Ignore notification title ignored

[axxxxel]

I'm trying to forward the speed camera notifications of BLITZER.de to my AA screen. Everything works well but there is probably a problem with the "Ignore notification titles" setting.

BLITZER.de app has a persistent notification that changes icons when GPS signal state is changing. That happens pretty often in tunnels or under long bridges. These notifications always pop up with the title "Dummy - not used".
I thought to add this string to the titles blacklist but they are still popping up.

Is this "Dummy - not used" just set if the notification contains an empty string or something weird?
The persistent one one shows "App active" and some buttons.

Any recommendation how to remove these empty notifications?

Thanks man, great app!

Notifications in AA:

Can you please try with ignore group notifications enabled?

[ztNFny]

The string "Dummy - not used" is from this app - but it should never become exposed.
Can you please provide step by steps instructions (screenshots if required) on how to configure the app to trigger those notifications

All settings are pretty much unchanged.

• Blitzer.de app is selected
• No dismissed notifications
• Ignore titles can be anything
• Ignore group notifications tried both
• rest is unchanged

Maybe you can try it with the speed cam app installed by yourself? There is a free version available:

Could you share a screenshot of the Blitzer apps original notification please? Only way I see this happening is if both title and message are empty ...

With AA Notifications (3 changes during App startup)

I'm attaching a new apk with additional logging. Could you please enable debug logging in settings, then capture the log using "adb logcat" on a PC or any of the logcat apps on the PlayStore? The lines I'm looking for contain "xda.xlafbk.aanotificationforwarder"
app-release.apk.zip

[axxxxel]

Today I have no PC here to access my phone with abd or to grant access to logcat apps.
I will try tomorrow.

[axxxxel]

Now I have created a logcat.log file with grep "xlafbk" for the time starting up Blitzer.de and receiving the first 3 notifications

logcat.log

[ztNFny]

is that with the test-build I attached yesterday? I'm not seeing any of the new debug lines I added.

Edit: Actually I'm not seeing any debug lines. Did you enable the debugging setting in the apps settings?

[axxxxel]

Yes, that is your special version from yesterday and debugging is active (even though the check box is hidden behind the floating button...)
Maybe the logcat app is removing too much - this is the logcat without grep

logcat.log

[ztNFny]

Found it, sorry gave you the wrong advice on how to filter as my logcat output contains slightly different info.

It's as suspected: The notification has no content at all - very "interesting" app design there. I'll try to provide a fix later today.

Indeed, the app design is kind of wild.
This morning I took two more pictures

• the first how I like it to be (with speed camera detected)
• second picture is the app notification for an upcoming accident with "Dummy" string again...

[ztNFny]

It seems they not always have a description available. But I don't see any chance of treating the wanted and unwanted empty notifications differently, there's simply no info to differentiate them.
I could hardcode some special rules for that app, but those might easily break on app updates, so I don't really want to go that route.

BTW: If I understand it right those notifications are time-critical? You can't rely on Android Auto showing notifications in a timely manner. Their display is often delayed by many seconds, even minutes, after being sent by an app.

[axxxxel]

Is it maybe possible to check for the existence of a text content (2 min - 500m - A7)?
Otherwise I'm already happy to see the speed cam notifications.

I have recognised the delayed display already this morning. Every speed cam get's 3 alarms (500m, 150m, 50m).
The 500m warning comes in time but the later ones were delayed until I already passed the cam, but there is an alarm sound.

Is it maybe possible to check for the existence of a text content (2 min - 500m - A7)?

Can you get me a logcat of one of those? See above for what to look for

[axxxxel]

Will try - I just need to organize an accident for that...

[axxxxel]

On my way home I have recorded a speed cam notification with both title and body not null

logcat.log

[ztNFny]

new build attached, it shouldn't show those useless notifications anymore but hopefully still the accident one without title. If not a logcat for that one please.

Great, many thanks!
I will perform some trials and provide feedback.
Excellent support 👍

[axxxxel]

Everything fine now.
Thanks again - I have closed the issue.
