Agenda
Mobile development strategies
Salesforce Mobile SDK
The “Mobile Chow Finder” application
Technology stack overview• Database.com
• Ruby on Rails
• jQuery Mobile
• Databasedotcom gem
Demo (aka “Show me the code!”)
Native vs. HTML5 vs. Hybrid
Native applications
Pros• Feature rich, look & feel and performance
• Objective-C & Java
• Easy to find applications
• Easy to monetize applications
Cons• Limited to single platform
• Objective-C & Java
• Distribution via Apple App Store and Google Play
HTML5 applications
Pros• A "write one, run many" solution that is cross platform and cross device
• Low barrier to entry - HTML5, CSS3 & JavaScript skills
Cons• Not up to par with the native app experience
“Frameworks”• jQuery Mobile
• Sencha Touch
• jQTouch
Hybrid applications
Pros• Application framework that enables you to build natively installed applications
using HTML, CSS and JavaScript.
• Supports accelerometer, camera, compass, contacts, geolocation, sotification,
storage and more.
• PhoneGap Build – no SDKs to install! Spits out binaries for 7 mobile platforms
• Discover and monetize via App Store and Play
Cons• PhoneGap: Doesn’t look native
• Titanium: Platform specific API via JavaScript for Android & iOS. No HTML or
CSS support.
CloudSpokes HTML5 Apps
Salesforce.com Mobile SDK
Suite of open-source technologies for iOS, Android, HTML5 and hybrid
applications
Sample applications, quick start and webinars
Mobile components for Visualforce
Easy to build jQuery Mobile Visualforce applications
Building the “Mobile Chow Finder”
HTML5 application for service members to find the local “Chow Hall”
Database.com
jQuery Mobile
Ruby on Rails
Geolocation
Store favorites using LocalStorage
jQuery Mobile - View
Super easy! Uses web standard HTML5, CSS3, and JavaScript to easily
develop user interfaces for mobile web apps
Framework built on top of jQuery – EVERYONE loves jQuery!
Provides custom events to detect mobile and touch specific actions like
tap, tap-and-hold, swipe, and orientation change (i.e. rotating the device).
We are just building web pages!!
Database.com - Model
A secure, cloud database for building social and mobile enterprise apps.
Slimmed down version of Force.com database (essentially the Setup
section)• Only custom objects (no CRUD UI)
• Apex classes, triggers & workflow
• Identity & user management plus role and profile security
• Oauth2 & REST baked in
Utilize your favorite Force.com tools
Pricing based upon user licenses, records and transactions
Ruby on Rails - Controller
Great for quickly building social and mobile applications
Leverage thousands of open source packages and frameworks to build
amazing applications.
Databasedotcom Ruby gem• Open source ruby client for accessing REST and Chatter APIs
• Supports OAuth2
• ActiveRecord syntax
• Should be called ‘Forcedotcom’ gem
Host the application on Heroku – WINNING!
Let’s code this sucker up!
