Permission Denial : Starting Intent ( lock task mode / kiosk mode )

Question

Any one have a suggestion how to solve this error ? I am trying to run lock task with intent getLaunchIntentForPackage but I have no idea why this error is coming and which type of permission it wants to run this task.

java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10000000 pkg=com.example.videoplayer cmp=com.example.videoplayer/.MainActivity } from ProcessRecord{fd194a9 7523:com.example.lock/u0a190} (pid=7523, uid=10190) with lockTaskMode=true

I'm currently running into the same error. The only thing I can hand to you is that it can be solved by using the DevicePolicyManager.setLockTaskPackages as stated on the android site: https://developer.android.com/work/dpc/dedicated-devices/lock-task-mode#allowlist_apps
