Key Terms

Server Client ID: this is the ID that Google provides in the Google Developer Console on the web.

    Welcome back.

  • 0:05

    Our app displays listings from Etsy and

  • 0:08

    successfully detects when Google Play services are available.

  • 0:12

    Now let's finish this app by integrating with the Google Plus APIs.

  • 0:17

    We're going to add in the +1 button so

  • 0:19

    users can promote content to their followers.

  • 0:22

    After that, we'll provide sharing directly to Google Plus.

  • 0:24

    Let's do this.

  • 0:26

    The first thing we want to do is request access to

  • 0:30

    the Google Plus APIs that are part of Google Play services.

  • 0:34

    To do this, we need to add an API and

  • 0:36

    any API options to the Google API client object.

  • 0:41

    We do this by calling add API to our Google API client builder object

  • 0:46

    in our Google services helper class.

  • 0:48

    Let's go ahead and add an API.

  • 0:52

    And we can see here that we simply need to add an API object.

  • 0:57

    As part of the Google Play Services Plus library there's a Plus.API object.

  • 1:02

    That's the API object we need.

  • 1:03

    And we're going to add in the Plus options as well, and the Plus

  • 1:07

    options are where we're going to actually set our unique identifier for our app.

  • 1:12

    Now we got this from the Google developer console,

  • 1:15

    the website that we registered with before we started everything.

  • 1:18

    So let's go over there right now, and we're going to need, under credentials

  • 1:22

    when we created our client ID we're going to need the client ID right here.

  • 1:26

    And it's this whole thing, so we're just going to go ahead and copy it.

  • 1:29

    So it's copied, and then we're going to use that back in our project here.

  • 1:33

    And what we need to do is use the Plus.Plus options.

  • 1:37

    And it has a builder as well, and with this builder there's a method called

  • 1:42

    setServerClientId, and you just pass it in as a string.

  • 1:45

    So we just copy it in here, the whole thing.

  • 1:48

    And we're going to call build on this, and

  • 1:52

    let's make sure we enclose this with a bracket here, and

  • 1:55

    we need to make sure that we got all of our parentheses lined up.

  • 1:59

    And it looks good now.

  • 2:00

    And that's all we need to do.

  • 2:01

    Now we have the API added along with our ServerClientId.

  • 2:06

    And now we'll be able to connect to the API client, connect to Google Play service

  • 2:11

    and be able to display our Plus One and Share buttons.
