HI Yuriy, Another question here. I am not sure about how is the show notification WHEN_CLOSED_OR_IN_BACKGROUND working (as well as ALWAYS). The scheduled notifications is working fine when the process is not killed (force stopped). The notification is working fine, either in background, or even triggered Application.Exit(). However, the notification is not working when the application is forced stopped. I want to have my application firing notification like how alarm application does. For example, when you set an alarm via clock application, you can force stop the clock application with the alarm still working in background (where I believe they develop clock application with the service class). Is your UTNotification plug-in able to do the same thing? Or am I doing something wrong here? Thanks in advance.
