Android application icon changes with runtime

In my app I want to display different icons for the application. Changes should be according to the scenario. For example, it will mark the numbe开发者_开发知识库r of days remaining for the task completion. On the android menu this icon will display the number of days remaining. If anyone has any idea for this, I would appreciate it. Thanks.
