- 1. Ok Glass… Make me a sandwich Luis González Android Team Leader luis.gonzalez@intelygenz.com
- 5. No te metas en medio
- 6. ¿Cómo puedes hacer esto? Android + Glass Development Kit
- 8. Instalar GDK
- 9. Componentes GDK 1. Timeline 2. Live Card 3. Static Card 4. Immersion 5. Menús(*) 6. CardScroll: Adapter + View 7. Voice Trigger
- 10. GDK: TimelinePresente y futuro Pasado
- 11. GDK: Static Card // Create with current context Card mCard = new Card(mContext); mCard.setText("Esto es una static card"); mCard.setFootnote("Y esto es su footer!"); // Add card to timeline TimelineManager.from(mContext).insert(mCard);
- 12. GDK: Live Card
- 13. GDK: Live Card // Create livecard using TimelineManager mLiveCard = TimelineManager.from(mContext).createLiveCard(LIVE_CARD_SAMPLE_1_TAG); // Set and save live card remote view to modify it later mLiveCardRemoveViews = new RemoteViews(getPackageName(), R.layout.livecard1); mLiveCard.setViews(mLiveCardRemoveViews); // Publish livecard in REVEAL mode (alternative to SILENT mode) // Set a PendingIntent to handle livecard actions (like a menu) Intent intent = new Intent(mContext, MenuActivity.class); mLiveCard.setAction(PendingIntent.getActivity(mContext, 0, intent, 0)); mLiveCard.publish(LiveCard.PublishMode.REVEAL);
- 14. GDK: Immersion
- 15. GDK: Immersion public class GlassSampleImmersion extends Activity { protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.immersion); } public boolean onCreateOptionsMenu(Menu menu) { // Inflate menu as usual MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.sample3menu, menu); return true; } public boolean onKeyDown(int keyCode, KeyEvent event) { // Capture tap to display menu if (keyCode == KeyEvent. KEYCODE_DPAD_CENTER) { openOptionsMenu(); return true; } return false; } }
- 16. GDK: Menús
- 17. GDK: CardScroll ListView ArrayAdapter CardScrollView CardScrollAdapter
- 18. GDK: CardScroll protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Create array of sample cards to use in the adapter createCards(); // Create view programmatically mCardScrollView = new CardScrollView(mContext); CardScrollAdapter adapter = new MyCardAdapter(); mCardScrollView.setAdapter(adapter); // Important! Views are NOT active by default mCardScrollView.activate(); // Set activity view as usual setContentView(mCardScrollView); } private class MyCardAdapter extends CardScrollAdapter { (...) public View getView(int position, View convertView, ViewGroup parent) { // Cards are able to render themselves return mCards.get(position).toView(); } }
- 19. GDK: Voice Trigger ok glass, get directions to… send a message to… make a call to… play music... ok glass, play music… which artist? Voice Trigger Voice Trigger Prompt
- 20. GDK: Voice Trigger <?xml version="1.0" encoding="utf-8"?> <resources> <string name="glass_voice_trigger">play music</string> </resources> 1) res/values/strings.xml <?xml version="1.0" encoding="utf-8"?> <trigger keyword="@string/glass_voice_trigger" /> 2) res/xml/myTrigger.xml <activity | service ...> <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/myTrigger" /> </activity | service> 3) AndroidManifest.xml
