How Can Change an Application icon programmaticall

问题:

I want to change an application icon directly from the program and don't want to create shortcut and update it. Some calender app changes icon everyday without creating shortcut. I read that can create activity-alias element for each of my icons in manifest. It's work for me but if I want to have 30 icons like a calender then I should have 30 activity-alias element in manifest and I do't think it's a correct way. I also read that this way works differently across devices. Can anyone help me?

You can do this in smart launcher.

there is an option in smart launcher to change icon of an app without creation a shortcut. if you are okay with the smart launcher then this is the way. I don't know any other way to do that.
