👂 Notification Listener Extension [Open Source]

This is just for your information, you do not have to ask for that permission

Did you build the test project for your tests?
Which device are you using for your tests?

Starting with sdk33 it looks like I have to add post notifications permission... but meanwhile you can enable that manually in the settings of the app

Taifun

Thanks for the prompt reply.

Did you build the test project for your tests?

I initially did it from scratch using the image in the pdf and have just now downloaded and run the aia file, my original try did not have the filter in it. So the AIA file loads up compiles and runs but still does not see my Reolink notifications.

I tried changing the filter string to include Reolink,door, hoping that might trigger a hit but no luck.

Reolink notifications as seen on the cell phone are
Reolink 7.05am
Camera Alert
door bell has detected motion

Which device are you using for your tests? Samsung A20 Android 11

I had thought that the TaifunNotificationListener had access to the "Notifications" that are raised by the cell phone, Incoming calls, incoming Push notifications, etc, maybe I misunderstand???

My desire is to capture the Push notification from my Reolink NVR. Currently I can intercept them with a Automate for Android script but I wanted to use App Inventor rather than Automate.

Danke!

the filter is by package name, so you should add the package name of that app
let me suggest you to first try a test without filter to see if you then get a notification... this also to find out the package name... then do another test including filter

yes exactly
but you should filter correctly, else nothing will be shown

Taifun

Taifun, you said
let me suggest you to first try a test without filter to see if you then get a notification.

Well I did that and I got a list of notifications then had a text sent to the phone and triggered some reolink notifications and did a get again and neither the phone or reolink messages appeared
did a screen capture and copied some files and another get and got some more messages
still no notification for phone or reolink


I can see
keyboard
USB file transfer
Cable charging

Danke

I only see system notifications in your screenshot... what about other apps like WhatsApp etc?

How are you testing?

  1. Start the notification listener test app to start the service and move the app to the background
  2. Then receive some notifications
  3. Open the notification listener test app again and check what has been stored

I will also do some tests and add

Taifun

this permission is not required to run the service
the example app just works fine for me on Samsung Galaxy A54 running Android 13

  1. How did you set the package name filter? It looks like you are using the package name filter com.andoid.systemui...
    As test remove all filter to get all notifications. If you get that running, then filter for the package name you are interested in

Taifun

g'day,

I tried a couple of things

put the app into the background
sent some whats app messages to the phone
still got the same notifications plus another hundred or so as I had my phone on charge overnight

then changed the set TaifunNotificationListener PackageNamesFilter
build reinstall and run again

Removed the set statement completely - had no effect
put back the set statement changed the input to a sting " " - had no effect
changed the input to "test" - had no effect
put back the set statement changed the input back to txtbPackageNamesFilter Text "test" - had no effect

still only getting the android and com.android.systemmui messages

it is as if the PackageNamesFilter was set at the first succesful instance of running the program and it cannot be changed - why that would happen goodness only knows

I am very happy to continue to try and resolve this issue, but, it is not critical to what I am doing, I have an alternative method to get the notifications using Automate for IT, which sees the notification I am after and the sends a text to the phone which I then action with my MIT App Inventor app.

Danke

You can change the filter only before starting the service... while it is running to change the filter does not have any effect... you can click Check to see if the service is running

Uninstall your current version
Rebuild the test project as it is and install it
Open the app and remove all filters
Click Start, enable notification access for the app and click Allow
Close the app
Let some notifications come
Open the app and check what has been stored

Taifun

G'day,

Success

Apart form the program initially having a filter set which was blocking my messages I was focused on the Get button.

The Get button can create a huge great list of things and if the filter string is wrong then of course the messages your looking for don't appear in the list.

In my screwing around I sent a text message and it magically appeared on my phone whilst I wasn't looking as a single item, much head scratching later, I believe I now understand what is going on.

I can receive my push notifications from Reolink and will look at porting some of this app over to my alarm monitor app.

I added a few buttons to your app whilst I was testing
set filter - writes filter string to - TaifunNotificationListener PackageNamesFilter
get filter - gets TaifunNotificationListener PackageNamesFilter - writes it to results label
clearDB tag - its not needed - but I want to cleared the DB and make sure everything was new -
refresh - erases the results label

Thank you very much for your support !

Cheers

in the above the filter textbox had been erased and then [set] PackageNamesFilter = ""

Hello, @Taifun can you make the extension version 5 available? I downloaded AIX now, but it is version 4.

Hi, I tried that notificaton listner but didnt work so is there any help or updates?

even open its aia file on my app but didnt work as well

So why the notificatons from aia file attached not working with me?

so why dont see the notifications here when i press get and i gave it the permission?

From your last screenshot it looks like you are using the package name filter... which means, only notifications from my alarmmanager example app and the systemui will be displayed...

???
There is a notification and the system updates it continuously...
unknown
and in the example app you get all recently displayed notifications...
where exactly is the problem?

Taifun

am just creating my first app on mit app inventor and i wanna make notifications for it especially messages

The notification listener listens for notifications from other apps...

to create notifications immediately use 🔔 MelonNotification • Various styled notifications + Itoo

to create notifications at a given time in the future, use the alarmmanager extension
