我已使用服务从网络定位提供商处收集修复。我没有使用 wacklock，但我的应用程序可以锁定设备。

我在 Battery Histor for GB 中看到过，例如： Screen ON: 2 minutes; 跑步：5分钟；我的应用程序的部分唤醒锁定：10 分钟。

它应该是？我只需要在设备唤醒时收集位置数据。

这是我的服务：

包 com.myapp.service；

 import com.myapp.App;
 import android.app.Service;
 import android.content.Context;
 import android.content.Intent;
 import android.location.Location;
 import android.location.LocationListener;
 import android.location.LocationManager;
 import android.location.LocationProvider;
 import android.os.IBinder;

 public class LocationMonitor extends Service
 {
/**********************
 * PUBLIC CONSTANTS
 **********************/
public static final String ACTION_START = "StartService"; // start action
public static final String ACTION_STOP = "StopService"; // stop action

/**********************
 * PRIVATE CONSTANTS
 **********************/
private static final long MINIMUM_DISTANCE_CHANGE = 10; // in Meters
private static final long MINIMUM_TIME_BETWEEN_UPDATES = 300 * 1000; // in Milliseconds

/**********************

private LocationManager sLocationManager; // location manager

/**********************
 * SERVICE LIFECYCLE
 **********************/
@Override
public void onCreate()
{
    super.onCreate();
    startService();
}

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

@Override
public int onStartCommand(Intent intent, int flags, int startId) 
{
    if (intent != null)
    {
        if (intent.getAction().equals(ACTION_STOP))
        {
            stopService();
            return START_NOT_STICKY;
        }
    }
    return START_STICKY;
}

private void startService()
{
    sLocationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    sLocationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 
        MINIMUM_TIME_BETWEEN_UPDATES, MINIMUM_DISTANCE_CHANGE, sNetworkLocationListener);
}

private void stopService()
{
    sLocationManager.removeUpdates(sNetworkLocationListener);
    stopSelf();
}

/**********************
 * LOCATION LISTENERS
 **********************/
private LocationListener sNetworkLocationListener = new LocationListener() 
{
    @Override
    public void onLocationChanged(Location location) 
    {
        // store location in db
    }

    @Override
    public void onProviderDisabled(String provider) {}

    @Override
    public void onProviderEnabled(String provider) {}

    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {}
};

/**********************
 * STATIC METHODS
 **********************/

public static void startService(Context context)
{
    Intent newIntent = getServiceIntent(context);
    newIntent.setAction(ACTION_START);
    context.startService(newIntent);
}

public static void stopService(Context context)
{
    Intent newIntent = getServiceIntent(context);
    newIntent.setAction(ACTION_STOP);
    context.startService(newIntent);
}
 }
