Is there any way to change the small icon image (default used application icon) in the notification in the Android application with Delphi?
The standard way to easily create a notification is:
var
aNotification: TNotification;
begin
aNotification:= aNotificationCenter.CreateNotification;
try
aNotification.Name:= 'Notification Name';
aNotification.Title:= 'Notification Title';
aNotification.AlertBody:= 'Notification Alert Body';
aNotification.EnableSound:= False;
aWorkNotification.Number:= 1;
aNotificationCenter.PresentNotification(aNotification);
finally
aNotification.Free;
end;
end;
I know solution for Java, but I don't know how the same programmed in Delphi.
Advise me someone?

First, prepare the icon in png format (16 x 16, named for example ic_test). Save the png icon using the Deployment to these directories:
res\drawable-ldpi\
res\drawable-mdpi\
res\drawable-hdpi\
res\drawable-xhdpi\
res\drawable-xxhdpi\
Then use the following code:
.
.
var
Ntf: JNotification;
ntfBuilder: JNotificationCompat_Builder;
ntfManager: JNotificationManager;
.
.
ntfBuilder:= TJNotificationCompat_Builder.JavaClass.init(TAndroidHelper.Context);
ntfBuilder.setSmallIcon(TAndroidHelper.Context.getResources.getIdentifier(StringToJString('ic_test'), StringToJString('drawable'), TAndroidHelper.Context.getPackageName));
ntfBuilder.setContentTitle(StrToJCharSequence('Content Title'));
ntfBuilder.setContentText(StrToJCharSequence('Content Test'));
ntfBuilder.setAutoCancel(True);
Ntf:= ntfBuilder.build;
ntfManager:= TJNotificationManager.Wrap((TAndroidHelper.Context.getSystemService(TJContext.JavaClass.NOTIFICATION_SERVICE) as ILocalObject).GetObjectID);
ntfManager.notify(1, Ntf);
.
.
If you want to use built-in system icons use this constants
