How can I access getSupportFragmentManager() in a fragment?

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. ``` 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); ```
