I compiled and ran AppNotificationManagerDemo1, unfortunately, my
attempt failed under android13, the program crashed after clicking the
Push System Notification button, but my phone using android4.1 also
ran successfully, what is the reason, how do I need to troubleshoot
and solve the problem?

[using the translator]

From what I've noticed, it doesn't work on new phones because of the
appcompat theme.

on old smartphones, it works with the default theme (deviceDefault)

I believe the NotificationManager component is not updated to use
appCompat

The component is working perfectly, there is something in the Demo
that is bad, but as it is a Demo, it is better not to use it

do it like this

Create a new project, add only the NotificationManager1 component to
the form

create a button and place the code in the button's onClick

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.Button1Click(Sender: TObject);begin 
 NotificationManager1.Notify();end;
try it



It's better to use the Demos just to see the codes

As the Lamw project changed over time, the Demos didn't keep up, but
over time everything got better.

Thanks for the reply, I created a new project, put a button and a
jNotificationManager control on it, wrote the code in the click event
of the button NotificationManager1.Notify(); No error is reported when
the execution is executed, but the Notify message does not appear.

In addition, I found that the crash in the demo problem was not caused
by jNotificationManager, but by jIntentManager, which was caused by
jNotificationManager1.SetContentIntent(......) Comment out, demo does
not report error under android13, but again, the notify notification
message does not appear after the code is executed.

Hi,
It related to missing required flag for PendingIntent.

EXCEPTION MSG:
Quotecalled with pending exception java.lang.IllegalArgumentException:
com.example.appnotificationmanagerdemo1: Targeting S+ (version 31 and
above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be
specified when creating a PendingIntent.
Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some
functionality depends on the PendingIntent being mutable,
e.g. if it needs to be used with inline replies or bubbles.
GAIN NOTIFICATIONS PERMISSION:
1- manifest side:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i <uses-
permission android:name="android.permission.POST_NOTIFICATIONS"/>
2- use runtime permission call to ask user.

Thank you very much for your guidance, I now use AndroidStudio to open
the project after modification, and use AndroidStudio to compile and
install can pop up the notify prompt window!

In addition, I experimented with it, as long as I added <uses-
permission android:name="android.permission.POST_NOTIFICATIONS"/>
permission, the notify pop-up window was also correctly popped up when
I compiled and ran it directly in Lazarus, and I didn't need to open
AndroidStudio to adjust jNotificationManager.java code, thanks again
to everyone for their help!
