get current location without internet - phonegap geolocation api for android

Question

I am trying to get the user's current location using phonegap Geolocation api, which says "Common sources of location information include Global Positioning System (GPS) and location inferred from network signals such as IP address, RFID, WiFi and Bluetooth MAC addresses, and GSM/CDMA cell IDs". I am able to properly get the location when internet is ON (irrespective of the state of GPS). Is there a way to get the location using triangulation when the internet is OFF or not accessible? (GPS might be ON or OFF)

Answer 1

A BIG "NO"! This is like cutting down hands and asking if I could clap now? GPS and NETWORK location providers are the only way to receive user device location.

For GPS location - you need GPS sensors to be ON.

And for NETWORK location you need to have internet connection ON, because in this case the location is calculated on the basis of Cell-Tower/Wifi-spot ID which is then sent to google servers (via internet) to fetch the location details of the respective Cell Tower or wifi spot. Google's location server have its own location approximation algorithms on the basis of which it tells your location.

So, there could be no way you could receive a location when both GPS and INTERNET are OFF.

Note: You can still get the last received location from any of these providers by using LocationManager's getLastKnownLocation() even when the providers are OFF. But this locations are usually outdated ones and are barely of any use.
