Usage
You
typically don't need
to
worry
about managing apps beyond installing, opening, and using
them
.
But
there
may be
times
when you
want
to
know
more
about
what's
happening behind
the
scenes. Apps use
two
kinds
of
memory: internal storage and RAM. They use internal
storage
for
themselves and any files, settings, and
other
data
they
use. They also use RAM
(memory designed
for
temporary
storage and
fast
access) when they're running. Android
manages and carefully guards the portion
of
internal storage where
the
system, apps, and
most
data
for
those
apps
are
stored, because
this
area may contain your private informa-
tion. It's
not
possible
to
view
this
portion
of
internal storage when
you
connect your device
to
a
computer
with a USB cable. The
other
portion
of
internal storage, where music, down-
loaded files, and so on
are
stored, remains visible
for
your convenience. Android also
manages how apps use RAM. It may cache some things you've been using recently,
for
quicker access if
you
need
them
again,
but
it
will erase the cache if
it
needs
the
RAM
