title: How to start an Android Service via a URL Scheme?
body: <p>My Android app start with a Service. </p>
  
  <p>I am looking at URL schemes. While I had no problem setting this up (data  android:scheme="abc"), it appears calling "abc://" from the browser does not work, and I can't find anything in Logcat. </p>
  
  <pre><code>    &lt;service
          android:name="com.xyz.abcService"
          android:icon="@drawable/ic_launcher"
          android:label="@string/app_name"
          android:enabled="true"
          android:exported="true"&gt;
          &lt;intent-filter&gt;
              &lt;action android:name="com.google.android.glass.action.VOICE_TRIGGER" /&gt;
          &lt;/intent-filter&gt;
          &lt;meta-data
              android:name="com.google.android.glass.VoiceTrigger"
              android:resource="@xml/voice_trigger_start" /&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;category android:name="android.intent.category.LAUNCHER" /&gt;
                   &lt;data  android:scheme="abc" /&gt;
          &lt;/intent-filter&gt;  
      &lt;/service&gt;
  </code></pre>
  
  <p>Prior to adding an intent-filter to the Manifest file, it looked like: </p>
  
  <pre><code>    &lt;service
          android:name="com.xyz.abcService"
          android:icon="@drawable/ic_launcher"
          android:label="@string/app_name"
          android:enabled="true"
          android:exported="true"&gt;
          &lt;intent-filter&gt;
              &lt;action android:name="com.google.android.glass.action.VOICE_TRIGGER" /&gt;
          &lt;/intent-filter&gt;
          &lt;meta-data
              android:name="com.google.android.glass.VoiceTrigger"
              android:resource="@xml/voice_trigger_start" /&gt;
      &lt;/service&gt;
  </code></pre>
  
  <p>Even when removing the voice trigger, I could not launch abc. </p>
  
  <p>That being said, I had no issue when calling an Activity. </p>
  
  <p>Is anybody aware of any restriction around that? </p>
