title: google maps integration and SlidingMenu
body: <p>I want to implement Google maps v2 and SliderMenu of jfeinstein10, I managed to implement the SliderMenu but when I want to add the map in the activity, I get error</p>
  
  <p>GoogleMap map = ((SupportMapFragment) getSupportFragmentManager (). FindFragmentById (R.id.fragMapa)). GetMap ();</p>
  
  <p>being more specific in getSupportFragmentManager ()</p>
  
  <p>any solution for that integrate both. I put the code of the activity.</p>
  
  <pre><code>import android.app.FragmentTransaction;
  import android.os.Bundle;

          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_activity_principal);
  
          GoogleMap mapa = ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.fragMapa)).getMap();
  
          LatLng coordenadasGT = new LatLng(15.45368,-90.485115);
          CameraPosition camPos = new CameraPosition.Builder()
          .target(coordenadasGT)
          .zoom(8)
          .build();
  
          CameraUpdate camUpd = CameraUpdateFactory.newCameraPosition(camPos);
  
          mapa.moveCamera(camUpd);
      }
