Hi there,
some people might shake their heads about this question but hopefully not too many.
Does someone know if screen capturing is a system function (maybe camera) that can be locked somehow or is it something that cannot be disabled because it is some peace of code that could run as app in the background (of course). In the windows world it is not easy but makeable with a hook or key lock in the system functions. In the Android world the system is pretty much shielded to the user. I had a discussion the other day with some folks in my office and they where talking about this saying it is possible but I doubt it.
What do you think/know.
As mentioned in above posts, if the app is running on a rooted phone, then it is probably quite easy to capture screenshots despite applying the mentioned SECURITY_FLAG to your activities.
