Answer 1

You can't enable GPS for a user, what you can do is, if GPS s disabled, prompt the user with a message to ask him to enable GPS and send him to the settings to enable it

with this code :

Intent gpsOptionsIntent = new Intent(  
    android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);  
startActivity(gpsOptionsIntent);

This is a more detailed code on how to do it

To get the location you do this

    locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);

  /*try to see if the location stored on android is close enough for you,and avoid rerequesting the location*/
    Location location =  locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);

    if (location == null
            || location.getTime()
                    - Calendar.getInstance().getTimeInMillis() > MAX_LAST_LOCATION_TIME)
    {

        locationManager.requestLocationUpdates(
                LocationManager.GPS_PROVIDER, TIME_INTERVAL, LOCATION_INTERVAL, yourLocationListener);

    }
    else
    {
        //do your handling if the last known location stored on android is enouh for you
    }

in yourLocationListener, you implement what to do when you get the location
