Because it does not specify the name of a particular target component;
rather it declares a general action to perform, which allows a component
from another app to handle it.

It is not an implicit intent. Implicit intents are offered by the ImplicitIntent class.

Because the destination and the content are not specified at the creation of the Intent but rather are set afterwards.
