Android : Get coordinates of app icon in view pager of main screen/home screen programatically?

I want to animate the app icon on start of the app but how can i get exact position of icon on home screen/main screen but i don't know whether its possible or not.I know for widget its possible by getIntent().getSourceBounds() but for app icon, i didn't find anything.Is there any default api available to get this information and if yes will it work on any device which is custom like HTC sense or samsung?

I have searched about it a lot but didn't get any useful information.Ifanyone has any idea about this please let me know? Thanks in advance.
