        }

        return super.onOptionsItemSelected(item);
    }

    /**

     */
    public static class DetailFragment extends Fragment {


        private static final String LOG_TAG = DetailFragment.class.getSimpleName();
        private static final String FORECAST_SHARE_HASHTAG = " #SunshineApp";
        private String mForecastStr;

        public DetailFragment() {
            setHasOptionsMenu(true);
        }

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            Intent intent = getActivity().getIntent();


            View rootView = inflater.inflate(R.layout.fragment_detail, container, false);

            if (intent != null && intent.hasExtra(Intent.EXTRA_TEXT)) {
                mForecastStr = intent.getStringExtra(Intent.EXTRA_TEXT);
                ((TextView) rootView.findViewById(R.id.detail_text)).setText(mForecastStr);
            }
            return rootView;
        }


        private Intent createShareForecastIntent() {
            Intent shareIntent = new Intent(Intent.ACTION_SEND);
            shareIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
            shareIntent.setType("text/plain");
            shareIntent.putExtra(Intent.EXTRA_TEXT, mForecastStr + FORECAST_SHARE_HASHTAG);
            return shareIntent;
        }
    }
}

In the code above when the line in the onCreateOptionsMenu where I use LOG_TAG and where I use createShareForecastIntent says cannot resolve symbol and method. I tried googling it but couldn't find anything. I am new to android and java both.

Declare createShareForecastIntent as static since FORECAST_SHARE_HASHTAG is static. if you want to use them inside a non-static class method, you can either declare it public and call it like this: DetailFragment.FORECAST_SHARE_HASHTAG, or simply declare the method that's using it without class reference as static.

i.e.:

public static final String FORECAST_SHARE_HASHTAG = " #SunshineApp";


// call it like this, referencing the class name
shareIntent.putExtra(Intent.EXTRA_TEXT, mForecastStr + DetailFragment.FORECAST_SHARE_HASHTAG);

You need to define LOG_TAG in your DetailActivity first as such:

private static final String LOG_TAG = "Some tag string";

I want to use members of the nested class and not from the main class. That is the entire point of the question. – Akash Garg Dec 25 '15 at 17:36
Then change your LOG_TAG to public static final String LOG_TAG = DetailFragment.class.getSimpleName(); – Grace Coder Dec 26 '15 at 02:38
