Below is original answer, I have since made a reference project that takes the Google documentation and updates it for XE16 using the StopWatch project as a reference. Check the code and commit history to learn a lot more:

One way is to declare a voice trigger to start the service/livecard.

This is mentioned in this pattern explanation:

The technique is described here:

I tested it out with your code and it worked if the manifest has these items (modify for your package name of course) ... this first one goes inside the application tag:

<serviceandroid:name="com.example.lowfrequencylivecardexample.LiveCardService"android:enabled="true"android:exported="true"android:label="@string/app_name" ><intent-filter><actionandroid:name="com.google.android.glass.action.VOICE_TRIGGER" /></intent-filter><meta-dataandroid:name="com.google.android.glass.VoiceTrigger"android:resource="@xml/voice_trigger" /></service>

You also need:

<uses-permissionandroid:name="com.google.android.glass.permission.DEVELOPMENT" />

You will also need this file ... res/xml/voice_trigger.xml:

<?xml version="1.0" encoding="utf-8"?><triggerkeyword="basketball" />

I found the Timer project to be helpful in coming up with this, here is its manifest:

Optionally you can make the home team the Celtics and the away team the Lakers. Larry Legend forever!
