I don't know enough about the second problem to address it. 

For the first problem:  I would use a backend service. The users would register what they want to be notified about to the service. And the service would run a job hourly or every minute and then send a notification when whatever this event happens that requires a notification.

Since I am most familiar with Gamesparks that is what I would use, but I suspect that you can use Delephant's backend services also.

As an added benefit you can save the notification for viewing at some other time, you don't have to worry about the backend service dying on the phone or the phone being rebooted and the service not restarted.

In case I want to access the java.com website, I get the current java jre version and show it in my app, however I wanted it if in case the java version is changed on the site, I automatically receive the notification on the mobile phone in case it stays the red flag of notification in my app made in Corona, so my question is how does the app closed and without background support will receive this notification?

You would use a push notification instead of a local notification.

Now I understand, thank you very much, I will give a study on this.
