card notifications

This is a known issue with sending image attachments. See details here:
https://code.google.com/p/google-glass-api/issues/detail?id=491

So the part of your code that has to change is:

insert_timeline_item($mirror_service, $new_timeline_item, "image/jpeg", file_get_contents($base_url . "/static/images/tulip.jpg"));  

Needs to change to:

insert_timeline_item($mirror_service, $new_timeline_item, null, null);

And use setHTML instead of setText and include an img element with a src tag that points to a web URL. E.g.:

<img src="http://example.com/static/images/tulip.jpg" />  

Note that you also have to factory reset your Glass. You can tell if you have the problem by trying to run a menu command and the spinning double arrow in the bottom right corner gets stuck and an a crash stack trace is visible on ADB logcat output on the Glass. So to fix the problem, first you have to not use image attachments, and second you have to reset the Glass to fix the broken timeline sync on the Glass.
