Is there something wrong with this code?
You are not checking to see if myLoc
is null
. getLastKnownLocation()
does not have to return a non-null
value.

I test my apps on two phones (1) an LG Optima running 2.3.7 and (2) a galaxy S3 running 4.1.2. The following code always works on the LG and always fails with a nullPointerException on the Galaxy..
try { //sometimes getting the last known location gets a nullpointerexception
String locationProvider = LocationManager.GPS_PROVIDER;
locMgr = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
Location myLoc = locMgr.getLastKnownLocation(locationProvider);
CameraUpdate center = CameraUpdateFactory.newLatLng(new LatLng(myLoc.getLatitude(), myLoc.getLongitude()));
map.animateCamera(center);
DebugLog.debugLog("Instantiated new Location listener. Moved camera to: " + myLoc.getLatitude() + myLoc.getLongitude() , false);
} catch (Exception e) {
DebugLog.debugLog("Exception getting lastknownlocation - doing without" + e, false);
}
Is there something wrong with this code? Thanks, Gary
