Mobile Apps Development Made Easy

Introduction to Mobile Applications Development

mobile apps development

Mobile application development is building efficient application software for small, wireless computing devices such as smartphones or tablets. Mobile application development often has many challenges because it requires the mobile applications development company to provide solutions for different devices and operating systems, and also for the varied device features their respective screen sizes. Developing mobile applications requires considering the characteristics and constraints of these devices. Mobile devices don´t have as powerful processors as personal computers, they have wide array of screen sizes and more features like camera and location detection. Mobile Application Development Companies also have to consider the diverse hardware specifications and configurations because of intense contention in mobile software and varieties within each of the platforms.

Atlogys is a fast-growth mobile application development company. Our company has specialization in developing mobile applications for iOS (Apple Devices) on iOS 7.x and iOS 8.x and Android 4.x and 5.x for both phones and tablets.

iOS Application Development

iOS application development is the process by which Mobile Application Development Companies create new applications for the family of iOS operating system Devices (iPhone, iPad, iPod) by Apple.

Android application Development

Android application development is the process by which Mobile Application Development Companies create new applications for the Android operating system from Google. Native Android mobile applications are in general developed in the Java programming language using the Android Software Development Kit (SDK), but other mobile development environments are also available in non-native a.k.a Hybrid mode.

As of Jan 2015, more than one million mobile applications have been developed for Android, with over 30 billion downloads. A research suggested that over 67% of mobile developers used the platform.

Today, there are approximately 5 billion people being connected to internet via mobile devices and the popularity of mobile applications has continued to climb, as their utilization has become progressively dominant across mobile phone users. A May 2012 comScore study accounted that during the previous quarter, more mobile subscribers used mobile apps than browsed the web on their devices.

Mobile Application Stores

Mobile Application stores

Mobile Application Developers can project and publish their applications on the various mobile stores, where they get a revenue share on their app selling price. An example is Apple's App Store, which is for iOS mobile apps only. There are more or less 700,000 iOS Applications. Google's Android Market (now known as the "Play Store") has a large number of apps running on devices having Android OS.

Platforms and Tools in Mobile Application Development

There are different ways of developing Mobile Applications and at Atlogys we can make any of the types of mobile apps below:

Platforms and Tools in Mobile Application Development

  1. Native Mobile Applications A native application is created for use on a native platform like mobile and tablets using the native SDk’ which are specific to that platform released by the maker of the platform.
  2. Mobile Web Applications are server-side apps to access website/s on mobile/tablets using different browsers like chrome, Firefox by connecting to a wireless network or mobile network.
  3. Hybrid Mobile Applications are combinations of native app and web app. Hybrid mobile apps run on devices or offline and are written utilizing web technologies like HTML5 and CSS.

Mobile Application Platform and tools permit mobile application developers to write, test and deploy applications into the target platform environment. Each platform is unique and demonstrates different behavior, features and capabilities.

Native iOS Development

The iOS SDK

The iOS SDK formerly iPhone SDK (Software Development Kit) is a software development kit developed by Apple Inc. to develop native mobile applications for the iOS family of products.

The iOS SDK allows mobile application developers to make mobile applications for the iPhone and iPad and provides "iPhone simulator" as well to test them. However, successfully deploying a mobile application onto the devices is only possible after bearing an iOS Developer Program fee, which is $99.00 USD per year. Xcode is the mobile application development environment for the iOS SDK. iPhone/iPad applications, like OS X applications, are written in Objective-C and Swift, with the ability that some elements of the application can also be written in C or C++.

XCode

Majority of mobile applications in Apple’s App Store are written in the Objective-C programming language, and mobile application developers usually use Xcode to develop their mobile applications.

Xcode

Obtaining The Tools

To build an iOS mobile app, you must use Mac OS X and any other operating systems are not supported. The development tools that you’ll require are iOS X SDK and Xcode which are free of charge, and you can run the mobile app that you build in the iOS simulator, which is part of the iOS SDK.

Swift

ios apps programing languageSwift is a new programming language for iOS and OS X mobile apps that builds on C and Objective-C, without the constraints of C compatibility.

Swift’s neat slate, backed by the mature and much-loved Cocoa and Cocoa Touch frameworks follow safe programming patterns and adds advanced features to make mobile application programming simple, flexible, and fun.

Android App Development

Android App Development

Google's Android Developers portal has tons of tools, guides and useful information. The SDK, mobile application development tools and emulators are all accessible for free with tons of examples and tutorials on the site.

Android SDK

The Android SDK (software development kit) includes a comprehensive set of mobile application development tools. These include libraries, a handset emulator, a debugger, sample code, documentation and tutorials. Currently supported development platforms include computers running Linux, Mac, and Windows. Also, Android mobile applications can be developed on Android itself by using specified Android applications.

Cross Operating-system Platforms for mobile app development

Cross-Operating System platforms for mobile apps development on the whole are not yet an entirely perfect solution. Fortunately, there are few really great multi-platform mobile developer tools in the market which can serve us to achieve our objective of writing a mobile app once and having it run on both iOS as well as Android family of devices. Please check below few of the top mobile application development tools for cross-platform mobile applications development that can support demands for both current and future projects.

  1. PhoneGap

    PhoneGap is a mobile application development framework which enables application developers to build applications for mobile devices using HTML5, JavaScript and CSS3. PhoneGap enables wrapping up of HTML, JavaScript and CSS3 depending upon the platform of the device instead relying on platform-specific APIs like those in iOS, Android or Windows Phone. Mixing native and hybrid code snippets has been possible since version 1.9.

  2. Appcelerator

    Appcelerator′s Titanium caters a unified JavaScript API (across devices), coupled with native-platform-specific features. Mobile Application Developers write JavaScript and utilize a UI abstraction that results in the use of native UI components, greatly assisting UI performance compared to other hybrid options.

  3. Adobe AIR

    Adobe AIR is a cross-operating-system runtime that facilitate mobile application developers to combine HTML, JavaScript, Adobe Flash, ActionScript and Flex technologies in deploying rich Internet applications (RIAs) on devices including desktop computers, netbooks, tablets and smartphones.

  4. Sencha

    Sencha Touch is a user interface (UI) JavaScript library, or framework, specifically built for the Mobile Web Applications and fully based on web standards such as HTML5, JavaScript CSS3. Sencha Touch aims to facilitate mobile application developers to rapidly and easily create HTML5 based mobile applications that run on Android, iOS, Windows and BlackBerry devices.

  5. Qt

    Qt ("Cute") is a cross-platform mobile application development tool that targets a number of embedded, mobile and desktop platforms. Mobile Application Developers write code applying QML, touted as a CSS & JavaScript like language and applications are backed with a broad set of C++ libraries, and utilize UI/graphics components written in C++.

Custom Mobile Application

Custom Mobile Application

Custom Mobile Application development is the process of making a mobile application that is particularly developed for a specific organization or user. Since custom mobile application is developed for a single customer it can meet that customer's expectations and preferences. Custom Mobile Application may be designed in staged process, allowing all aspects, risks and dangers to be taken into account, along with all stories from the custom mobile app specifications.

Atlogys team can create almost any type of custom mobile application, from a simple mobile application that displays information about your business, to custom social and Ecommerce functionality including content management, inventory management, customer management (CRM apps), human resource management etc., recruitment, social networking, ePublishing, medical adherence apps, hosting and hospitality industries and verticals.

Mobile applications have earlier provided speedy access to email, contacts, calendar, weather information and stock market. However, public demand and the accessibility of developer tools has forced rapid expansion into other categories and at Atlogys we can cater to your custom mobile app development need for mobile-games, social-media, picture- sharing, location-based services, networking and file transfer, banking, education, video- streaming, order tracking, ticket purchases apps.

Mobile Application Testing

mobile apps testing

Mobile application testing is a process by which mobile applications developed for mobile devices are tested for their usability, functionality and consistency under diverse environments like online/offline mode. Mobile application testing can be automated or manual.

At Atlogys, we have done many kinds of mobile testing and summarizing our experience below:

Major Challenges in Mobile Application Testing

  1. Variety of Mobile Devices - Mobile devices comes in different screen sizes, input methods (touch, normal and QWERTY) with different hardware capabilities. Apple has 3.5 inch, 4inch, 7.9 inch, 9.7 inch and more device types. Android screens are divided into small, normal, large, xlarge with various dpi’s . Android phones have ldpi, mdpi, hdpi, xhdpi, xxhdpi, xxxhdpi. Their screen sizes range from 2 inches to anything till about 10 inches.
  2. Diversity in Mobile Platforms/Operating Systems - Mobile Devices come with various Mobile Operating System, the major ones are Android, IOS, Symbian, Windows and BlackBerry . Each operating system has its own constraints. Testing a single mobile application across multiple devices running on the same platform and every platform poses a unique challenge. Apple for example has iPhone 4, iPhone 4s, iPhone 5, iPhone 5c, iPhone 5s, iPad Air, iPad Air 2, IPad Mini 2, iPad Mini3, iPad Mini, iPad 2, iPad 3. Each of these devices may have any version of iOS 7.x (like 7.0, 7.1, 7.2) or a version of iOS8.x (like 8.1, 8.0.1, 8.0.2). Similarly Android has many different hardware from Samsung, Lenovo, Motorola, micromax, lava, Gionee etc. in the market and software versions include Ice cream sandwich, Jelly bean, Kitkat, LollyPop in different configurations.
  3. Mobile network operators - There are approximately 400 mobile network operators in the world, out of which some are GSM, some CDMA, whereas others use less common network. Each network operator uses a different kind of network infrastructure and this limits the flow of information. Mobile apps may or may not be dependent on an active internet connection. In cases of intermittent network, testing the devices becomes even a harder challenge. Any packet of data being downloaded to a mobile app must resume from where it left off in case of a broken connection.
  4. Scripting- The variety of mobile devices makes executing the test script (Scripting) a key challenge. As mobile devices differ in input methods, keystrokes, menu structure and display properties.

Types of Mobile Application Testing

  1. Functional Testing - Functional testing ensures that the application is working as per the functional requirements. Most of the test carried on for this is driven by the user interface and information flows. We make end to end functional test cases in form of user stories which are also reviewed and approved by the client to ensure 100% acceptance criteria.
  2. Laboratory Testing - Laboratory testing, generally undertaken by mobile network carriers, is done by simulating the complete wireless network. This test is executed to find out any issues when a mobile application uses voice and/or data connection to do some functions.
  3. Performance Testing - Performance testing process is carried out to check the behavior and performance of the application under certain conditions such as bad network coverage, low available memory, low battery, simultaneous access to application’s server by concurrent users and other conditions. Performance of an application can be affected from application’s server side or client’s side and Performance testing is carried out to check both.
  4. Memory Leakage Testing - Memory leakage happens when mobile application is unable to manage the memory it is allocated resulting in poor performance of the application. As mobile devices have substantial constraints of available memory, memory leakage testing is essential for the proper functioning of a mobile application.
  5. Interrupt Testing - A mobile application while functioning may face various interruptions like incoming calls or network coverage outage. The different types of interruptions are:
    • Incoming and Outgoing SMS and MMS
    • Incoming and Outgoing calls
    • Incoming Notifications
    • Media Player on/off
    • Battery Removal
    • Cable Insertion and Removal for data transfer
    • Network outage and recovery
    • Device Power cycle

    A mobile application should be able to address all these interruptions by going into a suspended state and resuming afterwards.

  6. Usability testing - Usability testing is undertaken to affirm if the application is accomplishing its objectives and getting a favorable response from end users. Mobile Application Usability testing is important as the usability of an application is its key to commercial success.
  7. Installation testing - Many mobile applications come pre-installed on the device whereas others have to be installed from the app store. Installation testing verifies that the installation process goes smoothly and covers installation, updating and uninstalling of an application.
  8. Certification Testing - Certification Testing carried out to get a certificate of compliance, each mobile device calls for tested against the guidelines set by different mobile platforms.

Some Mobile Application Testing Tools Atlogys uses

Some Testing tools that are being used to test code quality for mobile applications are as follows:

Cross-Platform (Android and iOS)

For Android

For iPhone

Mobile Application Testing Strategy at Atlogys

The Mobile Application Test strategy should make sure that all the performance and quality guidelines are met. The testing team must have the right devices in the desired software operating systems with the right configurations and sandbox user accounts to test. All 8 *types* of mobile application testing mentioned above must be carried out. A few pointers in this area are:

  1. Selection of the devices - Analyze the mobile device market and choose the devices that are widely used.
  2. Emulators - The use of Emulators is extremely useful in the development stage, as they allow quick and efficient checking of the mobile application. Emulator is a system that runs software from one environment to another without altering the software itself. Types of Mobile Emulators
    • Device Emulator- provided by device manufacturers
    • Browser Emulator- simulates mobile browser environments.
    • Operating systems Emulator- Apple provides emulators for iPhones, Google for Android phones and Microsoft for Windows phones.
