GDK: Give Hint in Voice Prompt

Is it possible to give the user "hints" using voice trigger's input prompt? This is would be similar to what the action "make a call" displays, giving you a list of possible options.

For instance using the following...

<trigger keyword="@string/start_scan" >

    <constraints
        camera="true"
        network="true" />

    <input prompt="@string/prompt_scan_what" />

</trigger>

I would like the user flow to be as follows...

------------
"Ok, Glass"
------------
"Scan"
------------
What would you like to scan?
QR Code
Product
Barcode
------------
"Barcode"

Have you tried adding a line feed character (i.e. '/n') after the question mark in the prompt text to get a fresh new line?

Found a workaround with a few cons:

  1. Bloats AndroidManifest depending on number of options.
  2. Different method of getting selected option.
  3. Can't be done programmatically.

  4. Workflow is more like...

    ---------
"Ok, Glass"
---------
"Scan"
---------
ok glass, scan...
QR Code
Product
Barcode
---------
"Barcode"

Android Manifest:

    <activity android:name="com.cantilsoftware.barcodeeye.LaunchActivity">
    </activity>

    <activity-alias
        android:name="Product"
        android:label="Product"
        android:targetActivity="com.cantilsoftware.barcodeeye.LaunchActivity" >
        <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_scan" />
    </activity-alias>
    <activity-alias
        android:name="Barcode"
        android:label="Barcode"
        android:targetActivity="com.cantilsoftware.barcodeeye.LaunchActivity" >
        <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_scan" />
    </activity-alias>
    <activity-alias
        android:name="QR Code"
        android:label="QR Code"
        android:targetActivity="com.cantilsoftware.barcodeeye.LaunchActivity" >
        <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_scan" />
    </activity-alias>

Selection detection:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_launch);

    try {
        ActivityInfo activityInfo = getPackageManager().getActivityInfo(getComponentName(), 0);
        processVoiceAction(activityInfo.loadLabel(getPackageManager()).toString());
    } catch (NameNotFoundException e) {
        e.printStackTrace();
        processVoiceAction(null);
    }
}
