Addo · Apr 7, 2018

i am trying to create a notifcation when service started i am using b4a version 8 and i have follow the instruction to set info at last call like following

B4X:

Sub Service_Create
    'This is the program entry point.
    'This is a good place to load resources that are not specific to a single activity.

    
    nNotify.Initialize
    nNotify.Icon = "icon"
    nNotify.Sound=False
    nNotify.Vibrate=False
    nNotify.Light=False
    nNotify.OnGoingEvent=True
    nNotify.SetInfo("back to app", "Test", Main2)
    Service.StartForeground(1, nNotify)
   

End Sub

but this crash on android 5.1 each time service started

thats how i start the service on main2 activity create

B4X:

StartService(Service)

You should post the error message from the logs.

i am trying to track the exception on the client side because its not running under the ide to track the log but it gives app stop from working i will try to catch the exception and post it

i have tried to catch the last exception seems no exception raised at all this is the device that was tested on

http://skydevices.com/elite-photopro/

its only give the app stopped from working if i remove the notification all together the app works fine

There must be an error message in the logs when the app stops.

Addo · Apr 9, 2018

very weird i have tried but no toast message exception when the app stopped from working message

B4X:

    Try
    
    nNotify.Initialize
    nNotify.OnGoingEvent=True
    nNotify.Sound=False
    nNotify.Vibrate=False
    nNotify.Light=False
    nNotify.Icon = "icon"
    nNotify.SetInfo("Test", "test", Main)

    Service.StartForeground(9999898, nNotify)
    
    Catch
    ToastMessageShow(LastException, True)
    End Try

Also I notice if I comment out the icon the app works without crash

B4X:

Try
    
    nNotify.Initialize
    nNotify.OnGoingEvent=True
    nNotify.Sound=False
    nNotify.Vibrate=False
    nNotify.Light=False
    'nNotify.Icon = "icon"
    nNotify.SetInfo("Test", "test", Main)

    Service.StartForeground(9999898, nNotify)
    
    Catch
    ToastMessageShow(LastException, True)
    End Try

What could be the problem with icon is it need to be under setinfo ?

Why aren't you checking the logs? Remove the Try / Catch block and let it crash with the full error message.

Addo · Apr 10, 2018

This device is not in my hand its a device of a client off mine its not running under the ide

You can add firebase crashlytics library, let the app crash at the customers device and check the Crashlytics crashreport in the Firebaseconsole later.

i will wait 24 hours until my firebase start capture also i notice on some old phones the icon of notifcation is not visible and have blue circle instead the sie of the icon is 36 its not that big also i have created drawable Resolution to capture the icon based on the phone Resolution

i have created

drawable-hdpi
drawable-ldpi
drawable-mdpi
drawable-xhdpi
drawable-xxhdpi

and make them read only to make it android friendly but the blue circle in older device is weird

Addo · Apr 11, 2018

i have added the firebase and test the exception logger with invalid int and receive the logger exception

but for the icon issue sadly it does not send any exception

only i got

Unfortunately System UI has stopped

when ever the icon called in notification and no exception sent

Erel · Apr 12, 2018

Sounds like a problem with the icon file itself. Remove all the resources you added and add a single one under drawable. Make sure that that icon is small.

Addo · Apr 12, 2018

Hi @Erel the current icon is 36x36 / 32 dipth should I make it smaller ? Like 16 x 16 I will give a try and give a feedback

Erel · Apr 12, 2018

It is not too large. Try it with a different icon.

Addo · Apr 12, 2018

i have tried with different icon from

https://romannurik.github.io/Androi...rim=1&source.space.pad=0&name=ic_stat_ac_unit

but sadly it does have the same behavior on LOLLIPOP

in LOLLIPOP 5.1 it gives

Unfortunately System UI has stopped

on LOLLIPOP 5.1.1 the icon is not visible there is blue circle instead

here is the test project attached

also here is an image attached from LOLLIPOP 5.1.1

I have read on google similar issues I came up with this but this is oreo certain not sure if its similar case for android 5 devices

https://stackoverflow.com/questions/47368187/android-oreo-notification-crashes-system-ui

Honestly did not find any work around for this issue only I had to detect the running api and not load the notification for the api that got this notification crash problem

Hope experts who stuck with similar issue to help with a better solution if there any solution for it

This is expected as the built-in Notification object doesn't set the large icon. Use barx's NotificaitonBuilder to create the notification.

Addo · Apr 13, 2018

What is the suggested size for the built-in notification icon 16x16 ?
