4. is fused provider best choice android location? there negative points it?

what opinion? in advance.

when gps off , set priority high, mean gps automatically turned on, or not?

no, not turned on automatically. if use settingsapi, prompt dialog user , gives information gps must turned on. if user accepts it, gps active automatically. check settingsapi

how can know fused provider using (is gps or network provider)

if use fused provider api settingsapi properly. make adequate required settings current location request.

is fused provider best choice android location? there negative points it?

in opinion, before fused provider must deal directly providers(gps, network) fused asks you, "how accurate locations wanna receive ?"
