“It takes us months, no, years to release updates”
“Our IT budgets are shrinking, not growing”
“We can’t hire new iOS & Android developers”
“We need cross platform support to reduce costs”
“We want offline support with maximum security”
“We don’t want to change our existing architectures”

Mobile Application Framework (MAF)
MAF Application Structure
“The content of a MAF application is comprised of one or more embedded
applications known as application features, which are represented as icons within
the application's springboard or navigation bar”
Springboard
• Is the landing screen where all of the apps/features are displayed (desktop
of the phone/application)
Features
• are essentially the building blocks of a mobile application
• perform a specific set of tasks like managing customer contacts or listing
the product inventory
• are independent of one another, each application feature has its own class
loader and web view
virtual7 – The Oracle Middleware Experts
Mobile Application Framework (MAF)
Creating a MAF Application
• Choose File, then New, and then Application, and choose the
Mobile Application Framework Application template
• This generates an application with 2 projects
 ApplicationController Project – houses application implementation
files like definitions of skins or application lifecycle listener (ALCL)
 ViewController Project - houses resources and implementation
for the application features
 Application Resources – application level configuration files for
defining application name, content, springboard, database
connections, web-service policies, JVM startup settings, etc.

Mobile Application Framework (MAF)
Creating Features
ViewController -> adfmf-feature.xml – the configuration file for declaring features
virtual7 – The Oracle Middleware Experts
Mobile Application Framework (MAF)
Referencing Features
Application Resources -> maf-application.xml – is the application configuration file
• Feature References – used for adding features used in the application
 Select one of the defined feature
 Configure if it will be shown in the default navigation bar
 Configure if it will be shown in the default springboard

Configuring the Springboard
Application Resources -> maf-application.xml – is the application configuration file
• Application – application configuration

Application Name
Lifecycle Event Listener Class
Navigation Bar configuration
Springboard configuration (none, default,
custom)

UI - Web View
Web View - Uses a mobile device's web engine to display and process web-based
content. In a MAF application, the web view delivers the user interface by rendering
the application mark-up as HTML 5.

Mobile Application Framework (MAF)
UI - Web View – Feature Content Types
• MAF AMX
 JSF-like file / page flow, built visually in JDeveloper
 Generated into HTML/JS on device at RT
 Based on HTML5
• Local HTML
 Hand-coded HTML5 pages
• Remote URL
 Hand-coded HTML5 pages
virtual7 – The Oracle Middleware Experts

Building AMX Pages
• JSF-Like implementation using components
• JDeveloper:
 Components wizard - Drag and drop functionality
 Property Inspector
 Preview panel

Accessing Device Features
Cordova - The Apache Cordova JavaScript APIs integrate the device's native
features and services into a mobile application. You can access these APIs
programmatically from Java/Javascript code or you can add device integration
declaratively when you create MAF AMX pages because MAF packages these APIs
as data controls.

Business Logic and Data
Business Logic and Data – MAF comes with a set of features suited for
implementing business logic, data definition and data access, by the means of a
JVM, APIs for DB and Web Service access and an own Encrypted SQLite DB
virtual7 – The Oracle Middleware Experts
Mobile Application Framework (MAF)
Business Logic and Data
• Java Virtual Machine - Java provides a Java runtime environment for a MAF application. This
JVM is implemented in device-native code, and is embedded (or compiled) into each instance
of the MAF application as part of the native application binary.
 Business Logic - Java enables the business logic in MAF applications trough Managed
Beans (similar to JSF Managed Beans)
 Model - Contains the binding layer that connects the business logic components with the
user interface. In addition, the binding layer provides the execution logic to invoke REST
or SOAP-based web services.
 JDBC - The JDBC API enables the model layer to access the data in the encrypted
SQLite database through CRUD (Create, Read, Update and Delete) operations.
• Encrypted SQLite Database - the MAF application generates this lightweight, cross-platform
relational database. Because this database is encrypted, it secures data if the device is lost or
stolen. Only users who enter the correct user name and password can access the data in the
local database

Push Notifications
Push Handler - Enables the MAF application to receive events from the iOS or
Android notification servers. The Java layer handles the notification processing.

Push Notifications – Implementation
1. Registering the ApplicationLifeCycleListener …
 Where? Remember? … Application Resources -> maf-application.xml – is the application
configuration file
2. … so that on start of the application to register a new PushNotificationListener
 How? – Implement Java code in the start() method of the LifeCycleListener

Push Notifications – Implementation
3. … with the PushNotificationListener being a concrete EventListener
4. … which onOpen() receives the token and stores it as the deviceToken
 How? – Implement Java code in the onOpen() method of the PushNotificationListener
