34. Creating live cards TimelineManager tm = TimelineManager.from(context); mLiveCard = tm.createLiveCard(LIVE_CARD_TAG); mLiveCard.setViews(new RemoteViews(context.getPackageName(), R.layout.card_text)); mLiveCard.publish(LiveCard.PublishMode.REVEAL); // or SILENT
35. Updating live cards mRemoteViews.setTextViewText(R.id.text, "new message"); mLiveCard.setViews(mRemoteViews); Removing live cards mLiveCard.unpublish();
