Google Glass GDK Hello World Immersion Activity

Question

Steps, I have used to create my first Google Glass GDK App

New Project > Application name, company domain > Next > Glass (Glass Development Kit Preview (Google Inc.) (API 19)) > Next > Immersion Activity

ImmersionActivity.java:

public class ImmersionActivity extends Activity {

    /**
     * {@link CardScrollView} to use as the main content view.
     */
    private CardScrollView mCardScroller;

    private View mView;

    @Override
    protected void onCreate(Bundle bundle) {
        super.onCreate(bundle);

        mView = buildView();

        mCardScroller = new CardScrollView(this);
        mCardScroller.setAdapter(new CardScrollAdapter() {
            @Override
            public int getCount() {
                return 1;
            }

            @Override
            public Object getItem(int position) {
                return mView;
            }

            @Override
            public View getView(int position, View convertView, ViewGroup parent) {
                return mView;
            }

            @Override
            public int getPosition(Object item) {
                if (mView.equals(item)) {
                    return 0;
                }
                return AdapterView.INVALID_POSITION;
            }
        });
        // Handle the TAP event.
        mCardScroller.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                // Plays disallowed sound to indicate that TAP actions are not supported.
                AudioManager am = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
                am.playSoundEffect(Sounds.DISALLOWED);
            }
        });
        setContentView(mCardScroller);
    }

    @Override
    protected void onResume() {
        super.onResume();
        mCardScroller.activate();
    }

    @Override
    protected void onPause() {
        mCardScroller.deactivate();
        super.onPause();
    }

    /**
     * Builds a Glass styled "Hello World!" view using the {@link CardBuilder} class.
     */
    private View buildView() {
        CardBuilder card = new CardBuilder(this, CardBuilder.Layout.TEXT);

        card.setText(R.string.hello_world);
        return card.getView();
    }

}

Manifest.xml:

    <activity
        android:name=".ImmersionActivity"
        android:icon="@drawable/ic_glass_logo"
        android:label="@string/title_activity_immersion" >
        <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" />
    </activity>

voice_trigger.xml:

 <trigger command="SHOW_ME_A_DEMO" />

Now, what i have understood, we can run this app by trigger voice command "SHOW ME A DEMO", Is that right or wrong ?

And is there any way to run Glass GDK app on Android Emulator using Android Studio ?

It's correct. YOu can even configure this trigger and use other commands.

And is there any way to run Glass GDK app on Android Emulator using Android Studio ?

No you can't. Only Tablet, Phone, Wear (watches) and TV devices are available on the Android Virtual Device Manager.
