I am working on an app which will be installed on tablets placed in public places like corners, shops. I want to hide the system navigation bar for restricting users from playing around in tablet. Is there any way to do this either programmatically or some other way?
I think there is already an answer to your question here: Is there a way to hide the system/navigation bar in Android ICS
I will just add that on some devices SYSTEM_UI_FLAG_HIDE_NAVIGATION does not work in that case you need to change some configurations in android itself to add the feature or maybe you can use ile's answer.

I want to design the Android App that will change the status bar of Android device as App opens like in iOS 7.
Can we make status bar changeable in Android?
Basically, no, the status bar in itself cannot be changed in Android by an application.
I guess that to be able to do that you'd need to make a custom ROM or maybe dive into the AOSP and find a way to do that on rooted phones.
I'm trying to make my app to Fullscreen (with no any bar) how I can coding to set it. (Android version 4.0.3)
Thx very Much
You can't hide that bar. On Honeycomb(3.0) there was a bug that would allow it to be hidden(on a rooted device), but it was fixed in ICS(4.0). (Note: see this answer for more techniques that worked on 3.0)As of now there is no way to do it on 4.0. Unfortunately, because devices no longer have physical buttons the navigation buttons (home and back) have to be put onto the screen. Because that bar contains the navigation buttons if you were to hide it, it would be possible to "lock" the user out of the device by not allowing them to leave your application(at least until they rebooted into safe mode).
So if you want to do that you'll have to make your own custom version of the OS to allow for it.
I want to make my application go fullscreen in any android device. Hide the Title bar and also the notification bar. The application is supposed to run on a 10 inch tablet on Android 4.0.3.
I am using the following code but only the title bar disappears. I want to hide the notification bar also. Can anyone please tell me what I am doing wrong in my code ?
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
try this
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
Hope it helps.
Edit:
The SYSTEM_UI_FLAG_HIDE_NAVIGATION is a new flag that requests the
navigation bar hide completely. Be aware that this works only for the
navigation bar used by some handsets (it does not hide the system bar
on tablets). The navigation bar returns to view as soon as the system
receives user input. As such, this mode is useful primarily for video
playback or other cases in which the whole screen is needed but user
input is not required
.
The thing holding the navigation buttons back and home, time, network information etc is referred to as "navigation" bar.
You can not hide it within the given framework, but it is possible if rooting the device is an option for you:
Root device
Install and run Busybox
Install HideBar
In HideBar there is an option to run in 'Kiosk' mode, in which there is no way to re-display the navigation bar. Needless to say, you really need to be careful with this.

I am developing an interactive video application using AIR on Android. The application is for at-risk communities to encourage them to get common cancer screenings, and will be deployed in clinics. I am testing and eventually deploying on the ASUS TF300, a 1280x800 ICS tablet.
When I put the app in fullscreen mode through a variety of methods it looks great, except the bottom bar of buttons does not hide, and instead displays as a black bar with "stealth" dots where the buttons normally present. I need to completely hide this bar so that users will not inadvertently navigate to home or other Android views.
I am having trouble solving this problem because I am not sure - Is it possible to EVER hide this bottom bar in ICS? If so, is there a known method for achieving this in AIR?
Many thanks for any advice.

I had the same issue, where I had to hide the system bar in a digital signage app for Android sticks for TV. I used distriqt native extension called Application.
Then it was as simple as using UI_NAVIGATION_HIDE in ApplicationDisplayModes class along with FULLSCREEN in my init function.
Just so you know, it is a paid extension, but worth buying the package as you get a lot of other good stuff along with it. I wasn't sure on where to begin with building my own ANE, so I went with distinqt.
Yes, it should be possible. After a few days of beating my head against the wall, I have this working on a cheap, Chinese android stick running ICS. The gist is that you need to create an Adobe Native Extension that runs the follow lines of Java:
Window window = context.getActivity().getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
Of course, you need about a dozen files of boilerplate to run those lines. Here's a good tutorial on building native extensions.
The name is system bar.

Unless you are using a rooted device you can't really removed them as they are user navigation controls.

I need to compensate for the lack of a physical (or even a "soft") menu button on Android 3 tablets. The app I'm working on generally hides the title bar for its activities, but I can't do that if I want the action bar to appear on a tablet. Is there something in the API that I can use to determine whether a device has a menu button?
If I can't find such a function, the only thing I can think of to do is to never hide the title bar on Android 3.0 and later, but that bothers me for two reasons:
I believe Android 3.0 (or a later API) will eventually support phones, which will probably have menu buttons
I would prefer not to hard code that SDK version (perhaps I could never hide the title bar for Android 3.0 and above, but then I run the risk of not hiding the title bar on phones)
LeffelMania has the right idea, but there is a caveat: If you target SDK 11 (3.0) and use a no-title-bar theme or override with a custom title of some sort, you will be just plain menu-less, because on Honeycomb devices with the target set to 11 the options-menu lives in the title bar itself instead of a fake menu button in the bottom status bar. So be careful there! (You can work around this by setting a lower target, or targeting style resources to v11 to use a one of the Holo themes with a titlebar in that case).
DEPRECATED: This answer is no longer accurate, given changes to the Android framework and design guidelines.
Android phones are guaranteed to have a Menu button. All phones pre-Honeycomb have Menu buttons, and Honeycomb features an ever-present software button. If you use the proper callbacks that tie into the Menu button (onCreateOptionsMenu(), onOptionsItemSelected(), etc) you will be safe to receive those callbacks on any device running Android.
As of API level 14, ViewConfiguration.hasPermanentMenuKey() is available to indicate whether a permanent menu key is present.
