/**
|
|
* Name: WindowsPhonePush
|
|
* Description: Enable push notification to send information to Friendica Mobile app on Windows phone (count of unread timeline entries, text of last posting - if wished by user)
|
|
* Version: 2.0
|
|
* Author: Gerhard Seeber <http://friendica.seeber.at/profile/admin>
|
|
*
|
|
*
|
|
* Pre-requisite: Windows Phone mobile device (at least WP 7.0)
|
|
* Friendica mobile app on Windows Phone
|
|
*
|
|
* When plugin is installed, the system calls the plugin
|
|
* name_install() function, located in 'addon/name/name.php',
|
|
* where 'name' is the name of the addon.
|
|
* If the addon is removed from the configuration list, the
|
|
* system will call the name_uninstall() function.
|
|
*
|
|
* Version history:
|
|
* 1.1 : addon crashed on php versions >= 5.4 as of removed deprecated call-time
|
|
* pass-by-reference used in function calls within function windowsphonepush_content
|
|
* 2.0 : adaption for supporting emphasizing new entries in app (count on tile cannot be read out,
|
|
* so we need to retrieve counter through show_settings secondly). Provide new function for
|
|
* calling from app to set the counter back after start (if user starts again before cronjob
|
|
* sets the counter back
|
|
* count only unseen elements which are not type=activity (likes and dislikes not seen as new elements)
