        Load package name(s) containing location provider support.
        These packages can contain services implementing location providers:
        Geocoder Provider, Network Location Provider, and
        Fused Location Provider. They will each be searched for
        service components implementing these providers.
        The location framework also has support for installation
        of new location providers at run-time. The new package does not
        have to be explicitly listed here, however it must have a signature
        that matches the signature of at least one package on this list.
