29. What You Can Do
30. Pretty Much Everything in Android + import support.wearable.* What You Can Actually Do
31. Get Started
33. Android Studio
34. Notifications
36. Extended Notifications
37. Actions
38. Actions – Code I // Create an intent for the reply action Intent actionIntent = new Intent(this, ActionActivity.class); PendingIntent actionPendingIntent = PendingIntent.getActivity(this, 0, actionIntent, PendingIntent.FLAG_UPDATE_CURRENT); // Create the action NotificationCompat.Action action = new NotificationCompat.Action.Builder(R.drawable.ic_action, getString(R.string.label), actionPendingIntent) .build();
39. Actions – Code II // Build the notification and add the action via WearableExtender Notification notification = new NotificationCompat.Builder(mContext) .setSmallIcon(R.drawable.ic_message) .setContentTitle(getString(R.string.title)) .setContentText(getString(R.string.content)) .extend(new WearableExtender().addAction(action) .build();
40. Voice Input
41. Voice Input – Code I /* Obtain the intent that started this activity by calling Activity.getIntent() and pass it into this method to get the associated voice input string.*/ private CharSequence getMessageText(Intent intent) { Bundle remoteInput = RemoteInput.getResultsFromIntent(intent); if (remoteInput != null) { return remoteInput.getCharSequence(EXTRA_VOICE_REPLY); } return null; }
42. Pages
43. Pages – Code I // Create builder for the main notification NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) .setSmallIcon(R.drawable.new_message) .setContentTitle("Page 1") .setContentText("Short message") .setContentIntent(viewPendingIntent);
44. Pages – Code II // Create a big text style for the second page BigTextStyle secondPageStyle = new NotificationCompat.BigTextStyle(); secondPageStyle.setBigContentTitle("Page 2") .bigText("A lot of text..."); // Create second page notification Notification secondPageNotification = new NotificationCompat.Builder(this) .setStyle(secondPageStyle) .build();
45. Pages – Code III // Add second page with wearable extender and extend the main notification Notification twoPageNotification = new WearableExtender() .addPage(secondPageNotification) .extend(notificationBuilder) .build(); // Issue the notification notificationManager = NotificationManagerCompat.from(this); notificationManager.notify(notificationId, twoPageNotification);
46. Stacking
47. Stacking – Code I final static String GROUP_KEY_EMAILS = "group_key_emails"; // Build the notification, setting the group appropriately Notification notif = new NotificationCompat.Builder(mContext) .setContentTitle("New mail from " + sender1) .setContentText(subject1) .setSmallIcon(R.drawable.new_mail) .setGroup(GROUP_KEY_EMAILS) .build();
48. Stacking – Code II // Issue the notification NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this); notificationManager.notify(notificationId1, notif); Notification notif2 = new NotificationCompat.Builder(mContext) .setContentTitle("New mail from " + sender2) .setContentText(subject2) .setSmallIcon(R.drawable.new_mail) .setGroup(GROUP_KEY_EMAILS) .build(); notificationManager.notify(notificationId2, notif2);
