Package Manager

The package manager is used to retrieve detailed information on the installed packages on the device. This information includes the package name, label, path to the icon image, version, type, and installed storage.

The main features of the Tizen.Applications.PackageManager class includes the following:

Retrieving information for all installed packages

Use the GetPackages() method of the Tizen.Applications.PackageManager class to retrieve the package information for all installed packages. The method returns an IEnumerable<Package> object with the package information.
Retrieving individual package information

To retrieve package information, get the Tizen.Applications.Package object using the GetPackage() method of the Tizen.Applications.PackageManager class.
Monitoring changes

You can monitor package events, such as installation, uninstallation, and updates.
Removing package user data

You can clear user data by targeting a specific file or directory. (Since Tizen 8.0)

Prerequisites

To enable your application to use the package management functionality, follow these steps:

To use the Tizen.Applications.PackageManager class, the application has to request permission by adding the following privilege to the tizen-manifest.xml file:


                XML
                
                    Copy
                    
                
            
<privileges>
   <privilege>http://tizen.org/privilege/packagemanager.info</privilege>
</privileges>

To use the methods and properties of the Tizen.Applications.PackageManager class, include the Tizen.Applications namespace in your application:


                C#
                
                    Copy
                    
                
            
using Tizen.Applications;

Retrieve all package information

To retrieve all package information for installed packages, follow these steps:

Retrieve all package information with the GetPackages() method of the Tizen.Applications.PackageManager class:


                C#
                
                    Copy
                    
                
            
IEnumerable<Package> packageList = PackageManager.GetPackages();

Iterate through the returned list to access information about each Tizen.Applications.Package object:


                C#
                
                    Copy
                    
                
            
foreach (Package package in packageList)
{
    Log.Debug(LogTag, "pkgid: " + package.Id);
    Log.Debug(LogTag, "label: " + package.Label);
    Log.Debug(LogTag, "icon: " + package.IconPath);
    Log.Debug(LogTag, "version: " + package.Version);
    Log.Debug(LogTag, "type: " + package.PackageType);
    Log.Debug(LogTag, "storage: " + package.InstalledStorageType);
    Log.Debug(LogTag, "system: " + package.IsSystemPackage);
    Log.Debug(LogTag, "removable: " + package.IsRemovable);
    Log.Debug(LogTag, "preload: " + package.IsPreloaded);
}

Retrieve specific package information

To get specific package information, follow these steps:

Retrieve information for a specific package with the GetPackage() method of the Tizen.Applications.PackageManager class:


                C#
                
                    Copy
                    
                
            
Package package = PackageManager.GetPackage("org.tizen.helloworld");

Use the Tizen.Applications.Package object returned by the GetPackage() method to access various package details:


                C#
                
                    Copy
                    
                
            
/// Use package information
Log.Debug(LogTag, "pkgid: " + package.Id);
Log.Debug(LogTag, "label: " + package.Label);
Log.Debug(LogTag, "icon: " + package.IconPath);
Log.Debug(LogTag, "version: " + package.Version);
Log.Debug(LogTag, "type: " + package.PackageType);
Log.Debug(LogTag, "storage: " + package.InstalledStorageType);
Log.Debug(LogTag, "system: " + package.IsSystemPackage);
Log.Debug(LogTag, "removable: " + package.IsRemovable);
Log.Debug(LogTag, "preload: " + package.IsPreloaded);

Monitor package events

To detect package-related events, such as installation, uninstallation, and updates, follow the steps below:

The following example registers event handlers for package installation, uninstallation, and update events:


                C#
                
                    Copy
                    
                
            
PackageManager.InstallProgressChanged += new System.EventHandler<PackageManagerEventArgs>(InstallEventHandler);
PackageManager.UninstallProgressChanged += new System.EventHandler<PackageManagerEventArgs>(UninstallEventHandler);
PackageManager.UpdateProgressChanged += new System.EventHandler<PackageManagerEventArgs>(UpdateEventHandler);

Define the event handlers. When the related event occurs, the event handler is triggered and you can get the event details from the Tizen.Applications.PackageManagerEventArgs instance.

The following example implements the installation event handler:


                C#
                
                    Copy
                    
                
            
void InstallEventHandler(object sender, PackageManagerEventArgs args)
{
    Log.Debug(LogTag, "pkgId: " + args.PackageId);
    Log.Debug(LogTag, "pkgType:" + args.PackageType);
    Log.Debug(LogTag, "progress:" + args.Progress);
    Log.Debug(LogTag, "eventState:" + args.State);
}

Clear user data

If you want to delete specific user data from a specific app, you can use the ClearUserData() method of the Tizen.Applications.PackageManager class.

The following example removes the testDir/test.txt file from org.tizen.sample package’s user directory:


                C#
                
                    Copy
                    
                
            
PackageManager.ClearUserData("org.tizen.sample", "testDir/test.txt");

If you want to use this API, you need to add the below privilege on tizen-manifest.xml.
