  4. 4. What to Walk Away With Strategies for building mobile applications with the platform. Best practices with mobile application with Ruby on Rails and A deep love and appreciation for the platform.
  5. 5. Agenda Mobile development strategies Salesforce Mobile SDK The “Mobile Chow Finder” application Technology stack overview   Ruby on Rails  jQuery Mobile  Databasedotcom gem  Heroku Demo (aka “Show me the code!”)
  6. 6. Native vs. HTML5 vs. Hybrid
  7. 7. 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
  8. 8. 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 jQuery Mobile Sencha Touch jQTouch
  9. 9. Hybrid ApplicationsPros  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 different mobile platforms  Discover and monetize via App Store and PlayCons  PhoneGap: Doesn’t look native  Titanium: Platform specific API via JavaScript for Android & iOS. No HTML or CSS support.
  10. 10. What Can You Build with PhoneGap?
  11. 11. 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
  12. 12. Building the “Mobile Chow Finder” HTML5 application for service members to find the local “Chow Hall” jQuery Mobile Ruby on Rails Geolocation Store favorites using LocalStorage
  13. 13. 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!!
  14. 14. - Model A secure, cloud database for building social and mobile enterprise apps. Slimmed down version of 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 tools Pricing based upon user licenses, records and transactions
  15. 15. 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!
  16. 16. Let’s Code this Sucker Up!
  17. 17. Recap – What Did We See? Strengths and weaknesses of mobile application development strategies. When to use one versus the other. The Mobile SDK embraces all three development approaches. Advantages of using as a data store. How to quickly and easily develop HTML5 mobile applications using open source technologies. Best practices for developing mobile applications.
