+          Automatic syncing
+        </h4>
+
+        <p>
+          The Google Drive Android API uses the local device storage to create,
+          edit, and open files, then syncs them automatically when the device
+          is connected to the Internet. If a user requests a file that isn’t
+          already cached on the device, the Drive service downloads the file
+          the next time the device connects.<br>
+          <a href="http://developers.google.com/drive/android/files" class=

+
+        <h4>
+          User interface components
+        </h4>
+
+        <p>
+          Building your own user interface for selecting or creating files is a
+          thing of the past. The Drive API includes activity builders for two
+          of the most common user activities: opening files and creating
+          files.<br>
+          <a href="http://developers.google.com/drive/android/create-file"
+          class="external-link">Create a file</a>

+
+        <h4>
+          Easily search for files
+        </h4>
+
+        <p>
+          The query builder allows you to easily construct a query by joining
+          together multiple parameters and filtering based on metadata. This
+          allows you to easily display only relevant files, such as files
+          shared with the user or files with a specific MIME type.<br>

+          2. Run the sample
+        </h4>
+
+        <p>
+          Once you’ve set up the Google Play services SDK, you can run the

+          <code>&lt;android-sdk&gt;/extras/google-play-services/samples/drive</code>.
+          However, before you can run the sample, you need to register your app
+          in the Google Developers Console.

+        <p class="caution">
+          The Google Drive Android API is currently in <strong>developer
+          preview</strong>. Applications compiled using this version of the API will
+          continue to operate on devices using future versions of Google Play services;
+          however, changes to the API are expected in future releases.
