I'm pretty sure he's referring to the so-named Android building block,
which is approximately the same as a "message" in message-passing
systems. You might find the class doc at
useful. Brief excerpt:
An intent is an abstract description of an operation to
be performed. [...] An Intent provides a facility for
performing late runtime binding between the code in
different applications. Its most significant use is in the
launching of activities, where it can be thought of as
the glue between activities. It is basically a passive
data structure holding an abstract description of an
action to be performed.
