问题 I'm trying to add an AlarmManager to update a watch face on half minute intervals. This is for a ternary clock. This is my first time programming with Java or android studio. I'm following a guide at https://developer.android.com/training/wearables/apps/always-on.html The guide says to "declare the alarm manager and the pending intent in the onCreate() method of your activity" Should I use @Override public Engine onCreateEngine() { return new Engine(); } or @Override public Engine

问题 I have an app that interfaces extensively with the contacts ContentProvider . I am looking to introduce a Wear component to my app that will make use of contact data. Is Wear able to directly access the contacts through a ContentResolver or does it have to be manually synced from the mobile device? 回答1: There is no such an API allows you to directly read contacts of your phone. You may have to consider the wearable app as a separate app from you phone side app. You should sync the contacts

问题 I am developing an Android Wear Watchface that accesses the Internet by sending a MessageAPI request from wear to my mobile app, where I am running a WearableListenerService, and on my mobile app, I receive the request from wear in onMessageReceived, and in onMessageReceived I start an AsyncTask to retrieve an image from the Internet. This works all fine normally . However, if the phone is inactive for a few minutes (screen black, not connected to my mac via USB) I receive an "ECONNREFUSED -

问题 I have a wearable device from which data is sent to a handheld device wrapped in a DataMap object. On the handheld device I implemented a listener service that extends WearableListenerService implemented in this way: public class ListenerService extends WearableListenerService { private static final String TAG = ListenerService.class.toString(); private static final String WEARABLE_DATA_PATH = "/wearable_data"; @Override public void onDataChanged(DataEventBuffer dataEvents) { DataMap dataMap;

问题 I'm creating a watchface for Android Wear which will display calendar events. Based on this page (and the WatchFace sample provided in the SDK), I managed to query the next events for the day, and display them on my watchface (below is the code I use to query the events). The problem is that recurring events are not returned in the cursor, and thus are not displayed on the watch face. Is there any parameter to add in the query to get recurring events ? private static final String[] PROJECTION
