• Possible Roadmap items

• In-app purchasing (Qt Purchasing)

• Adopting to Windows 10


Use Cases

Let’s Look at a Larger Picture of What Does This Actually Enable!


Cross-Platform Mobile Consumer Apps

• Natural, obvious target for Qt developers

• Target the whole market

• Android, iOS, Windows Store

• Phones and tablets

• Future-proof

• Indie Mobile licensing


Qt is Not Just Mobile


Enterprise Mobility

• Go Mobile with your existing Qt (or non-Qt!) application

• Share code between desktop, embedded and mobile clients

• Write a native mobile client for your enterprise backend system


Extending Qt Desktop App into Mobile

• Your code will run there

• Qt Widgets can be used, but not really recommended for mobile

• Different user experiences on desktop than on mobile -> Different UI layouts anyway

Migrating to Qt Quick

• Qt Quick Controls

• Regular + Enterprise

• Native LAF (5.4 adds Android!)

• Easy customization

• Mix and Match

• QQuickWidget

• QOpenGLWidget

”BYOD”


Internet of Things


Use Cases for IoT

• Control any device remotely using a mobile device or tablet: Consumer Electronics, Automotive, Point-of-Sales, Industry Automation (BYOD, Bring Your Own Device)

• Smart wall thermostats

• Home appliances

• TVs, Set-top-boxes

• Auxiliary (mobile) screens for service or for completely headless devices

• Smart, connected sensors/sensor clusters with Cloud connection and server-side computation and remote adjusting: Industry automation

• Mobile Health (mHealth)

• Mash-Ups of global device networks, for smart applications, such as traffic control, logistics

• Remote monitoring and controlling of global manufacturing chains, improved inventory and stock management

How About Software Developers?

Why isn’t anyone thinking about the software developers?


Success Factors for IoT Software Vendors

• Managing the communication with connected devices/sensors;

• Providing middleware for integration to data repositories;

• Storing and securing the data; and

• Analyzing and visualizing the data

Goldman Sachs report: IoT primer, The Internet of Things: Making sense on the next mega-trend


Problems for Creating an IoT System—from Software Perspective

• Creating an embedded device. Still as painful as always.

• Boot to Qt, Embedded tooling, Qt Creator

• Creating an extendable architecture for a system of embedded devices

• Future-prooving software with Qt, platform independency

• Creating a back-end for the embedded devices to hook into (OK, ”The Internet” IS already there)

• Qt Cloud Services

• Making the devices and the backend data somehow reachable to all consumers

• Cross-Platform Software Framework

• Big Data

• Cloud computing, Data analysis and visualization libraries, Preparing the existing framework parts

Getting Started

So how do I then take my software into mobile?


Tooling Setup – Android


Tooling Setup – iOS

• Xcode and Xcode command line tools are enough

• Apple developer id

• Register your device

• Developer/distribution provisioning profile

• Associates together device id, application bundle id, and developer certificate

• Developer/distribution certificate


Deployment and Publishing

• Three deployment options in Android

• Projects > Run > Deploy configurations

• Publishing in Google Play

• Signed APK can be created in QtCreator

• Login to Goole Play and upload your app

• iOS

• CtCreator plugin creates Xcode project too

• Open the project in Xcode and set version number, icons, orientation etc.

• Publish using iTunes Connect


Windows Phone Pre-Reqs

• Visual Studio 2013

• Windows 8.1

• Tools have been mostly integrated into Qt Creator, but visual Studio is needed for debugging on phone

• Submitting to Windows Store

• The web interface takes the package created by Visual Studio (or Qt Creator)
