Android Question How can i get notification from database

[Makumbi]

Please help i have a database which sends out messages . but i wanted to get the notification on my app even before opening it. because right now i can only get the notification after i have opened the app . how possible can i do this using b4a

via Firebase Cloud Messaging (FCM) you can send a notification to a device, then when you click it the app (re)open.
or a app+service combination run non stop at your device. much battery consume.
or a app+timer triggered service starts and poll for messages. no real time messages.

You are free to store the notiificationdata in a DB instead of showing a Notification when the notification comes in...

Or what exactly is the question?

Edit
Sorry, i do have makumbi on my Ignorelist. For me it looks like your post is the first post. I now realized that you are giving a answer here. So the above should go to @Makumbi
