  You can use the

  <a href="{@docRoot}reference/com/google/android/gms/wearable/ChannelApi.html"><code>ChannelApi</code></a>

  class to transfer large data items, such as music and movie files, from a handheld to a wearable

  device. The Channel API for data transfer has the following benefits:

  <ul>

    <li>Transfer large data files between two or more connected devices, without

    the automatic synchronization provided when using

    <a href="{@docRoot}reference/com/google/android/gms/wearable/Asset.html"><code>Asset</code></a>

    objects attached to

    <a href="{@docRoot}reference/com/google/android/gms/wearable/DataItem.html"><code>DataItem</code></a>

    objects. The Channel API saves disk space unlike the

    <a href="{@docRoot}reference/com/google/android/gms/wearable/DataApi.html"><code>DataApi</code></a>

    class, which creates a copy of the assets on the local device before synchronizing with

    connected devices.</li>

    <li>Reliably send a file that is too large in size to send using the

    <a href="{@docRoot}reference/com/google/android/gms/wearable/MessageApi.html"><code>MessageApi</code></a>

    class.</li>

    <li>Transfer streamed data, such as music pulled from a network server or voice

    data from the microphone.</li>

  </ul>
