How add my application content with description and preview to Google search results? : <p>I found this article: <a href="https://search.googleblog.com/2016/08/a-new-way-to-search-for-content-in-your.html" rel="nofollow noreferrer">A new way to search for content in your apps</a> and I'm really excited for this opportunity. I want to show my application content in google search results, like this:</p>

<p><a href="https://i.stack.imgur.com/ZVsJU.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ZVsJU.gif" alt="Google In Apps Search"></a></p>

<p>But this article doesn't have any information about how to implement this features in your app.</p>

<p>I use <strong>App Indexing API</strong> in my application, as described in articles:</p>

<ul>
<li><a href="https://firebase.google.com/docs/app-indexing/android/activity" rel="nofollow noreferrer">Add the App Indexing
API</a></li>
<li><a href="https://developer.android.com/studio/write/app-link-indexing.html" rel="nofollow noreferrer">Add URL and App Indexing
Support</a></li>
</ul>

<p>This is my code:</p>

<pre><code>...
  private GoogleApiClient mClient;

  @Override protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.ac_main);
    mClient = new GoogleApiClient.Builder(this).addApi(AppIndex.API).build();
  }

  public Action getAction() {
    Thing object = new Thing.Builder()
        .setName("Test Content")
        .setDescription("Test Description")
        .setUrl(Uri.parse("myapp://com.example/"))
        .build();

    return new Action.Builder(Action.TYPE_VIEW).setObject(object)
        .setActionStatus(Action.STATUS_TYPE_COMPLETED)
        .build();
  }

  @Override
  public void onStart() {
    super.onStart();
    mClient.connect();
    AppIndex.AppIndexApi.start(mClient, getAction());
  }

  @Override
  public void onStop() {
    AppIndex.AppIndexApi.end(mClient, getAction());
    mClient.disconnect();
    super.onStop();
  }
...
</code></pre>

<p>And this is result:</p>

<p>Google show my application's <em>Test Content</em> but without description and preview image. <strong>Is there any ways to add description and preview image in Google Search Results?</strong> (like Youtube or Twitter)</p>
