Unable to change app icon of custom app

Environment 

• Knox Configure (KC)

Overview

In KC, when an administrator tries to change a custom app's icon in a profile that was set by a different administrator, the icon is not changed. The following error is shown in the device logs:

11-22 11:30:44.302  1000  1213  7317 D ApplicationPolicy: changeApplicationIcon:packageName com.samsung.android.messagingcalled from :10167
            11-22 11:30:44.304  1000  1213  7317 E ApplicationIconDb: updateApplicationIcon(): invalid ownerUid

Cause

In KC, an icon set by one administrator cannot be changed by a second administrator. This behavior is by API design. 

Resolution

To change the app icon, please ensure that the original administrator who set the app icon makes the update in the KC profile.

Alternatively, Role-Based Access Control (RBAC) allows a KC super admin to assign specific permissions to individual admins. For instructions on how to configure admin permissions, see Administrators and roles.

Additional information

For more information on how KC changes app icons, see the Knox API documentation.
