Android Example App Icon Change at Runtime

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

https://www.b4x.com/android/forum/threads/change-icon-at-runtime.104009/

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.
  1. Don't forget to check the manifest.​

  2. Java code online in Main​

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

Hi mcqueccu
Please test my code. I don't find my problem what it is.
1. You did not add the ChangeIcon method

B4X:

FIX: ADD THIS TO THE MAIN MODULE

B4X:

public void changeIcon(String name){
    PackageManager pm = getPackageManager();
    pm.setComponentEnabledSetting( getComponentName(),PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
    pm.setComponentEnabledSetting(new ComponentName(this, name), PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);
    //restart(pm);
}
#End if

    pm.setComponentEnabledSetting(new ComponentName(this, name), PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);
    //restart(pm);
}
#End if
I think I don't be noticed. Because it is grey color. It should be blue color or others.

    //restart(pm);
}
#End if

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
