Is it possible to programmatically uninstall a package in Android

Question

Can a package uninstall itself? Can a package uninstall another package if they share the same userId and signature?

Answer 1

Third Party app cannot Uninstall App Silently!

Either you need to become System App to get DELETE_PACKAGES Permission else you need to show Uninstall Popup (User Confirmation)

Alternatively, you can take Accessibility permission and then by showing an Accessibility Overlay you can tell your service to click on Uninstall button! But that will be privacy violation.
