Fetching Data in Google SpreadSheets

Question

I have a problem with this reference From this Site Using Google SpreadSheet as Database. the problem is that. the Android Application cannot fetch the data in a google spreadsheet. The Application can successfully run but couldn't find data in the Spreadsheet.

I Already Updated the codes from the android studio because of the old version used codes. I just copy and paste it and change some of it.

Codes Below:

The Script Link to fetch the Data :

https://script.google.com/macros/s/AKfycbwZJCWoQ7dpC5KwyRM9JYsjCjymQUspAfPmniOApD_CSEoc-LdP/exec?id=16O_OfgKxASgqa2WWQKePJI1jnJMTdb4OyXbUJU6kWH0&sheet=Sheet1

Link of the SpreadSheet :

https://docs.google.com/spreadsheets/d/16O_OfgKxASgqa2WWQKePJI1jnJMTdb4OyXbUJU6kWH0/edit#gid=0

This is the App Script that Fetches the data:

you can also see the app script codes here : App Script Codes.

    function doGet(request) {
  var output  = ContentService.createTextOutput(),
      data    = {},
      id      = request.parameters.id,
      sheet   = request.parameters.sheet,
      ss      = SpreadsheetApp.openById(id);

  data.records = readData_(ss, sheet);

  var callback = request.parameters.callback;

  if (callback === undefined) {
    output.setContent(JSON.stringify(data));
  } else {
    output.setContent(callback + "(" + JSON.stringify(data) + ")");
  }
  output.setMimeType(ContentService.MimeType.JSON);

  return output;
}


function readData_(ss, sheetname, properties) {

  if (typeof properties == "undefined") {
    properties = getHeaderRow_(ss, sheetname);
    properties = properties.map(function(p) { return p.replace(/\s+/g, '_'); });
  }

  var rows = getDataRows_(ss, sheetname),
      data = [];

  for (var r = 0, l = rows.length; r < l; r++) {
    var row     = rows[r],
        record  = {};

    for (var p in properties) {
      record[properties[p]] = row[p];
    }

    data.push(record);

  }
  return data;
}


function getDataRows_(ss, sheetname) {
  var sh = ss.getSheetByName(sheetname);

  return sh.getRange(2, 1, sh.getLastRow() - 1, sh.getLastColumn()).getValues();
}


function getHeaderRow_(ss, sheetname) {
  var sh = ss.getSheetByName(sheetname);

  return sh.getRange(1, 1, 1, sh.getLastColumn()).getValues()[0];  
}
