Has anyone heard or has any idea about android's PRE_BOOT_COMPLETED Broadcast?

yes

yes

@tekashi @kescherRant Can you guys help me regrading what it is and if I can use it in my application.

Its a native android broadcast that happens after the os boots itself and its totally legal to use it in an application.

@tekashi This is the broadcast that is sent before Home app is launched?
How to use this in our app can you provide some link or something that might help.

If you can post these on devrant you can google them too but im feeling generous today so

@tekashi I think you got it wrong, I am asking about PRE_BOOT_COMPLETED not BOOT_COMPLETED.

@shandaar all that I could find about it is it is for system to use and can only be used by apps that are marked as system apps.
Check this: https://stackoverflow.com/questions...

It might be just so that if the system needs to do anything before actually booting its services?

Did not find any official doc about it :\

The more interesting question is why on god green (well. actually blue) earth are you trying to do?
The official Android API has "isUserAGoat" method.
So why would a UserLand app, that should never ever start at system boot, need something from the *PRE*_FUKIN_BOOT broadcast?

@magicMirror Actually there is a requirement where I need to show some screens after boot animation ends and default launcher application starts.
And I was just exploring the possibilities of how to do it.

@gitpush Yeah this is the only thing relevant I can find.

@shandaar You need to show animation before the standard app launcher starts? WTF?
The only reason I can think of to do that, is to fully replace the default launcher, bc nothing should show a UI before that. Explore that option.

@magicMirror I don't have to show animation but few screen after boot animation and before launcher app.

@magicMirror And I have thought of writing a launcher with integrated screens that I need to show.
I was just exploring other options that might be available

AFAIK - The only apps able to behave that way are the single use "welcome new user" System signed apps.
You need to be SystemOrSignature signed, and have special permissions, to be able to run before the standard launcher.

@magicMirror that is what the issue is, and we are trying to figure something out.
