The Rhomobile Mission
Mobilize enterprise apps… cost-effectively witha great user experience. -provide the high level productivity and portability of
web programming- with device optimization and offline capability of “native mobile apps”- open source for rapid adoption by developers
Background
- Smartphones sales are exploding- Five major smartphone operating systems: iPhone, BlackBerry, Windows Mobile, Symbian, Android
- Growth leaders are installed base laggards- “native apps” have won the day
-500 million iPhone app downloads on a platform with great browser installed
But …how do you write an app for all popular devices?
A Better Way… Rhomobile
- Build the app quickly in HTML and Ruby- Write it once and it runs on all smartphones- Work with synced local data- Exploit device capabilities (GPS, PIM data)- Available open source: http://github.com/rhomobile
The Rhomobile Components
Rhodes “microframework” for building locally
executing natively optimized mobile apps Developers run app generator for their objects
of interest and then edit HTML templates Contains first mobile Ruby implementation
RhoSync Sync focused on web service data (needed in
the age of SaaS) Handles keeping your data local on the device

Building a Rhodes App
• Get your data (RhoSync)• Create a sync source• Define your sync source adapter code• Test it from the RhoSync web interface
• Generate your app (RhoGen)• Generate an app (in the Rhodes \apps subdirectory)• Generate scaffold code for the model
• Develop your app (Ruby/HTML editor of choice)• Edit your model controllers• Edit your HTML templates (ERB file)
• Build, test, deploy (development environment for device) • Build your app• Test your app• Make available for download (or submit to an
AppStore)

Defining a Rhosync Source
Provide a Source Adapter class with• login- authentication code for the backend• query - retrieve or read's objects from the
backend source• sync - take apart these objects and put
them into a "property bag” • create • update• delete• logoff
Generated Source Adapter Class
class <%=name%> < SourceAdapter def initialize(source) super end
def login #TODO: Write some code here end
def query # TODO: write some code here end
def sync # usually the generic base class sync does the job super end
def create(name_value_list) #TODO: write some code here end
def update(name_value_list) #TODO: write some code here end
def delete(name_value_list) #TODO: write some code here if applicable end
def logoff #TODO: write some code here if applicable end
end

Why Rhomobile?
Declarative tag-based approach (web programming) is more productive
Rich client against local data much better than remote web apps
Write it once and it works on all smartphones
