Android disable all hardware keys for lockscreen app

Question

I am coding a custom lockscreen app for android.

I have managed to disable the back button. But the home button and the recent apps button on ICS proved not to be as easy.

I searched around and came up with:

@Override
public void onAttachedToWindow() {
    // TODO Auto-generated method stub
    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
    super.onAttachedToWindow();
}

However, this throws IllegalArgumentException window type can not be changed after it is added. I then tried to set it in onCreate() but the home key still functions.

I am willing to use root methods to achieve this. Is there any way to get it done?

Any help would be appreciated!

I'm more than sure you'd need root access and some low-level coding to do that. In other words, the Android SDK doesn't offer any way to do this. – Yvette

yeah WidgetLocker does this really well with root helper. But i just cant seem to find how – Tomika

For android versions above 2.3, overriding of the Home button is disabled
