I created an application which creates and stores files to sdcard. Is there a way to bind the folder with application in order to delete all files when the user runs uninstall on android device?
There's no way for your application to know that it is being uninstalled (without modifying the kernel). All files created in the data/data/your.app.package is deleted automatically upon application uninstall.
I don't think anything is cleared from the sdcard. You can do a quick test and find that out.
Another approach could be to have another application that checks whether this application is installed or not. If not, it can do the clean-up work.
