This is not possible, unless you have another application installed on the phone.

ACTION_PACKAGE_REMOVED intent will be sent out to all receivers except for your own.

Broadcast Action: An existing application package has been removed from the device. The data contains the name of the package. The package that is being installed does not receive this Intent.
