title: Deep-linking intent does not work
body: <p>I followed the insttructions on <a href="https://developer.android.com/training/app-indexing/deep-linking.html">https://developer.android.com/training/app-indexing/deep-linking.html</a>, but when I want to trigger the intent through <code>adb</code> with:</p>
  
  <pre><code>adb shell am start
             -W -a android.intent.action.BROWSEABLE
             -d "http://example.com/gizmos" com.myapp.android
  </code></pre>
  
  <p>I just get </p>
  
  <blockquote>
    <p><code>Error: Activity not started, unable to resolve Intent {
    act=android.intent.action.VIEW dat=example://gizmos flg=0x10000000
    pkg=com.myapp.android }</code></p>
  </blockquote>
  
  <pre><code>&lt;activity
          android:name=".activities.DeepLinkActivity"
          android:label="@string/title_activity_deep_link"&gt;
          &lt;meta-data
              android:name="android.app.searchable"
              android:resource="@xml/searchable" /&gt;
  
          &lt;intent-filter&gt;
              &lt;action android:name="android.intent.action.VIEW" /&gt;
  
              &lt;category android:name="android.intent.category.DEFAULT" /&gt;
              &lt;category android:name="android.intent.category.BROWSABLE" /&gt;
  
              &lt;data
                  android:scheme="http"
                  android:host="example.com"
                  android:pathPrefix="/gizmos" /&gt;
          &lt;/intent-filter&gt;
      &lt;/activity&gt;
  </code></pre>
  
  <p>Have I made any obvious mistakes?</p>
