location

问题 Im trying to get an adress trough the gps, converting the coordinates to my location. I am using this code: latitude1 = (location.getLatitude()); longitude2= (location.getLongitude()); JSONObject ret = getLocationInfo(); JSONObject location2; String location_string; try { location2 = ret.getJSONArray("results").getJSONObject(0); location_string = location2.getString("formatted_address"); Log.d("test", "formattted address:" + location_string); StringRua = (" " + location_string); } catch

问题 I need to create new geofence circles dynamically for each location I get from a Worklight Adapter. I need to do it using a loop, as I dunno how many locations are defined in backend service. Furthermore a new location can be define meanwhile the application is running. I have seen several samples for an established set of locations but I dunno how to get it working in my scenario... 回答1: I have already found a solution. This is the code in case someone needs it: var triggers = new Object();

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . I am working on an application which will be installed on around 50 devices. I will be getting the location of all those 50 users in every 5 minutes. I have a small concept tell me if it's possible or not. And if possible how do i implement that? So it goes like this we have the location co-ordinates i.e.

问题 I am getting two GEO locations in my application and I have to calculate distance between them and after distance calculation I have to compare that result with the a defined threshold which is in my case 50 meters , how would I define that threshold in float. Also, Currently I my android fone is at the same location, but I always get the calculated distance between my 2 two geolocations determined after an interval to be more than 50 meters. How is it possible? I am taking threshold of 50

问题 I want to get the current location working with both online or offline GPS as well the expected behavior of the GPS is: 1. If wifi or 3g networks are available, it will use those to fetch the GPS position. 2. If NO wifi or 3g networks are avaiable it will use the OFFLINE GPS of the tablet (if present) 3. If nothing is present, it will display the Error message. I am trying a lot but not succeeded yet. I am getting network enabled always true. public boolean isGPSEnabled() { Location location

问题 Im working on a reminder which also supports location-based reminders (eg when you get near your house it tells you to switch off the alarm for example).. I need the app to check the location lets say every 2 minutes (so it doesnt drain the battery too much). What technology should I use? I was thinking about toast notifications but this is to remind the user the he is approaching the location, but there needs to be a background task which checks the location even if the app is not running?

问题 I am developing small location based android application in which I need users current location. I am also updating users current location as soon as some change in location is occurred.My code looks like: private final LocationListener locationListener = new LocationListener() { public void onLocationChanged(Location location) { updateWithNewLocation(location); } public void onProviderDisabled(String provider) {} public void onProviderEnabled(String provider) {} public void onStatusChanged

问题 I am developing an application that shows the distance between the user and multiple locations (such as foursquare in the image below) on android, I am using eclipse and would like to know how to calculate the distance between various points. Thank you! Image: http://i.stack.imgur.com/rsWmO.jpg 回答1: There are probably many ways to get this done, here's an option. You could use the distanceTo() method. If you want more than one distance, simply use a loop to repeat it until you've calculated
