      private static int RESULT_LOAD_IMG = 1;
      @Nullable
      @Override
      public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
  
          View rootview = inflater.inflate(R.layout.share, container, false);
          home_page = (Button) rootview.findViewById(R.id.home_page);
