When am lancing camera using

Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
             startActivityForResult(intent, CAMERA_REQUEST);)

And then we getting callback after taking pic to the

                   onActivityResult(){
                   //HERE AM CALL ING ANOTHER FRAGMENT
                  FragmentManager fm = getFragmentManager();
        fm.beginTransaction().replace( R.id.tab_upload, new uploadingActivty(), "tabId").setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN)
        .addToBackStack(null).commit();
                   }

Then we getting error as

                           11-21 16:13:44.316: E/AndroidRuntime(30944): Caused by: java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState

Any idea?
