ADF Mobile enables you to create an application that can house different types of content that runs on mobile devices powered by Apple iOS platforms or Android devices. This section of the tutorial walks you through configuring your environment so that you can develop and test ADF Mobile applications using JDeveloper and an Android environment. In this section you configure build and test small application using the Android environment and emulator. Although we are configuring the environment to use an emulator, you can also deploy to an actual Android device.

The images below show you what your simulator will look like when you successfully complete the tutorial.

Step 2: Create an ADF Mobile Application

    In this part of the tutorial, you create and deploy a “Hello World” ADF Mobile application to the Android emulator. Preparing ADF Mobile Framework applications for deployment is primarily comprised of creating platform-specific deployment profiles.
    A deployment profile defines how an application is packaged into the archive that will be deployed to either an iOS or Android platform.
    The deployment profile:
    - Specifies the format and contents of the archive.
    - Lists the source files, deployment descriptors, and other auxiliary files that will be packaged into the archive file.
    - Describes the type and name of the archive file to be created.
    - Highlights dependency information, platform-specific instructions, and other information.

  1. In the Application Navigator click New Application to start the New Gallery dialog box.

    New Application
  2. In the New Gallery expand the General - Applications nodes and select Mobile Application (ADF) and click OK.

  3. In the Name your application page, enter MyMobileApp in the Application Name field, and click Next.

    name mobile application

  4. Click Next, and examine the Project Features for your second project, ApplicationController. The project includes the ADF Mobile Framework.

  6. Click Next and Finish. In the Application Navigator, all the files associated with a new ADF Mobile application are viewable.

    After you complete an ADF Mobile Framework application, JDeveloper adds both project and application level artifacts. Among these artifacts is an ADF Mobile framework model project and the view-controller project (with the default name, ViewController) that has the ADF Mobile framework feature application resources. These resources include the configuration file for applications features, adfmf-feature.xml. The configuration file is a stub XML descriptor file that enables you to define feature applications that will be seen when the application runs. The adfmf-feature.xml defines details of each feature - for example, its icon, content type, starting point, etc.

    The adfmf-application.xml file defines the details of the application itself, including reference to features. These feature applications, when packaged into a JAR file known as a Feature Archive file (FAR), provide the reusable content that can be consumed by other ADF Mobile applications. One reason for this distinction is to allow developers to create feature archives (which may contain one or more features referenced in the adfmf-feature.xml), and then create applications by simply pulling in feature archives.  Of course each app would only have one adfmf-application.xml.

    A FAR is essentially a self-contained collection of everything that a feature requires, such as icon images, resource bundles, HTML, JavaScript, or other implementation-specific files. The FAR includes a single adfmf-feature.xml file, which identifies each of the packaged feature applications by a unique ID. You can edit this file to update feature properties. For example, you can specify the content implementation (local or remote HTML files, AMX pages, or a native application written in platform-specific language). You can also control the display of content based on such factors as user roles and privileges, or device properties. A mobile application can reference one FAR, several of them, or none at all.

  7. Right-click on the ViewController project and select New
    In the New Gallery, select Web Tier - HTML and then the HTML Page item. Click OK.

Step 3: Add UI Access to the Pages

    In this section, you configure a new feature so the user can access the newly defined local HTML page from the native application container. You will need to perform this task whenever you add pages or task flows to your application.

  1. In the Application Navigator, expand the ViewController project. Locate and expand the Application Sources folder. Then expand the META-INF folder. You will see the adfmf-feature.xml file as shown.

    adfmf-feature,xml selected in the applications navigator

  2. Double click on the adfmf-feature.xml file to open the Feature editor.
