How do I use MIT app inventor's background task extension which helps the app to run in background?

Okay, so here is how you need to do it:

  • First set all the Airtable credentials through the property blocks, the sheet name, API key etc.

  • Then, suppose you want to use the GotCell block. First you need to register the event "GotCell" through the RegisterEvent block, like "AirtableClassic1.GotCell", and supply a function name, the function provided will have the same arguments as the event.

  • Then you would normally call the "GotCell" block, and it would trigger the corresponding procedure registered after getting the data of the cell.

Can this code get message in background and show it on the label.

22

Unfortunately, I dont not know the extension you are using.
The next step you have to do is to create a procedure which the numbers of arguments the "GotCell" has.

Here is the example of the Timer event in clock.

Please post your blocks, what have you tried so far?

Actually I was trying to get message and store it in a variable and when the app will open then the message will be shown on the label
But it didn't worked!

33

I do not know about Firebase API, why dont you try out yourself, just replace the URL with your firebase API call.

34

let me try

35

I get an firebase extension in which firebase url and api can be changed from the blocks also.

37

Please try that yourself, I cannot help you with complete blocks

Ok, thank you for your help and also for the extension but can you tell me the latest version of itoo or background task extension(which i should use).
