Apps Clean up downloaded data during Uninstalling

[dolgong]

Application stores some data on sd card. I'd like to delete this data when user uninstall my app. Is there anyway to clean up used data on SDCard during uninstallation?

Thanks in advance.

It's not possible as your app will never "know" when it's being uninstalled.

Best you can do is either store data internally in your app's "data" storage space, or offer some sort of "cleanup" button inside your app.
