Configuring Applications

This topic describes Web application configuration, especially for privileges and features specific to Samsung Signage's. Many privileges and features available for mobile and wearable Web applications are also available for SSSP applications.

All Tizen Web application projects must have a "config.xml" file in the project root directory. The configuration file is composed of XML elements, including the <widget> element as its root. The configuration information is used when you install or run the Tizen Web application.

The "config.xml" file contains the following information:

  • Application ID
    The Samsung Smart Signage SDK automatically creates an application ID, which uniquely identifies the application within the package.
    <tizen:application id='{Package}.{Project Name}' ... />
  • Application version
    The application version format is "x.y.z".
    <widget … version='{0-255}.{0-255}.{0-65535}' ... />
  • Application icon
    File path for the launcher icon.
     <icon src='Icon Path' />
  • HTML content
    File path for the start-up file of the Web application. By default, it is the "index.html" file in the root directory.
    <content src='HTML Path' />
  • Privileges
    Tizen and SSSP APIs that handle platform and user-sensitive data require privileges that must be declared before the APIs can be used.
    <tizen privilege name=' Name' /><tizen privilege name=' Name' />
  • Network access policy
    According to the W3C Access Requests Policy (WARP), you cannot access network resources by default. For more information, see Defining External Access Policies in the Policy Tab.
  • Meta data features
    Some features, such as prelaunching, are implemented by adding values to the metadata element.
  • Mouse support
    Interaction with the application using a mouse, is enabled by default. If you want to disable it for your application, add the following line to the "config.xml" file:
    <tizen:setting pointing-device-support='disable' /> 

In the Tizen Studio, you can edit the configuration file in 2 ways:

  • Web Configuration Editor
    You can easily set the project configuration (manifest) using a form editor, even if you have no experience in developing a Tizen Web application project.
  • Configuration source editor
    If you are fluent in the configuration file XML structure, you can modify the XML structure directly through the configuration source editor.

For more information, see Setting Project Properties and Configuring Applications.


To use security-sensitive APIs, you must declare the required privileges and sign your application with a certificate for the appropriate privilege level. You can add privileges to the "config.xml" file using the "Privileges" tab of the Configuration Editor in the Tizen Studio.

# Meta Data

Some features are implemented by adding key-value pairs to the metadata element. You can add meta data in the "Tizen" tab of the Configuration Editor in the Tizen Studio.
