How to use Hybrid Application Toolkit (HAT) and test the apps

[former_member125464]

Introduction

In this blog we are going to see how to use the Hybrid Application Toolkit for SAP Web IDE and how to mobilise and test the app generated with the development environment.

This blog has been split in 3 parts:

Link	Content
Part1 (this page)	Introduction and some preliminary steps
Part2	Preview apps on the emulator and on the device (iOS and Android)
Part3	Run apps on the emulator and on the device (iOS and Android)

What is Hybrid Application Toolkit (HAT)

SAP Web IDE Hybrid App Toolkit Add-on enables developers to create and deploy Apache Cordova hybrid apps.

The Hybrid App Toolkit includes 3 components:

1) SAP Web IDE plugin which adds hybrid app development features to SAP Web IDE. These features include:

• auto code completion and documentation for Cordova and Kapsel plugin APIs
• hybrid project templates and code snippets
• device configuration
• previews on Companion app, and browsers
• deploy to local, HANA Cloud, and SAP Mobile Platform environments
• deploy and run app on target device

This plugin is currently available as an optional plugin for SAP Web IDE. This means that it's shipped with SAP Web IDE, you just need to enable it from the Optional Plugins section

2) Hybrid App Toolkit Connector which is a local server process that enables SAP Web IDE to connect to the local system's Cordova development environment and allows developers to create and manage a local Cordova project.

3) Companion application which is a native mobile application that runs on a mobile device or device emulator and enables a live preview of a Web application created with SAP Web IDE. It's included in the Hybrid App Toolkit package

How to get HAT

Hybrid Application Toolkit can be downloaded here directly from the SAP Store

How to install HAT

The installation guide for Hybrid Application Toolkit can be found here.

Beside this you can find a complete walkthrough for the installation on the Windows platform in this blog.

How to use HAT

There are many different ways to use HAT and in this blog we are going to see some of them. The steps listed here are pretty the same for Android and iOS platforms so I'm going to put side-by-side the screenshots for both platforms just for sake of comparison.

What is the main goal of this blog

The main goal of this blog is to show you how to

• develop a simple SAPUI5 Master-Detail application from one of the standard templates, in SAP Web IDE. This app takes data from a SAP HANA Cloud destination, which we are going to define, pointing to the service http://sapes1.sapdevcenter.com:8080/sap/opu/odata/IWBEP/GWDEMO for getting the Sales Order Products information
• add some custom code to this app to extend the search bar functionality:
  • add a new button next to the search field of Master View to scan the product barcode
  • search for its information in the backend. For this the Kapsel Barcode Scanner Plugin will be used
• when the app is ready, mobilise it using the Hybrid Application Toolkit and the trial HCPms system
• test it using various methods like,
  • Test as a Web app
  • Run with Cordova Façade in the browser
  • Preview with Companion App on
    • Emulator
    • Android Device
  • Run on
    • Emulator
    • Device
  • Deploy to HCPms and then on Device

Preliminary steps

• Check the prerequisites
• Setup the required destination
• Enable HAT plugin in SAP Web IDE and check its connectivity
• Create a new app in the HCPms administration console
• Create a QR-Code of a product
• Create an hybrid application with SAP Web IDE

Check the prerequisites

Ensure all the prerequisites are met.

• SAP Web IDE (Register at SAP HANA Cloud Platform to get the development environment)
• Hybrid Application Toolkit downloadable from here
• An HCPms account configurable as described here
• Valid user for ES1. Procedure to get access information is described here
• An Android/iOS device to test the application. To connect an Android device to the PC to test your applications you need to install the appropriate USB driver. Follow this link for the detailed steps.

Note: A mobile device simulator can be used only to add contacts, but for Barcode Scanning a real Mobile device is needed. For using the Device Emulators and for other installation prerequisites regarding SAP Web IDE Hybrid App Toolkit Add-on please refer to the SAP Web IDE Hybrid App Toolkit Add-on | SCN.

9) Paste the following code just after the closing of the "contentMiddle" tag and save the file

<contentRight>

  <Button id="barcodebutton" icon="sap-icon://bar-code" press="onBarcodeScan"></Button>

</contentRight>

10) Open the Master.controller.js file, paste the following code just after the "onInit" function and save the file

  onBarcodeScan: function() {

  var that = this;

  var code = "";

  if (!cordova.plugins.barcodeScanner) {

  alert("Barcode scanning not supported");

  return;

  }

  cordova.plugins.barcodeScanner.scan(

  function(result) {

  code = result.text;

  that.getView().byId("searchField").setValue(code);

  that.onSearch();

  },

  function(error) {

  alert("Scan failed: " + error);

  }

  );

  },

11) Right click on the name of the project and choose Project Settings

12) Click on Device Configuration and set the parameters in the following way

Parameter	Value
App Name	Products
App ID	com.test.products

HCPms/SMP	HCPms
HCPms Host	hcpms-<your_account>.hanatrial.ondemand.com (where <your_account> is the one you got on the Trial Landscape

NOTE 1: pay attention that the App ID here must match the Application ID you defined at step 4 of the chapter "Create a new app in the HCPms administration console", otherwise the application will be not working

NOTE 2: regarding the Platform parameter, you have to choose the platform you are going to test your app for. If you have a Windows machine you can only use Android as deployment platform. If you have a Mac, instead, you can use both platform for testing and running mobile applications. In my case, since I'm using a Mac and I want to show you the differences between the two platforms I'm going to select both!

13) Congratulations! You have created your hybrid application. This is the app we are going to use for our tests in this exercise.

This blog now will continue with a second part where you will learn about all the different ways to test and run an hybrid application with HAT.
