By getting the getLastKnownLocation you do not actually initiate a fix yourself   Be aware that this could start the provider  but if the user has ever gotten a location before  I don t think it will  The docs aren t really too clear on this   According to the docs getLastKnownLocation      Returns a Location indicating the data from the last known location   fix obtained from the given provider  This can be done without   starting the provider    Here is a quick snippet   import android content Context  import android location Location  import android location LocationManager  import java util List   public class UtilLocation       public static Location getLastKnownLoaction boolean enabledProvidersOnly  Context context           LocationManager manager    LocationManager  context getSystemService Context LOCATION SERVICE           Location utilLocation   null          List lt String gt  providers   manager getProviders enabledProvidersOnly           for String provider   providers                utilLocation   manager getLastKnownLocation provider               if utilLocation    null  return utilLocation                    return null            You also have to add new permission to AndroidManifest xml   lt uses-permission android name  android permission ACCESS FINE LOCATION    gt

What you are looking to do is get the position using the LocationManager NETWORK PROVIDER instead of LocationManager GPS PROVIDER  The NETWORK PROVIDER will resolve on the GSM or wifi  which ever available  Obviously with wifi off  GSM will be used  Keep in mind that using the cell network is accurate to basically 500m    http   developer android com guide topics location obtaining-user-location html has some really great information and sample code   After you get done with most of the code in OnCreate    add this      Acquire a reference to the system Location Manager LocationManager locationManager    LocationManager  this getSystemService Context LOCATION SERVICE       Define a listener that responds to location updates LocationListener locationListener   new LocationListener         public void onLocationChanged Location location             Called when a new location is found by the network location provider        makeUseOfNewLocation location              public void onStatusChanged String provider  int status  Bundle extras          public void onProviderEnabled String provider          public void onProviderDisabled String provider              Register the listener with the Location Manager to receive location updates locationManager requestLocationUpdates LocationManager NETWORK PROVIDER  0  0  locationListener     You could also have your activity implement the LocationListener class and thus implement onLocationChanged   in your activity

No  you cannot currently get location without using GPS or internet    Location techniques based on WiFi  Cellular  or Bluetooth work with the help of a large database that is constantly being updated  A device scans for transmitter IDs and then sends these in a query through the internet to a service such as Google  Apple  or Skyhook  That service responds with a location based on previous wireless surveys from known locations  Without internet access  you have to have a local copy of such a database and keep this up to date  For global usage  this is very impractical    Theoretically  a mobile provider could provide local data service only but no access to the internet  and then answer location queries from mobile devices  Mobile providers don t do this  no one wants to pay for this kind of restricted data access  If you have data service through your mobile provider  then you have internet access    In short  using LocationManager NETWORK PROVIDER or android hardware location network to get location requires use of the internet    Using the last known position requires you to have had GPS or internet access very recently  If you just had internet  presumably you can adjust your position or settings to get internet again  If your device has not had GPS or internet access  the last known position feature will not help you    Without GPS or internet  you could     Take pictures of the night sky and use the current time to estimate your location based on a star chart  This would probably require additional equipment to ensure that the angles for your pictures are correctly measured   Use an accelerometer to track location starting from a known position  The accumulation of error in this kind of approach makes it impractical for most situations
