Gaming Industry – The money-making world for young entrepreneurs There are many stories on App Developers becoming billionaires at a very young age. What you need to make a great App? - A unique idea - Little or no investment - A few hours What you get? - A global market of over 250 million smartphone and tablet users - A share in 33,675 downloads a minute or 17.7 billion a year Why games? Mobile games is the most popular App Category - 7080% downloads are games 93% of app downloaders who pay for an app, pay for a mobile gaming app The smartphone gaming industry is expected to double by 2016

Why to start with Android Biggest smartphone market • 48.5% share alone • Android platform has been adapted by all the big mobile hardware vendors - Samsung, HTC, Motorola etc. You can develop for Android from multiple devices - Windows, Mac OS and Linux unlike iOS where you require a Mac Android is an OS based on the Linux Kernel – an open source • Java is the programming language - a very old language, with large number of tutorials and content available Simpler publishing process • Cheap developer fee on the Play Store ($25 one-time), as opposed to $99 per year for Apple Store • Easy and quicker updating of apps With the integration of Google Wallet and Google Checkout, monetization has become easier

Prerequisites for the workshop Downloaded Java and configured the Path You must have Downloaded Eclipse and Android SDK Registered with ShepHertz to access App42 Android SDK

Steps to create a Mobile App A great imagination leads to a great App The App must provide some kind of benefit to the users, be it tangible like saving their time, reducing costs, enhancing productivity or intangible, like giving them a good experience. To create a successful mobile app: • Identify a problem which can be resolved by your App • Decide on the must-have features If you are making a Game: • It must have a unique game-play and • must provide a great user-experience

Contd.. Planning and Identifying Planning is the most crucial phase of any IT project. For a Mobile App, you need to first identify: • The Target Audience Everything should be planned and developed keeping in mind the target users. This will surely increase the probability of success • Mobile Platforms and Devices to be supported Platforms and devices should be selected keeping in mind their geo-coverage among your target users, device support, performance and compatibility with your App. • Revenue model The App market is booming like never before. To generate revenue from this umpteen resource, you need to select the appropriate approach in accordance with your app. There are different models of generating revenue - paid Apps, in-app freemium, advertisements, subscription and pay per download. You should have a clear monetization strategy, right from the beginning.

Contd.. Designing A great design is yet another significant factor responsible for the success of your App. You must concentrate on the UI design and multi-touch gestures for your App and consider platform design standards as well. Today, a lot of emphasis is on the UI design and graphics of an App. If a user does not find the App visually appealing in the first look, he is bound to delete the App as there are multiple options available in the market. A great design creates an instant impact on the mind of the user while ensuring usability of the App. Design tools for a basic App: • Xcode / Eclipse • Image Editing tool (Adobe Photoshop)

Contd.. Identify approach to develop - native, web or hybrid App development Approach must be in accordance with your time and budget constraints. • Native Native Apps deliver the best user experience but require significant time and skill to be developed. These Apps are basically platform specific and require expertise along with knowledge • Web Web Apps are quick and cheap ones to develop and can run on multiple platforms but are less powerful than Native Apps. These are developed using HTML5, CSS or JavaScript code • Hybrid This recent approach combines prebuilt native containers with on-the-fly web coding in order to achieve the best of both worlds. In this approach, the developer augments the web code with native language to create unique features and access native APIs

Contd.. Develop a prototype • The process of taking your idea and turning it into an application with some basic functionality • A prototype makes it easier to sell your idea to potential buyers who can now actually view the tangible benefits instead of just visualizing or reading product description. It is quite helpful in attracting investors and finding licensees

Contd.. Application Programming iOS Applications • IDE: Xcode • Language: Objective C Android Applications • IDE: Eclipse • Language: Java Windows Applications • IDE: Visual Studio • Language: C, C++, C# Blackberry Applications • IDE: Eclipse • Language: Java, C++

Contd.. Testing Functional Testing Functional testing ensures that the application is working as per requirements Performance Testing This testing process is undertaken to check the performance and behavior of the application under certain conditions such as low battery, bad network coverage, low available memory, and simultaneous access to application‟s server by several users and other conditions. Performance of an application can be affected from two sides: server side and client side

Contd.. Memory Leakage Testing Memory leakage happens when an App is unable to manage the memory it is allocated resulting in poor performance of the App and overall slowdown of the system. As mobile devices have limited memory, memory leakage testing is very crucial. In case of Android, Memory Management is automatically done by Android System Interrupt Testing There are different types of interruptions: Incoming and Outgoing calls, SMS, MMS, Incoming Notifications, Battery Removal, Cable Insertion and Removal for data transfer, Network outage and recovery, Media Player on/off You need to check if the App is able to handle interruptions by going into a suspended state and resuming afterwards.

Contd.. Usability testing Usability testing is carried out to verify if the application is achieving its goals and getting a favorable response from users. This is important as the usability of an application is its key to commercial success. This can be done by beta-testing the App within a group of users Installation testing Installation testing verifies that the installation process goes smoothly without the user having to face any difficulty. This testing process covers installation, updating and uninstalling of an application. Certification Testing To get a certificate of compliance, the App needs to be tested on each mobile device against the guidelines set by different mobile platforms.

Contd.. Deploying and Releasing Deployment Management includes planning, scheduling and controlling the expected traffic on the App. Buying server space in advance is a costly affair. So these days a number of PaaS (Platform-as-aService) providers have come up in the market to provide shared server space to developers to reduce their cost on infrastructure. Publishing on Store The Publishing process is more or less similar on every store. Guidelines to publish on the Play Store will be taken up in V.02 next Wednesday.
