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

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

and in line number 48, I called a function startForeground(1, new Notification());

If you read carefully in the end of second line
requires android.permission.FOREGROUND_SERVICE
I was also facing the same error in one of my project I resolve it by adding permission in the manifest file. So just simply add foreground permission in the manifest file.
<uses-permission android:name="android.permission.FOREGROUND_SERVICE"></uses-permission>
Hope it's work for you.

Why App is not able to receive GCM Notification in Android O?

I am using the GCM inside my Application. But in Android O App stops receiving notification if it goes into background. I am using StartService for Lower API 26 and StartForgroundService for upper API 26 Android devices. Also tried JobSchedular and JobIntentService but still App is getting crashed with the below error.

Unable to start receiver com.google.firebase.iid.FirebaseInstanceIdInternalReceiver

My app integrates FCM to receive push notifications and it works okay. However, I am facing issue that on installation it crashes randomly. It is very random and occurring on OS 6.0+ devices till latest but randomly occurs.
Code wise, in service class only show notification code is written and added service in manifest.
I am getting below exception on app loads
