THE 5 MISTAKES DEVELOPERS MAKE IN MOVING TO MOBILE


Trying to fit a desktop experience onto a mobile deviceMobile devices lack the facilities of a PC including• large display for easy viewing • a robust in memory cache for fast data process• external keyboard for easy typingDevelopers try to build overly complex capabilities into mobile devices:• cluttering the screen• draining device resources• impacting the end user experience

How to avoid it• identify the high value actions within the app that are most likely to be used

• design only for these requirements• ensure users can complete them with minimum taps• set a maximum tolerance for the no. of steps a user has to take to complete an action

• Learn the most common app types and stick to those, until you are really expert

Mistake #1


Not making the mobile user experience your top priority• With hundreds of thousands of apps your users have lots of choices• If your app is not easy to use people will avoid it• Users don’t not come back after a poor initial user experience

How to avoid it• Focus on a good user experience design• Show users prototypes of the app on actual mobile devices for regular feedback• Ensure users can complete tasks with minimum taps• Ensure that you have satisfied their main requirements before releasing the app

Mistake #2


Mistake # 3Too much get between your app, the OS and the Hardware

• Shave every possible millisecond off response time• Utilize all relevant capabilities offered by the device• A mobile app dev platform that abstracts away device details delivers only the common denominator of functionality across devices

How to avoid it• Build a “True Native App” means your app is optimized for a particular OS• “True Native App” is also optimised for the particular hardware• Skip wrappers like JVMs that abstract away control of fine grained capabilities• Code directly to the device whenever possible


Building separate apps for different platformsBuilding apps with separate codebases for different platforms can lead to multiple issues• Many of your end users own multiple devices• Your app may perform differently on each device• With separate apps features get released and bugs get fixed at different times• Results in out of sync scenario – confusing to users• Managing multiple codebases results in extra development work an higher overhead

How to avoid itSingle codebase that is complied and optimized for different platforms and device form factors• You will deliver a more consistent user experience across all devices• Realise significant savings with fewer resources required for development, QA and delivery

Mistake #4


Mistake # 5Not doubling down on securityRelying on device or network security measures to protect your data can be hazardous• Take active measures to protect data that is resident on the device• Take active measures to protect data passed in communications and service calls• Java, JavaScript and Android are notorious hacker targets

How to avoid it• For key interactions code directly to the device• Include your own security precautions to reduce the risk of third party attacks• Encrypt sensitive data stored on the device

Windows Developer Survey – Dimensional Research

• Overwhelming majority of Windows developers must add mobile to their existing app development strategy– 85% of respondents receive requests for mobile apps– 99% say existing apps must continue to be supported

• Android is the most requested platform among Windows developers– 83% of the requests for mobile app have Android support as a requirement

• HTML5 and JavaScript are not the solution of choice for mobile apps– 85% of respondents say native apps are best for end users– 74% of those who used HTML5 and JavaScript have had challengesDimensional Research (UK) Q3 2013 Survey – 1,337 Windows Developers

Summary

• Most devices (available today) are app ready• Service integrations are standardized on REST/JSON• You (developers) are the center of this Universe and will

be for years to come!
