问题 I want to create an online map for a hiking trail, and I have been using my smartphone to collect coordinates from it. I have many questions regarding what's good practice when it comes to making such tracks, but for starters: it would look much neater if I could edit the readings so that they are right on top any roads in Google Maps. How can I achieve this? EDIT: I want to find the coordinates that will make a track along a road look exactly as if I'm using snapping/directions even when I'm

问题 I am using iOS SDK 4.2 and followed this tutorial: http://mobileorchard.com/hello-there-a-corelocation-tutorial/, and got some GPS logs happening on the console using both iPhone and iPad. Then I ran it on the simulator to test other features and the CoreLocation logs were hitting the locationManager:didFailWithError: method which is fair because the MacBookPro (OSX 10.6.6) has no GPS functionality... or so I thought. This morning I tested it on the iPad again at work instead of at home and

问题 I've created an android app that is so far working quite well. It contains a local service which is responsible for getting the users location every couple of minutes and relaying that via UDP to a collection server which is in turned displayed on a web application map. The app needs to be constantly running unless the user explicitly signs out of the application. Currently, it seems the OS is shutting down the service and restarting it as needed. I can see this because normally it would

问题 I am able to implement a simple gpsTracker using a service that runs on background like this: public class MyService extends Service { private static final String TAG = "BOOMBOOMTESTGPS"; private LocationManager mLocationManager = null; private static final int LOCATION_INTERVAL = 1000; private static final float LOCATION_DISTANCE = 10f; private final IBinder mBinder = new LocalBinder(); private Intent intent; Context context; Location mLastLocation; public class LocalBinder extends Binder {

问题 I would like to develop a app on the moto 360 that gets the users current gps coordinates, is this possible even though they say it doesnt have built in gps connectivity? The reason I ask is it also says you can "track your watches location".. How would this be possible if it doesnt have gps? Does it just use the host device for this? 回答1: Is this possible even though they say it doesnt have built in gps connectivity? Yes it is possible, based on the document "Detecting Location on Android

问题 I have upload my app to itunes yesterday and i receive a mail from the apple that is: From Apple 2. 5 Performance: Software Requirements Guideline 2.5.4 - Performance - Software Requirements We noticed that your app declares support for location in the UIBackgroundModes key in your Info.plist file but does not have any features that require persistent location. Specifically, your app uses location background mode for the sole purpose of tracking employees, which is not appropriate on the App
