推荐答案

如果您服务您的活动添加接收和获取数据。我想补充的活动及以下服务类。

If you add receiver in service and get data from your activity. I add Activity and Service class below.

这是你的主要活动时，你从服务接收数据。

This is your main activity when you get receive data from service.

public class YourActivity extends Activity {
private MyReceiver receiver;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    LocalBroadcastManager manager = LocalBroadcastManager.getInstance(this);
    receiver = new MyReceiver();
    IntentFilter filter = new IntentFilter(YourServices.ACTION);
    manager.registerReceiver(receiver, filter);

    if (!YourServices.isRunning) {
        startService(new Intent(this, YourServices.class));
    }
}

class MyReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction() != null) {
    if (intent.getAction().equals(YourServices.ACTION)) {
    AlarmManager service = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    Intent i = new Intent(context, MyServiceReceiver.class);
    PendingIntent pending = PendingIntent.getBroadcast(context, 0, i,PendingIntent.FLAG_CANCEL_CURRENT);
    Calendar cal = Calendar.getInstance();
    // Start 20 seconds after boot completed
    cal.add(Calendar.SECOND, 20);
    Log.v("background service", "STARTED////\\");

    //
    // Fetch every 1 hour
    // InexactRepeating allows Android to optimize the energy consumption
    service.setInexactRepeating(AlarmManager.RTC_WAKEUP,
            cal.getTimeInMillis(), REPEAT_TIME, pending);
            }
        }
    }
}
}

下面您服务，启动时发送数据。

Here your service that send data when starting.

public class YourServices extends Service {

public static String ACTION = "your_action";
public static boolean isRunning = true;

private void broadcastData() {
    Intent intent = new Intent(ACTION);
    LocalBroadcastManager.getInstance(getApplicationContext())
            .sendBroadcast(intent);
}

@Override
public IBinder onBind(Intent intent) {
    return null;
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    broadcastData();
    return START_STICKY;
}
}
