ADF mobile vs. Vanilla ADF
• The Obvious Differences
• The Annoying Differences
• The Not so Obvious Differences
• The Nice Differences
The 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“ />
Annoying differences
A simple calculator….
• In Vanilla ADF…… • InputText for Value • Autosubmit
• OutputText for Result • PartialTriggers
• Managed Bean • Holds the values
This is annoying….
• ADF Mobile • Autosubmit and PartialTriggers does not exist !
• 2 Options
I. Use application Scoped Variables (no Coding) • Not meant for this purpose
II. Use the Property Change Listener Pattern
PropertyChangeSupport
The not so obvious ones
• No menu structure….. • What about Application Start ? • What about Navigation ?
• No ADF Business Components • Now what ?
Springboard & navigationbar
• Springboard configuration in adfmf-application.xml
The Default Springboard
The Custom SpringBoard
Configuring the springboard
Using the Local Database
Creating the Local Database
Register Listener
Using the POJO Datacontrol
Talking to the DB (Select)
Talking to the DB (DML…)
Using Webservices
• Create a Webserivce Datacontrol
Using Webservices (1)
• Just drag & drop the method from the Data Control
Using Webservices (1)
• The PageDefinition File
• The PageDefinition
Using Webservices (2)
• 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(); } }
The return of the invokeAction
• The current row in ADF Mobile is not preserved across pages that bind to the same data collection
• Steps: – Inside the <amx:listItem> element of the list page, you need to add a
<amx:setPropertyListener> element to store the row key in a pageFlowScope variable.
– In the page definition of the detail page, you need to add a setCurrentRowWithKey action, which uses the pageFlowScope variable to set the current row.
– In the page definition of the detail page, you need to add an invokeAction executable for the setCurrentRowWithKey action to ensure the current row is automatically set when entering the detail page.

The Nice Differences
• Device Interaction
• Thematic Maps
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
Demo
I wish ADF could do this
Custom Thematic Map
• Configuration File
• Custom Image
Custom Thematic Map
Custom Thematic Map
Demo
Summary
• Today was about differences • Know the differences • Know the ADF Mobile way to do it
• There are many parallels • Developing ‘feels’ like Vanilla ADF • Component Based Developement • ADF ‘like’ config files • DataControl / DataBinding
• My advise • Use ADF Mobile like ADF • Know The DataControl by heart • Know how to use Multiple (levels) of Datacontrols • Use Java; it is more flexible then declarative
