Google Chat-- so formerly, Hangouts,
now called Google Chat.
This is where this gets tricky.
Please read the notes of the book.
You could have two ways to install Google Chat.
One is embedded in the Gmail app,
which is off by default, or as a standalone application.
So you could go out to the Play Store and download this.
What we're going to get from it--
we can see timestamps, we could see group names, sender,
message, any attachments.
And these attachments are going to be stored in blobs.
Blobs are Binary Large Objects.
We are going to start focusing on blobs, how to parse them,
what the data looks like, and why
these applications use them.
They may seem annoying to you at first.
However, a blob is actually wonderful
because all that data is stored in some kind of format
right there in the database, and you
can extract it and examine it.
So think of Google Chat in its present form
is like Slack, where you can go back and forth with messages,
group members, calling, file transfers.
It's amazing, but there could be two locations
where that data is stored.
So please read the notes.
Please leverage your cheat sheet,
which has this on it, that will track where these files exist.
