There are two sets of APIs - one provided by Android AOSP where you choose whether you use GPS, network location or other provider and handle it manually.
And then there's a more powerful version provided by Google Services, which automatically fuses all providers and talks to Google servers. Most apps these days opt for the Fused provider, since it's easier to use and automatically handles getting a reliable location in pretty much any environment. It's not available on "Google-free" phones though, since it depends on Google's infrastructure.
