Use config_netowrkLocationProviderPackageName and config_geocodeProviderPackageName as intial packages. If another package exists (or is later installed) that also implements a provider, and has the same signatures as the original providers, and has a hgiher version number, then use that instead. The old code used a funky fix of package name substring checks and service checks that was broken and not upgradeable. Bug: 6499445 Change-Id: Ic58f09cf85d31d9abf47707093e22f31dda25cf0
