Is it possible to self-delete the application with certain rights. When you install the rights will be issued. This is not a virus, it is not sold through Play.

Answer 1

This is possible without root access (hide the icon and work only in settings => running applications)

Deleting with a dialog call deletions can be implemented without root access. With root access, you can do pm uninstall without a dialog for the user
