Android Wear: from zero to hero

Android Wear è ormai una realtà abbastanza diffusa e poterlo utilizzare al meglio può senz’altro dare una marcia in più alle nostre app: vedremo in questo workshop come integrare l’SDK di Android Wear, partendo innanzitutto dalle regole per lo sviluppo con Android Wear e dal setup della nostra postazione di lavoro, passando poi alla gestione delle notifiche ricche, la comunicazione con il dispositivo indossabile e la creazione di una semplice app che metta a frutto le tecnologie che abbiamo appreso, cercando di sfruttare al massimo le potenzialità che Google ci ha fornito.

9. The Wear Playlist • Setting up the environment • Download the base project • Working with Notifications • Custom stuff • Sync all the data!
10. Working with Notifications Big Views BigTextStyle bigStyle = new NotificationCompat.BigTextStyle(); bigStyle.bigText(eventDescription); new NotificationCompat.Builder(this) NotificationCompat.Builder notificationBuilder = .setStyle(bigStyle); http://goo.gl/GLhd78
11. Working with Notifications Wear specific actions BigTextStyle bigStyle = new NotificationCompat.BigTextStyle(); bigStyle.bigText(eventDescription); new NotificationCompat.Builder(this) NotificationCompat.Builder notificationBuilder = .setStyle(bigStyle); http://goo.gl/GLhd78 .extend(new WearableExtender().addAction(action)) // Big Views
12. Working with Notifications ~ 30 minutes BigTextStyle bigStyle = new NotificationCompat.BigTextStyle(); bigStyle.bigText(eventDescription); new NotificationCompat.Builder(this) NotificationCompat.Builder notificationBuilder = .setStyle(bigStyle); http://goo.gl/GLhd78 .extend(new WearableExtender() .addAction(action)) // Big Views // Wear specific actions
13. The Wear Playlist • Setting up the environment • Download the base project • Working with Notifications • Custom stuff • Sync all the data!
14. Custom stuff • Custom notifications • Custom layouts • Keeping your app visible
15. Custom stuff Custom notifications • Created on Wear • Not synchronised on the paired device
16. Custom stuff • Custom notifications • Custom layouts • Keeping your app visible
17. Custom stuff Custom layouts • BoxInsetLayout • CardFragment • CircledImageView • ConfirmationActivity • CrossfadeActivity • DelayedConfirmationView • DismissOverlayView • GridViewPager • GridPagerAdapter • FragmentGridPagerAdapter • DotSpaceIndicator • WatchViewStub • WearableListView http://goo.gl/JYGOkO
18. Custom stuff • Custom notifications • Custom layouts • Keeping your app visible
19. • Extend WearableActivity • Call setAmbientEnabled() • Override onEnterAmbient(Bundle ambientDetails) • Override onExitAmbient() • Don’t forget onUpdateAmbient() Custom stuff Keeping your app visible http://goo.gl/D7oixw
20. Custom stuff • Custom notifications • Custom layouts • Keeping your app visible
21. Custom stuff goo.gl/D7oixw goo.gl/JYGOkO Code time! ~45 minutes
22. The Wear Playlist • Setting up the environment • Download the base project • Working with Notifications • Custom stuff • Sync all the data!
23. Sync all the data! • Access the data layer • Choose the right way to communicate • Implement the listener
24. 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 • Module /communication in the sample project Access the data layer
25. Sync all the data! • Access the data layer • Choose the right way to communicate • Implement the listener
26. 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
