title: Google Maps v2 - onclick listener does not respond after orientation changes
body: <p>I am using Google Maps V2 in my app and when I change orientation to landscape (or basically change th eorientation), the onMapClick method does not respond and does nto respond even after the orientaiton changes again. I know I could avoid this weird bug by setting configChange:orientation|screenSize , but then layouts of my dialogues do not change their layout from layout-portrait to layout-landscape when orientaiton changes. 
  This all is in one activity. Has anyone encountered this issue? What is wrong with the maps? I don´t understand where is the problem, why the listener should be unregistered.
  I register it in onCreateMethod:
          @Override
      protected void onCreate(Bundle savedInstanceState)
      {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);</p>
  
  <pre><code>    DisplayMetrics dm = getResources().getDisplayMetrics();
      screenWidth = dm.widthPixels;
      screenHeight = dm.heightPixels;
  
      FontUtils.setCustomFont(this, (ViewGroup) getWindow().getDecorView());
  
      RelativeLayout topBar = (RelativeLayout) findViewById(R.id.topBar);
      LinearLayout placeTextLayout =    (LinearLayout)topBar
                                                    .findViewById(R.id.placeTextLayout);
      placeTextView = (TextView) placeTextLayout.findViewById(R.id.placeText);
  
      sharedPrefs = getSharedPreferences
                                (SkyConstants.PREFS_NAME,Context.MODE_PRIVATE);
      String place = sharedPrefs.getString
                    (SkyConstants.PREF_LOCATION_ID,SkyConstants.PREF_LOCATION_DEFAULT);
  
      dateTextView = (TextView) topBar.findViewById(R.id.dateText);
      daysTextView = (TextView) topBar.findViewById(R.id.timeText);
  
      updateTopBar();
      setUpMapIfNeeded();
  }
  
  private void setUpMapIfNeeded()
  {
      if (mMap == null)
      {
          mMap = ((SupportMapFragment)getSupportFragmentManager()
                                                   .findFragmentById(R.id.map)).getMap();     
      }
      if (mMap != null)
      {
          mMap.getUiSettings().setZoomControlsEnabled(true);
          mMap.getUiSettings().setZoomGesturesEnabled(true);          
          mMap.setMapType(GoogleMap.MAP_TYPE_TERRAIN);
  
          mMap.setOnMapClickListener(new OnMapClickListener()
          {
              @Override
              public void onMapClick(LatLng point)
              {
              //do something  
  
              }
  
          });
      }
  }
  </code></pre>
