Glass XE17.1 - Custom voice commands broken? - google-glass

Question

I have followed the exact steps from the official documentation, but I still cannot get my app to start using the custom voice command. The steps are followed are:
1 Add new string resource for custom voice command in strings.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">Hello World!</string>
<string name="glass_voice_trigger">start example</string>
</resources>
2 Create a new XML file for voice startup definition:
<?xml version="1.0" encoding="utf-8"?>
<trigger keyword="#string/glass_voice_trigger" />
3 Request proper permissions in AndroidManifest.xml:
<uses-permission android:name="com.google.android.glass.permission.DEVELOPMENT" />
4 The manifest part looks as follows:
<service
android:name="pl.infoshare.sample.helloworld.HelloWorldService"
android:icon="#drawable/ic_lap"
android:label="#string/app_name"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="com.google.android.glass.action.VOICE_TRIGGER" />
</intent-filter>
<meta-data
android:name="com.google.android.glass.VoiceTrigger"
android:resource="#xml/voice_trigger_start" />
</service>
Still, I am not able to start the app using the voice command. If I change to one of the predefined voice commands the app shows up on the timeline and I can start it using the voice command. Did I miss anything?

Answer 1

Looking through the question, I didn't see anything jump out at me as incorrect. So, I created a small sample GDK project that is launched with a custom voice command, and runs just fine on my XE17.1 device. (Bonus, it demos a low-frequency LiveCard!)
Try pulling down my sample from GitHub, and see if you can launch it with the command:
'OK Glass, start my awesome app'
Below are some of the relevant bits.
AndroidManifest.xml:
<uses-permission android:name="com.google.android.glass.permission.DEVELOPMENT" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#android:style/Theme.DeviceDefault">
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:immersive="true">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<service
android:name=".LowFreqLiveCardService"
android:enabled="true"
android:exported="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name">
<intent-filter>
<action android:name=
"com.google.android.glass.action.VOICE_TRIGGER"/>
</intent-filter>
<meta-data android:name="com.google.android.glass.VoiceTrigger"
android:resource="#xml/voice_trigger"/>
</service>
</application>
</manifest>
res/xml/voice_trigger.xml:
<?xml version="1.0" encoding="utf-8"?>
<trigger keyword="#string/custom_keyword" />
res/values/strings.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">Low Freq Demo</string>
<string name="heart_rate">Heart Rate</string>
<string name="custom_keyword">start my awesome app</string>
</resources>
Here's a link to the voice command documentation, it still provides instructions on using custom voice commands. And, from my testing, they still do work.

Answer 2

Custom voice commands require, since a couple of versions ago, the aproval from google. You can send a request for that aproval from the glass developer site.
Review this.
