Here is the code using a mock location provider. Basically my question
is, why is the mock provider not returning the previously set mock
location correctly. See last comment in code:
private GeoPoint getUserLocation() {
LocationManager locationManager =
(LocationManager)getSystemService
(Context.LOCATION_SERVICE);
if (!PRODUCTION_ENVIRONMENT){
//Get some mock location data in the game
locationManager.addTestProvider(MOCK_PROVIDER_NAME,
true, false,
true, false, false, false, false, Criteria.POWER_LOW,
Criteria.ACCURACY_COARSE);
Location location = new Location(MOCK_PROVIDER_NAME);
location.setLatitude(32.64480);
location.setLongitude(-16.90967);
location.setTime(new Date().getTime());
locationManager.setTestProviderLocation(MOCK_PROVIDER_NAME,
location);
locationManager.setTestProviderEnabled(MOCK_PROVIDER_NAME, 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 the mock location provider
String provider = locationManager.getBestProvider(criteria,
true);
if (provider != null) {
//this is where the mock provider returns null ... why?
Location location =
locationManager.getLastKnownLocation(provider);
return new
GeoPoint((int)(location.getLatitude()*E6_LATLONG), (int)
(location.getLongitude()*E6_LATLONG));
}else return null;
}
Might this be a bug in the API?
