No dear you cant check that your application is going to uninstall.
When the user uninstalls the app, at first the process is killed, then your apk file and data directory are deleted, along with the records in Package Manager that tell other apps which intent filters you've registered for.
But you can create your folder in your cache dir so that when your application will be deleted all folders and files automatically will be deleted.
Please check it. http://developer.android.com/guide/topics/data/data-storage.html
So 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 uninstall.
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.
