I'm trying to display notification in test application (example 'HelloWorld (console)'), but there is no notification shown. Where i'm wrong? What i've miss?

[BGmot]

what if you remove render()?

// render();

[AlexXF]

No. It does not helps. No any notifications shown.

There is no example, so i do not understand - where i'm wrong. All looks good, but...

[BGmot]

Just a guess - probably you should not destroy message prior to cancelling notification:

// notification_message_destroy(&pMessage);

[AlexXF]

No, it does not helps too.

[BGmot]

I know, it's not funny.. but probably you are missing 

notification_request_events(0)

in main() prior to trying to notify?

[AlexXF]

Does not matter. Trying to add notification_request_events(0), but this is not helps. This function needs if i need to process user responce on notify.

Hi AlexXF,

When I inserted "notification_message_add_prompt_choice()" in your code before calling

notification_alert(), I was able to trigger a notification dialog appear.

According to https://developer.blackberry.com/native/beta/reference/com.qnx.doc.bps.lib_ref/com.qnx.doc.bps.lib_r...

notification_message_set_title() itself shall be enough to trigger a toast message( did not work for me as well)

We are consulting our internal contact to get clarification for the conditions of triggering a toast message for notication.

[AlexXF]

I'm using NDK Beta 2 (10.0.6) and Firmware 10.0.6.545.

If I add this code before notification_alert it does not helps.

    if(notification_message_add_prompt_choice(pMessage, "Ok", NULL)!=BPS_SUCCESS)
    {
        fprintf(stderr, "Unable to notification_message_set_type\n");
    	notification_message_destroy(&pMessage);
    	return;
    }
    if(notification_alert(pMessage) != BPS_SUCCESS)
    {
        fprintf(stderr, "Unable to notification_alert\n");
    	notification_message_destroy(&pMessage);
    	return;

    }

[AlexXF]

Can you attach example of WORKING code?
