10 Things
One App….. …. 10 Things ….. …. In 45 Minutes…. ….Really…?
Remote URLs
• For embedding existing web pages in your ADF Mobile app.
• For instance: – News Website – Existing enterprise app Mobile Browser Pages
• Note: – Best use Optimized Mobile Browser Pages – Apache Trinidad components – Oracle recommends using ADF Mobile browser
Feature as Remote URL
• Create New Feature as Remote URL
• Create URL Connection
Whitelisting
• Why do we need to do this ?
• Mobile device is redirected to m.uefa.com
Property Change Events
• Raised when individual attributes of a model object are changed
• Use setter method to update attributes
Provider Change Event
• Raised when attributes of type Collection are changed on a model object
• When a new row is created – fireProviderCreate(providerKey, rowKey, newRow) – New row is inserted in the UI without refreshing other parts of the page
• When a row is deleted – fireProviderDelete(providerKey, rowKey) – Row is deleted in the Iterator
• When the collection is refreshed – fireProviderRefresh(providerKey) – Iterator is refreshed – Row currency is lost.
providerChangeSupport.fireProviderRefresh("stadiums");!
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, 200, 200);
DeviceManager.CAMERA_SOURCETYPE__PHOTOLIBRARY
Be careful !!
• DESTINATIONTYPE_DATA_URL you will get the image as base64 encoded string
• Camera’s are very good and 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 memory
issues – On Android out-of-memory can be caused with default image settings. Make
image smaller by setting targetWidth and targetHeight
• Small sized images can be uploaded using web services.

Using Webservices
• The Webservice Datacontrol
Using Webservices directly
• Just drag & drop the method from the Data Control
Using Webservices from Java
• Invoke directly from java. • Does not use the binding layer
• Uses Framework utilityMethod • AdfmfJavaUtilities.invokeDataControlMethod()
• Datacontrol must be in available in DataBindings.cpx
Advantages
• Provides more flexibility to shape model to mobile UI • Perform client side validation • Minimize the number of round trips • Offline caching • Mash-up data from multiple services
Patterns…
• SOAP Webservice • Web Service Data Control
Patterns…
• REST Webservice • Rest Service Adapter
Patterns….
• SQLite Database • Plain JDBC
Obviously all the same……
• Service Object Data Control Pattern
– Whatever “back end” data source you use…..
– It is completely transparent for UI
Feature Archives
• Feature Archives can be reused
• Deploy ADF Mobile app as FAR • Consume features from FAR in other apps
Feature Archives
• Feature Archives Deployment Profile
• Connections Detail should be used (default is wrong ?)
• Only if connection is available in consuming APP name only works
Springboard & navigationbar
• Springboard configuration in adfmf-application.xml
The Default Springboard
The Custom SpringBoard
Configuring the springboard
– Do Not set AllowDeviceAccess to False for Springboard Feature !
Navigation
• Declarative Navigation – Button/Link/ListItem
<amx:listItem id="li1" action="detail" showLinkIcon="true">! <amx:setPropertyListener id="x" from="#{row.rowKey}” to="#{pageFlowScope.myBean.currentStadium}" ! type="action"/>!
Navigation
• Declarative Navigation – Button/Link/ListItem
• Programmatic Navigation – JavaCode
AdfmfContainerUtilities.invokeContainerJavaScriptFunction(! AdfmfJavaUtilities.getFeatureName(), ! "adf.mf.api.amx.doNavigation", ! new Object[] { ”detail" }); } !
Navigation
• Drawback – No access to setPropertyListener
• Solution if you need that functionality: – Set the value in java Code
ValueExpression ve =! AdfmfJavaUtilities.getValueExpression(! "#{pageFlowScope.myBean.currentStadium}”! , String.class);!ve.setValue(AdfmfJavaUtilities.getAdfELContext()! , getCurrentStadium());!
Smart Navigation
• Search Stadiums
• What if resultset only contains one row ?
if (s_stadiums.size()==1){! // only one stadium! Lets navigate AdfmfContainerUtilities.invokeContainerJavaScriptFunction(! AdfmfJavaUtilities.getFeatureName(), ! "adf.mf.api.amx.doNavigation", ! new Object[] { "detail" });!} !
Preserve Current Row
• 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.
Preserve Current Row (A-Team)
• Easiest way: – Download and install extension – adf-mobile-persistence-sample-install.zip – Extension contains StatefulIteratorBeanDcDefinition
• NOTE: This will be the way ADF Mobile will do it in future versions
<AdapterDataControl id="PlayerService” FactoryClass="oracle.adf.model.adapter.DataControlFactoryImpl” ImplDef= "oracle.ateam.sample.mobile.model.bean.StatefulIteratorBeanDcDefinition”! ………. Definition= "com.blogspot.lucbors.soccer.mobile.model.service.PlayerService” BeanClass= "com.blogspot.lucbors.soccer.mobile.model.service.PlayerService"! } !
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“ />
Use case example
Ingredients
• A (Web) service and datacontrol • A Page with Listview • An ActionListener with type
SwipeDown • Smart Java Code to call service
conditionally
<amx:listView var="row”! value="#{bindings.allLocations.collectionModel}" ! fetchSize="#{bindings.allLocations.rangeSize}”! id="lv1"> ! <amx:listItem id="li1"> ! <amx:actionListener type="swipeDown” ! binding="#{pageFlowScope.locationsBackingBean.checkForUpdates}”>! !
Change the data
Swimming-lanes
• No Horizontal scrollbar • All ‘data’ available
• Use panelGroupLayout – Width 100%
<amx:panelGroupLayout layout="horizontal” inlineStyle="width:100%;">!
Push Notification (GCM)
• Subscribe to GCM • Receive token • Register with Enterprise app • Enterprise app Pushes message to
GCM • GCM delegates message to
device(s)
Server Side
• Class to push a message to a device. – import com.google.android.gcm.server.Constants; – import com.google.android.gcm.server.Message; – import com.google.android.gcm.server.Result; – import com.google.android.gcm.server.Sender;
public class PushMessageBean { public String message; private Sender sender = new Sender(”<someSenderKey>"); public static final String ERROR_NOT_REGISTERED="NotRegistered”; private Message createMessage(String msg) { String sound = "default"; Message message = new Message.Builder().collapseKey("1") .delayWhileIdle(true) .addData("alert", msg) .addData("sound", sound).build(); return message;}
Server Side Send Code
public void pushNow(ActionEvent actionEvent) { // Add event code here… DCBindingContainer bindings = (DCBindingContainer) BindingContext.getCurrent().getCurrentBindingsEntry(); DCIteratorBinding iter = bindings.findIteratorBinding("GcmSubscribersIterator"); Row curr = iter.getCurrentRow(); String target = (String)curr.getAttribute("DeviceToken"); String type = (String)curr.getAttribute("DeviceType"); if(type.equalsIgnoreCase("Android")){ Message message = createMessage(this.message); Result result = null; sendSingleMessage(target, message); }
Example
• Select device
• Send message
• Get notified
