Detect key home press from service

Hi i have broadcast application and I have a floating window
purpose: to view this window every activity I visit.
so my goal is that to minimize my floating window when I user press home button
SO my question is is there any way to detect if home is press?
if yes please guide me into it.
thanks in advance.
Pss.. I also tried to search it on this website but seems I haven't found a solution yet on it.
Note: it should be on service not in activity

How can I keep my app running when the focus is moved to another app or when the user presses the home button?

I have read other posts that suggest that I use a service but I am not sure that it will do what I need it to. I am trying to create an alarm app but once the user presses the home button, the alarm will never go off. Is there a way to keep my app running when the home button is pressed?
You should implement Service running in background (read this manual) or use an AlarmManager as suggested by Greg (that is better solution)

Android - Application closes on pressing power button

I have made an application named TicTacToe having AI. The problem is when I press my phone's power button and press it again to start my phone - what i notice is my app is closed and I see the home screen. I want my app to still run even after pressing the power button. ThankYou in advanced!
I think the app is minimized. Long press the home button the app is shown then click the app it will resume.
If by power button you do not mean turning the phone off, you can simply make use of the onresume and onpause functions. More detail on this: http://developer.android.com/training/basics/activity-lifecycle/pausing.html
If this is not working for you, try to log the runtime errors that the app gives and see if there are bugs in the code.

Android - Is It possible to disable the long click of home button to avoid the task manager?

I am looking for a way to disable the task manager window once I long press on the home button.
I managed to disable other device keys (such as volume, menu etc) and the normal click on the home button as I am the default launcher, but I don't know how to disable the task manager!
Even Toddler Lock kids app show u the task manager screen following long click, so I assume it isn't easy to do so.
I saw few answers say I shouldn't disable the task manager, but I want to have it from another key instead the long click on home button.
If needed and will solve my problem, I can be rooted.
Please help.
I found a way to do so with Android 2.3.5:
Override home and back button is case a boolean is true
(I used the piece of code from hotveryspicy)
But, as written in this link, this solution isn't working with Android 4.0.3
Can u help me to find a solution for 4.0.3 as well?
To avoid the recent app dialog on the long click home button, you can listen on focus of your activity. When your activity is loosing focus, fire an Intent.ACTION_CLOSE_SYSTEM_DIALOGS intent.

I hope this will help you :)

Reopening Android App from background with timer or countdown

Can someone point me in the right direction to have an Android Application reopen itself to the forefront after a user has pressed the home key? It should be able to be linked to some kind of countdown (which I already have setup, and runs when pushed to background).
I just can't find the function to force this action
*And yes, this is what the user will want, don't worry, I know this doesn't sound user friendly (forcing open) but in this case the user wants it.
Thanks
I needed the exact same thing before -> an app being displayed upon an event but I was sure I read on the Android developers site that this can't be done and that's what notifications are used for, although starting a new activity does bring an app to front. I found this link however to a NEW_TASK_LAUNCH flag with startactivity that might solve your problem -
