And when I try to run below command
./adb shell dpm set-device-owner com.example.app/.receiver.AdminReceiver

it gives SecurityException

Can anybody please help to get out of this problem, I have removed all the accounts from mobile. I'm using redmi note 4 mobile

Answer 1

Having active accounts would result in different error, so it's not the case.

Please try to type in full path to receiver's package, eg com.example.app/com.example.app.receiver.AdminReceiver
