Since it has been asked on some occasions about how to change the icon, I decided to find out.

Of course @Erel gives his opinion on the matter here:
https://www.b4x.com/android/forum/threads/change-icon-at-runtime.104009/post-652119

In this thread @chjk has left his progress on this and I decided to use his example based on activity and convert it to B4XPages which I attach below. All credits to Him.

Don't forget to check the manifest.

The icon2.png file (read-only) in the folder ..\objects\res\drawable

1. You did not add the ChangeIcon method

I think I don't be noticed. Because it is grey color. It should be blue color or others.

Is there way to add this module not in main,but in bas file of module,and then compile to be library for B4A?

@Mariano Ismael Castro can you implement this for Adaptive Icons

I would like to help with this but I can't use B4i, I don't have an Apple developer account to create the certificate for my iPhone. Additionally, I don't have much experience with Objective C but maybe I can get it right away.

I mean for Android Adaptive Icons. Most apps do not use single Icon but basically 3 types or more consisting of transparent, foreground and background image. Check this post on adaptive icons. So am asking if this library can use the adaptive icon instead

Adaptive Icons - simple instructions and tips

All apps should have an adaptive icon. If you are not familiar with these icons then start here: Adaptive Icons Instruction steps: Create a new folder in the root project folder named icon. Create two folders inside that folder with the following files: mipmap: ic_launcher.png -...

I hadn't understood your question. I'll take a look to see if it can be implemented.

Olaan · Dec 4, 2023

In my openion,
Why Erel don't create #IconApp in #project attribute of B4A,B4J,B4i?
