1. Android Wear 2.0 New level of freedom for your action Докладчик: Constantine Mars Senior Developer @ DataArt, Co-Organizer @ GDG Dnipro +ConstantineMars
3. David Singleton, VP Engineering at Google
5. So… What’s coming in Android Wear 2.0?
6. Problem No.1: Tethering
7. Freedom from tethering means “freedom without phone”
8. Officially supported by: • LGE Watch Urbane 2nd Edition • Huawei Watch Android Wear 2.0 Preview is available for
9. Upcoming: access Market directly from watch
10. What makes custom Watch Faces different but at the same time similar?
11. Complications - “any feature in a timepiece beyond the simple display of hours and minutes” (Wikipedia)
12. • Short text • Long text • Range of values • Icon (small picture) • Image (big picture) Complication types:
13. Complications coding
14. Each complication should have unique id private static final int LEFT_DIAL_COMPLICATION = 0; private static final int RIGHT_DIAL_COMPLICATION = 1; public static final int[] COMPLICATION_IDS = {LEFT_DIAL_COMPLICATION, RIGHT_DIAL_COMPLICATION}; // Left and right dial supported types. public static final int[][] COMPLICATION_SUPPORTED_TYPES = { {ComplicationData.TYPE_SHORT_TEXT}, {ComplicationData.TYPE_SHORT_TEXT} };
15. ComplicationData type stores complication info (text, icon, type) onComplicationDataUpdate() is initiated by Data Provider private SparseArray<ComplicationData> mActiveComplicationDataSparseArray; … @Override public void onComplicationDataUpdate( int complicationId, ComplicationData complicationData) { Log.d(TAG, "onComplicationDataUpdate() id: " + complicationId); // Adds/updates active complication data in the array. mActiveComplicationDataSparseArray.put(complicationId, complicationData); invalidate(); }
16. Rendering complications private void drawComplications(Canvas canvas, long currentTimeMillis) { // onDraw() for (int i = 0; i < COMPLICATION_IDS.length; i++) { ComplicationData complicationData = mActiveComplicationDataSparseArray.get(COMPLICATION_IDS[i]); if ((complicationData != null) && (complicationData.isActive(currentTimeMillis)) && (complicationData.getType() == ComplicationData.TYPE_SHORT_TEXT)) { ComplicationText mainText = complicationData.getShortText(); canvas.drawText( mainText, 0, mainText.length(), complicationsX, mComplicationsY, mComplicationPaint);
17. Data Providers will stand behind the scenes as sources of data for complications
18. One complication may use different providers as the data source
19. DataProviders coding
20. Extend ComplicationProviderService and declare it in AndroidManifest.xml android.support.wearable.complications.ACTION_COMPLICATION_UPDATE_REQUEST android:icon android.support.wearable.complications.UPDATE_PERIOD_SECONDS android.support.wearable.complications.PROVIDER_CONFIG_ACTION <meta-data android:name="android.support.wearable.complications.SUPPORTED_TYPES" android:value="SHORT_TEXT"/>
21. ComplicationProviderService internals onComplicationActivated() onComplicationUpdate() onComplicationDeactivated()
22. Exposing data from provider in onComplicationUpdate() @Override public void onComplicationUpdate(int complicationId, int dataType, ComplicationManager complicationManager) { int randomNumber = (int) Math.floor(Math.random() * 10); String randomNumberText = String.format(Locale.getDefault(), "%d!", randomNumber); switch (dataType) { case ComplicationData.TYPE_SHORT_TEXT: ComplicationData complicationData = new ComplicationData.Builder(ComplicationData.TYPE_SHORT_TEXT) .setShortText(ComplicationText.plainText(randomNumberText)) .build(); break; ...
23. Exposing data from provider Trigger update with ComplicationManager.updateComplicationData() @Override public void onComplicationUpdate(int complicationId, int dataType, ComplicationManager complicationManager) { ... if (complicationData != null) { complicationManager.updateComplicationData(complicationId, complicationData); }
24. What whas really distracting in AndroidWear 1.X notifications? White light when you receive notification
25. Visual updates to notifications in 2.0 Dark theme, Material Design for Android Wear
26. Large dark notification Easier to read, but less-distracting in everyday life
27. Notifications and messages
28. Notification MessagingStyle
29. Allow smart replies, based on Google Assistant NotificationCompat.Action action = new NotificationCompat.Action.Builder(R.drawable.ic_reply_icon, getString(R.string.label), replyPendingIntent) .addRemoteInput(remoteInput) // 1) allow generated replies .setAllowGeneratedReplies(true) .build();
30. Use MessagingStyle for notification Notification noti = new NotificationCompat.Builder() .setContentTitle(messages.length + " new messages with " + sender.toString()) .setContentText(subject) .setSmallIcon(R.drawable.new_message) .setLargeIcon(aBitmap) // 2) set the style to MessagingStyle .setStyle(new NotificationCompat.MessagingStyle(resources.getString(R.string.reply_name)) .addMessage(messages[0].getText(), messages[0].getTime(), messages[0].getSender()) .addMessage(messages[1].getText(), messages[1].getTime(), messages[1].getSender()))
31. Response to notifications in AndroidWear 1.X “Voice input”
32. More input methods Handwriting, suggestions, keyboard
33. 1.38-inch full circle P-OLED 480 x 480 348ppi How full-size keyboard works on the small screen?
34. “Magic button” - center of navigation concepts
35. The most complicated UI pattern of AndroidWear 1.X? - “2D Picker”
36. The answer to this problem in AndroidWear 2 - Recommended pattern is “1D Layouts”
37. App Layout examples
38. Material Design: Navigation and Action Drawers
39. WearableDrawerLayout and it’s internals <android.support.wearable.view.drawer.WearableDrawerLayout ...> <FrameLayout .../> <android.support.wearable.view.drawer.WearableNavigationDrawer .../> <android.support.wearable.view.drawer.WearableActionDrawer .../> </android.support.wearable.view.drawer.WearableDrawerLayout>
40. Material Design: Navigation and Action Drawers
41. Material Design: Dark Theme
42. Android Wear Area at Google I/O
43. GoogleFit infrastructure
44. Well known GoogleFit APIs
45. GoogleFit: upcoming APIs
46. GoogleFit: upcoming features of existing APIs
47. GoogleFit - gym activity recognition
48. GoogleFit live demo on Google I/O
49. Activity recognition accuracy
