ADF Mobile



•  Develop ADF Applications for Mobile Browsers –  Trinidad Components for UI –  ADF Model / Databinding –  ADF Business Components

•  Supported through JavaServer Faces Trinidad Components and Mobile Optimized CSS

•  Use the skills you have –  AJAX functionality such as PPR –  60 Trinidad JSF Components

ADF Mobile Browser

•  For ADF Mobile browser, you implement skinning by performing the following tasks: •  In the trinidad-config.xml component

•  define the <skin-family> tag with the EL (Expression Language) expression, #{requestContext.agent.skinFamilyType}

that returns the skin family type of the browser. •  In trinidad-skins.xml

•  Specify the renderkit and style sheet •  Include the CSS files within the ADF Mobile browser

project •  In ADF 11g R2 this is created and configured by default

Skinning to achieve Look And Feel

•  Use a goLink or goButton to invoke phone:

•  Use a goLink or goButton to invoke email:

<tr:goLink styleClass="messageText" text="#{sessionScope.empDetails.PhoneNumber}” destination="tel:#{sessionScope.empDetails.PhoneNumber}”/>

<tr:goLink styleClass="messageText" text="#{sessionScope.empDetails.Email}" destination="mailto:#{sessionScope.empDetails.Email}"/>

ADF Mobile



•  Declaratively develop hybrid on-device apps •  Access local storage and device services (camera, bar

scanner, etc.) •  Reuse existing ADF development skills •  Minimize development cycle for supporting new mobile platforms

ADF Mobile

•  Device native user experience •  Spring board and tab bar for feature navigation •  Advanced HTML5-based UI

•  Full animation, gesture, and touch interaction support •  Interactive Data Visualization Components

Native Mobile User Experience

•  Thin native application container provides device services integration

•  Leverages Open Sourced PhoneGap

•  Abstracted for easy integration •  Common interface across all

platforms •  Gracefully handle device services

availability

Tight Device Services Integration

•  Local AMX File –  JSF-like file built visually in Jdeveloper –  Generated into HTML/JS on device at RT –  Based on HTML5

•  Remote URL –  ADF Trinidad for Smartphones –  ADF Faces on Tablets –  Any third-party site

•  Local HTML File –  Hand-coded HTML5 pages

Adf mobile – ui content options

•  Development Machine: –  Mac is required if you intend to support iOS devices

•  Mobile development SDKs and simulators –  Used by JDeveloper to compile device native binaries

•  Mobile developer program membership –  Needed to deploy to an actual device

•  Install JDev and download/install the ADF Mobile extension

•  Configure ADF Mobile extension preferences

Development Environment

•  Understand application requirements based on use cases –  Off-line capable or online only –  Device services integration requirements –  Server-side data source and protocol

•  SOAP, REST-XML with XSD, or REST-JSON

•  Application Design –  Server-side services: need to optimize for mobile access –  Client business services: Java modules and data controls –  Features & Client UI: wireframe for views and task flow

Development Roadmap

•  Create server-side services and corresponding client-side data controls

•  For basic mobile applications, create task flow and views that directly consume server-side web (SOAP or REST) services

•  For more complex mobile applications, develop Java classes backing user interface and bean data control –  Retrieves data, instantiates data objects, provide

implementation for methods, and refreshes UI –  Needed when WS DC does not provide sufficient

functionality

Development Roadmap

•  Create task flow, views, and features –  Bind to the Java beans and bean DC created above –  Consider different form factors. Typically you would need

two sets of task flows and views between smart phone and tablets

–  Add device data controls invocation and processing call/code

–  Configure application features •  Deploy application and test on simulators and devices

–  Adjust UI based on user feedback •  Configure and enable security

Development Roadmap

•  Implement Java code to access server-side data –  For online only applications, these Java classes would directly invoke web

services •  For SOAP or REST-XML data sources, invoke through data controls •  For JSON, invoke data sources directly

–  For off-line capable applications, these Java classes would populate data into the local SQLite DB

•  UI would be backed by data in SQLite DB

Development Roadmap

•  Deploy application to simulator and test devices in a test environment

•  Performance optimization

•  Deploy to production environment –  Through external App Store or internal Enterprise App

Store

Obvious Differences

•  Mobile

•  Multiple Platforms

•  Multiple Form Factors

•  Touchscreens

What Device are you on ?

•  Device info

•  Device Properties

Work With Form Factors

•  Respond to Form Factors •  Conditionally Render Different content

Demo

Using the mouse for…..

•  Clicking Menu Items •  Clicking Links & Buttons •  Expanding / Collapsing •  Selecting / Deselecting

Gesture Support

•  You can configure Button, Link, and List Item components to react to the following gestures:

•  Swipe to the right •  Swipe to the left •  Swipe up •  Swipe down •  Tap-and-hold

Gesture examples

•  The Swipe Gesture

•  The Tap Gesture

<amx:actionListener binding="#{mybean.DoX}" type="swipeRight"/>

<amx:showPopupBehavior popupid="pop1" type="tapHold“ />

Springboard & navigationbar

•  Springboard configuration in adfmf-application.xml

Talking to the DB (DML…)

Using Webservices

•  Create a Webserivce Datacontrol

Using Webservices (1)

•  Just drag & drop the method from the Data Control


•  The PageDefinition File

•  The PageDefinition


•  Invoke directly from java. •  Does not use the binding layer

•  Uses Framework utilityMethod •  AdfmfJavaUtilities.invokeDataControlMethod()

•  Datacontrol must be in available in DataBindings.cpx

Advice

•  Do Not Hook Up Webservices Directly to Your Page

–  Use Multiple Layers of Datacontrols For Abstraction

–  You are in control

Demo

Use Caching

•  By default the webservice will be called on every request

•  Simply compare if what is in memory is the same as what needs to be shown.

if (!s_locationsList.isEmpty()){ MyLocation cur = (MyLocation)s_locationsList.get(0); Integer currentLoc = cur.getId(); if (currentLoc.compareTo(Integer.valueOf(<NEWVALUE>))!=0){ // clear cache callWebservice(); } }

Device Interaction

•  The Device Datacontrol

•  Drag n Drop support

•  Attributes as fields

•  Operations as buttons

Camera interaction

•  Take a picture ……………

•  …… or get one from the Library

import oracle.adf.model.datacontrols.device; DeviceManagerFactory.getDeviceManager().getPicture(100, DeviceManager.CAMERA_DESTINATIONTYPE_FILE_URI, DeviceManager.CAMERA_SOURCETYPE_CAMERA, false, DeviceManager.CAMERA_ENCODINGTYPE_PNG, 0, 0);

DeviceManager.CAMERA_SOURCETYPE__PHOTOLIBRARY

Be careful !!

•  DESTINATIONTYPE_DATA_URL you will get the image as base64 encoded string

•  Camera’s are very good. •  Picture quality is amazing.

–  Encoding such images as base64 causes memory issues

•  Don’t blow up your app. –  iOS you should set quality parameter to a value less then 50 to avoid –  On Android out-of-memory can be caused with default image settings. Make

image smaller by setting targetWidth and targetHeight

FileContent Display

•  Integration with Device Native Viewers

•  Exposed as displayFile on DataControl

•  On Android: Use FileType to start appropriate viewer

•  On iOS QuickLook Preview is used

Access and Security

•  Authentication: –  SSO Integration across Features –  OAM/OID support (i.e. integration with Fusion Middleware) –  Can support offline authentication

•  Access Control: –  Role based access (show/hide UI)

•  Encryption: –  Credential store –  Local data –  Communication channels

Example Authentication

•  Use ADF Authentication

•  Secured ADF Application on WLS

Enable Feature Security

Mobile Design and UX

•  Know your users •  Define the essential mobile task •  Design contextually •  Flatten the navigation model •  Design for two minutes to get tasks done •  Integrate analytics •  Simplify searching requirements •  Embed collaboration •  Disclose information progressively •  Leverage platform capabilities
