Hello World For Google Glass

Question

I'm trying to build a simple Hello World GDK program for Google Glass. I've looked up everywhere, but all the samples I could find used "Timeline Manager", which was removed by Google after XE 16.

What I'm trying to do is to create a live card that shows texts (Hello world!) in the middle. I've tried to modify codes from HERE (HuskyHuskie's answer) and HERE (IsabelHM's answer)

However, no matter what I did, no option or voice command appeared on the glass even though the console showed that the program is installed on device.

What I mostly modified was take out the TimelineManager part and replace

mLiveCard = mTimelineManager.createLiveCard(LIVE_CARD_ID); with mLiveCard = new LiveCard(this,LIVE_CARD_ID);

Also, I'm relatively new to Android. I don't quite understand how R.id.XXXX and R.layout.XXXX are missing from the resource. Do you need to define it in Manifest or what else?

The following is the onStartCommand method:

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
            RemoteViews aRV = new RemoteViews(this.getPackageName(),
            R.layout.card_text);
    if (mLiveCard == null) {
       // mLiveCard = mTimelineManager.createLiveCard(LIVE_CARD_ID);
        mLiveCard = new LiveCard(this,LIVE_CARD_ID);

        aRV.setTextViewText(R.id.main_text, INTRO);
        mLiveCard.setViews(aRV);



        Intent mIntent = new Intent(this, MainActivity.class);
        mIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK |    Intent.FLAG_ACTIVITY_CLEAR_TASK);
        mLiveCard.setAction(PendingIntent.getActivity(this, 0, mIntent, 0));
        mLiveCard.publish(LiveCard.PublishMode.REVEAL);
    } 
    return START_STICKY;
}

Ok I got it to work following THIS

Note that the Manifest is not entirely correct. You need to add this line in the Manifest after the XE16 update:

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

See the post HERE for reference.
