How to disable Home button and keep your activity fullscreen?

Question

I am developing a lock screen in my application and i have the same problem as given in the following link How to disable Home button without using the TYPE_KEYGUARD?. I have used

public void onAttachedToWindow()
{  
    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD_DIALOG);     
    super.onAttachedToWindow();  
}

and added android:theme="@android:style/Theme.NoTitleBar.Fullscreen" in my mainfest.xml file. but still it is not working.

part of my mainfest.xml

<activity android:name=".LockActivity"  android:windowSoftInputMode ="stateAlwaysHidden"
    android:theme="@android:style/Theme.NoTitleBar.Fullscreen">

    </activity>

more details about my appliation is

my applications works in background and as i get the command my lock activity is displayed. but the problem is when i turn off my screen from power button and the command comes after that when i unlock the screen then either status bar appears or i cannot block my home button.
