TYPE_SYSTEM_OVERLAY in Android 4 ICS

Question

My question is similar to the one here, TYPE_SYSTEM_OVERLAY in ICS

but is there any other way to achieve System overlay with touch events in ICS?

There are applications in the market which use overlay like,

Dock4Droid https://play.google.com/store/apps/details?id=com.urbandroid.dock

and

https://play.google.com/store/apps/details?id=mobi.conduction.swipepad.android

Answer 1

I see that TYPE_SYSTEM_ALERT still works on ICS and I need to come up with a solution using this flag.
