Component Manager

Component manager provides information about installed and running components.

The main features of the Tizen.Applications.ComponentBased.ComponentManager class include:

  • Managing running component context

    For the running components, you can retrieve the component running context and operate on it. You can manage the component running context with the Tizen.Applications.ComponentBased.ComponentManager class.

  • Managing component information

    For components that are installed but not necessarily running, you can retrieve information with the Tizen.Applications.ComponentBased.ComponentInfo class.

Iterator methods are used to travel through a list of components. The GetRunningComponentsAsync() method of the Tizen.Applications.ComponentBased.ComponentManager class is used for the running components and the GetInstalledComponentsAsync() method is used for the installed components.


To enable your application to use the component management functionality:

  1. To use classes and methods, the application has to request permission by adding the following privilege to the tizen-manifest.xml file:

  2. To use the methods and properties of the Tizen.Applications.ComponentBased.ComponentManager, Tizen.Applications.ComponentBased.ComponentRunningContext, and Tizen.Applications.ComponentBased.ComponentInfo classes, include the Tizen.Applications.ComponentBased namespace in your application:

    using Tizen.Applications.ComponentBased;

Managing Running Component Context

To get the running component context and its details, and to operate on the context:

  1. Get the context of the currently running component by creating an instance of the Tizen.Applications.ComponentBased.ComponentRunningContext class, with the ID of the context obtained component as a parameter.

    To get a component’s context, the component must be running.

    ComponentRunningContext compoRunningContext = new ComponentRunningContext(Your Component ID);
  2. Operate on the context:

    • Get the component ID, application ID, and instance ID from the context:

      string componentId = compoRunningContext.ComponentId;
      string applicationId = compoRunningContext.ApplicationId;
      string instanceId = compoRunningContext.InstanceId;
    • Check the state of the component:

      if (compoRunningContext.State == ComponentRunningContext.ComponentState.Initialized)
          /// The component is constructed.
      else if (compoRunningContext.State == ComponentRunningContext.ComponentState.Created)
          /// The component is created.
      else if (compoRunningContext.State == ComponentRunningContext.ComponentState.Started)
          /// The component is started.
      else if (compoRunningContext.State == ComponentRunningContext.ComponentState.Resumed)
          /// The component is resumed.
      else if (compoRunningContext.State == ComponentRunningContext.ComponentState.Paused)
          /// The component is paused
      else if (compoRunningContext.State == ComponentRunningContext.ComponentState.Destroyed)
          /// The component is destroyed.
          /// State is undefined
    • Resume the running application:


Managing Component Information

To get the installed information and its details, and to operate on the information:

  1. Get the information of the currently-installed component by creating an instance of the Tizen.Applications.ComponentBased.ComponentInfo class, with the ID of information obtained component as a parameter.

    To get a component’s information, the component must be installed.

    ComponentInfo compoInfo = new ComponentInfo(Your Component ID);
  2. Operate on the information:

    • Get the component ID and application ID:

      string componentId = compoInfo.ComponentId;
      string applicationId = compoInfo.ApplicationId;
    • Check the type of the component:

      if (compoInfo.ComponentType == ComponentType.Frame)
          /// The component is frame-component.
      else if (compoInfo.ComponentType == ComponentType.Service)
          /// The component is service-component
          /// ComponentType is undefined
    • Get the label and the icon path:

      string label = compoInfo.Label;
      string iconPath = compoInfo.IconPath;
  3. Call the GetInstalledComponentsAsync() method of the Tizen.Applications.ComponentBased.ComponentManager class, and retrieve all components and print their information:

    IEnumerable<ComponentInfo> compoInfoList = await ComponentManager.GetInstalledComponentsAsync();
    foreach (ComponentInfo compoInfo in compoInfoList)
        Log.Debug("Tag", "componentId: " + compoInfo.ComponentId);
        Log.Debug("Tag", "applicationId: " + compoInfo.ApplicationId);
        Log.Debug("Tag", "label: " + compoInfo.Label);
        Log.Debug("Tag", "iconPath: " + compoInfo.IconPath);
        Log.Debug("Tag", "ComponentType: " + compoInfo.ComponentType.ToString());
        Log.Debug("Tag", "isIconDisplayed: " + compoInfo.IsIconDisplayed.ToString());
        Log.Debug("Tag", "isManagedByTaskManager: " + compoInfo.IsManagedByTaskManager.ToString());
