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
<http://developer.android.com/reference/android/content/Intent.html>
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.
