Yeah for sure mithun,
function read() {
  if(navigator.onLine){
  alert("hi");
        updateStatus2("read request started");
        startTime = new Date();
        clearTable();
        if (!haveAppId()) {
            return;
        var sURL = applicationContext.applicationEndpointURL + "/DateFormats";
  console.log("Date Formats Fetched"+  sURL);
        var oHeaders = {};
        oHeaders['Authorization'] = authStr;
  oHeaders['X-SMP-APPCID'] = applicationContext.applicationConnectionId;    //this header is provided by the logon plugin
  oHeaders['Content-Type'] = "application/xml";
        oHeaders['X-CSRF-Token'] = "FETCH";
        var request = {
            headers : oHeaders,
            requestUri : sURL,
            method : "GET"
        console.log("read using " + sURL);
        OData.read(request, readSuccessCallback, errorCallback);
  else{
  sap.OData.applyHttpClient();
  //OData.read(request,readSuccessCallback,errorCallback);
    function readSuccessCallback(data, response) {
        var endTime = new Date();
        var duration = (endTime - startTime)/1000;
        updateStatus2("Read " + data.results.length + " records in " + duration + " seconds");
        var productsTable = document.getElementById("ProductsTable");
        for (var i = 0; i < data.results.length; i++) {
            var row = productsTable.insertRow(1);
            var cell1 = row.insertCell(0);
            var cell2 = row.insertCell(1);
            cell1.innerHTML = data.results[i].DateFormatType;
            cell2.innerHTML = data.results[i].DateFormatValue;
the above is my read() function in which the data is read.
I am also attaching my openStore() method:
if (!haveAppId()) {
            return;
        startTime = new Date();
        updateStatus2("store.open called");
        var properties = {
            "name": "DateFormatsOfflineStore",
            "host": applicationContext.registrationContext.serverHost,
            "port": applicationContext.registrationContext.serverPort,
            "https": applicationContext.registrationContext.https,
            "serviceRoot" :  appId,
  "streamParams" : "custom_header=Authorization:Basic " + btoa(applicationContext.registrationContext.user + ":" + applicationContext.registrationContext.password) + ";custom_header=X-SMP-APPCID:" +  applicationContext.applicationConnectionId + ";",
            "definingRequests" : {
                "DateFormats" : "/DateFormats"
        store = sap.OData.createOfflineStore(properties);
  console.log("Offline Store Created");
        //var options = {};
        store.open(openStoreSuccessCallback, errorCallback/*, options*/);
  console.log("Offline Store Opened");
When the device is in online , data is read absolutely fine where as in offline i am unable to read data and Http request failed error is getting displayed.....
