java - GPS Application crash -

-

I have to write an application that does a lot of things including recording the user's GPS location, when a correct username and password Happens to enter I only want latitude and longitude in that exact moment, the recurring check of that nature or nothing. I think that whatever I was looking for, got anything like this:

However, Eclipse did not like the reference because I have not started it yet So that code of the whole code: 

  reference reference = getBaseContext (); LocationManager locMan = (LocationManager) context.getSystemService (context.LOCATION_SERVICE); Logs. I (getclass (). GetSimpleName (), called "Location Manager"); Location loc = locMan.getLastKnownLocation (LocationManager.GPS_PROVIDER); Logs. I (getclass (). GetSimpleName (), "get last known location"); Double latitude = loc.getLatitude (); Log.i (getClass () getSimpleName (), "Latitude:" + Latitude.); Double longitude = loc.getLongitude (); Log.i (GetClass () getSimpleName (), "Longitude:" + Longitude); Toast. Make Text (Reference, Latitude + "," + Longitude, Toast. LNNHHLAG). Show ();

and for permission in the manifest: 

  Use of Android - permission: name = "com.foxcatch.code.insecure.LOCATION_FINDER" /> ; & Lt; Usage-permission Android: name = "android.permission.ACCESS_FINE_LOCATION" /> & Lt; Usage-permission Android: name = "android.permission.ACCESS_COARSE_LOCATION" />

However, when I try to reach latitude and longitude and try to double them: 

  double latitude = loc.getLatitude () ; Double longitude = loc.getLongitude (); Here is the logcat error entry, this is slightly on my head:

 I I'm new to Droid, and I'm just trying to learn all this. Thanks for any help.   
 
 
 Why is getting the BaseContext .. just go directly  getSystemService  
 
  Change it:  
 
  Location Manager loc_en = (location manager) context.getSystemService (context.LOCATION_SERVICE); For
