I was wondering if there is a way to make an Android phone home button blink. This is because a lot of models don't have an LED light for notifications like my Samsung Galaxy W. This is a problem for me, so the idea is to make the home button blink on notification.
I doubt you can do this. Controlling the 'Home' button in this manner seems like it would be a security risk (for instance, you could pro-grammatically hide it if you wanted to lock someone in your app).
I am 99.9% sure you can't do what you are asking , which is why you are not finding it.

Hi I am planning to create an android app which is similar to the
Samsung Kids Mode- parental control
If you can see the link I gave, it is obvious that the app overrides the Home button when inside the app... I wanted to create a similar app for friends mode and stranger mode and should not come out of the app when home button is pressed... is it possible without root access?? My ultimate aim is to not come out of the app without entering a password, So if it is just an app after android 4.0 it just comes to the home screen when home button is pressed, So If I create a custom launcher and make it default even after pressing home button it will be inside the app if I am right, but is there any way I can do the same without a launcher
Also to avoid the phone number suggestions which happens when we dial parts of numbers in the dialler, should the phone be rooted to so it or is it possible without that?
Thanks in advance to everyone for taking time to read this, hoping a positive solution
How to create an android app that will appear on the lock screen and can be started even if the phone is lock?
Such that the application icon is visible on the lock screen instead of menu. Similar to emergency calls button on the lock screen.
Can anyone please help me out in this?
I read many things but was not able to find such thing please help me out.
Starting with Android 4.2, you can create lockscreen widgets. If the user places it on the lockscreen, it works mostly like any other widget.
I would like to make an icon counter for andoid just like the Email and the Samsung Apps applications i have seen such requests from other developers, but you all say it can't be done.
if so how come those 2 apps and other apps can do it?
do i have to make like more than one icon image and swap them or something?
is it really cant be done and why?
thanks.
you all say it can't be done.
That is because it cannot be done, except by the maker of the home screen, or via an app widget (instead of a launcher icon).
if so how come those 2 apps and other apps can do it?
Because Samsung wrote the home screen and can do what it wants with its home screen.
do i have to make like more than one icon image and swap them or something?
That will not work, as you cannot change the launcher icon at runtime.
is it really cant be done and why?
It really can be done by making an app widget, or by making your own home screen.
I'm working on my first android app. So far I have an activity that reacts to clicks on the hardware volume controls. That's was easy to do, but I'm wondering if there is a way to make it so the app responds to these events from the hardware buttons even while the phone is locked?
I'm really looking for a confirmation of whether or not this can be done. If someone could confirm and give me the general idea of how to do it that would be awesome.
I have not done exactly this but I believe that if you put
getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
in your Activity onCreate() you will be able to do what you want even if the screen is locked.
Today I am looking for a way to mimic the behavior I know from my HTC Hero's lock screen: the calendar and alarm clock can put text & drawables there to inform about an upcoming event or an expired alarm. The lock screen remains there in that it must be dragged down to dismiss the shown event and there might also be a Snooze button.
But, first question: is this default Android stuff or HTC Sense specific only??
Second question: If it is a common Android thing, why can't I find anything in Google's Android documentation for the topics "lockscreen" or "lock screen" that comes close to my question? Where's the API for it?
My problem is: I want to inform the user immediately - even if I try a standard notification, the user with a locked screen will have to unlock it and drag down the notifications list to see & clear what's going on. sigh Putting an endlessly playing notification sound there is a hassle as it takes at least two swipes down to stop the sound playing!
Any hints on this?
Thanks!

Sense specific only?
It is HTC Sense only. You cannot modify the lock screen of the device from SDK code -- only via firmware modifications. Sorry!
It's kind of o long way around the problem...
but the wallpaper is shown on then lockscreen. so you clould write a custom wallpaper to display your info on the lockscreen. (i think).
