  <li>Copy the signed wearable app into your handheld project's <code>assets/</code> directory,

  referred to as <code>path/to/wearable_app.apk</code>.</li>

  <li>Copy the signed wearable app to your handheld project's <code>res/raw</code> directory. We'll

  refer to the APK as <code>wearable_app.apk</code>.</li>

  <li>Create a <code>res/xml/wearable_app_desc.xml</code> file that contains the version and

  path information of the wearable app:

<pre>

<wearableApp package="com.google.android.wearable.myapp">

  <versionCode>1</versionCode>

  <versionName>1.0</versionName>

  <path>path/to/wearable_app.apk</path>

  <versionCode>1</versionCode>

  <versionName>1.0</versionName>

  &lt;rawPathResId>wearable_app&lt;/rawPathResId&gt; <!-- Do not include the .apk extension -->

</wearableApp>

</pre>

<p>

The <code>package</code>, <code>versionCode</code>, and <code>versionName</code> are the

same as values specified in the wearable app's <code>AndroidManifest.xml</code> file. 

The path is the full path of <code>wearable_app.apk</code>, relative to the <code>assets/</code>

directory.

same values specified in the wearable app's <code>AndroidManifest.xml</code> file. 

The <code>rawPathResId</code> is the static variable name of the APK resource. For example, 

for <code>wearable_app.apk</code>, the static variable name is <code>wearable_app</code>.
