我正在使用Service在Google Glass中开发一个简单的hello world应用程序。在我的应用程序中,我使用 TimelineManager来显示LiveCard 。我希望在应用对用户可见时调用http调用(我的意思是当用户从其他应用滚动到我们的应用时)。
我知道如果我们使用Activity,自动调用onResume(),但我在服务中这样做。
请让我知道当应用恢复为用户时将调用哪种方法。
public class MyGlassService extends Service {
private static final String TAG = "SocketService";
private static final String LIVE_CARD_ID = "livecard";
private TimelineManager mTimelineManager;
private LiveCard mLiveCard;
private TextToSpeech mSpeech;
private final IBinder mBinder = new MainBinder();
private TextView txtName, txtBalance;
private RemoteViews remoteView;
private WakeLock screenLock;
public class MainBinder extends Binder {
public void sayMessage() {
mSpeech.speak(getString(R.string.hello_world),
TextToSpeech.QUEUE_FLUSH, null);
}
}
@Override
public void onCreate() {
super.onCreate();
mTimelineManager = TimelineManager.from(this);
mSpeech = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
@Override
public void onInit(int status) {
// do nothing
}
});
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
remoteView = new RemoteViews(this.getPackageName(), R.layout.activity_main);
if (mLiveCard == null) {
mLiveCard = mTimelineManager.createLiveCard(LIVE_CARD_ID);
remoteView.setTextViewText(R.id.name, getString(R.string.pre_screen_msg));
mLiveCard.setViews(remoteView);
}
return START_STICKY;
}
@Override
public void onDestroy() {
if (mLiveCard != null && mLiveCard.isPublished()) {
mLiveCard.unpublish();
mLiveCard = null;
}
mSpeech.shutdown();
mSpeech = null;
super.onDestroy();
}
@Override
public IBinder onBind(Intent intent) {
return mBinder;
}
public String toHexString(byte[] data) {
String s = new String(data);
return s;
}
}

实时卡片不提供精确的生命周期方法,例如活动可以让您知道用户何时滚动或远离某个活动。
