Beating the Mobile Evolution: Survival of the Technologically Fit

Develop, test, monitor and repeat is key

The exponential growth of smartphone users around the globe is no secret. IDC's Worldwide Quarterly Mobile Phone Tracker reports that vendors shipped a total of 444.5 million mobile phones in 3Q12 alone. The importance of the mobile evolution reaches a broad range of industries from financial services to travel and hospitality. Integrating mobile strategies includes meeting the needs of the mobile generation and is a crucial element for any business to grow and sustain.

The burden of creating great consumer experiences and high quality enterprise applications across multiple platforms, including iOS, Android, and Windows, sits on the shoulders of mobile Web and app developers worldwide.

While the perception of an iPhone world may be grandiose, the reality is iPhone and iOS only contribute to a small percentage (18 percent according to IDC's 2011 research) of the total global smartphone usage. Most mobile Web and App developers aware of the fragmented mobile market understand the headaches when faced with the daunting task of having to create for multiple platforms in order to capitalize on the 81 percent that are not iOS users. Even though Android has recently emerged as the popular platform leader, there are still numerous feature and smartphone devices that also need to be considered during development.

When it's all said and done, the judgment of quality rests in the hands of the end user. Most companies do not have the resources or second-chance opportunities to release a product without proper testing on multiple platforms. The caveat for developers working in the mobile space relies on the ability to test on multiple devices, which means having access to hundreds of devices, not generally the case. The current trend is shifting to testing on the cloud with emulated software, avoiding the need to make space for multiple devices in the development laboratory and alleviating the need to expend an exorbitant amount of resources to find, purchase and ship hundreds of mobile devices just for testing purposes.

Mobile Landscape

The fragmented mobile landscape has also been a pain point on the enterprise level. The growing adoption of BYOD has presented the need to push out quality-assured applications on a multitude of devices. This trend has increased the need to use effective testing tools that can speed up development time and push out products to keep up with the push toward mobile, where devices and their platforms are frequently updated. Enterprise customers need to be able to deploy effective communication to their employees and create mobile apps and tools that will ultimately increase productivity, and real-device testing is an efficient way for the enterprise to stay ahead of user issues.

    In mobile development there are some common mistakes during testing process that are critical to the end product.

  1. Not testing apps based on different device screen sizes. Don't trust that just because an app looks okay on one device, it will look fine on other platforms. Platforms vary in the slightest ways and can change the entire experience or perhaps not function as intended in some areas. You should test apps based on actual screen size and device types.
  2. Assuming that performance issues are consistent across all devices. Make sure to look for device-specific problems. Usually, if you can reproduce a bug or glitch using a desktop browser, the issue is likely not device-specific. However, if a bug shows up on one device and not another, realize that you need to figure out which device and platform the bug is affecting.
  3. Neglecting use and idle tests. Run through use and idle tests. Fully charge the device and do one of each type of test, for example:

Use-test: Use the application on a fully charged device for a number of hours. Take battery life and other readings at regular intervals. Set automated scripts to run and test the application for up to 12 hours to determine how many resources your application uses while it is being accessed.

Idle test: Turn on the application while the device has a full battery, and leave it running on its home or menu screen for up to 12 hours. Record battery and resources usage at regular intervals in order to determine if the idle application is using additional resources behind the scenes.

HTML5: The Ultimate Solution?
The big nudge in the HTML surge was pushed further as Steve Job addressed his aptly named "Thoughts on Flash" public note in 2010. The search for simple has sparked complexity though. Developers have been toying with the idea of hybrid apps; web apps wrapped as native apps. LinkedIn is a good example of a native app providing an embedded web view.

The introduction of HTML5 has been a great advancement in the development community and helps to streamline cross-platform coding. Simplified and minimalist is the key for success in today's on-the-go mobile culture. The "write once, run anywhere'" method has been a strong wish for developers for decades; HTML5 has not solved the issue but brought us much closer. The debate between native, hybrid and HTML5 applications is not likely to be resolved in the near future. In order to untie the complex shoelace, it's imperative for developers to consider which approach best suits their application and end-user requirements.

Nevertheless, testing remains a critical component of speed and efficiency in the development process; advances in automated testing solutions make testing hundreds lines of code efficient and consistent.

The Mobile Bottom Line
The mobile development cycle has increased in demand and become more complex and engulfing to our everyday lives. Developer pain points may never disappear but leveraging tools that will enable speed and efficiency are critical to implement in any development cycle. Will there be a single, solve all, end-all solution to cross-platform development issues? While HTML5 addresses the case, the answer will probably be no. As the demand for mobile devices continues to grow, so will usage and the need for new development and maintenance. Now that smartphones are becoming integrated into our daily habits, the next phase (which has already begun) is using a single device to align all areas of our lives: home, work and leisure. The way to stay quick and nimble with the growing demands of mobile development is to create an efficient process. Develop, test, monitor and repeat is key!

Software development, like manufacturing, is a craft that requires the application of creative approaches to solve problems given a wide range of constraints. However, while engineering design may be craftwork, the production of most designed objects relies on a standardized and automated manufacturing process. By contrast, much of moving an application from prototype to production and, indeed, maintaining the application through its lifecycle has often remained craftwork. In his session at Dev...
How can you compare one technology or tool to its competitors? Usually, there is no objective comparison available. So how do you know which is better? Eclipse or IntelliJ IDEA? Java EE or Spring? C# or Java? All you can usually find is a holy war and biased comparisons on vendor sites. But luckily, sometimes, you can find a fair comparison. How does this come to be? By having it co-authored by the stakeholders. The binary repository comparison matrix is one of those rare resources. It is edite...

With the advent of micro-services, the application design paradigm has undergone a major shift. The days of developing monolithic applications are over. We are bringing in the principles (read SOA) hereto the preserve of applications or system integration space into the application development world. Since the micro-services are consumed within the application, the need of ESB is not there. There is no message transformation or mediations required. But service discovery and load balancing of ...
There’s a lot of discussion around managing outages in production via the likes of DevOps principles and the corresponding software development lifecycles that does enable higher quality output from development, however, one cannot lay all blame for “bugs” and failures at the feet of those responsible for coding and development. As developers incorporate features and benefits of these paradigm shift, there is a learning curve and a point of not-knowing-what-is-not-known. Sometimes, the only way ...
The Internet of Things is a misnomer. That implies that everything is on the Internet, and that simply should not be - especially for things that are blurring the line between medical devices that stimulate like a pacemaker and quantified self-sensors like a pedometer or pulse tracker. The mesh of things that we manage must be segmented into zones of trust for sensing data, transmitting data, receiving command and control administrative changes, and peer-to-peer mesh messaging. In his session a...

This article shows you how use the xebialabs/xldeploy Puppet module. The Production environment is based on 2 tomcats instances (tomcat1 &...
Do you think development teams really update those BMC Remedy tickets with all the changes contained in a release? They don't. Most of them just "check the box" and move on. They rose a Risk Level that won't raise questions from the Change Control managers and they work around the checks and balances. The alternative is to stop and wait for a department that still thinks releases are rare events. When a release happens every day there's just not enough time for people to attend CAB meeting...
There is no doubt that Big Data is here and getting bigger every day. Building a Big Data infrastructure today is no easy task.

There is no question that the cloud is where businesses want to host data. Until recently hypervisor virtualization was the most widely used method in cloud computing. Recently virtual containers have been gaining in popularity, and for good reason. In the debate between virtual machines and containers, the latter have been seen as the new kid on the block – and like other emerging technology have had some initial shortcomings. However, the container space has evolved drastically since coming on...

Data-intensive companies that strive to gain insights from data using Big Data analytics tools can gain tremendous competitive advantage by deploying data-centric storage. Organizations generate large volumes of data, the vast majority of which is unstructured. As the volume and velocity of this unstructured data increases, the costs, risks and usability challenges associated with managing the unstructured data (regardless of file type, size or device) increases simultaneously, including end-to-...
I’m not going to explain the basics of microservices, as that’s that’s handled elsewhere. The pattern of using APIs, initially built to cross application boundaries within a single enterprise or organization, is now being leveraged within a single application architecture to deliver functionality. Microservices adoption is being driven by two forces: the need for agility and speed; and the re-composing of applications enabling experimentation and demands to support new delivery platforms such as...
