I am using Fused Location Api for getting the latitude and longitude.It's mentioned in the documents that it uses GPS,Wifi and network to return the most accurate location of the user.I want to ask is that will it return the position if the GPS in my phone is switched off?
Fused Location Provider will automatically choose the best location from the options available. It will select from GPS or Network location Provider. So if the device GPS is not on, you should still be able to get a location based on the network location provider, if that is enabled on the device.
You will need to have permissions for ACCESS_FINE_LOCATION and ACCESS_COARSE_LOCATION to receive both kinds of locations.

My question is can you get location coordinates latitude and longitude using WIFI or any other source when location is off or disabled. Basically I want to get current location when the GPS is not enabled
If location permission isn't granted or location settings are off, no. That's on purpose- the user doesn't want to give you their location, respect that. Now if it's just GPS but not location that's off you can use coarse location. That uses wifi only, is less accurate, but can be used with less battery drain than GPS.
I need accurate location updates. When using FusedLocationServices from GooglePlayServices, even if I set HighAccuracy, it will get locations from Wi-Fi and cellular when GPS is not available. How do I request locations ONLY from GPS, and with no updates coming in when GPS is not available?
Use LocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, ...)
this removed the need for GooglePlayServices.Location completely.
Do i need phone location enabled ( api >19 ,lolipop and marshmallow) to get coarse location( network provider) ? I searched for a clear answer but i still do not get it. I cant get my location on google maps. I wonder if i get my location with coarse location do i still need the location enable ( Not gps enable from older phones <19 ) with coarse location permission.
No, you can refer [Android Location Providers - GPS or Network Provider?.
Phone location (gps) requires ACCESS_FINE_LOCATION. If ACCESS_COARSE_LOCATION is used, the location will be retrieved from network provider only.
And I think no new change has been made in API above 19.
I am writing an services which suggest near by facilities
I am using fuseAPI and asking for last known location so that i can suggest at least something. If I am asking user to on GPS he is uninstalling app.
I have used standard code of google to get last known location I thought it will give last known location even if user off GPS.
Google API let you choose location provider, GPS or Network (Access Point, if supported).
The way to do this it using LocationManager.NETWORK_PROVIDER
In additional, You can check if the provider is enabled (if your AP support location) with isProvideEnabled method:
boolean isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
AFAIK, fused location provider can use network or gps data depending on different conditions. Is it possible to find which exact location data source (WiFi, Cellular, GPS) was used after getting location with fused location provider? All I want is to show some notification on screen about the source of location data, like it's done in 2Gis app.
No,
Fused location provider:
The Fused Location Provider intelligently manages the underlying location technology and gives you the best location according to your needs.
It may use combo of that data.
