Fixed version (ground truth):
@Override public Please onEvent(BluetoothEnablerEvent e){
  if (e.nextStage() == Stage.BLUETOOTH) {
    return Please.doNext().withImplicitActivityResultHandling();
  }
 else   if (e.nextStage() == Stage.LOCATION_PERMISSION) {
    if (e.status() == Status.ALREADY_ENABLED || e.status() == Status.ENABLED) {
      if (!e.isEnabled(Stage.LOCATION_SERVICES) && !e.isEnabled(Stage.LOCATION_PERMISSION)) {
        return Please.doNext().withImplicitActivityResultHandling().withDialog("String_Node_Str");
      }
 else       if (!e.isEnabled(Stage.LOCATION_PERMISSION)) {
        return Please.doNext().withImplicitActivityResultHandling().withDialog("String_Node_Str");
      }
 else       if (!e.isEnabled(Stage.LOCATION_SERVICES)) {
        return Please.doNext().withImplicitActivityResultHandling().withDialog("String_Node_Str");
      }
 else {
        return Please.stop();
      }
    }
 else     if (e.status() == Status.CANCELLED_BY_DIALOG || e.status() == Status.CANCELLED_BY_INTENT) {
