Push Notification Get Lost Message ID List
Kalipso - Form - Actions - Actions Description - Group Communications - Push Notification Get Lost Message ID List
Retrieves the number of push notification messages and the corresponding IDs that where received while your application was not active and that are currently stored locally on the device.
Action available for the following operating systems:
Parameters
Unique IDs List string - The control or variable where to save ID list of the lost messages.
Number of Items numeric - The control or variable where to save the number of los messages currently stored.
Items Separator string - The control or variable where to save the sender of this message.
If a message is received and your application is not running, the O.S. will make the appropriate display of the message, and if you enabled the "Save messages when application is not active" option in your project properties, it will be saved locally on the device. You can use "Push Notification ... Lost ..." actions to retrieve the messages that where received while your application was not active.
Lost Messages are also saved if the event Push Notification Received is not executed for a specific message. (Application is closed or application is open but the event is not handled neither by the current nor the first form).
Lost messages are mainly for data messages. Notification messages will normally not be captured. (On Android if application is open, they may be captured, because there is no way to tell them apart). If you want to handle lost messages, but also send a user notification, send 2 messages, one data message that will be saved if the app is closed, and one notification message so the user can be notified.
