java - Launching app on boot in android not working after update - Stack Overflow

I wrote an Android app, originally developed on Android 8.1 API 27. The App opens on boot. Now i'm trying to update the app to be compatible with Android 13 API 33, but i can not get the app to start on boot. Originally i used the method in this post How to start/ launch application at boot time Android but this does not work in the new version. I have tried using "AlarmManager" and "WorkManager" but have not managed to get it to work.

I do receive "RECEIVE_BOOT_COMPLETED" and the foregroundService starts, but the MainActivity is blocked from starting. Here is let Logcat output.

• Please be more specific on your problem, is the RECEIVE_BOOT_COMPLETED broadcast receiver not being fired or are you trying to do something else too? – tyczj Commented Feb 3 at 13:33

Background activity starts have been banned for several years except in limited scenarios.

I have tried using "AlarmManager" and "WorkManager" but have not managed to get it to work.

Those would also qualify as banned background activity starts.

Have your app be the designated launcher (<intent-filter> for the MAIN action and HOME category).
