Integrate Google Maps with SAPUI5 Application

Hi readers!! I was just trying out integrating google maps in ui5 application, so here I am with another tutorial blog. In this blog, I will show you how to create Google developer API key and then how to use it in sap ui5 application to integrate google maps. 

To integrate Google Maps to sapui5 application, you will need  google map API. There are several API available for Google maps itself, like Google Map android API, Google Maps for IOS, Google maps for Street, Google maps Directions API, similarly many more. The one we are going to use is Google Maps JavaScript API.

To use google API, you will need particular developer API key. The google Maps JavaScript APIs will only work with a Browser key. APIs of the same platform can use the same key.
Now before proceeding with sapui5, I will just quickly go through with how to create a developer key and how we will use it in our sapui5 application.
  1. Go to the Google Developers Console.
  2. Create or select a project.
  3. Click Continue to enable the API and any related services.
  4. On the Credentials page, get a Browser key (and set the API Credentials).
Hereby, your API developer key will be created and then you can use it in your application.
To specify a key, include it as the value of a key parameter when loading the API.
For example:
<script async defer src=""
Hope you got the basic idea how to create your API key, now that’s done, lets focus on how to use it in sap ui5 application.
Lets’ make an application, in which we will integrate google maps.

Step 1 Create a new Project in Eclipse, here I am naming it demo_GoogleMaps

Step 2 Now, in the index.html file add the URL containing your API Key. Also add your first page, here I have named it as app.view.xml.
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta http-equiv='Content-Type' content='text/html;charset=UTF-8'/>

<script src="resources/sap-ui-core.js"

var app = new sap.m.App({initialPage:"idapp"});
var page1 = sap.ui.view({id:"idapp", viewName:"",

type ="text/javascript">

.myMap {                   
height: 100%;
width: 100%  ;
<body class="sapUiBody" role="application">
<div id="content"></div>

Step 3 In the app.view.xml file and the following piece of code:
<core:View controllerName=""
xmlns="sap.m" xmlns:core="sap.ui.core" xmlns:mvc="sap.ui.core.mvc"
<App id="appMaps">
<mvc:XMLView id="mainView" viewName="com.googlemaps.view.maps"></mvc:XMLView>

Here I have added new page, and named it as maps.view.xml. In this page I will add the google maps.

Step 4 Now in the maps.view.xml file I am placing a VBox and inside this VBox, I am placing three HBox. In the first HBox, I am placing search field and the distance button and in the second HBox, I am placing the input box for distance calculation. Lastly, in the third HBox I will place the map.

<core:View height="100%" controllerName="com.googlemaps.controller.maps"
xmlns="sap.m" xmlns:core="sap.ui.core" xmlns:mvc="sap.ui.core.mvc"
xmlns:vbm="sap.ui.vbm" xmlns:l="sap.ui.layout"
<Page id="mainPage" enableScrolling="false" title="GMaps">
<VBox fitContainer="true" justifyContent="Center" alignItems="Center">
<HBox fitContainer="true" justifyContent="Center" alignItems="Center">
<Input id="bntSearch" class="controls" type="text" placeholder="Search Box"/>
<Button id ="button" text="search" press="onAfterRendering"/>
<Button id ="Distance" text="Distance" press="onDistancePress"/>
<HBox fitContainer="true" justifyContent="Center" alignItems="Center">
<Input id="FromDis" placeholder="From" visible="false"/>
<Input id="ToDis" placeholder="To" visible="false"/>
<Button id ="Okay" text="Ok" visible="false" press="onOkayPress"/>
<HBox id="map_canvas" fitContainer="true" justifyContent="Center"
alignItems="Center" >


Step 5 We will do most of the coding in maps.controller.js file. I am adding the code here, I will try to explain it step wise through comments.

sap.ui.controller("com.googlemaps.controller.maps", {

onInit: function() {

onAfterRendering: function() {
if (!this.initialized) {
this.initialized = true;
this.geocoder = new google.maps.Geocoder();
window.mapOptions = {                          
center: new google.maps.LatLng(-34.397, 150.644),
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP
//This is basically for setting the initial position of the map, ie. Setting the coordinates, for the place by default

var map = new google.maps.Map(this.getView().byId("map_canvas").getDomRef(),mapOptions);
var infowindow = new google.maps.InfoWindow;
var geocoder = new google.maps.Geocoder();
var marker = new google.maps.Marker({
map: map,

google.maps.event.addListener(map, "click", function (e) {
var lolatitude =; //calculates latitude of the point of click
var lolongitude = e.latLng.lng()//calculates longitude of the point of click"sap.m.MessageToast");"Lat"+lolatitude+"\n Lng"+lolongitude);
var latlng = new google.maps.LatLng("latlng",lolatitude, lolongitude);
var text1 = new sap.m.Text({text:lolatitude});
var text2 = new sap.m.Text({text:lolongitude});
window.point1 = lolatitude;
window.point2 = lolongitude;
geocodeLatLng(geocoder, map, infowindow, text1, text2);

//This function is for what should happen if a user left clicks on the map
function geocodeLatLng(geocoder, map, infowindow,text1,text2) {
var markers = [];
var input1 = text1.mProperties.text;
var input2 = text2.mProperties.text;
var latlng = {lat: parseFloat(input1), lng: parseFloat(input2)};

geocoder.geocode({'location': latlng}, function(results, status) {
if (status === google.maps.GeocoderStatus.OK) {
if (results[1]) {
//Here result will consist of many result, but we have to take fist result //itself, since that would be the appropriate one
function addMarker(location) {
var marker = new google.maps.Marker({
position: location,
map: newmap1
markers.push(marker);// A marker is added to the point where it was clicked
var address1 = results[1].formatted_address;

infowindow.setContent(results[1].formatted_address);, marker);
} else {
window.alert('No results found');
} else {
window.alert('Geocoder failed due to: ' + status);



else if(this.initialized===true){this.actSearch()}


actSearch: function () {
var newmap = new google.maps.Map(this.getView().byId("map_canvas").getDomRef(),mapOptions);
var address = this.getView().byId("bntSearch").getValue();
this.geocoder.geocode({ 'address': address }, function (results, status) {

var marker = new google.maps.Marker({
map: newmap,
position: results[0].geometry.location
//This function is for search. Here when a place is searched a marker is //applied and the map is zoomed to the particular position.

} else {
alert('Geocode was not successful for the following reason: ' + status);
var loFrom = this.getView().byId("FromDis");
var loTo = this.getView().byId("ToDis");
var loOk = this.getView().byId("Okay");
//This function is triggered on click of distance button.

onOkayPress: function(){
//This function calculates approx. distance between the two places, since I //haven’t used Google Maps Distance API, therefore this ain’t the proper way //to calculate distance among the places
var newmap1 = new google.maps.Map(this.getView().byId("map_canvas").getDomRef(),mapOptions);
var address1 = this.getView().byId("FromDis").getValue();
var address2 = this.getView().byId("ToDis").getValue();

} else {
