Android Question java.lang.SecurityException: Admin does not have

[ykucuk]

While developing an app using B4A and trying to utilize Samsung Knox APIs for Kiosk Mode, I encountered the following error:

java.lang.SecurityException: Admin  does not have com.samsung.android.knox.permission.KNOX_KIOSK_MODE

This error indicates that the app lacks the required permissions or configurations in the manifest to access the Knox Kiosk Mode functionality.

Manifest Code
Below is the manifest configuration I used:

AddManifestText(
<uses-sdk android:minSdkVersion="26" android:targetSdkVersion="34"/>
<supports-screens android:largeScreens="true" 
    android:normalScreens="true"
    android:exported="true" 
    android:smallScreens="true" 
    android:anyDensity="true"/>)        
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
