Start Android package in background with Android

hi all

iam using Android debug bridge on OH4.1.1 to start a Pipup program on Android TV. I am unable to start the program in the background. I can start the program using startpackage or the startintent channel. As a result, i have created a rule which starts the program and sends keypresses to get the previous program running. it kinda works. I was hoping for Android Debug Bridge to allow me to start the program in the background as well as to query the system and start Pipup if it is not running.
