title: How can I access getSupportFragmentManager() in a fragment?
body: <p>I have a FragmentActivity and I want to use a map fragment within it.  I'm having a problem getting the support fragment manager to access it.</p>
  
  <pre><code> if (googleMap == null) {
              googleMap = ((SupportMapFragment) getSupportFragmentManager()
                      .findFragmentById(R.id.map1)).getMap();
  
              // check if map is created successfully or not
              if (googleMap == null) {
                  Toast.makeText(getApplicationContext(),
                          "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                          .show();
              }
          }
  
              // create marker
              MarkerOptions marker = new MarkerOptions().position(
                      new LatLng(latitude, longitude)).title("Hello Maps ");
  
              CameraPosition cameraPosition = new CameraPosition.Builder()
                      .target(new LatLng(latitude, longitude)).zoom(15).build();
  
              googleMap.animateCamera(CameraUpdateFactory
                      .newCameraPosition(cameraPosition));
  
              // adding marker
              googleMap.addMarker(marker);
  </code></pre>
