I want to use multiple launcher icon . what i want that user can change launcher icon with his selection
is it possible to change launcher icon run time?

Strictly speaking you can not change launcher icon at run time. However there are few workarounds available for this:
1. Activity alias:
Create multiple activity-alias tags in Manifest for your MAIN launcher activity and give a different icon drawable to it. You can then choose a particular activity-alias via your code as per your requirement.
2. Install/Uninstall Shortcuts: This approach won't change the your app's icon however you can update (read re-install) your app's shortcut-icon.
Hope this helps.
