Cannot receive `BOOT_COMPLETED` intent when launching app A, but receive it when launching app B

Question

I am trying to launch a simple BroadcastReceiver by the BOOT_COMPLETED intent for Android 8.0, and using the Nexus 5X as emulator, no other service or class inside the project. I tried many solutions from Google but none of them work.

In summary, my problem is:

1) When I open the App A, the BroadcastReceiver of App A cannot receive the intent, but the BroadcastReceiver of App B can receive the BOOT_COMPLETED intent, .

2) When I open the App B, App A can receive the intent, but App B cannot.

Can somebody tell me what's happening? Thank you a lot.

Answer 1

For this BOOT_COMPLETE is not the solution as per documentation https://developer.android.com/reference/android/content/Intent.html#ACTION_BOOT_COMPLETED.
