问题
I'm wondering for the fused location, does any of the above use a combination of gps + wifi network together? what is the difference in terms of provider (does any of it uses the gps)? from what i see in the documentation the difference is only distance
I've previously worked with LocationManager and used NETWORK_PROVIDER and GPS_PROVIDER together to get a combination of those two provider.

The new fused location providers take a slightly different approach compared to previous methods. Developers now choose how much battery power is used to calculate a location instead of which device components are used to calculate it. It uses any available combination of GPS, Wi-Fi, mobile networks, and onboard sensors to calculate the location.
The LocationRequest priority settings are now:
PRIORITY_NO_POWER(passively listens for location updates from other clients)PRIORITY_LOW_POWER(~10km "city" accuracy)PRIORITY_BALANCED_POWER_ACCURACY(~100m "block" accuracy)PRIORITY_HIGH_ACCURACY(accurate as possible at the expense of battery life)
Google describes the LocationRequest class here: https://developers.google.com/android/reference/com/google/android/gms/location/LocationRequest
