I'm building a reminder app. And when reboot the device, the alarms already have been set as pending intent in alarm manager is destroyed. So when reboot:
- Wake broadcastReceiver
- BroadcastReciever calls an Activity
- This Activity sets pending Intent again.
It worked well. However, I used an Activity, so this Activity shows up on the display a second after reboot. That's not really good. So I want to make this work on background.
Then, I noticed I can use IntentService.
However, IntentService is deprecated in API level 30.
Also JobIntentSerive is deprecated too.
I'm very confused. What should I use to make this work on background? Thank you.

You can reset the alarms directly in the BroadcastReceiver called at boot time. You don't need to launch any other components to do this.
