PackageInstaller Class

To install an application do the following steps:
  1. Obtain an instance of PackageInstaller with [!:Com.Datalogic.Device.App.PackageInstaller.PackageInstaller(Context)]. -
  2. Obtain an instance of IPackageInstallerListener that will be used to handle the result of the command. This object must be passed as parameter to the install method. -
  3. To perform the install session call [!:Com.Datalogic.Device.App.PackageInstaller.install(java.lang.String,%20boolean,%20com.datalogic.device.app.PackageInstallerListener)]. The method onResult of the listener will be called when the install session has completely finished, either with success or failure. -

Remarks
PackageInstaller gives developers the ability to install, uninstall and upgrade applications in unattended/silent mode. The install/uninstall/upgrade/selfUpgrade methods are asynchronous. An object that implements PackageInstallerListener must be passed to PackageInstaller to be able to handle the result.
An install/uninstall/upgrade method can be executed alone calling the corresponding method of the PackageInstaller or together with other methods grouped in a PackageInstallerSession. In the former case there will be a result callback for each method, in the latter case there will be only one callback listing the results of each method. The methods grouped in a PackageInstallerSession are executed in best effort.

To install an application do the following steps:

  1. Obtain an instance of PackageInstaller with [!:Com.Datalogic.Device.App.PackageInstaller.PackageInstaller(Context)]. -
  2. Obtain an instance of IPackageInstallerListener that will be used to handle the result of the command. This object must be passed as parameter to the install method. -
  3. To perform the install session call [!:Com.Datalogic.Device.App.PackageInstaller.install(java.lang.String,%20boolean,%20com.datalogic.device.app.PackageInstallerListener)]. The method onResult of the listener will be called when the install session has completely finished, either with success or failure. -

To uninstall an application do the following steps:

  1. Obtain an instance of PackageInstaller with [!:Com.Datalogic.Device.App.PackageInstaller.PackageInstaller(Context)]. -
  2. Obtain an instance of IPackageInstallerListener that will be used to handle the result of the command. This object must be passed as parameter to the uninstall method. -
  3. To perform the uninstall session call [!:Com.Datalogic.Device.App.PackageInstaller.uninstall(java.lang.String,%20com.datalogic.device.app.PackageInstallerListener)]. The method onResult of the listener will be called when the uninstall session has completely finished, either with success or failure. -

To upgrade an application do the following steps:

  1. Obtain an instance of PackageInstaller with [!:Com.Datalogic.Device.App.PackageInstaller.PackageInstaller(Context)]. -
  2. Obtain an instance of IPackageInstallerListener that will be used to handle the result of the command. This object must be passed as parameter to the upgrade method. -
  3. To perform the upgrade session call [!:Com.Datalogic.Device.App.PackageInstaller.upgrade(java.lang.String,%20com.datalogic.device.app.PackageInstallerListener)]. The method onResult of the listener will be called when the upgrade session has completely finished, either with success or failure. -

To execute more install/uninstall/upgrade methods and be notified of the results when all the methods have completed, do the following steps:

  1. Obtain an instance of PackageInstaller with [!:Com.Datalogic.Device.App.PackageInstaller.PackageInstaller(Context)]. -
  2. Obtain an instance of IPackageInstallerListener that will be used to handle the result of the commands. This object must be passed as parameter to the createSession method. -
  3. Obtain an instance of PackageInstallerSession with CreateSession(IPackageInstallerListener). -
  4. Open a transaction on the session calling OpenSession. -
  5. Call the methods [!:Com.Datalogic.Device.App.PackageInstallerSession.install(java.lang.String,%20boolean)], Uninstall(String), Upgrade(String) that suite you. -
  6. Close and commit the transaction on the session calling CloseSession. -
  7. The method onResult of the listener will be called when all the methods listed in the session have completed, either with success or failure. -

To upgrade the current application do the following steps:

  1. Obtain an instance of PackageInstaller with [!:Com.Datalogic.Device.App.PackageInstaller.PackageInstaller(Context)]. -
  2. Call SelfUpgrade(String) passing as parameter the name of the package to be used to upgrade the current application. -
