wear-os

问题 When Android Wear goes to sleep mode (screen dimmed), some parts of my code are not executed. I use Timer in background service to trigger some actions, such as sending data from wear to mobile, but the data is not sent. It is sent when I tap the screen to wake it up. I also try to use Timer trigger a notification with vibration when the screen is off, but it doesn't appear until I tap the screen. In debug mode (either Bluetooth or USB), data sending and notification work fine. I suspect this

问题 I am trying to add Voice Capabilities in Android Wear and following below URL https://developer.android.com/training/wearables/apps/voice.html Here is my manifest <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.demowearapp" android:versionCode="1" android:versionName="1.0" > <uses-feature android:name="android.hardware.type.watch" /> <uses-permission android:name="android.permission.VIBRATE" /> <uses-sdk android

问题 I'm developing an app for Android Wear on Samsung Gear Live (Google I/O Edition) where it will need access heart rate and steps count history data. I know that later this data might be accessible using Google Fit SDK, but is it possible to read that data without using that SDK right now? I would prefer to access this data without ROOTing my G Watch. Here are the screenshots of the historical data that I would like to extract: Steps History data: Heart Rate History Data: UPDATE 10/28/2014

问题 I have been working on a project where I need a button on a mobile to start up an activity on the watch. I have been going through the data layer sample in the sdk but can not get it working. I set up a wearable listener service class, but it is not picking up any messages. The service is added to the manifest but it is still not working. I do have other services too and I am thinking I might have too many services. On the Wear watch, does an activity have to be running in order for it to

问题 Can Android Wearable apps detect the power button as a KeyEvent or by other means? I would like to run a listener service to detect the wearable power button. I tried this but no log corresponding to a KeyEvent occurred. @Override public boolean onKeyDown(int keyCode, KeyEvent event) { Log.e(">>>>>>", "FindPhoneActivity event "+event); if (keyCode == KeyEvent.KEYCODE_POWER) { // Do something here... Log.e(">>>>>>", "FindPhoneActivity onKeyDown"); //event.startTracking(); // Needed to track

问题 I'm trying to send a String array from my phone to my wear, I've created a service on my phone that is supposed to send the data with this code : public class SendDataService extends Service { private static final String TAG = "SendDataService"; @Override public void onCreate(){ GoogleApiClient mGoogleApiClient = new GoogleApiClient.Builder(this) .addConnectionCallbacks(new GoogleApiClient.ConnectionCallbacks() { @Override public void onConnected(Bundle connectionHint) { Log.d(TAG,

问题 I want to develop a health care app using Android smart watch devices that have an optical heart rate sensor. Examples of such devices are: Samsung gear live, Moto360, LG G watch R, etc. To do this, I need the raw PPG signal data from those devices, but I found that the Android API only supports heart rate data by BPM unit. Does anyone know if the raw signal data is accessible, and if so, how do I get access to that data? 回答1: Yes, it is possible (at least on a Samsung mobile device such as

问题 I'm trying to access the heart rate monitor of a Samsung Gear Live watch. The watch is paired with a 4.4.4 handset and works correctly. I'm following the official BasicSensorsApi sample. I can successfully connect to Google Play Services with the following scope: addScope(new Scope(Scopes.FITNESS_LOCATION_READ_WRITE)) .addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ_WRITE)) .addScope(new Scope(Scopes.FITNESS_BODY_READ_WRITE)) But then, when I want to list all available heart rate monitors, I

问题 I'm building a Wear app that will communicate with a WearableListenerService on the handheld. However, i want to make sure that service is up and running when the app starts on the watch. My initial thought was either send an intent or a broadcast message to get the service started. However, i've been unable to figure out how to get the watch to send that to the paired handheld instead. On the watch side: Intent intent = new Intent(); intent.setAction("my.wearable.CONNECT"); sendBroadcast

问题 Since last update Android Wear has a new feature - the always-on mode. This means that the Android Wear device doesn’t turn off the screen; it changes to the ambient mode to save battery and keeps certain apps running in the background. How exactly should I implement this? p.s. I'm developing sport application, not watchface. 回答1: What you're looking for is how to support "Ambient Mode" in your Wear app's activity. There is an entire doc dedicated to this: http://developer.android.com
