I discovered that in certain cases
getLocationEngine()can be called even if location component was not activated (possibly if someone tried to activate it before style was loaded), causing an unhandled exception (see #534). I have no idea why a getter call would ever need to crash, but here we are.I added
isLocationComponentActivated()check in every place wheregetLocationEngine()is called. It is not the most elegant solution for sure, but since there are other checks in place it seemed appropriate and allowed me to avoid wrapping the getter in another getter.I also added missing else branch in
getLastLocationcall handler. I chose "LOCATION DISABLED" as an error code since I could not find any standardized list of error codes. Feel free to suggest alternatives.
