Android activate gps with AlertDialog: how to wait for the user to take action?

Question

I\'ve read different posts that there is no way to wait for the user to take an action when an AlertDialog is shown because it blocks the UI.

However,

Answer 1

I done that by using simple function but without displaying an alert box i redirected usercontrol to setting page

Here is the function i used

public void isGPSEnable(){
        LocationManager service = (LocationManager) getSystemService(LOCATION_SERVICE);
        boolean enabled = service
          .isProviderEnabled(LocationManager.GPS_PROVIDER);
        if (!enabled) {
          Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
          startActivity(intent);
        } 

}
