4. Notifications
5. Notifications Simplicity Context Extension
6. Actions
7. Actions NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) .setSmallIcon(R.drawable.ic_event) .setContentTitle(eventTitle) .setContentText(eventLocation) .setContentIntent(viewPendingIntent) .addAction(R.drawable.ic_map, “Map Title”, mapPendingIntent);
9. Notification stack NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) .setSmallIcon(R.drawable.ic_event) .setContentTitle(eventTitle) .setContentText(eventLocation) .setContentIntent(viewPendingIntent) .setGroup(“group_unique_name”)
10. NotificationCompat.WearableExtender
11. Notification NotificationCompat.WearableExtender wearableExtender = new NotificationCompat. WearableExtender() .setHintHideIcon(true) .setBackground(mBitmap); NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) .setSmallIcon(R.drawable.ic_event) .setContentTitle(eventTitle) .setContentText(eventLocation) .setContentIntent(viewPendingIntent) .extend(wearableExtender);
12. Background 400x400 px or 640x400 px
13. Drawables res/drawables-nodpi
14. Voice Actions
15. Standalone apps!
16. Standalone app • Offline mode • Custom UI • Access to sensors (and more) • Background work • ....
17. APK APK
18. Mobile Module ? Wear Module
19. Google Play Services
20. Data exchanging • DataItem API • Message API
21. Message API
22. DataItem API
23. Data Layer Interfaces interface DataListener { void onDataChanged(DataEventBuffer dataEvents); } interface MessageListener { void onMessageReceived(MessageEvent messageEvent); } interface NodeListener { void onPeerConnected(Node node); void onPeerDisconnected(Node node); }
24. Teleport github.com/Mariuxtheone/Teleport
25. Teleport TeleportClient mTeleportClient = new TeleportClient(this); mTeleportClient.connect(); mTeleportClient.sendMessage("startActivity", null); mTeleportClient.syncInt("myInt", 12345); setOnGetMessageTask(new TeleportService.OnGetMessageTask { @Override protected void onPostExecute(String path) { if (path.equals("startActivity")){ Intent startIntent = new Intent(this, WearActivity.class); startIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(startIntent); };}
26. EventBus
27. BusWear github.com/tajchert/BusWear
28. EventBus
29. EventBus
30. BusWear
31. EventBus.getDefault().post(parcelableObject, this); EventBus.getDefault().postRemote("text", this); EventBus.getDefault().postLocal(object); protected void onCreate(Bundle savedInstanceState) { EventBus.getDefault().register(this); } public void onEvent(ParcelableObject parcelableObject){ } public void onEvent(String text){ } BusWear
35. WearHttp github.com/takahirom/WearHttp
36. WearHttp new WearGetText(MainActivity.this).get("http://example.com/text.txt", new WearGetText.WearGetCallBack() { @Override public void onGet(String contents) { mTextView.setText(contents); } @Override public void onFail(final Exception e) { mTextView.setText(e.getMessage()); } });
37. AndroidWearScripts github.com/tajchert/AndroidWearScripts
38. AndroidWearScripts adb forward tcp:4444 localabstract:/adb-hub adb connect localhost:4444 adb -s localhost:4444 <command> ./main.sh <optional Id> ./screenshot.sh ./install.sh <apk_file> ./listPackages.sh ...
39. Exception handling goo.gl/o46Z1u
40. Exception handling <service android:name=".wear.service.ErrorService" android:process=":error"/> public class WearableApp extends Application { private Thread.UncaughtExceptionHandler mWearUEH = new Thread.UncaughtExceptionHandler() { public void uncaughtException(final Thread thread, final Throwable ex) { //... startService(errorIntent); } }; @Override public void onCreate() { Thread.setDefaultUncaughtExceptionHandler(mWearUEH); } } goo.gl/o46Z1u
41. Sensors
42. • Acceleration (m/s2) • Magnetic Field (μT) • Gyroscope (rad/s) • Proximity (cm) Sensors • Temperature (°C) • Pressure (hPa) • Humidity (%) • Light (lx) • Heartrate
43. Sensors - calculated • Acceleration (m/s2) • Magnetic Field (μT) • Gyroscope (rad/s) • Proximity (cm) • Temperature (°C) • Pressure (hPa) • Humidity (%) • Light (lx) • Heartrate • Steps • Significant Motion • Gravity • Linear Acceleration • Vector Rotation (x3)
44. Magnetic Field - location, field strength
45. Gyroscope - rate or rotation (rad/s)
47. Continuity
48. Views
49. Problem?
50. WearViewStub
51. BoxInsetLayout
52. CircledImageView
53. DismissOverlayView
54. DelayedConfirmationView
55. DelayedConfirmationView
56. GridViewPager
57. CardFragment
58. CardFrame
59. GridViewPager- has beautiful background with parallax effect Here be dragons... isRound() - works only with English language. which sometimes disappears.
