问题 I'm creating an application (For educational purposes) which records the user's location every 30 minutes, and enables the user the view all the locations on the map. I don't want updates to be more frequent than 30 minutes, but they are. This is how I call requestLocationUpdates : locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 30 * 60 * 1000, 0, pe); Now, the documentation clearly says: The elapsed time between location updates will never be less than minTime But I did

问题 i am making an android app using geo-location in android. i am using the location manager for getting the geo-location coordinates. locationManager.requestLocationUpdates(provider, 0, 0, this); Location location = locationManager.getLastKnownLocation(provider); and using the postDelayed() function for continuously called the getLastKnownLocation() for the geo-location. and set the interval timing 1000 (1 sec). but i get the response after 20 seconds.

问题 I got this error from the user logs on an android app I created. I have been unable to replicate the error thus far. Any help would be extremely appreciated. The error is: java.lang.IllegalArgumentException: provider=gps at android.os.Parcel.readException(Parcel.java:1326) at android.os.Parcel.readException(Parcel.java:1276) at android.location.ILocationManager$Stub$Proxy.requestLocationUpdates(ILocationManager.java:646) at android.location.LocationManager._requestLocationUpdates

问题 This seems like it should be simple enough, but I can't seem to get a clear example of how to calculate my speed using Android's Location Services. All I want to do is calculate my speed based on my previous and current GPS position. getSpeed() doesn't work, because it needs to be set at some point using setSpeed(). So is there any sample code out there that I can run in Eclipse against my Android emulator running a GPX file, that will show me my pace in any measure (meters, feet, miles, etc.

问题 I am looking at LocationManager to get best location for periodical reporting location. I am curious about LocationManager.requestLocationUpdates method. What would it happen if I invoke this method several times with different minTime and minDistance without calling removeUpdates? Will it add new request or just update the existing one? I am trying to test this, it is not bit easy at the moment. Your answer would be appreciated. 回答1: It will update the existing request. 回答2: You could

问题 I have some problems with location systems. I have a service that implements locationlistener. I want to get the best location using network when possible, gps if network is not enough accurate (accuracy greater than 300mt). The problem is this. I need location (accurate if possible, inaccuarte otherways) every 5 minutes. I start with a : LocationManager lm=(LocationManager)getApplicationContext().getSystemService(LOCATION_SERVICE); Criteria criteria = new Criteria(); criteria.setAccuracy

问题 I'm trying to get the current location in android using LocationManager and LocationListener as described at http://developer.android.com/guide/topics/location/obtaining-user-location.html However, onLocationChanged method of the LocationListener is never called. I've used a real android phone / also used the emulator and simulated location changed using telnet, as described in the link above. Here's my code: public class MyActivity extends Activity { @Override public void onCreate(Bundle

问题 Before I go into location based mode I check for existence of any location providers by calling List<String> android.location.LocationManager.getProviders(boolean enabledOnly) //enabledOnly = true and checking the size of the resulting list. Now I tested my App on a HTC Desire with Android 2.2. The system settings don't allow any location tracking (GPS and mobile is turned off). However, the list get returned has 1 entry, whose value is "passive". What is it? Can I work with it? The provider

问题 I've created a Service and grabs location data about the user so I can show my users nearby places. I want this Service to track by network in addition to GPS for 2 reasons: 1) GPS may not be enabled. 2) GPS takes quite a bit of time to lock on with my test phone. When my Service executes the following line: mNETEnabled = mLocationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER); I get the following error: 11-24 14:00:41.693: ERROR/LocationManagerService(51): isProviderEnabled got
