You are not adding the argument required, called x.

In the changed procedure, you have to add it the arguments which is present in the original DataChanged Event Block.

But i do not see notification id0, as if eventName "FirebaseDB1.DataChanged" never do procedure "changed". If i debug and put notification to the "sequence" they are popup but inside "changed" no

Now i edit code and if i turn on the app all works fine (if i edit tag in database, id0 popup) but if i close app i have only Checking... and no popup id0 when i edit tag in database. (i edit "changed" name because in upper version i have big C on procedure :P)

It never calls the "changed" procedure because your procedure declaration is incorrect, it should be this way:


I use it, but still only if i have open app working, when i close do not have popup. Maybe i wrong write eventName or something still do not go to "changed" procedure

Do you mean it stops working when you close the app?

What are you trying to do btw?

Itoo 2.1

Some of the features have been removed (such as actions) to reduce complexity .

  • Added Boot Receiver Block
    The functionality has been reintroduced.


  • Internal Changes to fully support changing Foreground notification through Notification Style Component (the new modified version)

  • Added methods to store values



    They are like Tiny DBs of Itoo, these blocks can be used in the background services, especially for non-foreground services to store and fetch properties. They provide special connectivity between services and and the application realtime.

  • Fixed internal issues, updated itoo-x framework.

(I'll update the first post later)

I'll be posting new guides later.


Yes, if i close app, they do not popup, if i open it, i have popup when i change data. I think if app is open, orange block "when FirebaseDB1.DataChanged" is working but if i close app i need use loop "changed" but they do not turn on.

How to change Itoo 2 extension notification icon?
There are no opition to change icon on block components, Then how to connect "NotificationsStyle" to Itoo Foreground notification service to use own icon?

Any simple block?

Are you by any chance try to replicate the same with web components or an API? Firebase components may be not supported right now.

You have to use the Modified Notification X.


It is actually done this way, you have to get the icon code from Android docs, you have to copy the Constant value number and set it in the extension.

To connect Notification Style, you would have to modify the notification Id's in the notification style extension code, i had just did that for music-notification.
