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

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
