Overlay a Full screen Transparent layer in Android 4.4(KitKat)

I want to overlay a transparent view on the entire screen including the bottom most Navigation Bar in Android 4.4.
I am able to do so in Android 4.3 by defining the window Manager LayoutParams as TYPE_SYSTEM_OVERLAY, but when I use the same definition the layout is now pushed behind the navigation bar. could you please let me know if it due to the recent updates in KitKat? or If any one have a solution please share with me.

The ActionBar in that screenshot is custom-made. It is not built using Android's ActionBar controls. It appears that it was created using a RelativeLayout with a custom background, 1 button on each side and text in the middle of the layout. You can do this as well, however, it is considered best-practice to use Android's ActionBar, which can be themed partially. (Background, text color, buttons, logo, etc...)
Since Android's ActionBar is relatively new, you should use ActionBarSherlock, which adds compatibility to Android 2.x.

You can customize the actionbar in android to a very good extent , give it a solid / gradient background , customize the font face , add buttons , event give to different round corner values, also tabs are available , i suggest that method so you don't need plug-ins

Android - Action Bar Style

I want to show Action Bar like below.
I have already used this library clickhere
But it takes only two icons on Action Bar. If I add four items, then last two are shown me like menu. I want all in Action bar same as image above.
Is it possible? if yes, then HOW? Can I change Action Bar color or its default style available in Device?
Thanks in Advance.

I recommend you use this:
http://jgilfelt.github.com/android-actionbarstylegenerator/
to style your ActionBar.
If you want all the 4 icons to be there, just add this attribute to all the menu items:
android:showAsAction="always"

hello try this library
it sure help you And you may have to add you own logic to handle this in below 2.3 Android OS and above 3.0 Android OS.
there is many demo sample available like below :

There is no way you can be sure of the number of icons displayed in the action bar. There is a large varierty of Android devices out there and they all have different screen sizes. That's why you have to prioritize the actions available in a menu : the most important will be displayed as actions in the action bars and the others will be displayed in the "menu" : the action overflow.
You should think of actions in a functional way, not a graphical way.

With ref to Image that you attached you should decide which design pattern you want to use in your application, there are many UI patterns available for mobiles, tablets. The image you attached looks like Side Navigation UI pattern. It's better you decide which UI pattern perfect for your app.. then start implementing it with custom action bar libs (if you want action bar in less than Android 3.0 ver) or any other.

P.S: I want to design on android 2X version. Please dont say refer to developer.android because i didn't find a satisfatory answer

You can use ActionbarSherlock for designing action bars for 2.x android versions. If you want action bar at the bottom, you can use split action bar which is supported by it.

Change logo that appears in Android ActionBar programatically

Is there a way to change the logo that appears in the ActionBar inside an Activity instead of listing it in the Manifest?
The reason I ask is I have an app for phones where I build a similar type of bar across the top with the launcher icon in the left corner similar to the ActionBar using an ImageView.
I also allow the user to change that image to one on their phone or on the internet. I am currently making the app work for tablets and would like to just use the ActionBar instead but can't figure out how to change the image based on the user. There is no method in the ActionBar class and I could not find a way to modify the icon or logo from the resources.
Anyone know if this is possible or could suggest something I could try?

Prior to the introduction in API 14 of the setIcon and setLogo methods that Jake mentions, you appear to be able to change the ActionBar logo by grabbing the view of android.R.id.home and setting a new drawable.
ImageView logo = (ImageView) findViewById(android.R.id.home);
logo.setImageDrawable(drawable);

API 14 introduced setIcon and setLogo methods.
As for 11 through 13 there's no easy way.
You could possibly use a custom navigation and hide the regular icon/logo by having your own layout mimic its functionality.
There is a homeLayout attribute in the action bar style which allows specifying an alternate layout resource to be used but it will always throw a ClassCastException since it is instantly cast to an internal class upon inflation (bug #21842).
