super.onCreate(savedInstanceState); 
  if (getArguments() != null) {
    mPageFlag = getArguments().getString(ARG_PAGE_FLAG); 
  } 
}

@Override
public void setUserVisibleHint(boolean isVisibleToUser) {
    super.setUserVisibleHint(isVisibleToUser);
    if(isVisibleToUser && !mIsPageLoaded){
        mContext = getActivity();
        mIsPageLoaded = true;
        if(mPageFlag.equalsIgnoreCase(getString(R.string.winners))){
            new getcontestscorewinners(mContext).execute();
        }else{ //

            new getcontestscorewinnersNew(mContext).execute();
        }
    }
}


public class getcontestscorewinners extends AsyncTask<String, Void, String> {
    boolean response = false;

    private Context mContext;

    public getcontestscorewinners(Context context) {
        mContext = context;
    }

    @Override
    protected void onPreExecute() {

        progress = ProgressDialog.show(mContext, "Processing...",
                "Please wait....");
    }

    @Override
    protected String doInBackground(String... params) {

        NetworkTask.getContestScoreWinners(winnerHandler);


        return "";

    }

    @Override
    protected void onPostExecute(String result) {


    }

    @Override
    protected void onProgressUpdate(Void... values) {

    }
}

Let me know if someone can help me for get out of it. Thanks.

`setUserVisibleHint` is in Activity or in Fragment ? and where adding `mPageFlag` to Activity — ρяσѕρєя K, Jan 20 '17 at 05:42
@ρяσѕρєяK is in Fragment and mPageFlag I am adding it on create like public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); if (getArguments() != null) { mPageFlag = getArguments().getString(ARG_PAGE_FLAG); } } — Meera Joshi, Jan 20 '17 at 05:47

Try using isAdded():

Return true if the fragment is currently added to its activity.

So your code should be like this :

if(isAdded() && mPageFlag.equalsIgnoreCase(getString(R.string.winners))){
