    Welcome back. 0:04
    Our app displays listings from Etsy and 0:05
    successfully detects when Google Play services are available. 0:08
    Now let's finish this app by integrating with the Google Plus APIs. 0:12
    We're going to add in the +1 button so 0:17
    users can promote content to their followers. 0:19
    After that, we'll provide sharing directly to Google Plus. 0:22
    Let's do this. 0:24
    The first thing we want to do is request access to 0:26
    the Google Plus APIs that are part of Google Play services. 0:30
    To do this, we need to add an API and 0:34
    any API options to the Google API client object. 0:36
    We do this by calling add API to our Google API client builder object 0:41
    in our Google services helper class. 0:46
    Let's go ahead and add an API. 0:48
    And we can see here that we simply need to add an API object. 0:52
    As part of the Google Play Services Plus library there's a Plus.API object. 0:57
    That's the API object we need. 1:02
    And we're going to add in the Plus options as well, and the Plus 1:03
    options are where we're going to actually set our unique identifier for our app. 1:07
    Now we got this from the Google developer console, 1:12
    the website that we registered with before we started everything. 1:15
    So let's go over there right now, and we're going to need, under credentials 1:18
    when we created our client ID we're going to need the client ID right here. 1:22
    And it's this whole thing, so we're just going to go ahead and copy it. 1:26
    So it's copied, and then we're going to use that back in our project here. 1:29
    And what we need to do is use the Plus.Plus options. 1:33
    And it has a builder as well, and with this builder there's a method called 1:37
    setServerClientId, and you just pass it in as a string. 1:42
    So we just copy it in here, the whole thing. 1:45
    And we're going to call build on this, and 1:48
    let's make sure we enclose this with a bracket here, and 1:52
    we need to make sure that we got all of our parentheses lined up. 1:55
    And it looks good now. 1:59
    And that's all we need to do. 2:00
    Now we have the API added along with our ServerClientId. 2:01
    And now we'll be able to connect to the API client, connect to Google Play service 2:06
    and be able to display our Plus One and Share buttons. 2:11
