TYPE_SYSTEM_OVERLAY in ICS

In Honeycomb I was able to create a system overlay with TYPE_SYSTEM_OVERLAY and receive touches with FLAG_WATCH_OUTSIDE_TOUCH.

Now ICS has changed something. I can still create the system overlay, but i can't get touches.

Now, i am able to create the same with TYPE_SYSTEM_ALERT and get touches, but it just catches the touchevents, and not passing them on like in Honeycomb.

Any idea's?

Kind regards

Solution

  • Everything you describe is true. It is presumably to tighten up security, as the former behavior was the source of tapjacking attacks. I wrote a blog post recently about this change.

    Any idea's?

    Don't use either of them.
