GlueCon'11 - Native vs Wrapped Mobile apps : What to Build ?
- 1. NATIVE vs WRAPPED APPSWhat to build ? Guilhem Ensuque Twitter: @gensuque_op Hashtags: #openplug, #gluecon Slides: http://slideshare.net/gensuque
- 2. Typical app story – episode 1 Boss: “I need an iPhone app !” Engineer: “OK I go learn Objective-C and do it …” Engineer (3 months later) : “Done !”
- 3. Boss: “Ah but… how about Android ?” Engineer: “I need to learn Java !” Boss: “I don’t have the money nor the time for that!” Typical app story – episode 2
- 4. LESSONS LEARNED Your mileage may vary User Experience Resources Platforms
- 5. USER EXPERIENCE Tailored vs Generic ? How does the user get my app ? How much integration ?
- 6. USER EXPERIENCECASE IN POINT: FACEBOOK iPhone app iPad website
- 7. PLATFORMS Which to target ? Tablets, TVs, cars, fridges ? Smartphone vs feature phone ?
- 8. PLATFORMSA BIT OF HISTORY Source: Asymco blog
- 9. PLATFORMSWHERE IT'S GOING Microsoft WM6.x/WP7 Nokia Symbian RIM Blackberry Apple iOS Android Worldwide Mobile OS Marketshare 2011 (source: Gartner)
- 10. RESOURCES Time vs Money? What are my team skills ? Do we have legacy code ?
- 11. RESOURCESSOCRATIC APPROACH “γνῶθι σεαυτόν “ “Know Thyself”
- 12. TECHNICAL SOLUTIONSNO SILVER BULLET NATIVE WEB X-PLATFORM WRAPPED WORE
- 13. WRITE ONCE RUN EVERYWHERE#FAIL User Experience Not Good So-so Resources Platforms Good
- 14. WRAPPED WEB APPS#GOOD User Experience So-so Resources Platforms Good Good
- 15. CROSS-PLATFORM NATIVE APPS#FTW User Experience Good Resources Platforms Good So-so
- 16. NATIVE APPS#EXPENSIVE User Experience Good Not Good Not Good Resources Platforms
- 17. HYBRID APPROACHANATOMY OF AN HYBRID WRAPPED/NATIVE APP Native stacks & middleware UI + core app logic Network APIs and generic libs
- 18. CONCLUSION Use the right tool for the right job
- 19. A bit of self-advertising http://developer.openplug.com
Editor's Notes
- Show of hands How many of you have developed a mobile app ? Who has developed for iPhone ? Who has developed for Android ? other platform ?
- Tradeoff to be made between Resources (team available, money, time, skills, legacy code) Platforms (fragmentation, mobile vs tablet vs TV vs other, smartphonevs feature phone …) User Experience (tailored vs platform/context-specific, ease of distribution, integration with system …)
- Good user experience drives engagement “Uncanny valley” effect : app UX has to be integrated with rest of the system, there’s no “close enough” integration, users will tell Distribution: app store vs web, issues of searchability, discoverability, monetisation
- iPhone: native app with “close enough” to native UX, still feel disturbed as a useriPad: just a website, no app … very “uncanny”. Users expect gestures, photo gallery integration
- Tradeoff to be made between Resources (team available, money, time, skills, legacy code) Platforms (fragmentation, mobile vs tablet vs TV vs other, smartphonevs feature phone …) User Experience (tailored vs platform/context-specific, ease of distribution, integration with system …)
- Good resources to check:Asymco (Horace Dediu)Communities Dominate Brands (TomiAhonen)Analyst houses (Gartner, IDC, Forrester …)
- Symbian still #1 worldwide, but major regional differences, Nokia announced its end of life after 150m units -> 2012 Android explosion but fragmentation due to OEM and operator variants + non-smartphone devices: tablets, TVs, embedded systems …iOShodling steady, Apple does not care about market share but about profits (with 5% market share of all devices they make up 35% of profit) RIM declining, trying to reinvent themselves with TAT acquisition, QNX, Playbook, HTML5, Android apps on BB -> looks like Nokia 3 years ago WP7: nice and cool, but low penetration, will Nokia help ?
- Tradeoff to be made between Resources (team available, money, time, skills, legacy code) Platforms (fragmentation, mobile vs tablet vs TV vs other, smartphonevs feature phone …) User Experience (tailored vs platform/context-specific, ease of distribution, integration with system …)
- Skills: C/C++/Obj-C, OpenGL, Java, J2ME, Android Java, Blackberry Java, Flash Lite, Flash, AIR, Silverlight/.NET/C#, Lua, Ruby, Javascript, HTML5/CSS3 Code reuse Tradeoff between time and money “GnotiSeoton” : Know Yourself – ask yourself the right questions, no single right or wrong answers
- Wide spectrum of options Web site- “Write-once-run-everywhere” app: web app, Flash/AIR, Java/J2ME, Silverlight Wrapped web app: HTML5 + Sencha/jQueryMobile + PhoneGap/Apparat.io; BrightcoveAppCloud ?, RIM WebWorks, Nokia WRT, WAC Cross-platform native app: OpenPlug, Appcelerator, MonoTouch Native app: iOS SDK/xCode, Android SDK, BB SDK, Nokia S60 Carbide SDK
- Technologies: Java, Flash/AIR, SilverlightAdvantages:Single devSame user experience on all devicesDrawbacks:Poor performanceUI not consistent with rest of platform“Uncanny Valley” effectCannot be distributed on all platforms/app stores (notably Apple)
- Technologies: HTML5/CSS3, Frameworks:Sencha/jQuery Mobile, native extensions: PhoneGap, packaging: PhoneGap, Apparat.ioAdvantages:Single code baseUser experience tailoredCan be distributed on all platforms/app stores (notably Apple)Drawbacks:Performance so-so, getting better with faster JS enginesUI closeness dependent on selected framework, not quite there ?
- Technologies: Alcatel-Lucent OpenPlug, Appcelerator Titanium , Novell MonoTouchAdvantages:Single code base / dev skill setUser experience adapted to platformVery good performanceDistribution through app storesDrawbacks:None ?Depends on your socratic answers
