I only need the last known gps location from any provider  

without telling any provider to update. 

Is this possible without adding listeners or requestLocationUpdates? 

The thing is i need only an approximate position without blocking delay 

Im trying this code from an `Activity` `onCreate` but the `providers.size()` is always zero

```
LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);  
List<String> providers = lm.getProviders(true);

    Location l = null;

    for (int i=providers.size()-1; i>=0; i--) {
       l = lm.getLastKnownLocation(providers.get(i));
       if (l != null) 
        break;
    }
