10. Benefits of native development
• Default OS look & feel (UI conventions)
• Performance
• Access to device hardware (GPS, etc)
• App store/marketplace distribution
• Benefit from latest OS enhancements
11. Drawbacks of native development
• Tied to the particular OS you built for
• Maintaining a multi OS team/skill-set
• Dealing with the app store approval
process
• Keeping app in sync with OS updates
12. Benefits of hybrid development
• Common codebase for multiple OS's
• Access to device hardware (GPS, etc)
• App store/marketplace distribution
• Skills you already have (HTML, CSS, JS)
• Potential code reuse in web site/app
13. Drawbacks of hybrid development
• Build for lowest common denominator
• 3rd party SDK's might lag behind OS
– Want to use feature X? Wait for an
implementation in abstraction layer
• An abstraction layer can have bugs of
its own. Have to determine if a bug is in
your code, the abstraction layer, or OS.
14. So, what should I build?
• Desktop web app
• Mobile web app
• Mobile native app
16. Webview and the mobile web…
• Webviews and Mobile web are
almost the same…
17. Webview and the mobile web…
• 2 small differences:
– Mobile web authenticates with
web session
– Webview sets up protocols links
18.
19.
20. Webview and the mobile web…
• 1 big difference:
– Through webviews we can
access native capabilities
21.
22. Pitfalls…experiences?
• Android webview has a lot of bugs
• Too heavy widget (poor performance?)
• Differente capabilities depending on the OS
version.
• Cordova webview implementation (not a silver
bullet)
23. Some advice…and conclusions…
Minimize number of connections
Do not assume JS has loaded
Minimize page weight
Testing in your desktop is not enough
Do not resize images on the client
Have a version of the web that works
everywhere
• The most important: know your users
• Test on real devices
