If my device don't have internet connection and I have send 100 Push message to my device then how many message I will received after the connection comes online and What is maximum limit of apple push notification if device have no internet connection?
If APNs attempts to deliver a notification but the device is offline, the notification is stored for a limited period of time, and delivered to the device when it becomes available.
Only one recent notification for a particular app is stored. If multiple notifications are sent while the device is offline, each new notification causes the prior notification to be discarded. This behavior of keeping only the newest notification is referred to as coalescing notifications.

I want get wake up notification of my device to my server.
I've android device that when its closed I want my server get notification that message arrived. I dont need the mesage itslef just to know that there is message coming to my device. is it possible ?
When I send multiple notifications to Apple or Android devices through MFP, Apple devices will receive all the notifications on the other hand Android will only receive the last notification. We are using Unicast Notification to send messages to user devices using this REST API.
Android devices will also receive all the push notifications sent by the MFP server. The notification shade ( center) will however display only the last received. This does not mean the earlier ones are lost. They are all still available, just not visible in the notification shade.
You have not mentioned the complete build version of your MFP. To see all the notifications in the shade-
install the latest ifix from FixCentral, rebuild your application. Edit your wlclient.properties and add the following property-
showAllNotificationsInTray=true
I have setup WSo2 EMM correctly. Noticed that device information and Get All Applications Notifications go pending and are never delivered to the devices. The status of these notifications in the database table is also P.
The only way to deliver these messages are by pushing the Camera Enable/Disable Operation or some other notifications, then the older pending notifications get delivered.
Seems they are stuck. This also happens to policy enforcement notifications. I have to manually push camera disable/enable to make these works.
Why does this happen? The notifications should be delivered instantly, like they do in Camera Enable/Disable case.
I am connected in Production Mode. Any pointers to sort this out?
I was using Java 1.6 earlier. Once I switched the JDK to 1.7, it appears to so far work well.
My question is as follows:
I have a database on another server with the appropriate records of the devices.
I can send a notification by REST API without necessarily making an installation registry?
Something like:
"Send notification to the following devices:
- id1
- id2
- Id3 "
My idea is to continue to use my other server without getting spending requests or hosting Parse. Only use the push notifications service.
Is it possible?
Not sure what types of devices you are referring to (iOS? Android? Windows Phone?), but push notifications to mobile devices always require an application to be installed on the target device, since the notification is sent to a specific application on a specific device.
And the only way you can get a device ID (which you can use to send push notification to a device) is by having an application on the device send that ID to your server after obtaining it from the relevant push notifications service (APNS for iOS, GCM for Android, etc...).
I'm developing an app which relies on C2DM to be notified of some new data to be fetched from a REST service. I have successfully implemented the C2DM android feature, but the behavior over Wifi is different from the connection over 3G. The messages are received instantly over 3G, but I have to manually turn Wifi off and on to have a "grace period" of ~1 min in which I receive them instantly.
My question is: Is there any way I can programmatically restart the connection, or trigger the notification fetch?
EDIT:
I've implemented an AsyncTask that periodically "reassociates" the connection to the access point (using WifiManager.reassociate()) every minute and a half. Not so sure about the correctness of this solution, though.
I've seen similar issues. It seems that under some circumstances C2DM messages are not delivered over wifi connections, when they are over 3G. On a related note I've also seen Android devices "drop" the push connection, so messages are not delivered (in my case the solution can be to put the device in airplane mode and then turn the network back on).
This reinforces the fact that all applications that use C2DM should be built so that even if push messaging fails, the app still works (even if messages/updates are slower because there's occasional polling to the server)
I wouldn't personally want to mess with the wifi connection as that's something that may cause problems for the user.
