I am working on an application that requires an approximate position
of the user, so basically i am fine with any relatively recent
location data i can get. However I can't seem to get things right
using mock location data and would therefore appreciate your help.
The method i'm having tries to set mock location data for the gps
provider and tries to later retrievie it BUT:
locationManager.setTestProviderEnabled("gps", true); seems to fail
because i do not get any active location provider from the location
manager.
When I tried using a mock location provider with addTestProvider and
give it my mock location, the LocationManager returns me this mock
provider with getProviders(true) but then getLastKnownLocation returns
null instead of the provided mock location.
Here is my code (see comments as well):
private GeoPoint getUserLocation() {
LocationManager locationManager =
(LocationManager)getSystemService
(Context.LOCATION_SERVICE);
if (!PRODUCTION_ENVIRONMENT){
//Get some mock location data in the game
Location location = new Location("gps");
location.setLatitude(32.64480);
location.setLongitude(-16.90967);
location.setTime(new Date().getTime());
locationManager.setTestProviderLocation("gps",
location);
locationManager.setTestProviderEnabled("gps", true);
//retrieve the list of active providers for debugging
purposes, the
activated mock gps provider is not returned here
List<String> locationProviders =
locationManager.getProviders
(true);
locationManager.setTestProviderEnabled("network", true);
}
//i just want an approximate location so no high expectations
here
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_COARSE);
criteria.setPowerRequirement(Criteria.NO_REQUIREMENT);
//this correctly retrieves a mock location provider but not the
mock
enabled gps
String provider =
locationManager.getBestProvider(criteria,true);
if (provider != null) {
//this is where the mock provider returns null
Location location =
locationManager.getLastKnownLocation(provider);
return new
GeoPoint((int)(location.getLatitude()*E6_LATLONG), (int)
(location.getLongitude()*E6_LATLONG));
}else return null;
}
}
Thanks for any hints or requests for clarification!
