1. Wearable Droids for human beings
2. ABOUT THE SPEAKER Android 2.1+ Android Developer @ Ennova @_tiwiz tiwiz @_tiwiz
3. WHAT CAN WE DO ON ANDROID WEAR? Adding Wearable features to notifications Creating Wearable apps Creating Custom UIs Sending and syncing data Creating Watch faces Detecting location Requesting permissions Using the speaker
4. THE WEAR PLAYLIST WORKING WITH NOTIFICATIONS CUSTOM STUFF SYNC ALL THE DATA! USING THE SPEAKER
5. WORKING WITH NOTIFICATIONS Big Views BigTextStyle bigStyle = new NotificationCompat.BigTextStyle(); bigStyle.bigText(eventDescription); new NotificationCompat.Builder(this) NotificationCompat.Builder notificationBuilder = .setStyle(bigStyle);
6. WORKING WITH NOTIFICATIONS Wear specific actions BigTextStyle bigStyle = new NotificationCompat.BigTextStyle(); bigStyle.bigText(eventDescription); new NotificationCompat.Builder(this) NotificationCompat.Builder notificationBuilder = .setStyle(bigStyle); .extend(new WearableExtender().addAction(action)) // Big Views

9. CUSTOM STUFF Custom notifications Custom layouts Keeping your app visible
10. CUSTOM STUFF Custom notifications • Created on Wear • Not synchronised on the paired device
11. CUSTOM STUFF Custom notifications Custom layouts Keeping your app visible
12. CUSTOM STUFF Custom layouts • BoxInsetLayout • CardFragment • CircledImageView • ConfirmationActivity • CrossfadeActivity • DelayedConfirmationView • DismissOverlayView • GridViewPager • GridPagerAdapter • FragmentGridPagerAdapter • DotSpaceIndicator • WatchViewStub • WearableListView http://goo.gl/JYGOkO

16. THE WEAR PLAYLIST WORKING WITH NOTIFICATIONS CUSTOM STUFF SYNC ALL THE DATA! USING THE SPEAKER
17. SYNC ALL THE DATA! Access the data layer Choose the right way to communicate Implement the callbacks
18. SYNC ALL THE DATA! Declare Google API Client on both the phone and the wearable project Invoke connect() method Start using the client in the onConnected() callback Access the data layer
19. SYNC ALL THE DATA! Declare Google API Client on both the phone and the wearable project Invoke connect() method Start using the client in the onConnected() callback Access the data layer
20. SYNC ALL THE DATA! Access the data layer Choose the right way to communicate Implement the callbacks
21. SYNC ALL THE DATA! DataItem - automatic sync MessageApi - remote procedure calls Asset - blobs of data WearableListenerService - background services DataListener and MessageListener - foreground components ChannelApi - Assets sync’ed with DataItems, good for large files Choose the right way to communicate http://goo.gl/x8t3YG
