What is not working?

Simple notifications created by Itoo NOT opening the app when clicked.

[Kumaraswamy]

I'll check and let you know about that

I have gotta say, I am also running into the same issue I am wondering if there is a bug/regression with the last release of ltoo?

I am trying to replicate the notification example as well, and here are my observations:

• I am using the latest version (released on 10/22), and I don't have the "Notification" or "SimpleNotification" blocks that others seem to have.
• I made a test project and duplicated the notification example (except for the notification block in the timer function, since I don't have it showing up on mine). My button2 text never turned to "timer" meaning that creating the process never called the clock procedure.
• Similarly, my label2 text never became a random integer, because it was never called.

[Kumaraswamy]

Hi, thats because you cannot interact with the Visible component from Itoo.

[aeozyalcin]

I see what you are saying. I went ahead and added the notification extension, and using the simpleNotification now in an attempt to see some life out of the background process, but still no luck. Is there anything obviously wrong with the blocks?

[Kumaraswamy]

Post your project .aia here, so that I can look into it.

Attached, thank you!

This is just a test project I put together to try to learn how to use ltoo, and I am struggling with the basics here. My end goal on my other project is to try to use "RegisterEvent" block to listen for ble.bytesReveived events

[Kumaraswamy]

The project you sent me completely works fine

Check if you have enabled the Notifications permissions.

[aeozyalcin]

That did the trick, thank you so much! Not only did I have to enable notifications, but it also looks like this extension only works on compiled versions of the app. I couldn't get it to work with the MIT AI companion app.

So I am now moving on to see if I can get the process to get triggered on a BLE byte received event. I put this together based on other messages on this thread, but I am not getting any simple notifications to show me that my app is indeed receiving the BLE data. I know for sure that I am connected to the BLE device and that my device is definitely receiving data (confirmed with NRF connect app). Any pointers here?

[Kumaraswamy]

For that, you would need to move the entire BluetoothLE functionality over to Itoo, or the bleBackgroundReg procedure.

That means, move the ConnectWithAddress functionality, register an event for BluetoothLE's Connected event, and call RegisterForBytes from there. These three things should happen from the Itoo's background procedure (bleBackgroundReg) procedure

[aeozyalcin]

INCREDIBLE! Amazing work @Kumaraswamy thank you so much for the guidance.

Paying it forward by sharing what I have working here. I was able to offload BLE to a background process. Next step: figure out how to exchange data between background and foreground process.

That's amazing, here is a resource that could further help you:

Detailed guide for creating a music player with #Itoo

Music Player This guide showcases the use of #Itoo for creating a foreground music player application Blocks Summary [Blocks] Above is the summary of the project, the blocks inside the border are of the foreground service, i.e. they run independently (closing/reopening app would not have any affect on them) Explanation [Component 2(1)] We can categorize services into two types: background (invisible to the user) and foreground (user-visible). We've chosen to use a foreground servic…

It will give you more idea of how Itoo works and a few things about application to foreground/background process communication.

I'll check and let you know about that

I tried changing Simple Notification id's value, but still Simple notifications created by Itoo NOT opening the app when clicked.

Hello, I want try Itoo, I instaled Itoo extension ok

I view the images in the top
I can not found
Itoo1.CreateWithTrigger
Itoo1.Notification

Please where are the examples (I can not found examples on google)

Thank you

It looks like @Kumaraswamy should update the documentation in the first post...

Use the notification style extension together with itoo to send notifications

Extension: Modified Notification Style to support Android 12 and above

Modified version of Notification Style Extension By @Jarlissonlira2, adds support for Android >= 12 Refer to the original topic for documentation: Fork of the extension: github.com/XomaDev/NotificationStyleAIX License (MIT) and modified sources (rush): rush-compatible/notification-style [component_event(5)] [component_method(17)] [component_method(16)] New permission blocks for Android Tiramisu (for >= 33). android.permission.POST_NOTIFICATIONS Make sure to ask the permission if th…

Here are 2 examples in the first post

And read the complete itoo thread to find more examples...

This extension is an advanced extension... try the examples and play with the extension to get a better understanding how it works...

Hi
I'm trying to find a simple working example of a background task to understand how it's working but I can't find any. I read all the threads about that subject but they are all at least 1 y old and most of the blocks are deprecated.

Is there an updated version of the extension ? I feel that if things change so fast then even if I get something to work it might not a few months after.

I'm trying to make mqtt receiver work in the background and set an alarm if need. The alarm extension works fine when the app is in the foreground but need to be able to set it when the app runs in the background.

Thanks in advance

@Jimis

I read all the threads about that subject

You only have to read this thread from the beginning to the end to find several examples...

The latest version of an extension yoi always can find in the first post

Staet with something simple and get that working first and if you got stuck, show us a screenshot of your relevant blocks

Hi! I have the same issue with the following error message: No such service ComponentInfo{edu.mit.appinventor.aicompanion3/xyz.kumaraswamy.itoo.ItooJobService}

I tried using both the emulator and building the app and testing on my phone (in which case there is no message but nothing happens). My blocks are attached.

Essentially this just waits and checks if all data is received from tinywebdb before proceeding. I never received the message from the notifier implying the block is never executed, am I missing something or applying this incorrectly? For reference I had messages with similar notifiers in other blocks as well and the messages were displayed without any issue. Thanks!
